| 摘要 |
The invention relates to an absorber (125) for reducing a rotational irregularity, comprising a rotation element (130) which is rotationally mounted about a rotational axis (105), a damping mass (135) which is rotationally mounted about a rotational axis (105), and a first elastic element (140) which is arranged between the rotation element (130) and the damper mass (135) in order to counteract a torsion between the rotation element (130) and the damper mass (135). The invention also relates to a second elastic element (140) and to a coupling device (145), said coupling device (145) being designed to switch in parallel the second elastic element (140) with the first elastic element (140) when the rotational speed of the rotation element (130) reaches a determined side of a predetermined rotational speed threshold. |
