雪铁龙上世纪最科技的车 (雪铁龙发明专利)

上世纪，雪铁龙申请了一系列专利，包括气液联动控制汽车平衡行驶和在爆胎后的三轮行驶等一系列技术专利申请，这些技术虽然是60-70十年前技术，但是现在仍然有公司作为最新技术的发展进行宣传，让我觉得技术的发展果然也是螺旋上升的，比如美国60-70年代登月，但是现在的人怀疑是否其登过月，其实就是当时的一个技术顶峰，只是后来人不知道罢了，我们国家现在也在顶峰期，不知道我们的后人会不会也会怀疑我们现在的成绩。

Relates to an automatic device for maintaining a vehicle chassis frame at a uniform height from the ground irrespective of the vehicle loading and the flexibility of the springing. According to the invention, the piston of a hydro-pneumatic device is articulated to each wheel support, the two devices associated with each wheel set communicating with one another by means of a conduit and through a distributer, with a pressure accumulator, the wheel supports being connected to one another by means of an antirolling torque bar at approximately the middle of which is fixed a lever controlling the operation of the distributer to act on the hydro-pneumatic devices. As shown, each of a pair of road wheels 24 is carried by a suspension arm 1 controlled by a hydro-pneumatic spring device 3, 4, secured to the vehicle chassis frame. The arms 1 pivot about the axis of an anti-roll torsion bar 2 to which the arms are rigidly connected. Hydraulic liquid is supplied to or exhausted from both suspension devices 3, 4, under the a slide valve distributer D in dependence upon equally directed movements of the road wheels. The distributer comprises a slide valve 10 the movement of which is controlled by a lever 18 resiliently connected to the bar 2, to admit or exhaust pressure liquid from both suspension devices. Movement of the valve 10 is damped by flow of liquid through an opening 15 interconnecting a pair of chambers 13, 14. In a modification, Fig. 2 (not shown), an auxiliary torsion bar is arranged parallel to the bar 2 and the lever 18 is secured at one end to the auxiliary bar and partly surrounds the bar 2 as in the previous arrangement.

758, 761. Spring suspensions; preventing lateral canting. SOC. ANON. A. CITROEN. April 2, 1954 [Dec. 21, 1953], No. 9701/54. Class 108 (2). Relates to a hydraulic anti-rocking device for a vehicle having a wheel suspension system comprising wheel supporting members which are elastically sprung with respect to the vehicle chassis frame by means of springs or by means of pneumatic cushioning devices. According to the invention, the wheel supporting members for each pair of wheels on opposite sides of the chassis frame act on the pistons of a pair of hydraulic cylinders provided on the chassis frame, the displacement of the pistons by the wheel supporting members being cushioned by the springs or pneumatic cushioning devices, and that by means of a rotary pump inserted in a connecting pipe between the cylinders, liquid is transferred from one cylinder to the other under the control of a distributer which is operated by a predetermined movement of the wheel supporting members, the arrangement being such that liquid is removed from the cylinder on the less loaded side and delivered to the cylinder on the heavier loaded side of the vehicle. In the arrangement shown, in which a pair of road wheels 1, 1 is controlled by hydro-pneumatic suspension devices 7 operatively connected to wheel-carrying arms 2, the devices 7 are interconnected, through piping 9 and a slide-valve or rotary valve distributer 14, with a continuously rotating gear pump 8. The arrangement is such that increased loading on one side of the vehicle is resisted by transfer of liquid by the pump 8 from the device 7 at the other side of the vehicle. As shown, the distributer 14, controlling the direction of liquid flow comprises a rod 13 operatively connected to both arms 2, for sliding movement in the valve housing. The rod 13 is formed with reduced diameter portions 18, 20, 21 which, in the position shown, prevents liquid flow between the devices 7, but which under conditions of unequal wheel loading connects the pump delivery 15 to the heavier loaded device and the pump supply 16 to the other device.

811, 247. Hydraulic systems. CITROEN S.A., A. Jan. 18, 1957 [Sept. 14, 1956], No. 1894/57. Class 69 (2). [Also in Group XXXII] In an hydraulic system comprising a continuously operated pump P and two opencentre control valves D1, D2 each controlling the operation of a motor, a valve S is provided which automatically discontinues the supply of liquid to one control valve when the other valve is actuated to connect its associated motor to the pump, and automatically restores the supply to the one control valve if this valve is subsequently actuated. The control valves D1, D2 and their operation are identical. Considering valve D1, in the central position shown pump P discharges through valve S and a line 4 to this valve and thence through a line 37 to a reservoir R. A line 21 leading to an end chamber of the valve S is also connected to the reservoir through valve D1. Movement of the valve spool 24A to the left blocks the reservoir line 37 and opens a motor line (not shown) to line 21 and to the inlet line 4. The resulting increase in pressure in line 21 moves the valve S to the left, closing the supply line to the control valve D2, so that control valve D1 only is supplied. If the spool of the valve D2 is now moved to the left, so that both valves are actuated, its motor line is opened to a line 20 leading to the other end chamber of valve S, and the pressure in this motor line centralizes the valve S and both control valves are supplied.

The member 10a is. shaped to facilitate connection to a control member. If the spool 2 is moved, say in the direction of the arrow f, the plate 15a is moved away from the body 1 by a shoulder 18a and liquid is forced through the throttling orifice 16 from the left-hand chamber into the right-hand chamber. The return flow of liquid is not impeded because the pressure of the returning fluid moves the plate 15 away from the body member, until the mid-position is reached. Similar conditions obtain when the spool is moved in the other direction.

988, 242。离合器控制。安德烈?雪铁龙公司 1961年7月6日[1960年8月3日]，第24512/61号。标题F2L。活塞和气缸单元2、3的控制阀5通常通过离心调节器22根据发动机速度操作离合器1的释放杆，该控制阀5受到偏压弹簧8的作用，在施加制动器时，偏压弹簧8变得不起作用，以允许额外的压力液体进入气缸3以实现离合器的快速释放。如图所示，阀5分别控制与汽缸3和容纳弹簧8的腔室20连通的液体入口通道13和排出通道14以及另外的通道15和16。后者通常由轴向杆101压缩，轴向杆101从活塞10突出，活塞10由另一弹簧9保持抵靠气缸102的左侧端，气缸102通过管道191与车辆制动促动器192连通。调节器22分别由不可调节弹簧6和可调节弹簧7加载。在施加制动器时，管路191中的压力使活塞10抵靠弹簧9向右移动，从而卸载弹簧8并允许阀5向右移动并允许附加压力液体进入气缸3以快速释放离合器。

988, 242. Clutch controls. ANDRE CITROEN S.A. July 6, 1961 [Aug. 3, 1960], No. 24512/61. Heading F2L. The control valve 5 of a piston- and-cylinder unit 2, 3 operating the release lever of a clutch 1 in accordance with engine speed through a centrifugal regulator 22 is normally subjected to a biasing spring 8 which, upon application of the brakes, is rendered inoperative to allow additional pressure liquid to be admitted to cylinder 3 to effect rapid clutch release. As shown, the valve 5 controls liquid inlet and exhaust passages 13, 14, and further passages 15, 16, respectively, communicating with cylinder 3 and a chamber 20 housing spring 8. The latter is normally compressed by an axial rod 101 projecting from a piston 10 held by a further spring 9 against the left hand end of a cylinder 102 communicating by a pipeline 191 with the vehicle brake actuator 192. The regulator 22 is loaded by non-adjustable and adjustable springs 6, 7, respectively. Upon applying the brakes the pressure in line 191 moves piston 10 to the right against spring 9, thereby unloading spring 8 and allowing valve 5 to move to the right and admit additional pressure liquid to cylinder 3 for rapid release of the clutch.

