Clutch disk for transmitting torque for friction clutch in commercial vehicle, has set of springs pre-stressed between input part and output part so that load torsional vibration damper compresses springs with torque

摘要

The disk (1) has a friction lining (3) for transmitting torque on the disk. Load torsional vibration dampers (7, 17) have two input parts (8, 19) skewed by impact of two sets of springs (10, 20) against two output parts (11, 21) up to two torque limits, respectively. One of the sets of springs is pre-stressed between one of the input parts and one of the output parts so that one of the dampers compresses the set of springs with the torque that corresponds to a part of one of the limits. A connecting element (27) connects the output part with the other input part for transmitting the torque.
