Abstract

A wheel module for a motor vehicle, the wheel module including a wheel carrier, a wheel hub, a wheel bearing separate from the wheel hub that supports the wheel hub on the wheel carrier, and a drive shaft for driving the wheel hub. The wheel hub having end face toothing engaging a mating toothing on the drive shaft. A spacer element is arranged axially between the wheel bearing and the drive shaft wherein the spacer element adjoins the end face toothing and/or the mating toothing radially on the outside.

First claim

What is claimed is:

1 . A wheel module comprising:
a wheel hub; a wheel bearing separate from the wheel hub; a drive shaft wherein said wheel hub has an end face toothing engaging a mating toothing on said drive shaft; and a spacer element arranged axially between said wheel bearing and said drive shaft such that said spacer element spans a junction of said end face toothing and said mating toothing.

2 . The wheel module of claim 1 wherein said end face toothing is arranged around a central bore in said wheel hub.

3 . The wheel module of claim 1 wherein said wheel bearing is mounted on said wheel hub in an axial direction and rests against a radially outward-extending shoulder on said wheel hub.

4 . The wheel module of claim 1 wherein said wheel bearing is inserted into said wheel carrier in an axial direction and is secured between a radially inward-extending shoulder on said wheel carrier and a retaining ring inserted into said wheel carrier.

5 . The wheel module of claim 1 wherein said spacer element has a sealing portion extending radially outward into the region of said wheel carrier.

6 . The wheel module of claim 1 wherein said wheel hub is clamped against said drive shaft by a screw, said screw passing through a central bore in the wheel hub.

7 . The wheel module of claim 6 wherein said screw engages in an internal thread on said drive shaft.

8 . The wheel module of claim 1 wherein said spacer element adjoins the end face toothing or mating toothing radially on the outside.

9 . The wheel module of claim 1 wherein said spacer element includes a contact flange and a sealing portion, said sealing portion extending radially outward from said contact flange.

10 . A wheel module comprising:
a wheel hub; a wheel bearing separate from the wheel hub; a drive shaft wherein said wheel hub has an end face toothing engaging a mating toothing on said drive shaft; and a spacer element having a contact flange and a sealing portion, said contact flange extending between and contacting said bearing element and said drive shaft wherein said contact portion spans a junction of said end face toothing and said mating toothing and said sealing portion extending radially outward from said contact flange.

11 . The wheel module of claim 10 wherein said end face toothing is arranged around a central bore in said wheel hub.

12 . The wheel module of claim 11 wherein said wheel bearing is mounted on said wheel hub in an axial direction and rests against a radially outward-extending shoulder on said wheel hub.

13 . The wheel module of claim 12 wherein said wheel bearing is inserted into said wheel carrier in an axial direction and is secured between a radially inward-extending shoulder on said wheel carrier and a retaining ring inserted into said wheel carrier.

14 . The wheel module of claim 13 wherein said wheel hub is clamped against said drive shaft by a screw, said screw passing through a central bore in the wheel hub.

15 . The wheel module of claim 14 wherein said screw engages in an internal thread on said drive shaft.
