ABSTRACT:
A clutch assembly comprised of a pressure plate, a hub, a retainer and a friction facing. The friction facing is secured to the pressure plate. The hub is disposed between the pressure plate and the retainer which is secured to the pressure plate by fasteners. Surface deformations are formed in the hub and the retainer. The surface deformations, such as indentations and projections, cooperate to provide friction damping and establish a spring force between the retainer and the hub. The circumferential excursion of the hub is fixed by the relative dimensions of the projections and indentations and the ramp shape of the indentations determines the rate of resistance. Increased friction damping can be provided by the addition of friction material to the surface of the retainer adjacent the hub. The inner diameter of the hub is splined for connection with a drive shaft.
