Abstract:
1. An electromechanical damper for a vehicle for damping between two components mechanical oscillations by which a drive torque is transmittable to an electric generator for generating a damping force, said damper comprising: a first gearbox constructed in the form of a planetary gear train having a sun wheel connected to one end face of a rotor of the generator, a ring gear, and planet wheels in mesh with the sun wheel and the ring gear; a second gearbox constructed in the form of a planetary gear train having a sun wheel connected to another end face of the rotor, a ring gear, and planet wheels in mesh with the sun wheel and the ring gear; and a stator housing forming a gear element which is integrated in the first and second gearboxes, wherein the sun wheel, ring gear and planet wheels of the first and second gearboxes are each provided with helical teeth in axial direction, with the helical teeth of the sun wheel of one of the first and second gearboxes and the sun wheel of the other one of the first and second gearboxes being directed in opposition to one another, wherein the ring gear of the first gearbox and the ring gear of the second gearbox form jointly with the stator housing a single-piece structure, with the planet wheels forming input elements of the first and second gearboxes via which input elements drive torques are introduced into the first and second gearboxes.
