Abstract
A friction clutch assembly comprising a resilient annular member adapted to be engaged by a clutch release bearing to control axial movement of a pressure plate relative to a cover is disclosed. The resilient annular member comprises tabs which extend axially through apertures in the cover to provide said annular member with a fulcrum. Each tab defines a free end which is bent before assembly and resiliently deformable in an axial direction, whereby the cover is axially prestressed by the tabs after assembly. In a preferred embodiment of the invention, the apertures comprise a first portion permitting axial introduction of the tabs and a second portion permitting rotation of the annular member in a given direction relative to the cover, bent portions of the cover preventing the annular member from rotating in the reverse direction. In another embodiment, a locking ring is inserted between the free ends of the tabs and the cover to prevent the tabs from escaping through the apertures.
