    • A piston anti-knock back assembly in a disc brake assembly having a brake actuator comprising a piston slidably mounted within a cylinder bore and operable to urge a fricton surface into contact with a rotary disc surface upon supply of hydraulic fluid under pressure to said cylinder bore, comprises an expanded resilient split ring in frictional contact with a main portion of the cylinder bore and loosely axially located in an annular piston groove adjacent a conical head of said piston. The resilient ring, when unexpanded, is a sliding fit within the main portion of the cylinder bore, and the outer peripheral portion of the resilient ring is shaped into a frustum of a hollow cone of sufficient depth that, when the ring is placed into contact with an end wall of the cylinder bore, the plane of the ring is spaced far enough away from the end wall to allow insertion of the conical head of the piston within the ring so as to expand the resilient ring up over the conical head portion until it snaps into position in said annular piston groove.
    • 一种盘式制动器组件中的活塞防回弹组件,其具有制动致动器,所述制动致动器包括可滑动地安装在气缸孔内的活塞,并且可操作以在将压力下的液压流体供应到所述气缸孔的同时将摩擦表面与旋转盘表面接触 包括与所述气缸孔的主要部分摩擦接触并且松散地轴向位于邻近所述活塞的锥形头部的环形活塞槽中的膨胀的弹性裂纹环。 当未膨胀时,弹性环是滑动配合在气缸孔的主要部分内,并且弹性环的外周部分成形为具有足够深度的中空锥体的平截头体,当环被放置成接触时 具有气缸孔的端壁,环的平面间隔足够远离端壁,以允许将活塞的锥形头插入环内,以便使弹性环向上延伸到锥形头部上,直到 它咬合到所述环形活塞槽中的位置。
