Abstract

A wheel hub, especially a wheel hub for commercial vehicles, for receiving a brake disk, in which a neck section which is formed on the wheel flange for receiving the brake disk, the neck section being provided with a surface structure, preferably ribs, which increases the amount of heat given off to the environment. There may also be provided ducts between the ribs to permit cooling air to pass between the wheel flange and the brake disk to further increase the amount of heat given off to the environment.

Claims

1. Wheel hub for receiving a brake disk, having a hub body which is molded to a wheel flange and has a neck section designed for receiving the brake disk, the neck section, in an axial area adjoining an area for the placing of the brake disk, being provided with ribs which extend essentially in an axial direction in an outer circumference of the neck section and ducts formed between the ribs,

wherein the outer circumference of the neck section has cams at an end of the neck axially most remote from the wheel flange, the cams each having a collar for axially securing the brake disk at said most remote end of the neck, each cam being molded to two of the ribs, the ribs extend over the area between the cams and the wheel flange, and a portion of the ducts starts between the cams of the wheel hub.

2. Wheel hub according to claim 1, wherein the ribs extend in an inclined manner with respect to an axis of rotation of the hub at the outer circumference of the neck section.

3. Wheel hub according to claim 1, wherein the ribs and the ducts extend to a wheel flange molded to the neck section.

4. Wheel hub according to claim 1, wherein the ducts between the ribs lead at least partially into openings which penetrate the wheel flange.

5. Wheel hub according to claim 4, wherein all ducts lead into the openings.

6. Wheel hub according to claim 1, wherein the wheel hub comprises a light metal.

7. Wheel hub according to claim 1, wherein the wheel hub comprises cast iron or steel.

8. Wheel hub according to claim 1, wherein the neck section is adapted to be placed onto a wheel bearing arrangement designed for accommodating an axle.

9. A wheel hub for receiving a brake disk, comprising:

a hub body, the hub body including a wheel flange and a neck section adapted to receive the brake disk, wherein

a plurality of axial ribs are disposed on an outside circumferential surface of the neck section parallel to an axis of rotation of the hub body,

a plurality of cams are disposed radially about an end of the neck section opposite a wheel flange end, each cam formed with at least two of the ribs and having a collar adapted to arrest axial motion of the brake disk toward the wheel flange,

each of the ribs which is formed with a cam extends between its cam and the wheel flange, and

a plurality of ducts penetrate the wheel flange, each duct being aligned and communicating with a corresponding gap between two of the plurality of ribs.

10. The wheel hub of claim 9, wherein a height of the ribs above the outer circumference of the neck section varies between the brake disk end and the wheel flange end.

11. The wheel hub of claim 9, wherein the wheel flange is integrally formed with the neck section.

12. The wheel hub of claim 9, wherein the hub body is formed from a light metal.

13. The wheel hub of claim 9, wherein the hub body is formed from one of cast iron and steel.

14. The wheel hub of claim 9, wherein the neck section is adapted to receive a wheel bearing arrangement for mounting on an axle.
