ABSTRACT:
A clutch driven plate assembly for an automotive vehicle wherein the clutch plate has radially extending lobes carrying friction pads of a suitable material, with the pad being mounted on cushioning means so as to present a variable surface contact area to the engaging surfaces of the clutch assembly to decrease the clutching capacity at initial engagement to reduce chatter. As torque demand increases and clutch engagement continues, the clutch capacity is increased by the deforming of the cushioning means to allow the friction pads to flatten against the engaging surfaces and provide a larger contact area.
