Abstract: A clutch assembly for use with a vehicle's internal combustion engine, including a driving flywheel connected to an engine output, a driven flywheel rotatably mounted on the driving flywheel through a flanged bush, coil springs provided between the driving flywheel and the driven flywheel for imparting the rotational torque therebetween, and damping elements provided therebetween for absorbing vibration due to the fluctuating torque produced by the engine. The damping elements comprise a thrust washer, a friction plate and a dish spring which normally urges the driven flywheel toward the driving flywheel.

Abstract: The axially movable pressure plate for a disc clutch is comprised of an annular main pressure plate and an annular auxiliary pressure plate connected to each other by a plurality of radially disposed plate springs disposed intermediate the main plate and the auxiliary plate and having a wavy cross-sectional configuration in the circumferential direction tending to separate the main plate and auxiliary plate from each other and provide a cushioning effect when the composite pressure plate is shifted into engagement with the clutch disc. Additional plate springs having a similar wavy cross-section in the circumferential direction may be connected only to the auxiliary pressure plate intermediate the plate springs which interconnect the main pressure plate and the auxiliary pressure plate.
