Embodiment Construction

[0017] exist figure 1 The suspension strut bearing 1 shown in , essentially comprises a housing lower part 2 and a housing upper part 3 , which together form a bearing housing in which an axial rolling bearing 4 is accommodated. Housing lower part 2 and housing upper part 3 are connected to one another via a snap connection, the two housing parts forming a labyrinth seal 5 which prevents dirt, sand or moisture from penetrating into axial rolling bearing 4 .

[0018] In the region of the parting gap between the housing lower part 2 and the housing upper part 3, the housing parts 2, 3 each have a radial projection 6, 7 on which a sealing ring 8 is held. between.

[0019] The sealing ring 8 has a rectangular cross section and is arranged displaceably between the projections 6 , 7 . When the suspension strut is cleaned with a high-pressure water jet, the sealing ring 8 acts as a splash guard and prevents moisture or dirt from reaching the area of ​​the labyrinth seal 5 or from e...

Abstract

The present invention relates to a suspension slide column support saddle which includes an axial sliding bearing or an axial rolling bearing, and the axial sliding bearing or axial rolling bearing is accommodated between a casing lower component and a casing upper component of a bearing casing; and at least one sealing element which seals the separation seam between the casing lower component and the casing upper component, wherein the sealing element is provided with at least one sealing ring (8, 13) which seals the separation seam between the inner circumference edge and the outer circumference edge of the bearing casing.

Description

technical field [0001] The invention relates to a suspension strut bearing. Background technique [0002] A suspension strut for a motor vehicle comprises a telescopic tube shock absorber and a helical spring with a large diameter, which is supported by a disc-shaped mount on the shock absorber and on the body mount of the motor vehicle. When the car turns, the suspension struts rotate around the piston rods of the shock absorbers. In order to reduce the resistance during steering, an axial plain bearing or an axial rolling bearing is arranged in the region of the bearing of the coil spring, said bearing mainly absorbing the axial weight and shock loads. [0003] A suspension strut bearing is known from DE 100 42 677 A1, in which an axial rolling bearing is accommodated between an upper housing part and a lower housing part, which are connected to each other by snap connections. To prevent the ingress of dirt and the egress of lubricant, a labyrinth seal is provided. [0...
