Abstract

Wheel bearing units are disclosed. In one example, a wheel bearing unit includes an outer ring element and an inner ring element, between which there are arranged at least two rolling body rows. The inner ring element may have a radial flange which is fastenable to an axle body or to a wheel. The radial flange and/or the inner ring element may have at least one projection on a surface facing toward the outer ring element.

First claim

The invention claimed is:

1. A wheel bearing unit comprising:
an outer ring element and an inner ring element, between which there are arranged at least two rolling body rows;
wherein the inner ring element has a radial flange which is fastenable to an axle body or to a wheel;
wherein the radial flange and/or the inner ring element has at least one projection on a surface facing toward the outer ring element; and
wherein the at least one projection has a coating.

2. The wheel bearing unit as claimed in claim 1 , wherein the at least one projection on the surface is formed as a ring segment.

3. The wheel bearing unit as claimed in claim 1 , wherein the at least one projection is formed integrally on the radial flange and/or on the inner ring element.
