Abstract
This invention relates to a clutch disc with a torsional vibration damper, in which a control plate is used which, after a specified angle of rotation, comes into contact with the aperture of a spring element. Additional friction surfaces can be activated as a result of the presence of a control plate, which is capable of coming into contact on one of the components, i.e. the input part or the output part, with a friction element which is connected non-rotationally to the other of the two components.
