    • In a torque converter, by devising a structure of a stator support mechanism, an axial dimension of a radially inner portion of the torque converter and surroundings thereof is reduced. The torque converter (1) includes a front cover (2), an impeller (3), a turbine (4), a stator (5) that regulates fluid flow from the turbine (4) to the impeller (3), and a stator support mechanism (6) that supports the stator (5) to be rotatable only in one direction relative to a fixed shaft. The stator support mechanism (6) includes an annular retainer (61) arranged on an engine side of a stator hub (52), an annular outer race (64) arranged at a radially inner portion of the stator hub (52), an annular first thrust bearing (66) arranged on a transmission side of the stator hub (52), and an annular second thrust bearing (67) arranged on the engine side of the stator hub (52) and at a radially outer portion of the outer race (64).

    • A hydrodynamic torque transmitting device is disclosed that overcomes problems created by the presence of a thrust washer therein. In a torque converter 1 according to the present invention, a piston 41 is disposed between a front cover 2 and a turbine 4 to form a front chamber F on a front cover side and a rear chamber R on a turbine side, and can move toward and away from the front cover 2 by means of a hydraulic pressure differential created between the front and rear chambers F and R. The piston 41 has a disk shaped body 41a, and a frictional coupling portion (friction facing 61) disposed on a outer peripheral portion of the body 41a that serves to frictionally engage with the front cover 2. The turbine hub 23 and the front cover 2 have opposing portions (63, 23b) that oppose each other across an axial space. The piston 41 has a support portion 48 that axially supports the turbine 4 when the piston 41 moves to a position near the front cover. When the piston 41 moves to a position closest to the front cover 2, an axial space is maintained between the opposing portions (63, 23b).
    • 公开了一种克服由其中存在止推垫圈而产生的问题的流体动力学扭矩传递装置。 在根据本发明的变矩器1中,活塞41设置在前盖2和涡轮机4之间,以在前盖侧形成前室F,在涡轮侧形成后室R, 并且通过在前后室F和R之间产生的液压差而远离前盖2.活塞41具有盘形主体41a和摩擦联接部分(摩擦面61),该摩擦联接部分 主体41a的周边部分,其用于与前盖2摩擦接合。 涡轮机毂23和前盖2具有跨越轴向空间彼此相对的相对部分(63,23b)。 当活塞41移动到靠近前盖的位置时,活塞41具有轴向支撑涡轮机4的支撑部分48。 当活塞41移动到最靠近前盖2的位置时,在相对部分(63,23b)之间保持轴向空间。
