摘要： An electric power steering system, and in particular a power-assisted steering system for a vehicle, comprises a steering transmission housing and a housing cover which forms an axial closure of the steering transmission housing and which is penetrated by an axially displaceable component of the steering transmission. In order to provide an electric power steering system which is easy to assemble and is not susceptible to wear, in an axially outer region of the housing cover, a first guide bushing for the axially displaceable component is integrated in the housing cover.

摘要： A superimposed steering system for a vehicle, e.g., a servo-assisted or power steering system for a motor vehicle, includes a differential drive, which is configured as a shaft drive and has a first input shaft and a second input shaft, for superimposing the rotational angles that occur in the first and second input shafts on an output shaft of the differential drive. The output shaft acts on an input shaft of a steering gear. The first input shaft interacts with a steering handle by a steering shaft and the second input shaft interacts with a servo motor. A superimposed steering system may apply an additional steering angle, without play, to the output shaft and may have a simple, cost-effective, space-saving construction, while being easy to install. The first input shaft is directly connected in a detachable manner to a radially flexible flex-spline of the shaft drive, the first input shaft passing through an eccentric drive core of the shaft drive, which extends into the radially flexible flex spline.

摘要： A steering valve (1) for power-steering gears contains two valve elements (4, 8), which are rotatable relative to each other. A corresponding centering unit (16) contains two centering elements (17, 18), which are rotation-fixed relative to the valve elements (4, 8) and which—together with the valve elements (4, 8)—are rotatable and axially displaceable relative to each other. Both centering elements (17, 18) feature radially aligned grooves, between which anti-friction elements (26) are inserted. Assembly is broken down into the following stages: The two valve elements (4, 8)—without centering unit (16)—are centrally aligned and linked via torsion bar spring (12). Separate from the steering valve (1), the two centering elements (17, 18) are pre-assembled in an assembly fixture and aligned in their mechanical center together with the anti-friction elements (26). The two aligned valve elements (4, 8) are linked to the two aligned centering elements (17, 18) by first linking the first centering element (17) to the first valve element (4), whereby the first centering element is aligned relative to the first valve element by means of a rotation-fixed axial guide element (20) and the link is non-rotatable but axially displaceable, and then linking the second centering element (18) to the second valve element (8) via longitudinal press fit, whereby the link is established by means of axial displacement of the entire centering unit (16) along the non-rotatable axial guide element (20).
