Sealing ring carrier for hydraulic rear piston of clutch of passenger car, has locking device comprising spaced fingers with free ends, which are moved by locking carrier in locking pit such that all linear degree of freedom are inhibited

摘要

The carrier (1) has a seal retainer (4) for a dynamic seal that is aligned to a pressure chamber. A locking device (7) is aligned to a pin- and ring-like movable component i.e. rear piston (2), moved by an operating pressure variably produced in the pressure chamber. The locking device comprises two spaced fingers (8, 9) with free ends (10, 11), which are moved by locking the carrier in a locking pit (12) such that all linear degree of freedoms (13-15) are inhibited. The locking device is fixed in rotary degree of freedom, and the carrier is made of plastic. Independent claims are also included for the following: (1) a movable component (2) a motor vehicle.
