Abstract

A device for adjusting the level of a motor vehicle comprises an electric motor (4) and an actuating gear (3) which is connected upstream of a screw drive (2). The actuating gear (3) is formed by three series-connected gears (14, 15, 16) with parallel rotation axes (D14, D15, D16). An input gear (14), the number of teeth of which is at least one and at most five, is coupled to the motor shaft (17) of the electric motor (4) for conjoint rotation. The input gear engages with an intermediate gear (15) which engages with an output gear (16) which is connected to a nut (9) of the screw drive (2) for conjoint rotation.
