Bearing element for rack-and-pinion steering gear and the hydraulically assisted rack-and-pinion steering gear with the bearing element

摘要

The present invention relates to a bearing element (10; 10 '') for longitudinally displaceable mounting of a toothed rack (30) of a tooth rods steering gear inside of a steering housing (40), comprising an annular basic body (11) with a passage opening (15) for receiving the toothed rack (30), whereby in the area of the passage opening (15) bearing means (12) for longitudinally displaceable mounting of the toothed rack (30) with respect to the base body (11) are provided. The invention is characterised in that on the outside of the base body (11) of at least one damping element (20; 20 '') is mounted, wherein the outer contour of this damping element (20; 20'') in such a way on the inner contour of a steering housing (40) is adapted to that the bearing element (10; 10 '') in the case of introduction into the steering housing (40) in contact with the inside of the steering housing (40) has, without the base body (11) of the bearing element (10; 10'') is in contact with the steering housing (40). The bearing element (10; 10 '') further comprises a sealing element (13), the so formed and on the base body (11) is mounted a way that, during introduction of the toothed rack (30) in the bearing means (12) a sealing contact with the toothed rack (30) has.The present invention also relates to a hydraulically assisted rack-and-pinion steering gear with such a bearing element (10; 10'').
