Steering column bearing for supporting a steering column of a motor vehicle

Abstract

A steering bearing for bearing a steering column of a motor vehicle, including an inner ring and an outer ring having respective raceways on which balls roll, the outer ring being enclosed by a sleeve in which a spring ring is arranged. The spring ring tensions the balls against the respective raceways and the balls roll on said spring ring.

Description

Technical field The invention relates to a steering column bearing for supporting a steering column of a motor vehicle. The steering column bearing has an inner ring and an outer ring with respective raceways, and balls are rolled on the raceways. Background technique It is well known that steering column bearings are used to support the steering column of the steering equipment of a motor vehicle. The steering column bearing is used to support the steering mandrel connecting the steering wheel and the steering transmission without clearance. Here, the steering column bearing should have high rigidity on the one hand, but should also have as low friction as possible on the other hand, in order to be able to realize the light operation of the steering device. The steering column bearing must also be able to effectively dampen noise and vibration, just as it should be as insensitive as possible to common shaft and housing tolerances, and ensure high-pressure tightness or retenti...
