Steering spindle for a motor vehicle and method for the production thereof

摘要

The invention relates to a steering spindle for a motor vehicle with a plug-in connection which has a splined-shaft profile which extends axially and is arranged at one end on a shaft, and a receiving tube which receives the splined-shaft profile and is provided along its internal circumference with corresponding internal splines. The steering spindle furthermore has, in the region of the plug-in connection, a plastic layer which extends axially at least in some areas and fills clearances between the internal wall of the receiving tube and the splined-shaft profile. The splines, arranged in the region of the receiving tube, of one part are designed such that they are continuous in the axial direction and in the circumferential direction are of a smaller size than the grooves of the other part. The splines of one part are provided with the plastic layer of rubbery-elastic plastic, which layer bridges this reduced-size portion, this plastic layer having an axial extent which is larger than the amount of the maximum relative movement between the shaft and receiving tube.
