摘要： A system for lubricating a transmission for a vehicle includes an auxiliary oil reservoir placed in the transmission case apart from transmission gears, an oil pump in the transmission case operated interlockingly with an output shaft of the transmission for pumping lubricating oil stored in the bottom of the case into the auxiliary oil reservoir, and a circulating means provided in the auxiliary oil reservoir for regulating the amount of oil circulated from the auxiliary oil reservoir into the transmission case, such that the amount of oil in the auxiliary oil reservoir is increased or decreased in accordance with a respective increase or decrease in the amount of oil discharged from the oil pump. This system allows the amount of lubricating oil stored in the transmission case to be reduced in accordance with an increase in vehicle speed, while ensuring the transmission is lubricated to a sufficient extent at all times by an oil splash scattered from the gears over the vehicle's full operating range, while avoiding attendant power loss and excessive rise in oil temperature which may otherwise result during high speed operation.
摘要翻译：用于润滑车辆变速器的系统包括设置在变速器壳体中与传动齿轮分开的辅助储油箱，变速箱中的油泵与变速器的输出轴互锁地操作，用于泵送存储在变速箱底部的润滑油辅助储油器中的循环装置，以及设置在辅助储油器中用于调节从辅助储油器循环到变速箱中的油量的循环装置，使得辅助油箱中的油量增加或减少根据从油泵排出的油量的相应增加或减少。该系统允许根据车辆速度的增加来减少储存在变速箱中的润滑油的量，同时确保变速器始终通过从车辆上的齿轮散落的油飞溅被充分润滑工作范围，同时避免伴随的功率损失和在高速运行时可能导致的油温过度升高。

摘要： A multiple-disk clutch apparatus including an input-side rotatable member having a clutch disk pressing surface, a pressure plate attached to the input-side rotatable member and disposed on an axially rear side opposing the pressing surface, a plurality of clutch disks disposed between the pressing surface and the pressure plate with an intermediate plate being interposed between the clutch disks, and a stopper member for restricting an axially rearward return position of the intermediate plate at the time of clutch disengagement. The stopper member is mounted on the input side rotatable member via a one-way mechanism which allows an axially forward movement of the stopper member but which restricts an axially rearward movement thereof. A holder for holding the one-way mechanism can be mounted on the input side rotatable member so as to be movable axially rearward against a spring. A restriction portion for restricting an axially forward movement of the holder can be formed in the input side rotatable member. A shock absorbing member can be interposed between the restriction portion and the holder.

摘要： In a planetary differential gear system using helical gears, a clutch is interposed between a carrier for planetary gears and a differential casing, and adapted to be engaged by an axial thrust force produced by a sun gear. First and second axle shafts are provided with splined internal ends which are received in complementary bores of the sun gear and the carrier, respectively. The first axle shaft is received in a bore of the differential casing so as to be freely slidable and rotatable jointly with the sun gear. Therefore, the thrust force produced by the sun gear when a drive input is applied to the differential system can be transmitted to the friction clutch without being obstructed by the friction produced by the splined coupling between the first axle shaft and the sun gear, or disturbed by any unpredictable force of engagement between the first axle shaft and the sun gear. In this case, by providing a suitable arrangement for limiting a movement of the carrier in a direction to engage the clutch within a first prescribed range, it is possible to prevent any metallic contacts in the friction plates of the clutch even when the friction plates are substantially worn out.
摘要翻译：在使用螺旋齿轮的行星差速齿轮系统中，离合器介于用于行星齿轮的行星架和差速器壳体之间，并且适于通过由太阳齿轮产生的轴向推力而啮合。第一和第二车轴设置有花键内端，分别容纳在太阳齿轮和托架的互补孔中。第一车轴被容纳在差速器壳体的孔中，以便与太阳齿轮一起自由滑动和可旋转。因此，当将驱动输入施加到差速系统时由太阳齿轮产生的推力可以传递到摩擦离合器而不被第一车轴和太阳齿轮之间的花键联接产生的摩擦所阻碍，或被扰乱通过第一车轴和太阳齿轮之间的任何不可预测的接合力。在这种情况下，通过提供一种合适的布置，用于限制在第一规定范围内使离合器接合的方向上的载体的移动，即使当摩擦片是摩擦片时，也可以防止离合器的摩擦片中的任何金属接触大大磨损了
