Rolling-element bearing unit for wheel bearing assembly
First Claim
1. A rolling-element bearing unit for a wheel bearing assembly of a vehicle, comprising:
- a rolling-element bearing including a bearing outer ring, a bearing inner ring, a bearing interior between the bearing outer ring and the bearing inner ring and a plurality of rolling elements disposed in the bearing interior, the bearing inner ring having an inner ring surface facing the bearing interior and a first and a second axial end surface,a first seal assembly comprising a retainer fixed on the bearing outer ring and supporting a seal element configured to slidingly seal directly against the bearing inner ring surface,wherein, the retainer is an angle bracket having an axially extending annular leg and a radially inwardly extending annular flange, the radially inwardly extending annular flange projecting radially inwardly beyond the bearing inner ring surface, wherein the seal element does not contact the radially inwardly extending annular flange of the retainer,wherein the bearing inner ring includes a step on the first axial end surface, wherein the step, when viewed in cross section, has a radially extending step surface and an axially extending step surface, and wherein the radially inwardly extending flange extends radially along the radially extending step surface, andwherein the step is formed by a slip sleeve pushed onto the bearing inner ring and wherein the radially extending step surface is formed by the bearing inner ring surface and the axially extending step surface is formed by an end surface of the slip sleeve.

Abstract
A rolling-element bearing unit for a wheel bearing assembly of a vehicle includes a rolling-element bearing with an outer ring, a an inner ring, a bearing interior between the outer ring and the inner ring and a plurality of rolling elements in the bearing interior. The inner ring has an inner ring surface facing the bearing interior and a first and a second axial end surface. A first seal assembly includes a retainer fixed on the bearing outer ring and a seal element configured to slidingly seal against the bearing inner ring surface or against a slip sleeve carried by the bearing inner ring. The retainer is an angle bracket having an axially extending annular leg and a radially inwardly extending annular flange, and radially inwardly extending flange projects radially inwardly beyond the bearing inner ring surface, for example, over a step in the first axial end surface.
