Abstract

A wheel bearing arrangement for a motor vehicle, having a wheel hub and a wheel bearing for rotatably mounting the wheel hub on a wheel carrier. The wheel bearing has an outer ring and an inner ring. A wheel flange extends from the wheel hub in a radial direction and has a brake disc receptacle which is open in the direction facing away from the outer ring and is formed by a recess in the wheel flange and has a brake disc bearing face for a brake disc. A seal-receptacle space is formed in the wheel flange on its side facing the outer ring in an axial direction, in which seal-receptacle space there is a wheel bearing seal. A rim-centering seat element extends from the wheel hub and runs in the direction opposite the brake disc bearing face with respect to the brake disc receptacle.

First claim

The invention claimed is:

1. A wheel bearing arrangement for a motor vehicle, comprising: a wheel hub and a wheel bearing for rotatably mounting the wheel hub on a wheel carrier, wherein the wheel bearing has an outer ring and an inner ring which can rotate with respect to the outer ring about a rotational axis, wherein the inner ring is connected to the wheel hub, wherein a wheel flange extends from the wheel hub in a radial direction and has a brake disc receptacle which, when viewed in the axial direction, is open in the direction facing away from the outer ring and is formed, when viewed in a longitudinal section, by a recess in the wheel flange and has a brake disc bearing face for a brake disc, wherein the wheel flange has a wheel flange end face on a side facing the outer ring in an axial direction, wherein a wheel bolt receptacle is present between the brake disc bearing face and the wheel flange end face, wherein the wheel flange end face is flush with an end of the wheel bolt receptacle in the axial direction, wherein a seal-receptacle space is formed in the wheel flange on the side facing the outer ring in the axial direction, wherein a rim-centering seat element extends from the wheel hub and runs in the direction opposite the brake disc bearing face with respect to the brake disc receptacle, wherein the wheel flange end face overlaps, in the axial direction, with an outer ring end of the outer ring facing the wheel flange.

2. The wheel bearing arrangement as claimed in claim 1 , wherein the rim-centering seat element has a larger internal diameter than the wheel hub.

3. A wheel bearing arrangement for a motor vehicle, comprising: a wheel hub and a wheel bearing for rotatably mounting the wheel hub on a wheel carrier, wherein the wheel bearing has an outer ring and an inner ring which can rotate with respect to the outer ring about a rotational axis, wherein the inner ring is connected to the wheel hub, wherein a wheel flange extends from the wheel hub in a radial direction and has a brake disc receptacle which, when viewed in the axial direction, is open in the direction facing away from the outer ring and is formed, when viewed in a longitudinal section, by a recess in the wheel flange and has a brake disc bearing face for a brake disc, wherein a seal-receptacle space is formed in the wheel flange on a side facing the outer ring in an axial direction, wherein a rim-centering seat element extends from the wheel hub and runs in the direction opposite the brake disc bearing face with respect to the brake disc receptacle, wherein the outer ring of the wheel bearing terminates flush with a wheel flange end face of the wheel flange facing the outer ring.

4. The wheel bearing arrangement as claimed in claim 3 , wherein the seal-receptacle space, when viewed in the longitudinal section, is arranged overlapping in the radial direction with an inclined face connecting a wheel bearing face to the brake disc bearing face to form the recess.

5. The wheel bearing arrangement as claimed in claim 4 , wherein the rim-centering seat element has a larger internal diameter than the wheel hub.

6. The wheel bearing arrangement as claimed in claim 3 , wherein the seal-receptacle space, when viewed in the longitudinal section, has a first seal-receptacle space region having a first seal-receptacle space width and a second seal-receptacle space region having a second seal-receptacle space width different from the first seal-receptacle space width, wherein the first seal-receptacle space region, when viewed in the radial direction, merges into the second seal-receptacle space region overlapping the outer ring.

7. The wheel bearing arrangement as claimed in claim 3 , wherein the rim-centering seat element has a larger internal diameter than the wheel hub.

8. A wheel bearing arrangement for a motor vehicle, comprising: a wheel hub and a wheel bearing for rotatably mounting the wheel hub on a wheel carrier, wherein the wheel bearing has an outer ring and an inner ring which can rotate with respect to the outer ring about a rotational axis, wherein the inner ring is connected to the wheel hub, wherein a wheel flange extends from the wheel hub in a radial direction and has a brake disc receptacle which, when viewed in the axial direction, is open in the direction facing away from the outer ring and is formed, when viewed in a longitudinal section, by a recess in the wheel flange and has a brake disc bearing face for a brake disc, wherein a seal-receptacle space is formed in the wheel flange on a side facing the outer ring in an axial direction, wherein a rim-centering seat element extends from the wheel hub and runs in the direction opposite the brake disc bearing face with respect to the brake disc receptacle, wherein the seal-receptacle space, when viewed in the longitudinal section, has a first seal-receptacle space region having a first seal-receptacle space width and a second seal-receptacle space region having a second seal-receptacle space width different from the first seal-receptacle space width, wherein the first seal-receptacle space region, when viewed in the radial direction, merges into the second seal-receptacle space region overlapping the outer ring.

9. The wheel bearing arrangement as claimed in claim 8 , wherein the seal-receptacle space width is greater than a brake disc receptacle width present in the axial direction between a wheel bearing face and the brake disc bearing face.

10. The wheel bearing arrangement as claimed in claim 9 , wherein the brake disc receptacle width of the brake disc receptacle is greater by a factor of at most 1.25 than a wheel bolt receptacle width present between the wheel flange end face and the brake disc bearing face of a wheel bolt receptacle formed in the wheel flange, or in that the brake disc receptacle width corresponds to the wheel bolt receptacle width or is less than the wheel bolt receptacle width.

11. The wheel bearing arrangement as claimed in claim 9 , wherein the rim-centering seat element has a larger internal diameter than the wheel hub.

12. The wheel bearing arrangement as claimed in claim 9 , a rim-centering seat formed by the rim-centering seat element has a rim-centering seat width, which is present, when viewed in the axial direction, between the wheel bearing face and a rim-centering end face facing away from the wheel bearing face and corresponds to at least the brake disc receptacle width and/or at most the wheel bolt receptacle width.

13. The wheel bearing arrangement as claimed in claim 10 , wherein the rim-centering seat element has a larger internal diameter than the wheel hub.

14. The wheel bearing arrangement as claimed in claim 8 , wherein the rim-centering seat element has a larger internal diameter than the wheel hub.
