Abstract
A clutch assembly has a central driving plate fixed to a hub and a pair of interconnected lateral plates arranged on each side of the central plate, one of which carries friction linings. A number of corresponding windows are formed in the driving plate and in the lateral plates which receive coil springs which form a torsionally-resilient torque-transmitting connection between the central plate and the lateral plates, and the lateral plates are interconnected by integral feet formed on one or both of the plates from the material removed to form the windows therein.
