Abstract
A clutch disk for a friction clutch, especially for motor vehicles, has a driver disk with friction facings and a cover plate which is connected with the driver disk so as to be fixed with respect to rotation thereto. A hub disk and at least one control plate provided with two diametral arms are held between the driver disk and the cover plate. The hub disk, the cover plate and the driver disk are provided with windows in order to receive springs. The windows provided in the hub disk have, on at least one circumferential edge, a recess extending substantially in the circumferential direction. The arms of the control plate are provided with stop tabs on the radially outer side. The stop tabs cooperate with the radial outer region of the springs and, in the region of the stop tabs, the windows in the hub disk are enlarged along the circumference corresponding to the material thickness of the stop tabs.
