A rack-and-pinion steering system has a rack which is toothed on two sides and cooperates with two pinions. At least one of the pinions can be axially translated in dependence on forces acting between the rack and that pinion. This axial translation controls a clutch arrangement so that a servomotor continuously rotating in one direction can in each case be nonpositively coupled to one of the pinions or uncoupled from both pinions.

A device and method for the equiaxial connection of multiple-part linkages includes a bush whose inside contour has a serration and whose outside contour is constructed as a dihedral profile. A flange of a coupling is slipped over the bush which has been fitted onto an end of a rod, this rod end being provided with a surface toothing. The inside contour of the flange has a dihedral profile corresponding to the bush. The device allows automated connection of steering linkages in vehicle assembly.

A servo control for power-assisted steering for motor vehicles having two coaxial shaft parts that are positively coupled to each other, but with play. The shaft parts are coupled such that limited relative rotations between these shaft parts are possible against the resistance of a pretensioned spring arranged in between. These relative rotations cause a pivoting stroke of a lever arranged between the shaft parts, this lever thereby actuating the control spool of a servo valve.
