Electric damper for a motor vehicle

摘要

An electric damper for a motor vehicle for damping a relative movement between two components includes an electric generator for generating an induction voltage, the generator being drivable by the relative movement and having a rotor and a stator. The rotor includes a rotor shaft that is rotationally coupled to at least one rotor disk. A field-generating ring is provided in which elements that can be magnetized in segments are connected to the field-generating means such that the magnetizable elements are polarized alternately over the periphery of the ring. At least one coil ring with coil windings is provided which are arranged in segments, the coil ring and the field-generating ring being concentrically arranged.

1. An electric damper for a motor vehicle for damping a relative movement between two components comprising:
an electric generator having a rotor and a stator and being drivable by the relative movement for generating an induction voltage, said rotor having a rotor shaft connected in rotative fixed relationship with at least one rotor disk; a field generating ring having magnetizable elements provided segmentally in the field generating ring, said magnetizable elements being connected with field generating means so that the magnetizable elements are circumferentially polarized alternately over a periphery of the field generating ring; and at least one coil ring having segmentally arranged coil windings said at least one coil ring and said field generating ring being arranged concentrically.
