Abstract

A wheel hub arrangement for a motor vehicle, provided with a hub which is rotatably mounted by a wheel bearing for the attachment of a wheel. A shaft, which is formed separately from the wheel hub, is non-rotatably coupled to the wheel hub. At the same time a first receiving section of a sealing receptacle is formed in the wheel hub in which is arranged a shaft, in which a sealing device is arranged which engages a second receiving section of the sealing receptacle formed in the axial direction with respect to an axis of rotation of the wheel hub, adjacent to the first receiving section.

First claim

The invention claimed is:

1. A wheel hub arrangement for a motor vehicle, comprising: a wheel hub, which is rotatably mounted by a wheel bearing, for the attachment of a wheel, wherein a shaft, formed separately from the wheel hub, is non-rotatably coupled to the wheel hub, wherein a first receiving section of a sealing receptacle is formed in the wheel hub, in which is arranged a sealing device, the sealing device engaging a second receiving section of the sealing receptacle, the second receiving section formed in the shaft, adjacent to the first receiving section of the sealing receptacle and adjoining the first receiving section in the axial direction with respect to the rotational axis of the wheel hub wherein the sealing device is sealingly arranged on an inner circumferential surface of the wheel hub and on an inner circumferential surface of the shaft.

2. The wheel hub arrangement according to claim 1 , wherein the shaft is provided, on a side facing the wheel hub, with a shaft pin engaged in the wheel hub, the shaft pin connected to a joint hub of a synchronous joint or a cardan joint.

3. The wheel hub arrangement according to claim 1 , wherein the first receiving section completely engages the wheel hub in the axial direction.

4. The wheel hub arrangement according to claim 2 , wherein the shaft pin is designed as a hollow pin and an inner circumferential surface is present in the shaft pin.

5. The wheel hub arrangement according to claim 1 , wherein the sealing device projects beyond the wheel hub on a side facing away from the shaft and is provided therein with radial projections for the formation of a hub cap, which projects in a radial direction over the first receiving section.

6. The wheel hub arrangement according to claim 1 , wherein the shaft is fixed in the axial direction by a fixing means with respect to the wheel hub, which is different from the sealing device.

7. The wheel hub arrangement according to claim 1 , wherein the second receiving section completely engages the shaft in the axial direction.
