Abstract

A wheel hub includes an outer collar region, as seen in the radial direction, and an inner core region, as seen in the radial direction, wherein, as seen in the axial direction, the inner core region is thicker than the outer collar region, and wherein, in the inner core region, the wheel hub has a substantially axially running primary recess for the connection of a brake disk.

First claim

The invention claimed is:

1. A wheel hub, comprising:
an outer collar region, as seen in a radial direction; and
an inner core region, as seen in the radial direction;
wherein the inner core region has a greater extent in an axial direction than the outer collar region;
wherein, in the inner core region, the wheel hub has a substantially axially running primary recess for the connection of a brake disk;
wherein a ratio between a radial distance between an axis of rotation and the primary recess and a radius of the wheel hub is between 0.6 and 0.3;
wherein the primary recess completely penetrates the wheel hub; and
wherein the primary recess opens toward one side in a brake disk contact surface and wherein the brake disk contact surface is interrupted, as seen in a revolving direction.

2. The wheel hub as claimed in claim 1 , wherein the core region comprises substantially radially running rib elements.

3. The wheel hub as claimed in claim 2 , wherein the rib elements connect the core region to the collar region.

4. The wheel hub as claimed in claim 2 , wherein each rib element has only one primary recess.

5. The wheel hub as claimed in claim 1 , wherein a ratio between an extent of the primary recess, as measured in the axial direction, to an overall extent of the wheel hub in the axial direction is between 0.5 and 0.98.

6. The wheel hub as claimed in claim 5 , wherein the ratio between the extent of the primary recess to the overall extent of the wheel hub is between 0.75 and 0.95.

7. The wheel hub as claimed in claim 6 , wherein the ratio between the extent of the primary recess to the overall extent of the wheel hub is between 0.8 and 0.93.

8. The wheel hub as claimed in claim 1 , wherein the ratio is between 0.55 and 0.35.

9. The wheel hub as claimed in claim 8 , wherein the ratio is between 0.4 and 0.5.

10. The wheel hub as claimed in claim 1 , wherein a clear region is arranged between two rib elements, as seen in a revolving direction.

11. The wheel hub as claimed in claim 10 , wherein an area of the rib elements measured in the revolving direction is 0.3 to 0.5 times as large as an area of the clear region.

12. The wheel hub as claimed in claim 1 , wherein the outer collar region has a secondary recess, and wherein the primary recess extends further in the axial direction than the secondary recess.

13. The wheel hub as claimed in claim 1 , wherein the primary recess is arranged offset in a revolving direction with respect to a secondary recesses.

14. The wheel hub as claimed in claim 1 , wherein the primary recess, as seen in the radial direction, extends over the entire length of a rib element, or wherein the primary recess is at least partially formed by a sleeve-shaped partial region which protrudes from a rib element in the axial direction.

15. The wheel hub as claimed in claim 1 , wherein the primary recess opens toward one side in a brake disk contact surface, and wherein the brake disk contact surface is continuous, as seen in a revolving direction.

16. A system comprising a brake disk and a wheel hub as claimed in claim 1 , wherein the brake disk is connectable to a brake disk contact surface, by a fastener guided through the primary recess.

17. A method for mounting a brake disk on a wheel hub, as claimed in claim 1 , comprising:
providing a wheel hub as claimed in claim 1 ;
introducing a fastener into the primary recess; and
connecting the brake disk to the wheel hub by the fastening assembly.
