| 摘要 |
The invention relates to a tuned mass damper (340) which, according to an exemplary embodiment, for example, for a drive train of a motor vehicle, for damping an oscillation portion of a rotational movement, comprises at least three damping masses (110), at least one guide component (600) configured to movably guide the damping masses (110) such that the damping masses (110) are arranged in an offset manner along a circumferential direction. Said tuned mass damper further comprises a dimensionally stable spacer component (660) that can be rotated with respect to a guide component (600) about a about an axis of rotation of the rotational movement, which is connected to the damping masses (110) in a form-fitting connection with clearance, which are configured such that starting from a center position of the damping masses (110) to the spacer component (660), in the event of an oscillation of one of the two damping masses (110) to overcome a clearance of the connections of two of the damping masses (110) to the spacer component (660), the spacer component (660) is rotated along the circumferential direction such that the spacer component (660) takes along the other of the two damping masses (110) along the circumferential direction. |
