ABSTRACT:
A clutch assembly having an annular cover member attached to an engine flywheel, an annular pressure plate which is floatingly attached to the cover member by a plurality of drive straps, a friction drive assembly which is splined to a transmission shaft for rotation therewith and sliding movement therealong, and which is positioned between the pressure plate and the engine flywheel, a plurality of radially extending release levers, each of which is pivotably attached to the cover member at a location between the ends of such release lever, and a belleville spring trapped between the cover member and the release levers to normally bias the release levers so that the outer end of each of them imposes a load on the pressure plate which tends to urge the pressure plate against the friction drive assembly and the friction drive assembly against the flywheel, each of the drive straps having an outwardly projecting extension which is positioned between the pressure plate and the outer end of an adjacent release lever to prevent the outer end of the release lever from imposing wear loads on the pressure plate.
