Actuator drive, especially for pivotal drive for mirrors in motor vehicles, has damping spring continuously connected to shaft region or gearbox element with frictional force produced by spring

摘要

The device consists of a housing, an electric motor (2), a reduction gearbox (3) and a damping spring (11) for attachment to or placing in contact with the housing. The damping spring is continuously frictionally connected to a region (9) of a shaft or a gearbox element (10) in one rotation direction and in the corresponding counter rotation direction and the frictional force is produced by the spring itself.