A device for maintaining pressure in an accumulator Ac between two predetermined limits, the accumulator being supplied with fluid from a supply A past a non-return valve S and having an outlet Y to a circuit comprises two slide valves T1, T2 subjected at one end to accumulator pressure and loaded to the position shown by springs R1, R2 in separate chambers E1, E2. The spring R1 is calibrated to balance a force due to the lower limit pressure acting on valve T1 and spring R2 is calibrated to balance the upper limit pressure. The chamber E1 is connected to the supply A by a restricted passage F and to drain B by a passage H under control of the valve T2. The chamber E2 is connected to the drain B by a passage K and the valve T1 controls connection of the supply A to the drain B. In operation fluid is fed to the accumulator until its pressure reaches the upper limit when valve T2 moves downwards to open chamber E1 to drain. The fall in pressure in chamber E1 allows the valve T1 to move downwards and connect the supply A to drain B. When the pressure in the accumulator drops below the upper limit the valve T2 moves upwards but due to the restricted passage F, the valve T1 remains open until the pressure in the accumulator reaches the lower limit when the valve T1 again closes. If the fall in the accumulator is slow the valve T1 closes before the lower limit is reached.

汽车防侧倾装置

Anti-roll devices for automobile vehicles

1, 037, 312。防止车辆侧倾。雪铁龙。 1963年3月1日[1962年3月15日]，第8327/63号。标题B7D。一种具有动力转向的机动车辆设置有防侧倾装置，该防侧倾装置包括压力流体分配器40，该压力流体分配器40响应于动力转向控制缸10中的压力，选择性地将流体分配到车辆悬架中的气动或液压流体接收装置32、33，以使车辆朝向转向中心倾斜。如图所示，前轮的前臂3和后轮的后臂4通过扭杆30、31通过一侧的连杆34、35和另一侧的液压活塞缸装置连接。车辆液压回路还包括动力转向阀16和先导分配阀60，动力转向阀16控制向转向伺服缸10和分配器40的液压流体供应，先导分配阀60切断通过继动阀61向分配器40的流体供应，当达到预定的倾斜角时，在操作中，当转向阀16被操作成向右旋转时，例如，压力流体被供应到转向伺服缸室22，并且通过管线56供应到分配器40的室54，移动推杆51，如图1所示。 2，向上。这使得滑动阀41向上移动通过杆53，切断来自储液器18的管线43，通过导管45和管线46，并将其替代地与压力流体导管47连接，使得流体通过管线36流到装置32、33的下腔室，使装置32、33膨胀，并因此相对于车身向下推动左手轮，向上推动右手轮，如图1所示。 1，因此身体向右倾斜。为滑阀41、42设置止动件，使得当推杆51或52旋转杆53以将每个液压装置的一侧连接到流体压力源时，另一侧仍然通过管道45与储液器连通。当倾斜达到先导分配阀60的预定阀芯68时，分配阀60通过管线67与继动阀61的腔室65移动到右连接压力入口71，使得继动阀阀芯62从压力源移动到右关闭管线47，从而保持倾斜。当方向盘快速返回到直行位置或向左旋转时，转向阀16将流体供应到分配器40的腔室55以升高推杆52、使推杆51向下移动的旋转杆53、以及向上滑动阀42，使得液压装置32、33的上腔室加压并且装置收缩。在图1和图2所示的可选结构中。如图3、4所示，由于前液压气动弹簧80和后液压气动弹簧81连接在一起并且通过管线89、90连接到车辆高度调节装置，因此提供了附加装置以利用分配器401来防止在直线上行驶时的侧倾。为此，杆93连接在后悬架臂之间，后悬架臂具有接合滑阀411、421的凹口102、103的臂，使得杆93在旋转时提升一个滑阀而不压下另一个滑阀。在操作中，例如，当车身向右滚动时，杆93顺时针旋转提升阀421，使得压力流体从管线48通过管线44、37供应到装置32、33的上腔室，装置32、33收缩并因此将车身恢复到竖直位置，杆93在居中时切断压力流体供应。

1, 037, 312. Preventing vehicle roll. S. A. A. CITROEN. March 1, 1963 [March 15, 1962], No. 8327/63. Heading B7D. A motor vehicle with power steering is provided with an anti-roll device comprising a pressure fluid distributer 40 responsive to the pressures in the power steering control cyclinder 10 to selectively distribute fluid to pneumatic or hydraulic fluid receiving devices 32, 33 in the vehicle suspension to tilt the vehicle towards the centre of a turn. As shown, the leading arms 3 of the front wheels and trailing arms 4 of the rear wheels are connected by torsion bars 30, 31 through links 34, 35 at one side and through hydraulic piston-cylinder devices at the other. The vehicle hydraulic circuit also includes a power steering valve 16 controlling hydraulic fluid supply to steering servocylinder 10 and distributer 40 and a pilot distributer valve 60 which cuts off the fluid supply through relay valve 61 to distributer 40, with which it may be integral, when a predetermined angle of tilt is reached, in operation, when the steering valve 16 is operated to turn right, for example, pressure fluid is supplied to steering servo cylinder chamber 22 and through line 56 to chamber 54 of distributer 40 moving pushrod 51, Fig. 2, upwards. This moves slide valve 41 upwards through lever 53 cutting off line 43 from the reservoir 18 through duct 45 and line 46 and connecting it instead with pressure fluid duct 47 so that fluid flows through lines 36 to the lower chambers of the devices 32, 33 expanding them and hence pushing the left-hand wheels downwards and the right-hand wheels upwards relative to the vehicle body as shown in Fig. 1 and hence tilting the body to the right. Stops are provided for the slide valves 41, 42 so that when lever 53 is rotated by push rod 51 or 52 to connect one side of each hydraulic device to the fluid pressure supply the other side still communicates through duct 45 with the reservoir. When the tilt reaches the predetermined valve spool 68 of pilot distributer valve 60 is moved to the right connecting pressure inlet 71 through line 67 with chamber 65 of relay valve 61 so that relay valve spool 62 moves to the right closing off line 47 from the pressure supply so that the tilt is maintained. When the steering wheel is returned to the straight ahead position quickly or turned to the left, steering valve 16 supplies fluid to chamber 55 of distributer 40 to raise push rod 52, rotating lever 53 which moves push rod 51 downwards and slide valve 42 upwards so that the upper chambers of the hydraulic devices 32, 33 are pressurized and the devices contract. In the alternative construction shown in Figs. 3, 4, since the front and rear hydropneumatic springs 80, 81 are connected together and to a vehicle height regulating device through lines 89, 90, additional means are provided to utilize distributer 401 to prevent roll when travelling in a straight line. To this end a lever 93 is connected between the rear suspension arms having arms engaging notches 102, 103 of slide valves 411, 421 so that when rotated it lifts one slide valve without depressing the other. In operation, for example, when the vehicle body rolls to the right, lever 93 is rotated clockwise lifting valve 421 so that pressure fluid is supplied from line 48 through lines 44, 37 to the upper chambers of the devices 32, 33 which contract and hence restore the vehicle body to the upright position, lever 93 cutting off the pressure fluid supply when centralized.

