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.
