Abstract

A tuned mass vibration damper included at least one damper mass and at least one guide component part to movably guide the at least one damper mass. The damper mass has a retaining component part which is at least partially arranged in a receiving recess of the damper mass. The retaining component part has at least one retaining structure and the at least one guide component part has at least one mating retaining structure to limit a movement of the at least one damper mass relative to the at least one guide component part in that the retaining structure and the mating retaining structure come in contact with one another. The at least one damper mass drives the retaining component part during a movement of the damper mass along a circumferential direction and to allow a relative movement of the retaining component part (350) with respect to the damper mass which results in a change in a radial distance of the retaining structure from the axis of rotation. The at least one damper mass and the at least one guide component part prevent the retaining structure and mating retaining structure from coming in contact with one another when an upper threshold speed is exceeded.
