Cushion plate |
摘要 |
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.