A vehicle hydraulic transmission comprises a pump 2 supplying a motor 3 through flow and return lines 6, 7 and provides braking on overrun due to the action of a valve 13 which closes the return line 7 on overrun so that the return flow occurs through a by-pass line 18, 26 provided with a restriction 20 which is adjusted in accordance with the position of a brake pedal. The by-pass also incorporates a radiator 24. The valve 13 is subject to the pressure in the flow line 6 which is applied to a chamber 15 to urge the valve downwardly towards its open position against the force of a spring 21 and the pressure in the return line which is applied to a chamber 16. On overrun the fall of pressure in line 6 and rise in line 7 causes valve 13 to close the return line 7. The flow and return lines incorporate a reversing valve 30. In a modification the valve chamber 16 is subjected to an independent source of pressure. In a second modification (Fig. 8) a pump 205 for the vehicle servo system also selectively supplies the valve chamber 15 or 16 under the control of a valve 200 actuated by an accelerator pedal 203, the other valve chamber being opened to exhaust, the arrangement being such that the valve chamber 15 is pressurized if the accelerator pedal is depressed so that the valve 13 is open and the chamber 16 is pressurized when the pedal is released so that the valve 13 is closed and braking is provided.

1, 061, 379美元。液压机械变速齿轮及其控制足球。我是安德烈·雪铁龙。 1964年8月4日[1963年7月31日]，第31424/64号。标题F2D。在液力变矩器(1)和变速齿轮(3)的组合中，特别是对于布置在驱动轴(8)和从动轴(9)之间并在至少一个范围内提供仅液压机械比自动换档的机动车辆而言，每个具有至少一个齿轮接合位置的爪形离合器套筒(17a、18a)可分别在同轴相对可旋转轴(17、18)上手动滑动，所述同轴相对可旋转轴(17、18)可分别通过单向离合器(16)连接到变矩器涡轮(11)和通过变矩器旁通摩擦片离合器(5)响应于驱动轴速度和扭矩自动液压接合到变矩器的驱动轴(8)。虽然所示齿轮用于前驱动车辆，但驱动道路车轮的轴9通过锥齿轮传动装置，可以容纳向左突出的输出，如通过在5处使用小直径多盘离合器。所述变速齿轮可包括两个空套齿轮，所述两个空套齿轮不断地在从动轴上快速啮合，并提供一个具有一个自动换档的范围；或者，如图所示，齿轮35、36、37松开在轴17、18上，恒定地使齿轮38、39、40在从动轴上快速啮合，并在两个手动选择的范围内提供自动换档。虽然如图所示，手动低速档的自动高速比与手动高速档的自动低速比相同，但套筒17a、18a都可与齿轮38接合，后者可由提供不同速比的两个齿轮代替。变矩器包括在单向棘爪14上反应的反应器13。爪形离合器包括已知的同步装置，套筒17a、18a通过拨叉43、44在杆45上一起移动，杆45可通过换档杆46换档。为了倒车，惰轮(未示出)通过杆46分别与轴17、9上的齿轮54、55接合。旁路离合器5通过轴承30和杆28由气缸7a中的活塞31致动，气缸7a通过阀(33)(图3，未示出)从由转换器填充泵、分离泵或外部进料提供的流体压力源(32)加压。阀(33)由响应于驱动轴速度和扭矩的装置(34)控制。在低速范围内，随着套筒17a、18a分别向右移动到离合器齿轮35、36，到轴17、18，通过液力变矩器、单向离合器16、轴17和齿轮35、38驱动，直到旁路离合器5被速度和扭矩响应装置(34)和阀(33)自动接合，用于仅机械地通过轴25、离合器5、轴18和齿轮36、39驱动，单向离合器16松开。在套筒17a、18a分别向左移动到离合器齿轮36、37和轴17、18的高范围内，通过液力变矩器和齿轮36、39进行液压机械驱动，直到旁路离合器自动接合以便仅通过齿轮37、40进行机械驱动，单向离合器16松开。为了便于在车辆停止且发动机缓慢运行的情况下进行手动换档，电动开关(52)通过换档杆46的运动被致动以打开阀(51)，以将流体压力源连接到制动活塞缸，制动活塞缸作用在单向离合器16的驱动鼓15的周边上，从而制动变矩器涡轮11。杆46可以是柔性的或铰接的，使得开关(52)可以在杆45移动之前被致动。用于制动鼓15的控制器可替代地起到释放用于制动的元件的作用。为了便于在高速下手动换档，开关(52)被设置成关闭阀(33)并分离离合器(5)。当在液压机械驱动中换档时，驾驶员松开油门踏板，使得单向离合器16自动断开，从而消除了制动鼓15的必要性，当驱动轴速度足够高时，可以抑制(通过未描述的手段)鼓15的控制。

1, 061, 379. Hydro-mechanical variable speed gear and control. SOC. ANON ANDRE CITROEN. Aug. 4, 1964 [July 31, 1963], No. 31424/64. Heading F2D. In a combination of an hydro-dynamic torque converter 1 and a change speed gear 3, particularly for automobile vehicles, arranged between driving and driven shafts 8, 9 and providing automatic hydro-mechanical to mechanical only ratio shift in at least one range, dog clutch sleeves 17a, 18a each having at least one gear engaging position are manually slidable respectively on coaxial relatively rotatable shafts 17, 18, respectively, connectable to the torque converter turbine 11 through a one-way clutch 16 and to the driving-shaft 8 of the converter through a converter by-pass friction plate clutch 5 automatically hydraulically engaged in response to driving-shaft speed and torque. Whilst the gear shown is for a front drive vehicle, the shaft 9 driving the road wheels through a bevel gearing, a leftwardly projecting output may be accommodated, as by using a small diameter multi-disc clutch at 5. The change-speed gear may comprise two loose gears constantly meshing gears fast on the driven shaft and providing one range with one automatic shift; or, as shown, gears 35, 36, 37 loose on the shafts 17, 18, constantly meshing gears 38, 39, 40 fast on the driven shaft, and providing an automatic shift in two manually selected ranges. Whilst, as shown, the automatic high ratio of the manual low range is the same as the automatic low ratio of the manual high range, the sleeves 17a, 18a both being engageable with the gear 38, the latter may be replaced by two gears providing different ratios. The torque converter comprises a reactor 13 reacting on a one-way detent 14. The dog clutches comprise known synchronizing means, and the sleeves 17a, 18a are moved together by forks 43, 44 on a rod 45 shiftable by a gear-shift lever 46. For Reverse an idler gear (not shown) is engaged, as by the lever 46, with gears 54, 55, respectively, on the shafts 17, 9. The by-pass clutch 5 is actuated, through a bearing 30 and levers 28, by pistons 31 in cylinders 7a pressurized through a valve (33) (Fig. 3, not shown) from a fluid pressure source (32) provided by the converter filling pump, separate pump, or external feed. The valve (33) is controlled by a device (34) responsive to driving shaft speed and torque. Operation.-In Low Range, with the sleeves 17a, 18a rightwardly shifted to clutch gears 35, 36, respectively, to the shafts 17, 18, drive is hydro-mechanical through the torque converter, one-way clutch 16, shaft 17, and gears 35, 38 until the by-pass clutch 5 is automatically engaged by the speed and torque responsive device (34) and the valve (33), for mechanical only drive through a shaft 25, clutch 5, shaft 18 and gears 36, 39, the one-way clutch 16 releasing. In High Range with the sleeves 17a, 18a leftwardly shifted to clutch gears 36, 37, respectively, to shafts 17, 18, drive is hydro-mechanical through the torque converter and the gears 36, 39 until the by-pass clutch is automatically engaged for mechanical only drive through the gears 37, 40, the one-way clutch 16 releasing. To facilitate manual shift with the vehicle stopped and the engine running slowly, an electric switch (52) is actuated by movement of the gear shift lever 46 to open a valve (51) to connect a fluid pressure source to cylinders of brake pistons which act on the periphery of the driving drum 15 of the one-way clutch 16 and thereby brake the torque converter turbine 11. The lever 46 may be flexible or articulated so that the switch (52) may be actuated before the rod 45 is moved. The control for braking the drum 15 may, alternatively, act to release elements for braking. To facilitate manual range-shift at high speeds the switch (52) is arranged to close the valve (33) and disengage the clutch 5. When range-shifting in hydro-mechanical drive, the driver releases the accelerator pedal so that the one-way clutch 16 automatically disconnects, thereby negating the necessity for braking the drum 15, the control of which may be suppressed (by means not described) when the driving shaft speed is sufficiently high.

