Problems solved by technology

[0006] However, this creates the following problem: the commonly used cartridge seals are no longer usable and the cartridge seals have to be adapted to the specific environment and preload
This is on the one hand expensive and on the other hand requires very time-consuming installation

Embodiment Construction

[0059] exist figure 1 In , a bearing combination unit 1 is depicted comprising two tapered roller bearings 2 and 3 . Each of the two tapered roller bearings 2, 3 has an inner ring 4 or 5 but shares an outer ring 6, or as figure 2 As depicted, each tapered roller bearing has its own outer ring 6 , 7 . The rolling elements 8 or 9 are arranged between the bearing rings. Such a bearing combination unit may especially be found in a wheel bearing unit, wherein the bearing combination unit is mounted to the hub R of the wheel.

[0060] The depicted bearing combination units are embodied in a back-to-back configuration. Ribs 10 and 11 on the inner rings 4, 5 limit the axial mobility of the tapered rollers 8, 9.

[0061] Here, the ribs 10 , 11 are designed as sleeve-shaped components (rib sleeves), which are pushed onto the bearing rings 4 , 5 . Although the sleeve-shaped member 11 of the inner ring 5 is fixed on the inner ring 5 as a fixed rib, this does not apply to the sleeve-...

Abstract

In the following a bearing assembly, in particular a wheel bearing assembly for a vehicle, with at least one rolling-element bearing, in particular with two tapered roller bearings, is presented, wherein the at least one rolling-element bearing includes a bearing outer ring and a bearing inner ring that define a bearing interior between them in which rolling elements are disposed. Furthermore, the bearing assembly includes a seal assembly for sealing the bearing assembly, wherein the seal assembly includes a carrier element that is connectable, for example, via an axially extending ring arm, to one of the bearing rings of the bearing assembly such that they rotate together, and includes a radially extending annular flange, wherein the radially extending flange carries a radially encircling seal with at least one seal lip. The seal lip in turn extends toward the other bearing ring and sealingly abuts on a sleeve-shaped element that is connectable to the other bearing ring of the bearing assembly such that they rotate together, and the sleeve-shaped element is configured to form a flange of an axial stopper of the rolling elements.

Description

technical field [0001] The invention relates to a bearing assembly for a wheel bearing assembly of a vehicle with a sealed assembly. Background technique [0002] Bearing assemblies of the type described above for wheel bearing assemblies are usually embodied as tapered roller bearing assemblies. Here, two mating tapered roller bearings are axially preloaded against one another and are accommodated on or in the hub. Furthermore, a sealing combination is provided to seal the bearing combination against the ingress of dirt and / or water and / or against the escape of lubricant. This sealing combination is usually embodied as a cassette seal and is applied as a complete component to the bearing combination, in particular to the bearing ring. [0003] Furthermore, setting the preload in tapered roller bearings is a relatively complex and imprecise process in which attempts are made to displace the two inner rings of a tapered roller bearing unit axially towards each other (in a b...
