An electromechanical servo steering system may include an electric servomotor that drives a worm shaft that meshes with a worm wheel arranged on a steering shaft. The worm wheel is operatively connected to an input shaft of a steering gear mechanism, and the worm shaft and the steering shaft are rotatably mounted in a common gear mechanism housing. The worm shaft has a free end that is remote from the motor and an end that is close to the motor. The end that is remote from the motor is mounted in a rolling bearing, and the end that is close to the motor has a rolling bearing that is received in an eccentric lever.

The invention relates to a steering system for a motor vehicle with electrical power assistance comprising: a steering-spindle bearing unit, in which the steering shaft is mounted rotatably and is guided in a slide, which can be connected to the vehicle body, wherein the steering-spindle bearing unit is adjustable at least in its inclination, an electric motor, which is coupled rotatably via reduction gearing to a steering spindle, wherein the reduction gearing is enclosed and mounted in a housing, wherein the housing has means for forming a swivelling axis, about which the steering-spindle bearing unit is adjustable in its inclination, wherein the steering system further comprises a retaining clamp for fastening the steering system to the motor vehicle, wherein the retaining clamp has a guideway that interacts with a counterstay arranged on the slide, wherein the slide is movable along the guideway after it overcomes a presettable releasing force, and in the case of displacement of the slide along the guideway, the swivelling axis is moved upwards relative to the retaining clamp.