车辆液压制动系统

Vehicle hydraulic braking system

1, 087, 881。液压制动系统足球。马上。安德烈·雪铁龙。 1965年1月20日[1964年1月24日]，第2592/65号。标题F2F。一种车辆液压制动系统，包括分别连接到前制动器(6)和后制动器(7)的两个单独的流体回路，每一个包括流体蓄积器3或4和将流体馈送到相应制动器或制动器组的分配器装置5a或5b，分配器串联安装并可由公共踏板10操作，其特征在于，流体回路中的一个包括限制阀装置11，该限制阀装置11根据与其相关联的轴上的负载来限制施加到所述一个回路的制动器或制动器组的压力。限位阀包括在气缸13中的两个整体连接的活塞12和16，气缸13在所述活塞之间限定连接到后制动出口管线9a的第一腔室，以及通过具有安全阀15的旁通管线14连接到所述出口管线的另一腔室13a。活塞12上的轴向延伸部12a适于抵靠气缸的基部，而第二延伸部17a通过弹簧20连接到杆22的一端，杆22枢转到车辆底盘并在其另一端抵靠后轴24。在踩下踏板10时，由泵1从储液器2加压的蓄能器3和4通过相应的分配器5a和5b并沿着管线8和9分别将流体供给到前制动器和后制动器。传递到制动器7的压力也作用在活塞12下侧的腔室13a中。当该压力平衡弹簧20的作用时，活塞上升并闭合管9的端部，以将后制动压力限制为与弹簧20的压缩成比例的值，从而限制后轴24上的负载。如果在制动期间轴24上的载荷以及因此弹簧20上的载荷例如由于道路状况或车辆重心的移动而暂时减小，则活塞12和16的向上运动足够大，使得制动器通过管9a和18被排放到储液器，以防止车轮锁定。在一个修改的实施例中，如图2(未示出)所示，底盘和车轴之间的距离通过根据车辆负载修改波纹管压力而保持恒定的气动或液压悬挂波纹管连接到千斤顶(27)。千斤顶的活塞直接或间接地连接到阀延伸部17。阀装置11可以相对于底盘固定，或者阀装置11可以相对于轴24固定。

1, 087, 881. Hydraulic brake system. SOC. ANON. ANDRE CITROEN. Jan. 20, 1965 [Jan. 24, 1964], No. 2592/65. Heading F2F. [Also in Division F2] A vehicle hydraulic brake system comprising two separate fluid circuits connected to front brakes 6 and rear brakes 7 respectively, each including a fluid accumulator 3 or 4 and a distributer device 5a or 5b feeding fluid to the respective brake or set of brakes, the distributers being mounted in tandem and operable by a common pedal 10, is characterized in that one of the fluid circuits incorporates a limiting valve device 11 limiting the pressure applied to the brake or set of brakes of said one circuit as a function of the load on the axle associated therewith. The limiting valve comprises two integrally connected pistons 12 and 16 in a cylinder 13 defining a first chamber between said pistons connected to the rear brake outlet line 9a, and a further chamber 13a connected to said outlet line by a by-pass line 14 having a relief valve 15. An axial extension 12a on the piston 12 is adapted to abut the base of the cylinder whilst a second extension 17a is connected through a spring 20 to one end of a lever 22 which is pivoted to the vehicle chassis and abuts at its other end the rear axle 24. On depression of the pedal 10, accumulators 3 and 4, which are pressurized by a pump 1 from a reservoir 2, feed fluid through the respective distributers 5a and 5b and along lines 8 and 9 to front and rear brakes respectively. The pressure transmitted to the brake 7 also acts in chamber 13a on the underside of the piston 12. When this pressure balances the action of the spring 20, the piston rises and closes the end of the pipe 9 to limit the rear brake pressure to a value proportional to the compression of the spring 20 and hence the load on the rear axle 24. If the load on the axle 24 and hence spring 20 momentarily decreases during braking, due to, for example, road conditions or displacement of the vehicle centre of gravity, upward movement of pistons 12 and 16 is sufficiently large for the brake to be vented through pipe 9a and 18 to the reservoir to prevent locking of the wheels. In a modified embodiment, Fig. 2 (not shown), a pneumatic or hydropneumatic suspension bellows of the type wherein the distance between the chassis and the axle is maintained constant by modifying the bellows pressure as a function of vehicle load, is connected to a jack (27). The piston of the jack is either directly or indirectly connected to the valve extension 17. The valve device 11 may be fixed relative to the chassis or alternatively the valve device 11 may be fixed relative to the axle 24.

1, 095, 725. Clutch control. SOC. ANON. ANDRE CITROEN. Feb. 23, 1965 [Feb. 28, 1964], No. 7845/65. Heading F2L. An hydraulic circuit for simultaneous control of the friction main clutch and the engine throttle of a motor vehicle giving rapid initial engagement and gradual final engagement of the hydraulically disengaged clutch, the change point from rapid to gradual movement being determined by the engine throttle position, comprises, between a manually or automatically actuated gear ratio selection and clutch control valve 3 and a clutch disengaging jack 8, a device 1 having valve spools 6, 7 urged leftwards in a bore 48 by a spring 37 and the fluid pressure existing in the jack 8 and rightwards by a spring 27, acting through a lever 28, the tension of which spring 27 is controlled by the angular position of the engine throttle spindle 21 by means of a cam 22 and a lever 25. Movement of the valve 3 to a clutch disengaged position admits fluid pressure through a line 2, ports 43, 44, a chamber 35, and a line 46 to the clutch jack 8, and through a line 20 to a cylinder 15 where it acts to move a piston 16 leftwards against a spring 17 to act on the cam 22 to limit the engine throttle opening to e.g. 2/3 maximum, a sleeve 19 limiting the travel of the piston 16. The line 20 may include a one-way restrictor (Fig. 4, not shown) to prevent rapid throttle closure. Fluid pressure in the chamber 35 moves the spools 6, 7 leftwards to fully open the port 43 to the bore 48. The distance between the lands of the spools 6, 7 is slightly less than the distance between the ports 43, 44. When, for clutch engagement, the line 2 is exhausted by the valve 3 to a reservoir, the fluid from the clutch jack 8 passes rapidly through the port 43 until the jack pressure is overcome by the action of the spring 27 and the spools move rightwards to close the port 43. The remaining pressure is then released more slowly by leakage at a predetermined rate round the spool 7 from the port 44. The spring 17 returns the piston 16 to release the throttle. The tension of the spring 27 is adjustable by a screw adjusted opposing spring 30.

