摘要： A chassis actuator adjusting a movably mounted component of a chassis, which has a first actuator component connected to the movably mounted component and a second actuator component connected to a fixed chassis component. The actuator components are adjustable axially by a ball screw that has a threaded spindle and a nut which runs on spindle. The nut is driveable by a drive motor that has a rotor coupled to the nut and a fixed stator arranged axially symmetrically with respect to the nut. The rotor is coupled to the nut by a wrap spring which radially surrounds the nut and via which the nut is rotated during rotation of the rotor and which forms a brake device. The brake device can be actuated by an external chassis force which acts on and rotates the nut and builds up a friction moment that counteracts the rotation of the nut.
