ABSTRACT:
A clutch assembly is disclosed in which an annular floater plate is mounted between a pair of pressure plates adapted to be engaged and disengaged with the floater plate to connect an engine-driven flywheel with a drive shaft. A plurality of shock canister units are mounted about the circumference of the floater plate and each canister unit includes an annular shock pad of a resilient material contained within a rigid cylindrical shell which in turn is mounted for axial sliding movement within arcuate sockets formed in the floater plate rim. The spindle of a drive bolt is mounted within each of the shock pads and the bolts in turn are threadably mounted on the flywheel so that upon engagement of the clutch assembly shock forces are absorbed by the canister units. The inner radius of the floater plate is isolated from the drive shaft for minimizing wobble which could otherwise occur due to misalignment of the elements, and thereby minimize friction and heat build-up. The floater plate is configured to be free of stress risers such as lubrication or mounting holes and sharp corners, and the outer rim of the plate is formed with a smooth curved contour so that cooling air is pumped by centrifugal action across the surfaces of the pressure and floater plates.
