Speed-adaptive rotary vibration damper, in which a hub ring (1) and a rotating ring (2) enclose one another radially and are connected parallel to one another, at least temporarily, by column-shaped first and second spring elements (3, 4) which are distributed uniformly in the circumferential direction and consist of rubber, it being possible to expand the second spring elements (4) in the radial direction by the centrifugal forces arising with the introduction of high speeds, and to bring them into supplementary engagement with the rotating ring (2). Seen in the circumferential direction, the second spring elements (4) are delimited by a stop surface (6) which projects in the direction of the rotating ring (2) and engages in a congruent trough (7) of a third spring element (8) consisting of rubber, the third spring elements (8) being fixed on the rotating ring (2). The stop surface (6) and the trough (7) are at a radial distance from one another when the rotary vibration damper is not rotating. <IMAGE> |
