数の下側ではアイドリング運転の要求に応じる。In a clutch plate for a friction clutch known from German Utility Model No. 8004841, a centrifugally controlled switching device controls the damping properties of the torsional vibration damper. The buffering characteristics respond to demands for load operation above the idling speed and to demands for idling operation below the idling speed.

Such torsional vibration dampers are used, for example, in conjunction with diesel engines, since they have a high degree of non-uniformity, especially during idling.

は駆動されず、このことによって騒音も発生しない。In order to solve such problems, in the present invention, the screw vibration damper of the friction clutch is designed only to buffer the vibrations generated in the torque transmission state of the transmission device, that is, during load operation. The device has a sensor that detects an idling state in which the output shaft of the transmission device is removed from the input shaft. Furthermore, the friction clutch can be engaged and disengaged by means of a controllable drive. The sensor controls the friction clutch in such a way that it is disengaged for the duration of the idle state of the transmission. During idling operation, the clutch plate and thus the transmission are not driven, so that no noise is generated.