1, 108, 818. Hydrostatic transmissions. SOC. ANON. ANDRE CITROEN. 21 July, 1965 [28 July, 1964], No. 31093/65. Heading F2D. An hydrostatic transmission for a vehicle comprises swash plate pump and motor units 3, 10, the pump swash plate 5 carrying an abutment 28 acting as a reaction member for a compensating link 17 whose ends are acted upon by piston units 18, 25 respectively subjected to speed responsive pressure from an engine driven unit 21 and pump output pressure in line 7. In addition the pump and motor swash plates 5, 12 are acted upon by opposed pairs of piston units 41, 42 and 48, 49, the units 41, 48 being connected by lines 40, 47 to a distributer valve 32 and the units 42, 49 to the pump suction line 14. As shown the system is arranged for low speed conditions, the piston units all being in their uppermost positions for minimum and maximum tilting of the pump and motor swash plates 5, 12 respectively. Piston unit 41 is vented to atmosphere and unit 49 is connected to the right-hand chamber 35 of valve 32. With increasing speed the system pressure increases so that piston 25 moves to the right and valve 18 to the left and the pressure in chamber 34 operates valve 32 to cause pistons 41, 42 to move downwards to tilt pump swash plate 5 to the position for maximum capacity, Fig. 2 (not shown). At high speed pressure in chamber 35 causes valve 32 to operate to move pistons 48, 49 downwards, so that the motor swash plate 12 is tilted for minimum capacity. The pressure generator unit 21 is of the centrifugal type and the pressure may be modified by movement of the accelerator pedal, Figs. 4-11 (not shown).

In a motor vehicle change speed gear, such as described in Specification 1, 061, 379, wherein, for upshift, automatic actuation of a relay 5 responsive to engine speed and torque energizes a solenoid valve 12 to engage an hydraulically actuated friction clutch 3 and simultaneously energizes a solenoid 15 to close an auxiliary throttle valve 16 for engine torque reduction, a piston 13b in a cylinder 13a is acted on against a spring 13c by the hydraulic pressure effecting clutch engagement, the arrangement being such that only when the clutch is completely engaged is said pressure high enough for the piston to open, by its rod 13d, contacts 14 in the circuit of the solenoid 15 and thereby reopen the auxiliary throttle valve. A range-shift lever 1 selects Neutral, PM; Low Range, GB, for 1-2 automatic shift; and High Range, GH, for 3-4 automatic shift. In 1st and 3rd gear, drive is through an hydraulic converter/coupling (not shown) the turbine of which is connected to a shaft 2. In 2nd and 3rd gear, drive is through the hydraulically actuated friction clutch 3. In operation, with the vehicle stationary the hydraulic converter/coupling drives the shaft 2 at idling speed and a vehicle-stop detector switch 7 is closed. On shifting the lever 1 to Low Range, GB, closure of a shift lever switch 6 energizes a relay 8 through the closed switch 7 to open a solenoid valve 9 to apply an hydraulic brake 10a, 10b to the shaft 2 to enable 1st gear to be engaged. As soon as the vehicle travels at a predetermined speed, the switch 7 opens, the brake 10a, 10b being needed only for starting. On actuation of the automatic relay 5, a relay 11 effects the abovementioned clutch and auxiliary throttle valve operation. On continued vehicle acceleration, the lever 1 is shifted to High Range, GH, and drive is firstly in 3rd gear, through the hydraulic converter/ coupling, the relay 5 opening to effect exhaust of hydraulic pressure to disengage the clutch 3 and return of the piston-rod 13d in readiness for 3-4 shift.

In order to facilitate removal of pads from a spot-type disc brake one or both pads or preferably their backing plates have a pair of cylindrical surfaces curved to circular arcs about a common axis, corresponding surfaces having the same radii being provided on a frame or caliper supporting the pads so that limited pivoting of the pads about the common axis can occur, and at least one retractable abutment being provided which normally prevents such pivoting, the arrangement being such that when the or each abutment is retracted the associated pad can be pivoted to a position in which it can be slid clear of the frame or caliper in a direction parallel with the plane of the disc. As shown, a fixed caliper housing 2 is provided composed of two sections bolted together by mating portions 6, each section being bored or otherwise provided with a cylinder 8 (Fig. 2, not shown) in which works a piston 7 acting directly on the backing plate 9 of the appropriate pad 3. The backing plate is provided with cylindrical portions 11, 12 which co-operate with corresponding guide surfaces 13, 14 in the housing 2, the surfaces all having a common axis X whereby, on removal of an abutment in the form of a screw 16 threaded in the housing, the pad can be pivoted about axis X until clear of the surface 14 whereupon it can be removed tangentially from the housing. A fixed abutment surface 15 co-operates with screw 16 to retain the pad. The centre C of the friction surface is offset rearwardly from the cylinder axis, and the pad is symmetrical about a plane containing the axes X and C, so that in the normal direction of rotation of the disc the drag force F passes through or close to axis X. Fig. 4 (not shown) is similar excepting that the surfaces 11-14 are all of the same radius, so that axis X is concentric with the cylinder axis. In the embodiment of Fig. 5 (not shown) the radius of surfaces 11, 13 is only a little less than that of surfaces 12, 14, and both pads are retained by a single cotter 19 passed through apertures 19 in extensions of the backing plates, which are reversible. In the modification of Fig. 7 (not shown) surface 11 is concave and surface 12 convex, so that the surface 13 on the housing can be provided by a rod 22 fitted in the appropriate housing section, the arrangement otherwise being similar to that of Fig. 1.

1163134。车辆悬架足球。马上。安德烈·雪铁龙。 1966年12月2日[1965年12月7日]，第54174/66号。标题B7D。 [也在F2分区中]两个液体隔室11，隔板13具有泄放孔17和两个开口18， 18a，其具有延伸裙部20，图21和20A， 21a，阀杆19、19a具有纵向导管30、30a，纵向导管30、30a分别具有校准的入口孔31、31a和出口部件32、32a，并且导管30、30a设置有单独的入口通道29、29a，当阀克服弹簧25的作用而被提升时，这些入口通道29、29a被裙部20、20a逐渐关闭，并且如仅在入口通道29的情况下所示，当到达裙部20中的另一峰值限制孔22时，这些入口通道被重新打开。考虑到隔室11中的压力上升，当流速较小时，流体仅通过校准孔17。当压力增加时，阀19、26升高，打开隔间11、12之间借助于通道29、孔口31、导管30、出口32和裙部21内的腔室23的额外连通，使得压力/位移特性变平，直到通道29开始被裙部20关闭。隔室11中压力的持续增加使得通道29完全关闭，从而特性急剧上升。大大增加的压力使阀杆19充分升高，使得通道29与裙边22中的另一个孔22连通，以再次扩大液体流动面积，从而特性在其上端再次变平。阀19a、26a以类似的方式在相反的意义上操作。然而，在裙部20a中没有设置孔22，从而在特征的顶部没有设置弯曲部分。在油压气动减震器1中，如图1所示，在气缸9中工作的活塞8的杆7连接到用于车轮3的悬架的曲柄臂4、隔板13，隔板13具有阀，阀将气缸分成下空间11和上空间12以及容纳压缩气垫10的上空间12。如果悬架包括单独的支撑弹簧(14)，则图1和2示出了悬架的结构。如图2中未示出的，气缸具有补偿室而不是弹簧垫10，并且活塞承载一对控制阀，如所述。

