Rotational Vibration Damper, Particularly For The Power Train Of A Vehicle

摘要

A rotational vibration damper includes a primary side (32) and a secondary side (46) which is rotatable with respect to the primary side (32) around an axis of rotation (A) against the action of a damper element arrangement (28). At least one damper element unit (42) of the first group (70) and at least one damper element unit (42′) of the second group (70′) are pre-loaded, and the primary side (32) and the secondary side (46) are pre-loaded in a basic relative rotation position with respect to one another. Proceeding from the basic relative rotation position of the primary side (32) with respect to the secondary side (46), a pre-loading path (V, V′) of at least one pre-loaded damper element unit (42) is shorter than a maximum relative rotation path of the primary side (32) with respect to the secondary side (46).
