Linear unit for applying axial operative force, has rotation-translation gear comprising threaded spindle and threaded nut that is non-rotatably supported, where threaded spindle is driven by electric motor

摘要

The unit has a rotation-translation gear comprising a threaded spindle and a threaded nut, and a brushless electric motor (1) provided with a rotor (12) and a stator (11), where the stator and the rotor are arranged in a housing (10). The threaded spindle is driven by the electric motor with a shifting clutch and/or a torque transmission clutch, where the threaded nut is non-rotatably supported. The rotor is formed with axial recesses that cooperate with projections formed at a clutch disk of the torque transmission clutch.
