TORSIONAL VIBRATION DAMPER WITH TORQUE LIMITER, CONTAINING WET FRICTION LININGS AND STEP RIVETS

The invention relates to a torsional vibration damper (1) of a motor vehicle driven by an internal combustion engine, said torsional vibration damper being designed as a dual-mass flywheel and comprising a primary part (2) secured to a crankshaft and a secondary part (3) paired with an output side, wherein the primary part and the secondary part are arranged so as to be rotatable together about a rotational axis (4) and rotatable relative to each other, and a spring damper device (5) is arranged between the primary part and the secondary part in the torque flow. The secondary part (3) which is made of multiple pieces contains a torque limiter (13), the support flange (10) of which is coupled indirectly to an output hub (12) via at least one friction lining (24, 25) and a guide disc (15), and the output hub (12) is directly or indirectly supported axially against a friction ring (30, 42), which is connected to the primary part (2) via a support ring (31, 41), and is connected to a toothed sheet metal disc (17), which is mounted upstream of the guide disc (15), in a formfitting manner via a meshing engagement (23). An axial movement of the output hub (12) against a spring force of at least one disc spring (22) releases the meshing engagement (23) and interrupts a torque transmission of the torsional vibration damper (10), and the output hub (12) can then be rotated until the position of openings (28) of the output hub (12) matches the position of bores (11) of the primary part (2).
