Abstract:
1. An electric damper for damping a relative movement between first and second masses, comprising: a generator driven by a movement of the first and second masses and having a fixed stator and a rotor rotatable relative to the stator, said generator having a hollow-cylindrical housing with first and second housing portions, with the first housing portion receiving the rotor and the stator; a gear mechanism coupled to the generator, with the second housing portion of the generator being connected to the gear mechanism, said gear mechanism having a lifting member movable in response to the movement of the first and second masses, at least one first gear element directly connected to the lifting member and caused to rotate in response to a movement of the lifting member, and at least one second gear element dynamically coupled by direct or indirect transmission with the first gear element, with the second gear element being dynamically coupled to the rotor of the generator such that the rotor ( a ring-shaped section associated to the gear mechanism for attachment of the gear mechanism to the housing, said ring-shaped section having at least one area in axial surrounding relationship to the housing and at least one area resting upon an outer side of the housing.
