ABSTRACT:
A friction clutch comprises a cover member, a pressure plate mounted to the cover member by drive straps and a diaphragm spring interposed between the cover member and pressure plate so as to urge the pressure plate towards and into frictional engagement with a driven plate. The diaphragm spring has the usual outer belville portion and inwardly projecting fingers. The outer parts of the fingers themselves and particularly the junctions with the belville portion are stiffened by stiffening ribs which resist finger bending and thus reduce release travel. The ribs extend into and terminate within the belville portion without reaching its outer periphery. Fulcrum rings such as 17 incorporate raised bridge portions to provide clearance for the ribs.
