Abstract:
1. An actuator for a wheel guiding element of motor vehicle wheel suspensions, with a first electrically driven actuating drive which selectively changes the length of the wheel guiding element, in the actuator there being a compensation spring which counteracts the compressive forces acting on the wheel guiding element, wherein the pretensioning force of the compensation spring can be changed by means of a second electrically driven actuating drive wherein the second actuating drive acts by way of an actuating pinion on the compensation spring; the actuating pinion which acts on the compensation spring is located coaxially to an actuating rod of a first actuating gear of the first actuating drive and is driven by way of the second actuating drive which is located adjacently and axially parallel to the first actuating drive with the actuating gear; and the compensation spring which is formed by a helical compression spring and which is located around the actuating rod is supported on a threaded nut which is guided on a stepped-down threaded sleeve.
