ABSTRACT:
A diaphragm spring clutch cover assembly having a cover to be secured to a driven plate or flywheel and a pressure plate attached to the cover and urged by a diaphragm spring to press a driven plate against the driving plate in an assembled clutch. The diaphragm spring acts between a first fulcrum arrangement on the pressure plate and a second fulcrum arrangement on the cover. The first fulcrum arrangement comprises arcuate spaced lands in a circle on the pressure plate, a resilient wire ring engaged by the lands and spanning the spaces between the lands, and sleeves on the ring at those spaces. The sleeves are pressed axially of the clutch by the diaphragm spring so that during clutch reengagement the axial deformation of the spanning portions of the ring creates cushioning.
