  • Patent number: 7438168
    Abstract: A cushion plate is provided, for example, between a piston of a hydraulic servo and an adjacent friction plate in a frictional engagement element of an automatic transmission. The cushion plate is deflected by a pressing force of the piston to absorb an engagement shock. The cushion plate includes a main body portion formed into a belleville-spring shape, and a plurality of pawls that extend from the outer periphery of the main body for spline engagement with a member that is splined to, for example, the friction plate. A side wall of each pawl is formed with a curved recess extending circumferentially of the cushion plate and located adjacent the juncture (base) of the pawl at the outer periphery of the main body.

  • Patent number: 7309067
    Abstract: An input shaft, a stepless speed change unit, a forward-reverse switching mechanism, and an output shaft are arranged in that order in a power transmitting path of a continuously variable transmission. The forward-reverse switching mechanism includes i) a gear mechanism having a sun gear which rotates in the same direction as the rotation output from the stepless speed change unit, a carrier which is always fixed (stationary), and a ring gear which rotates in the reverse direction, ii) a clutch between the sun gear and the output shaft, and iii) a clutch between the ring gear and the output shaft. This structure enables the transmission of power between the gear mechanism and the stepless speed change unit and the vehicle drive wheels to be interrupted by the clutches when the vehicle is being towed or is stopped suddenly, and also obviates the need for a brake able to withstand a large amount of torque.