1, 163, 134. Vehicle suspension. SOC. ANON. ANDRE CITROEN. 2 Dec., 1966 [7 Dec., ., 1965], No. 54174/66. Heading B7D. [Also in Division F2] Two liquid compartments 11, 12 of a shockabsorber are divided by a partition 13 which has a bleed orifice 17 and two openings 18, 18a which have extended skirt portions 20, 21 and 20a, 21a and which receive the stems 19, 19a of valves whose heads 26, 26a co-operate with seatings 24, 24a, the valve stems 19, 19a having longitudinal conduits 30, 30a with calibrated inlet orifices 31, 31a and outlet parts 32, 32a, respectively, and the conduits 30, 30a being provided with separate inlet passages 29, 29a which are progressively closed by the skirts 20, 20a when the valves are lifted against the action of the springs 25, and which, as shown only in the case of the inlet passage 29, is reopened as it reaches a further peak limiting-hole 22 in the skirt 20. Considering pressure rising in the compartment 11, when the flow rate is small the fluid passes solely through the calibrated orifice 17. As the pressure increases the valve 19, 26 lifts, opening up additional communication between the compartments 11, 12 by means of the passage 29, the orifice 31, conduit 30, outlet ports 32, and a chamber 23 within the skirt 21 so that pressure/displacement characteristic flattens until the passage 29 begins to be closed by the skirt 20. Continued increase of pressure in the compartment 11 causes the passage 29 to be fully closed so that the characteristic rises sharply. Greatly increased pressure raises the stem 19 sufficiently for the passage 29 to communicate with the further hole 22 in the skirt 22 to enlarge the liquid flow area again so that the characteristic flattens off again at its upper-end. The valve 19a, 26a operates in the opposite sense in a similar manner. However, no hole 22 is provided in the skirt 20a, so that a curved-over portion at the top of the characteristic is not provided. In an oleo-pneumatic shock-absorber 1, Fig. 1, the rod 7 of a piston 8, which works in a cylinder 9, is connected to a crank arm 4 of a suspension for a wheel 3, a partition 13, with valves as described, dividing the cylinder into lower and upper spaces 11, 12, and the upper space 12 accommodating a compressed gas cushion 10. If the suspension includes a separate support spring (14), Fig. 2, not shown, the cylinder has a compensating compartment instead of the spring cushion 10, and the piston carries a pair of control valves, as described.

A load-responsive hydraulic shock absorber for automotive or other vehicles equipped with an hydraulic suspension system, comprises a hollow body 1 filled with liquid, a fixed partition 4 separating said hollow body into two compartments 2, 3 of which one 3 is of variable volume, and valve mechanism controlling the flow, through suitable ducts 9, 9a, of the aforesaid liquid from one compartment to the other, the shock absorber being characterized in that said partition 4 comprises in a bore, constituting an auxiliary circuit, a slide valve 14 having one end responsive to the pressure of the liquid in said hollow body 1 and the other end responsive to a constant pressure exerted by resilient return means 16, said slide valve 14 being adapted, in predetermined positions, to open or close at least one auxiliary communication passage between said two compartments, said passage being controlled by said valve mechanism. The two series of ports 9, 9a are controlled respectively by oppositelyacting resilient disc-valves 12, 12a also controlling transverse ducts 11, 11a which lead into the ports 9, 9a and which are also controlled by the slide valve 14. The latter is slidably accommodated in a bore in a member 5 which is carried by a screw-on cover member 19 and which has a reduced diameter portion which extends through the valves 12, 12a, their backing washers 13, 13a, and through the partition 4 all of which are clamped together by a nut 20. The valve 14 has two areas of reduced diameter which form annular chambers 18a, 18 which communicate respectively with the upper and lower compartments 3, 2 through ports 6a, 6 in the member 5 which also has ports 7a, 7 which correspond with the transverse ducts 11, 11a. The valve 14 is biased into its lowermost position by a spring 16 so that the auxiliary paths A1, B1 in parallel with the main paths A, B through the ports 9, 9a and valves 12, 12a respectively, are open, the lower end of the valve 14 being subjected to the liquid pressure within the shock-absorber 8. With heavy vehicle loads the pressure of the suspension liquid becomes sufficient to raise the valve 14 against the spring 14 to partially, or completely, close the ports 6, 7a and increase the damping action. Gauged orifices 10, 10a are provided at inlets respectively to the two series of ports 9, 9a.

In an arrangement comprising a friction clutch in series behind a hydrodynamic torque converter in which the clutch is engaged hydraulically when liquid is supplied in one direction to the arrangement by way of a reversing valve and is disengaged when the reversing valve is actuated, a supplementary volume of liquid is supplied to give rapid clutch disengagement on actuation of the valve. As shown the turbine of a torque converter 1 is connected to an output shaft 5 by a clutch 3. A pump 23 supplies liquid to a reversing valve 7 at a pressure determined by a high pressure relief valve 25, the valve 7 being biased by a spring 11 to a position in which liquid is supplied through a line 26 to the interior of the output shaft 5 at a pressure determined by a low pressure relief valve 28. From the interior of the shaft 5 the liquid is led to the right hand side 4a of a pressure plate 4 to engage the clutch, and thence via the torque converter, the interior of the clutch, and an annular space between the shaft 5 and a sleeve shaft 6 to a line 27 and exhaust. On reversing the valve 7 by applying pressure through a line 13 to actuate a jack 9 controlling the valve, liquid is supplied through the line 27 to the interior of the clutch to disengage it. The jack 9 is itself constructed as a valve, and in its actuated position connects a high pressure line 13a to a line 13c leading to a chamber 19 of a device 14 having a piston 17 acting on a piston 18 of a larger diameter chamber 20 from which liquid is thus supplied to the interior of the clutch to supplement the disengaging liquid supplied by the pump 23. In a modification the jack 9 is a simple piston, the line 13 being directly connected to the device 14. In a modification of the device 14, the piston 18 is formed with a chamber 19 co-operating with a fixed piston.

