Abstract (en)
[origin: WO2011134688A1] The invention relates to a bearing bush assembly (100) for a telescopic steering shaft comprising an outer tube (120) and an inner tube (110) wherein, for the axially movable and sealed connection of the inner tube (110) to the outer tube (120), the bearing bush assembly (100) has a bearing bush (10) bearing on the inner tube (110) and composed of an inelastic plastic, and a sealing element (30) injection-molded thereon and consisting of an elastic plastic. The bearing bush (10) is enclosed by an elastic bush, in particular a rubber bush (20), which in turn is enclosed by an end section of the outer tube (120), which means that a considerable damping action in the radial and/or axial direction achieved, so that a considerable reduction in vibration and noise is established in the steering system. In order to further improve the radial damping, the rubber bush (20) is provided on the outer periphery thereof with web-like elements, in particular convex webs (24) extending outward. In addition, to improve the axial damping, at least one sealing lip (27) extending in the axial direction can be provided on the rubber bush (20).
