ABSTRACT:
A friction clutch including a flywheel and a pressure plate which frictionally engage the driven disc assembly during use is disclosed. A pair of friction rings are mounted respectively on the flywheel and the pressure plate for engaging the driven disc assembly therebetween. Each of the friction rings includes a rigid backing plate having a first friction element secured to one face thereof and a second friction element secured to opposite face thereof. The first friction elements are formed from a material having a relatively low coefficient of friction, while the second friction elements are formed from a material having a relatively high coefficient of friction. Retainers are provided for retaining the friction rings to the flywheel and the pressure plate, while permitting restricted relative rotational movement therebetween. When the clutch is engaged, the second friction elements rapidly engage the driven disc assembly, causing the friction rings to initially rotate relative to the flywheel and the pressure plate. After this initial engagement is complete, the driven disc assembly and the friction rings all rotate together as a unit with the flywheel and the pressure plate.
