A friction disc clutch includes a radially extending Belleville diaphragm spring having its outer peripheral portion rigidly secured to a flywheel. In one preferred form, the diaphragm spring reacts against a fulcrum on the rear side of a pressure plate to effect engagement and release of a pull type friction clutch. A mounting portion integrally joined with the radially extending Belleville diaphragm spring, includes an annular rim for affixation to the flywheel. The result is a "cantilevered" Belleville spring action, wherein the forces obtainable are greater than those normally achieved by a Belleville having its outer portion unconstrained and hence free for axial deflection. |
