Abstract

An actuator for level adjustment of a motor vehicle utilizes a ball screw and a locking unit provided for blocking the ball screw. The actuator has a spindle drive which can be actuated by an electric motor via a gear. The spindle may be fastened to a damper of the chassis of a motor vehicle, to a wheel carrier or to the body or a subframe of a motor vehicle. With the aid of a locking unit of the spindle drive, the rotation of the spindle nut can be optionally blocked or enabled. The locking unit includes a locking element which engages a locking contour attached to the end face of a rotatable element of the gear.
