Abstract
A clutch disk for motor vehicle main clutches which is equipped with a disk member carrying the friction linings and torsionally elastically arranged with respect to a hub member, whereby for a multistage torsional elasticity, several springs or spring sets with different characteristics are arranged in windows of one of a hub flange or of the disk member and of a lateral sheet metal member rigidly connected thereto, which cooperate with correspondingly larger windows in the respective other part; friction damping devices are thereby coordinated to the springs, whereby one of the friction damping devices is operable in the idling range and the others are operable in the operating range and the start of operation thereof are determined by control means engaging in the corresponding windows or cooperating with the corresponding spring ends; at least three spring stages of continuously harder characteristics, one friction device for the idling range and two separate main friction devices with control members for the operating range are thereby provided in the clutch disk according to this invention, whereby the control members are so constructed and arranged that the friction disk for…
