Actuator for motor vehicle, has electric motor with rotor assembled on nut of screw such that screw drives output shaft of motor in translation when rotor is in rotation, nut has inner diameter greater than outer diameter of motor

摘要

The actuator has an electric motor (28) with a stator (28a) disposed inside a rotor (31) of the motor. The rotor is assembled on a nut (42) of a screw (43) such that the screw drives an output shaft (23) of the motor in translation when the rotor is in rotation. The nut has an inner diameter greater than an outer diameter of the electric motor. The motor has an axis (28b) aligned with an axis (26) of the output shaft. An independent claim is also included for a motor vehicle axle including an actuator.