1163972。控制变速齿轮；摩擦离合器足球。马上。安德烈·雪铁龙。 1966年12月20日[1965年12月23日；1966年3月29日]，第57056/66号。标题F2C、F2D和F2L。在具有至少一个由伺服操作的选档拨叉致动的比率确定的选档离合器的车辆变速齿轮中，摩擦离合器(10)在比率换档期间通过控制继电器(111)自动脱开，所述控制继电器(111)被可操作地连接到拨叉的构件触发，在选择器离合器和拨叉之间的空转连接确保在比率换档期间，对应于空转的拨叉的初始冲程触发继电器(111)以在换档之前脱开离合器(10)，继电器(111)在拨叉运动的对应于新比率的建立的端部被致动以使离合器(10)接合。发动机输出轴14通过液力变矩器11和液压致动摩擦离合器10驱动变速齿轮的输入轴1。平行的输入和输出轴1、2承载恒定啮合的齿轮对41-4、5-51、6-61，用于低前进比、中前进比和高前进比，齿轮3-31通过惰轮(未示出)连接用于倒档。齿轮3，4，5，6在它们的轴上是松动的，并且由双爪离合器7，8选择性地接合到轴上，双爪离合器7，8由叉50，51致动，叉50，51分别固定到换档杆52，53上，换档杆52，53由相对的活塞55，56和61，62致动，并由弹簧58，59，63，64推动到中间空档位置。每个叉以2J的轴向间隙接合其离合器。通过从手动或自动控制的选择开关97给相应的电磁阀ER、EI、EII、EIII通电，使液压流体从压力管线82进入活塞56、55、62、61中的相应的一个(倒档)、55、62、61(中档)，来建立每个比率。当未通电时，阀将其活塞连接到通向储液器G的排气管78。管路95、96使泄漏流体从阀返回。可与换档杆53、52中的凹槽106、108接合的杆110防止两个杆同时脱离空档。当中间或高接合时，可与杆53的凹槽106接合的杆105移位以在螺线管ER、EI的回路中打开触点100，而当反向或低接合时，可与杆52的凹槽108接合的杆107移位以在螺线管阀EII、EIII的回路中打开触点103。变矩器壳体12中的摩擦离合器10包括固定到轴1的从动盘19，从动盘19位于固定到变矩器涡轮16的输入构件17和压板18之间。板18和构件17形成通过管线22-24连接到离合器控制阀25的流体密封室21。壳体12形成围绕离合器10的第二腔室26，并通过管线27-29连接到阀25。阀25将腔室21连接到由泵36从储液器42供应的压力管线35，并将腔室26连接到返回管线44，返回管线44包括用于离合器分离的冷却器45。对于离合器接合，腔室26连接到压力管线35，腔室21连接到返回管线44，安全阀46在这种情况下打开以允许从变矩器到冷却器45的流动。当齿轮处于空档时，弹簧116将继动阀111的阀芯112保持在将压力管线82连接到阀25的腔室115的位置，使得活塞32抵抗弹簧31的作用将阀25的阀芯30保持在其离合器分离位置。当换档杆52、53中的一个移动到档位建立位置时，其上的台肩122-125中的一个经由杆120、121作用以移动继动阀滑阀，以将室115与排气管78连接，从而允许弹簧31将滑阀30移动到其离合器接合位置。在车辆静止、空挡档位和主离合器断开的情况下，开关97移动到接触CI以给阀EI通电，将压力流体引入活塞55以移动选档离合器7以接合档位4用于低速档。当换档杆52到达其行程的末端时，台肩122移动杆120以跳闸继动阀111，导致离合器10接合。 (使用触点CR以类似方式接合反向)。为了换挡到中间位置，开关97被移动到接触CII，断电阀EI，使得弹簧59使换档杆52返回到空档，初始运动以承担空档运动2j，使得台肩122在选择器离合器7分离之前释放用于离合器10分离的杆120。在选择器离合器7分离之前，开关97被移动到接触CII，断电阀EI，使得弹簧59使换档杆52返回到空档，初始运动以承担空档运动2j。在选择器离合器7分离之前，台肩122释放用于离合器10分离的杆120。保持触点(133)(图2，未示出)防止阀EII或任何其它阀通电，直到离合器10完全脱开。然后，阀EII通电，使活塞62移动选档离合器8，以接合中间齿轮5。当换档杆53到达其行程的末端时，台肩125作用在杆上以使继动阀111跳闸以用于离合器10接合。其他的转变也是类似的。自动离合器，例如离心式或电磁式，可以代替变矩器，并且离合器10可以通过控制电路的适当修改而被电磁致动。比率选择不必是顺序的。

1, 163, 972. Controlling change-speed gears; friction clutches. SOC. ANON. ANDRE CITROEN. 20 Dec., 1966 [23 Dec., 1965; 29 March, 1966], No. 57056/66. Headings F2C, F2D and F2L. In a vehicle change-speed gear having at least one ratio establishing selector clutch actuated by a servo-operated selector fork, a friction clutch 10 being automatically disengaged during ratio shifts by a control relay 111 tripped by members operatively connected to the fork, a lost motion connection between the selector clutch and the fork ensures that during a ratio shift the initial stroke of the fork, corresponding to the lost motion, trips the relay 111 to disengage the clutch 10 prior to the shift, the relay 111 being actuated for clutch 10 engagement at the end of the fork movement corresponding to establishment of a new ratio. Gearing.-An engine output shaft 14 drives the input shaft 1 of the change-speed gear via a hydrodynamic torque converter 11 and an hydraulically actuated friction clutch 10. Parallel input and output shafts 1, 2 carry constantly meshed gear pairs 41-4, 5-51, 6-61, for Low, Intermediate, and High forward ratios and gears 3-31 connected by an idler (not shown) for Reverse. Gears 3, 4, 5, 6 are loose on their shafts and are selectively clutched thereto by double dog clutches 7, 8 actuated by forks 50, 51 respectively secured to shift rods 52, 53 actuated by opposed pistons 55, 56 and 61, 62 and urged to central neutral positions by springs 58, 59, 63, 64. Each fork engages its clutch with an axial play of 2j. Gear control.-Each ratio is established by admitting hydraulic fluid from a pressure line 82 to a respective one of pistons 56 (Reverse), 55 (Low), 62 (Intermediate), 61 (High), by energizing respective solenoid valves ER, EI, EII, EIII, from a manually or automatically controlled selector switch 97. When not energized, the valves connect their pistons to an exhaust line 78 leading to a reservoir G. A line 95, 96 returns leakage fluid from the valves. Interlocks.-A bar 110 engageable with grooves 106, 108 in shift rods 53, 52 prevents both rods from being out of neutral simultaneously. A bar 105 engageable with the groove 106 of rod 53 is displaced to open contacts 100 in the circuits of solenoids ER, EI when Intermediate or High are engaged, and a bar 107 engageable with the groove 108 of rod 52 is displaced to open contacts 103 in the circuits of solenoid valves EII, EIII when Reverse or Low are engaged. The Friction Clutch 10, in the torque converter housing 12, comprises a driven disc 19, secured to the shaft 1, between an input member 17, secured to the torque converter turbine 16, and a pressure plate 18. Plate 18 and member 17 form a fluid-tight chamber 21 connected by lines 22-24 to a clutch control valve 25. The housing 12 forms a second chamber 26 surrounding the clutch 10 and connected to the valve 25 by lines 27-29. Valve 25 connects the chamber 21 to a pressure line 35, supplied by a pump 36 from a reservoir 42, and chamber 26 to a return line 44 including a cooler 45 for clutch disengagement. For clutch engagement, chamber 26 is connected to pressure line 35 and chamber 21 to return line 44, a relief valve 46 opening in this case to allow flow from the torque converter to the cooler 45. Main clutch control.-With the gear in neutral, a spring 116 holds the spool 112 of relay valve 111 in a position connecting pressure line 82 to a chamber 115 of the valve 25, causing a piston 32 to hold the spool 30 of valve 25 in its clutch-disengaged position, against the action of a spring 31. When one of the shift rods 52, 53 is moved to a gear establishing position, one of shoulders 122-125 thereon acts via levers 120, 121 to move the relay valve spool to connect chamber 115 with exhaust line 78, allowing spring 31 to move the spool 30 to its clutch engaged position. Operation.-With the vehicle at rest, gear in Neutral, and main clutch disengaged, switch 97 is moved to contact CI to energize valve EI, admitting pressure fluid to piston 55 to move selector clutch 7 to engage the gear 4 for low. As the shift rod 52 reaches the end of its travel, shoulder 122 moves lever 120 to trip relay valve 111 causing clutch 10 engagement. (Reverse is engaged in similar manner, using contact CR). For shift to Intermediate, switch 97 is moved to contact CII, de-energizing valve EI so that spring 59 returns shift rod 52 to neutral, initial movement to take up the lost motion 2j causing shoulder 122 to release lever 120 for clutch 10 disengagement prior to selector clutch 7 disengagement. Holding contacts (133) (Fig. 2, not shown) prevent energization of valve EII, or any other of the valves, until the clutch 10 is fully disengaged. Then valve EII is energized causing piston 62 to move selector clutch 8 to engage the gear 5 for Intermediate. As shift rod 53 reaches the end of its travel, shoulder 125 acts on a lever to trip relay valve 111 for clutch 10 engagement. Other shifts are similar. Modifications.-An automatic clutch, e.g. centrifugal or electromagnetic, may replace the torque converter, and the clutch 10 may be electromagnetically actuated, with suitable modification of the control circuits. Ratio selection need not be sequential.

