ABSTRACT:
A clutch disc for motor vehicle main clutches with a disc member carrying the friction linings and torsionally elastically arranged with respect to a hub member, whereby for a multi-stage torsional elasticity, several springs or spring sets with different characteristics are arranged in windows of a hub flange and of the disc member as well as of a side plate rigidly connected therewith; friction devices are thereby coordinated to the springs, whose starting point of operation is determined by a sheet metal control plate which with tabs, arms or the like engage into the corresponding windows and/or cooperate with the spring ends; at least one friction device coordinated to a harder spring stage is thereby moved up in its operation into the range of the preceding softer spring stage by a corresponding predetermined play of the respective control plate with respect to the corresponding windows or spring ends.
