Abstract: The invention relates to an electrical power steering system for a motor vehicle with a steering housing, in which a gear system is arranged, wherein a bar mounted such as to be displaceable longitudinally in the housing is a gear element for actuating steerable wheels, and wherein the steering housing is closed off by at least one folding bellows element, which is secured on one side to the steering housing and on the other side to the bar. Rapid pressure compensation in the event of temperature change is guaranteed, because a hose is connected at one end such as to communicate with the interior volumes of the steering housing, and when in operation is secured at a second free end above the steering housing.

Abstract: A rack and pinion steering gear comprising a thrust element disposed in a housing for pressing a rack and pinion against one another. One side of the thrust element is supported against the rack, and another side is supported against a wedge-like part formed of two semi-circular annular elements, each of which is provided with at least one wedge surface that is disposed at an angle to a central plane of the wedge-like part. A side of the wedge-like part remote from the thrust element is supported against a set screw. The thrust element and/or the set screw is provided with an inclined surface that cooperates with the at least one wedge surface of the annular elements of the wedge-like part.
