Abstract
A clutch disk for motor vehicle main clutches which includes a disk member carrying the friction linings and torsionally elastically arranged with respect to a hub member whereby for purposes of achieving a multi-stage torsional elasticity, several springs or spring sets with different characteristics are provided in windows of a hub flange or of the disk member and of a lateral member rigidly connected therewith which cooperate with correspondingly larger windows in the other of these two parts; friction damping means are thereby coordinated to these springs whose start of operation are determined by control means which engage into the corresponding windows or cooperate with the spring ends; only the friction of the friction device which has been engaged last, is thereby effective in the operating range whereby two friction devices are provided, of which the first friction device is operatively connected by means of its control spring with the hub flange while the second friction device is operatively connected by means of its control spring with the lateral members; the two control members are thereby connected with each other by a drag-type connection which becomes effective onl…
