ABSTRACT:
A cover assembly for a diaphragm clutch is disclosed of the type comprising a plurality of stacked annular components: a cover, a diaphragm spring, a fulcrum ring and a reaction plate. The fulcrum ring is assembled on the cover by axial retaining tabs which extend through openings in the diaphragm spring and, for example, apertures in the fulcrum ring or in the cover. Resilient tongues or strikes are formed around the apertures or in the retaining tabs for transversely clamping the fulcrum ring relative to the cover. The arrangement permits assembly of the cover assembly by simple axial sliding engagement without having to bend over the ends of the retaining tabs after stacking the components. Alternatively, the retaining tabs and/or the resilient tongues may be formed in additional components fixed axially relative to the cover or the fulcrum ring, as desired.
