摘要： A parking gear mounting structure for an automatic transmission includes an input shaft which is supported by a transmission case in such a manner as to be prevented from moving radially with respect to an axis of the input shaft, an output shaft which is arranged coaxially with the input shaft and is also supported by the transmission case in such a manner as to be prevented from moving radially with respect to an axis of the output shaft, and a planetary gearset provided between the input shaft and the output shaft. The planetary gearset has a pinion carrier which is provided with a parking gear in a fixed relationship thereto. The parking gear is engageable with a parking gear locking member for locking the parking gear when the transmission is in parking. The pinion carrier is mounted onto the output shaft to rotate as a unit with the output shaft. A connecting member is provided for transmitting driving power from the input shaft to the planetary gearset. The connecting member is in a fixed relationship to the input shaft. A bearing is arranged between the pinion carrier and the connecting member such that the pinion carrier is radially supported by the connecting member through the bearing to prevent a radial displacement of the pinion carrier with respect to the axis of the output shaft.

摘要： A bearing structure for an output shaft of an automatic transaxle employs a ball bearing, radial needle bearing and a thrust needle bearing in combination. The ball bearing and the radial needle bearing radially support the output shaft. On the other hand, the thrusting load to be exerted on the output shaft when it is driven by an output torque of the engine is received by the thrust needle bearing, and relatively small thrusting torque in reverse direction is received by the ball bearing. The ball bearing is provided on a side cover which is fixed to a transaxle casing. The radial thrust bearing is radially supported by the inner periphery of an output retainer. The thrust needle bearing is oriented at the opposite side to the ball bearing with respect to the output gear. A generally cylindrical retainer body having an axial end mating with a wall section of a transmission casing has a cylindrical projection extending from the axial end adjacent an inner circumferential edge. The cylindrical projection engages with an annular positioning groove formed on the inner periphery of the transmission casing. Fastening bolts extend axially to engage the axial end portion of the retainer for retaining the retainer on the transmission casing. The retainer defines a fluid path for supplying working fluid for a clutch drum. The fluid path opens to the axial end of the retainer so as to be connected with a fluid path defined through the transmission casing.
摘要翻译：用于自动变速驱动桥的输出轴的轴承结构采用滚珠轴承，径向滚针轴承和推力滚针轴承组合。滚珠轴承和径向滚针轴承径向支撑输出轴。另一方面，当通过发动机的输出转矩驱动时施加在输出轴上的推力负载被推力滚针轴承接收，并且相反方向的相对小的推力转矩被球轴承接收。滚珠轴承设置在固定在驱动桥上的侧盖上。径向推力轴承由输出保持器的内周径向支撑。推力滚针轴承相对于输出齿轮定位在与滚珠轴承相反的一侧。具有与变速器壳体的壁部配合的轴向端部的大致圆柱形的保持器主体具有从邻近内周边缘的轴向端部延伸的圆柱形突出部。圆柱形凸起与形成在变速器壳体的内周上的环形定位槽接合。紧固螺栓轴向延伸以接合保持器的轴向端部，以将保持器保持在变速器壳体上。保持器限定用于为离合器鼓提供工作流体的流体路径。流体路径通向保持器的轴向端部，以便与通过变速器壳体限定的流体路径连接。
