ABSTRACT:
The torsional shock absorber which is preferably suitable for a dual-mass flywheel comprises an input part (1) and an output part (21) which is rotatable round a common axis of rotation. Between control edges (43) of the input part (1) and control edges (41) of the output part (21), long load springs (23) designed for load running are arranged in an annular channel (15) which surrounds the axis of rotation and couples the output part (21) torsionally elastically to the input part (1). The output part (21) or optionally spring pots (25) provided at the face ends of the load springs (23) carry a peripherally resilient intermediate element (45) which projects beyond the control edges (41) of the part guiding the intermediate element (45) and rests on the control edges (35) of the other part. The control edges of these two parts are spaced from one another in the rest position of the torsional shock absorber, this spacing forming the operating range of the idling suspension. The idling suspension is bridged over once the spacing is used up.