In operation and on energizing valves 26, 27 valve 15 opens immediately to admit low pressure air at P 1 through valves 33, 34 to the cylinder space 1. After a delay, timer 32 allows valve 30 to open and a pressure buildup in cylinder space 1. Opening of valve 30 also results in closing of contacts 11 which starts the welding process after which valve 10 opens to allow build-up of pressure to P 3 in cylinder space 1. At the end of the welding operation, solenoid valves 26, 28 are de-energized resulting in valve 15 being connected to exhaust, valves 10, 30 being closed and valve 34 and cylinder space 1 being connected to exhaust thereby allowing piston 4 to be returned by its spring 20. A further compressed air circuit 35 includes a pressure reducer 37 and a manual control valve 36 whereby a pressure P 4 which is less than the low pressure P 1 is provided in cylinder space 1 and which pressure is low enough to allow the electrodes to be separated manually.

1, 187, 812. Hydrostatic transmission. SOC. ANON. ANDRE CITROEN. 9 May, 1967 [23 May, 1966], No. 21581/67. Heading F2C. [Also in Division F1] In a hydrostatic transmission for a vehicle wherein a variable displacement swash-plate pump 2 having a rotary cylinder block 4 supplies pressure liquid to two or more motors 36, 37, a driving gear 15 fast with the cylinder block 4 is driven from an input shaft (1) through a reduction gear (12), 15. The gear 15 may be integral with the cylinder block 4. The input shaft (1) may, Fig. 1 (not shown), be parallel to the pump axis and drive the cylinder block through straight or helically toothed gears (12), 15, or the input shaft may be perpendicular to the pump axis and drive the cylinder block through bevel gears. The rotary cylinder block 4 of the pump bears against the spherical surface of a fixed distributer plate 21 and carries pistons 6 which bear on the spherical surface of a non-rotary swash-plate 7. The inclination of the swashplate 7 is varied by supplying pressure fluid to a servo 61. A spring 32 acts through a sleeve 20 to bias the cylinder block 4 into engagement with the distributer plate 21. During normal running the spring pressure 32 is augmented by supplying pump output pressure to the interior of the sleeve 20 and during overrun the return pressure augments the spring pressure. The motors 36, 37 have radial pistons 40, 41 carried by output cylinder blocks 36, 37 and engaging eccentric rings 42, 43 freely rotatably mounted in housings 48, 49 which are pivoted about an axis 53 to vary the eccentricity of the rings 42, 43 and thus the displacement of the motors. Alternate pistons 40 (or 41) of each motor are oppositely inclined to a radial plane. Pressure fluid is supplied to the motors 36, 37 through a common distributer 28.

1, 200, 838. Variable-speed control. SOC. ANON. AUTOMOBILES CITROEN. 13 Dec., 1968 [20 Dec., 1967], No. 59527/68. Heading F2D. The control circuit fluid pressure of a motorvehicle automatic change-speed gear is regulated by a floating slide valve 36 responsive to the accelerator position A acting through an hydraulic device C to apply a first force f 1 to the slide valve 36, and a centrifugal detector D responsive to engine and/or vehicle speed to apply a second force f 2 thereto, the slide valve 36 being responsive to a third force f 3 formed by the automatic control circuit fluid pressure at E, which is applied, via a duct 46, and acts in opposition to the first two forces, whereby any resulting unbalance moves the slide valve temporarily to adjust and balance the control circuit pressure in accordance with accelerator position A and engine and/or vehicle speed, or, the third force f 3 may be effected by a spring (50) (Figs. 4 and 5, not shown) directly acting on the slide valve, the hydraulic device C modifying the slide-valve force f 1 according to the speed of depression of the accelerator A, whereby the faster the accelerator pedal depression the greater the reduction ratio automatically selected for increased vehicle acceleration, release of the accelerator A temporarily disconnecting it from the hydraulic device C which then retards further ratio change, whereby untimely and too frequent gear changes caused by irregular or jerky actuation of the accelerator are prevented. As shown, the hydraulic device C has a first piston 2, positively connected via a flange 7 and lever 30 to the accelerator pedal A only during depression thereof, a second piston 5, connected via a flange 6 and lever 33 to apply the force f 1 to the slide valve 36, and a third floating piston 10 connected via a spring 14 to the second piston 5 which is spaced from the first piston 2 and the cylinder base 18 by springs 13 and 17 respectively. The spaced pistons 5, 10, 2 form fluid-filled chambers 19, 20, 22 which are interconnected by orifices 24, 25 in the pistons 2, 10 and by limited flow leakage around the pistons, a by-pass line 23 incorporating a non-return valve 29 interconnecting the chambers 19, 22. Depression of the accelerator raises piston 2 and, via the fluid-filled chambers 20, piston 10 which forces fluid from chamber 19 to 20, via the by-pass 23, maintaining pressure balance in these latter chambers 19, 22, the pressure in chamber 20 increasing as the piston 10 is retarded during its movement by the spring 14, transmitting to piston 5 an effort adding itself to that of spring 13 biasing the flange 6 to reduce the force f 1 . Thus at any vehicle speed a rapid depression of the accelerator pedal down to a given position will tend to increase the reduction ratio more than when the pedal is slowly depressed to the same position, and still more than when the pedal is stabilized in this depressed position. On release of the pedal A, the piston 2 is urged by spring 13 &c. to compress the fluid in chamber 22, the by-pass 23 now being closed by the non-return valve 29, oil leaking from the chamber 22 via the orifice 24 and clearance 26 to slowly return the piston 2 to re-engage the pedal via arm 30. Thus, quick release of the accelerator is not accompanied by an immediate change (i.e. decrease), in the reduction ratio, whereby the smooth transition period damps out irregular pedal movements. Fig. 3 (not shown) illustrates a similar hydraulic device modified to connect the accelerator A at the opposite end of the cylinder. Further modifications (Figs. 4 and 5, not shown) illustrate hydraulic devices similarly operated by the accelerator A to act on a spring-loaded slide valve (49) the position of which directly effects ratio-change.
