ABSTRACT:
There is disclosed an improved release bearing assembly that is component of the pull-type clutch cover of a friction clutch mounted in an automobile. The release bearing assembly comprises a bearing body capable of moving axially within a given range, a retainer ring holding a diaphragm spring, a sleeve disposed between the bearing body and the ring, several resilient sheets extending from the flange of the sleeve axially of the sleeve, fingers formed at the front ends of the resilient sheets, and a release groove formed in the outer surface of the sleeve. The resilient sheets are circumferentially spaced from each other. The sleeve can slide on the bearing body between a first position and a second position. In the first position that is close to the retainer ring, the sleeve clamps the ring against the bearing body via the fingers. In the second position, the resilient sheets can play within a release groove formed in the bearing body, so that the ring disengages from the bearing body.
