摘要： A power steering apparatus comprises a main valve member rotating in response to the action of a fluid pressure motor supplementing manual steering torque and a flap valve member rotating in response to the manual steering torque and mounted within the main valve member. The main valve member and the flap valve member are operable to control flow of fluid under pressure supplied into and discharged from the fluid pressure motor. A plunger member is slidably received in the flap valve member and is provided with an anti-vibration member. A passage communicating with a fluid supply port is provided for applying fluid under pressure to the plunger member to urge the anti-vibration member against the main valve member.

The inner peripheral surface of the bushing is coated by Teflon layer. With this structure, the frictional resistance between the shift fork and the fork shaft may be reduced, thus permitting the shift fork to be smoothly operated.

摘要： A transmission for an automotive vehicle, including a manually controlled main transmission and an automatically controlled subtransmission. The main transmission includes a main casing within which are rotatably supported a tubular intermediate shaft and a power output shaft, in parallel. Several gear wheels on each of these shafts cooperate, and by their selective engagement various different speed driving ratios may be obtained between the shafts. One end of the intermediate shaft and one end of the power output shaft project from one end of the main casing. A power input shaft passes coaxially through the tubular intermediate shaft and is rotatably supported therein. The ends of the power input shaft project from the ends of the tubular intermediate shaft. The subtransmission includes a subcasing attached to the aforesaid one end of the main casing, and within the subcasing a planetary gear mechanism is arranged between the power input shaft and the tubular intermediate shaft so as, under the control of a fluid pressure actuator, either to couple these two shafts together directly, or to provide an increase of rotational speed from the input shaft to the intermediate shaft. A fluid pressure control device selectively supplies actuating fluid pressure to the actuator, and is located within the subcasing in a position axially opposing the end of the power output shaft. The end of the power input shaft remote from the subcasing is driven. The fluid pressure control device is automatically controlled according to operational parameters of the vehicle to selectively supply fluid pressure to the actuator.

摘要： In a rack and pinion type steering system with an energy absorbing mechanism, errors in axial dimensions of the steering shaft and column tube often make it difficult to fix the two parts to each other at two predetermined axially spaced positions. Such difficulty is eliminated by providing an elongated slot of a predetermined axial length in the column tube to allow a holding member to extend radially through the slot irrespective of the dimensional errors to fixedly connect the column tube to the steering shaft. In addition, a support member which is mounted on the steering shaft for assembling a bearing thereon is constituted by a single structure to preclude disconnection or disintegration of component parts caused by the thrust acting thereon and provided with claw portions or caulking wall portions for holding the bearing securely in position.

摘要： A transmission has a drive gear shaft disposed coaxially with an input shaft which extends in parallel with an output shaft. Two pairs of meshing gears, one of which constituting a gear train of high speed gear ratio while the other constitutes a gear train of low speed gear ratio, are arranged for the torque transmission from the input shaft to the drive gear shaft. The drive gear shaft is connected to the output shaft through a plurality of meshing speed gear pairs such as first gear pair, second gear pair, third gear pair and fourth gear pair, as in the ordinary transmission. In operation, one of the gear trains of the high speed and low speed gear ratios is selectively engaged, so that each of the speed gears may be operated at either the high speed range or the low speed range. The transmission is small-sized, light weight and less expensive, thanks to the coaxial arrangement of the input shaft and the drive gear shaft and, therefore, can suitably be used in small-sized vehicles having limited installation space preserved for the transmission.
摘要翻译：变速器具有与输出轴同轴设置的驱动齿轮轴，输入轴与输出轴平行延伸。两对啮合齿轮，其中一个构成高速齿轮比的齿轮系，而另一个构成低速齿轮比的齿轮系，用于从输入轴到驱动齿轮轴的扭矩传递。驱动齿轮轴通过多个啮合速度齿轮对连接到输出轴，例如第一齿轮对，第二齿轮对，第三齿轮对和第四齿轮对，如在普通变速器中那样。在操作中，选择性地接合高速和低速齿轮比的齿轮系中的一个，使得每个变速齿轮可以在高速范围或低速范围内操作。由于输入轴和驱动齿轮轴的同轴布置，变速箱体积小，重量轻，成本较低，因此适用于传动装置保留有限安装空间的小型车辆。

摘要： An automatic power transmitting system for an automotive vehicle, wherein the operation of an electromagnetic clutch is automatically controlled in response to automatic shifting actions of a constant-mesh transmission by synchromesh devices. The powder clutch includes a driving rotor unit having an outer yoke and an inner yoke which cooperate to define therebetween an annular space in which a thin-walled cylindrical member of a driven rotor unit is disposed, such that the cylindrical member cooperates with at least one of the outer and inner yokes to define at least one powder gap. A small thickness of the cylindrical member assures a minimum of rotational energy consumption by the synchromesh devices. A damper may be disposed so as to connect the driven rotor unit and the input shaft of the constant-mesh transmission, so as to provide a damping effect for preventing a rapid change in an amount of torque transmitted from the driven rotor unit to the input shaft.

摘要： A die-cast transmission extension housing has an outer peripheral wall or whell and an integral bearing supporting partition wall provided transversely of the longitudinal axis of the shell between the open forward end and the closed rear end thereof. The partition wall supports at least a bearing for the transmission output shaft extending through the open forward end, the bearing on the partition wall and the closed end. The inner surfaces of the shell forwardly of the rear surface of the partition diverge to the open end of the shell so that the inner space defined by these inner surfaces and the partition can be moulded by a die-casting mould part which is slidable out of the inner space through the open end of the shell after the extension housing is die-cast. The upper wall of the extension housing is formed therein with an upper opening adapted to be closed by a shift lever retainer. The side and bottom walls of the shell cooperate with the partition wall to define a second inner space which is so shaped as to be moulded by another die-casting mould part which is slidable out of the second inner space through the upper opening after the extension housing is die-cast.
