Control member for a clutch disk of a motor vehicle main clutch

A control member for a clutch disk of motor vehicle main clutches in which a disk member carrying the friction linings and a lateral member rigidly connected therewith are operatively torsionally elastically connected with the flange of a hub member; several springs or spring sets of different characteristics are thereby retained in the windows of one of the two parts torsionally elastically connected with each other and engage in windows of the other part while frictional damping devices are provided, whereby the start of opertion of at least one damping device is determined by a control member which engages with tabs, arms or the like in the windows intended for the accommodation of the springs or cooperates with the spring ends; the control member includes an approximately radially extending fork-like arm whose two fork ends are bent over along their radial edges, as viewed in the axial direction, and therewith enclose a control spring; these bent over portions are supported at their radial inner ends with respect to the annular portion of the control member while two essentially mutually oppositely disposed axial angularly bent portions are provided, offset in the direction of rotation with respect to the fork like arm, for engagement in corresponding windows of the hub flange.
