ABSTRACT:
A friction clutch wherein a diaphragm spring is installed between two ring-shaped seats intermediate an axially movable pressure plate and a cover and has a circumferentially complete outer marginal portion extending beyond the seats and engaging with projections of the pressure plate. The spring has a radially innermost portion formed by an annulus of prongs whose tips surround an opening and which alternate with radially outwardly extending open slots. Such open slots alternate and overlap in part with the inner portions of closed slots whose outer portions are holes forming an annulus inwardly of the outer marginal portion. The regions of overlap between the open and closed slots include bridges which together constitute an annular tension spring enabling the diaphragm spring to store energy in addition to that which is stored in the outer marginal portion. The diaphragm spring can be tilted between the seats by a release bearing which cooperates with the tips of the prongs. Rivets, whose shanks extend through the holes of the diaphragm spring, secure the diaphragm spring and one or both seats to the cover.
