Abstract

A wheel bearing arrangement of a vehicle axle is disclosed. The wheel bearing arrangement includes a wheel bearing, which contains at least two rolling element rows, for supporting a wheel hub which can be driven by a drive element. The rolling elements of the wheel bearing are guided in races of a stationary outer ring, the rotating wheel hub, and a separate inner ring which is allocated to the wheel hub. In the assembled state, the wheel hub of the wheel bearing arrangement and the drive element are operatively connected via gearing. The inner ring has a radially stepped inner contour, the inner contour having two diameters which differ from one another, and are received in a complementarily designed receiving area of the wheel hub. The position of the inner ring is fixed on the end face by a rolling riveted collar of the wheel hub.

First claim

The invention claimed is:

1. A wheel bearing arrangement of a vehicle axle, comprising a wheel bearing that includes at least two rolling element rows having rolling elements for supporting a wheel hub that is driven by a drive element or a wheel hub that is not driven, the rolling elements of the wheel bearing are guided in a radially outer raceway of a stationary outer ring and a radially inner raceway of a separate inner ring allocated to the wheel hub, and the drive element is in an active connection with the wheel hub by gearing, the inner ring has a radially stepped inner contour that has two inner diameters (D 1 , D 2 ) that deviate from each other and fit in a complementarily shaped receptacle of the wheel hub and is further fixed in position on an end side by a rolling riveted collar of the wheel hub, a radially oriented wall of the inner ring extends radially outwardly and radially overlaps with the radially outer raceway, and the inner ring is installed in an installed state with a smallest inner diameter (D 2 ) oriented toward the rolling-riveted collar.

2. The wheel bearing arrangement according to claim 1 , wherein the radially oriented wall of the inner ring is guided up to an annular gap on an inner contour of the outer ring.

3. The wheel bearing arrangement according to claim 1 , wherein the radially inner raceway defines a curved surface for supporting the rolling elements that extends continuously to the radially oriented wall of the inner ring, and the curved surface radially overlaps with the radially outer raceway.

4. The wheel bearing arrangement according to claim 1 , wherein an encoder is directly attached to both a radially outer end surface and an axial end surface of the radially oriented wall.

5. A wheel bearing arrangement of a vehicle axle, comprising a wheel bearing that includes at least two rolling element rows having rolling elements for supporting a wheel hub that is driven by a drive element or a wheel hub that is not driven, the rolling elements of the wheel bearing are guided in a radially outer raceway of a stationary outer ring and a radially inner raceway of a separate inner ring allocated to the wheel hub, and the drive element is in an active connection with the wheel hub by gearing, the inner ring has a radially stepped inner contour that has two inner diameters (D 1 , D 2 ) that deviate from each other and fit in a complementarily shaped receptacle of the wheel hub and is further fixed in position on an end side by a rolling riveted collar of the wheel hub, a radially oriented wall of the inner ring extends radially outwardly and radially overlaps with the radially outer raceway, further comprising a disk-shaped cover element that overlaps or covers the rolling-riveted collar of the wheel hub is mounted on the outer ring.

6. The wheel bearing arrangement according to claim 5 , wherein the inner ring is installed in an installed state with a smallest inner diameter (D 2 ) oriented toward the rolling-riveted collar.

7. The wheel bearing arrangement according to claim 5 , wherein the cover element has a receptacle for a sensor that interacts with an encoder that is arranged on the inner ring, which are parts of a device for measuring rotational movements of the wheel bearing.

8. The wheel bearing arrangement according to claim 5 , wherein the radially oriented wall of the inner ring is guided up to an annular gap on an inner contour of the outer ring.

9. The wheel bearing arrangement according to claim 5 , wherein the radially inner raceway defines a curved surface for supporting the rolling elements that extends continuously to the radially oriented wall of the inner ring, and the curved surface radially overlaps with the radially outer raceway.

10. The wheel bearing arrangement according to claim 5 , wherein an encoder is directly attached to both a radially outer end surface and an axial end surface of the radially oriented wall.

11. A wheel bearing arrangement of a vehicle axle, comprising a wheel bearing that includes at least two rolling element rows having rolling elements for supporting a wheel hub that is driven by a drive element or a wheel hub that is not driven, the rolling elements of the wheel bearing are guided in a radially outer raceway of a stationary outer ring and a radially inner raceway of a separate inner ring allocated to the wheel hub, and the drive element is in an active connection with the wheel hub by gearing, the inner ring has a radially stepped inner contour that has two inner diameters (D 1 , D 2 ) that deviate from each other and fit in a complementarily shaped receptacle of the wheel hub and is further fixed in position on an end side by a rolling riveted collar of the wheel hub, a radially oriented wall of the inner ring extends radially outwardly and radially overlaps with the radially outer raceway, wherein the wheel hub is connected to the drive element by positive-fit spur gearing or internal gearing formed on an axial end face of the wheel hub.

12. The wheel bearing arrangement according to claim 11 , wherein the inner ring is installed in an installed state with a smallest inner diameter (D 2 ) oriented toward the rolling-riveted collar.

13. The wheel bearing arrangement according to claim 11 , wherein the radially oriented wall of the inner ring is guided up to an annular gap on an inner contour of the outer ring.

14. The wheel bearing arrangement according to claim 11 , wherein the radially inner raceway defines a curved surface for supporting the rolling elements that extends continuously to the radially oriented wall of the inner ring, and the curved surface radially overlaps with the radially outer raceway.

15. The wheel bearing arrangement according to claim 11 , wherein an encoder is directly attached to both a radially outer end surface and an axial end surface of the radially oriented wall.
