Abstract
A clutch disk for motor vehicle main clutches, in which a disk member carrying the friction linings is torsionally elastically connected with a hub member, and in which several separate springs or spring sets with separate damping characteristics are provided; the springs or spring sets are thereby retained in windows provided in one of the two parts which are torsionally elastically connected with each other while the start of operation of at least one of the damping devices is determined by a sheet metal control member; a separate prestressed control spring is thereby coordinated to the control member.
