Abstract
A rotation damper includes a damper housing that surrounds an electromagnetic damper motor which is disposed along a central axis of the rotation damper and which includes a rotor and a stator, and also surrounds means for generating a magnetic field on the rotor and the stator. The rotation damper further includes a coupling lever connected to a second mass, and a gear mechanism for transmitting and/or converting a relative rotation between the masses to the damper motor such that vibrations are dampened. The fastening part is connected to the damper housing for conjoint rotation therewith. The fastening part, along with the damper housing, is rotatably mounted on a bearing shaft-that is connected to the coupling lever. The gear mechanism and the damper motor are rotatably mounted on the bearing shaft

1-10. (canceled)
A rotation damper, comprising:
- a damper housing surrounding an electromagnetic damper motor comprising a stator and a rotor rotatably supported in the stator, said damper housing further surrounding means for generating a magnetic field on the rotor and the stator, said stator being fixed to the damper housing;
- a fastening part fastened on the damper housing in rotative fixed relationship with the damper housing and adapted for fastening the damper housing to a first mass;
- a coupling lever connected with a second mass;
- a bearing shaft connected with the coupling lever for supporting the coupling lever in the rotation damper;
- a gear mechanism for transmitting and/or converting a relative rotational movement between the fastening part on the first mass and the coupling lever on the second mass to the electromagnetic damper motor for damping vibrations;
- and
- rolling bearings rotatably supporting the fastening part together with the damper housing on the bearing shaft, a first one of said rolling bearings arranged between the bearing shaft and the fastening part, a second one of said rolling bearings arranged between the damper housing and the rotor, and a third one of said rolling bearings arranged between the rotor and the bearing shaft.
The rotation damper of clam 11, wherein the fastening part has fastening loops for fastening on a mass or the vehicle body.
