Abstract

Wheel hub and method for forming a wheel hub. Wheel hub includes a rim having a circumferential surface with axial ends, and one rim flange being arranged at each axial end of the circumferential surface. The rim includes a fiber-reinforced plastic as a main component and each of the rim flanges is releasably connectable to the rim.

First claim

What is claimed:

1. A wheel hub comprising:
a rim having a circumferential surface with axial ends;
one rim flange being arranged at each axial end of the circumferential surface, wherein the rim comprises a fiber-reinforced plastic as a main component and each of the rim flanges is releasably connectable to the rim; and
a locking element, wherein at least one of the rim flanges is structured to slide onto the circumferential surface axially from an outside and to be secured against a movement axially outwards by the locking element, and
wherein the locking element is structured and arranged to form a rotation protection between the rim and the rim flange.

2. The wheel hub according to claim 1 being an aircraft wheel hub.

3. The wheel hub according to claim 1 , wherein at least one of the rim flanges comprises a fiber-reinforced plastic as a main component.

4. The wheel hub according to claim 1 , further comprising a run protection layer arranged on at least one of the rim flanges.

5. The wheel hub according to claim 1 , wherein the locking element is engageable with the rim in a positive fit.

6. The wheel hub according to claim 5 , wherein the locking element is structured as a clamping ring to engage in a groove on the rim and the rim flange has a pressure face structured to act on the clamping ring and load the clamping ring with a force component acting into the groove.

7. The wheel hub according to claim 6 , further comprising a support arrangement for a wheel bearing being insertable into the rim.

8. The wheel hub according to claim 7 , wherein the support arrangement comprises a divided bearing shell.

9. The wheel hub according to claim 7 , wherein the support arrangement is wrapped in an inextensible layer.

10. The wheel hub according to claim 7 , wherein the support arrangement is non-rotatably retained in the rim by a positive fit.

11. The wheel hub according to claim 1 , further comprising a thermal radiation reflection layer, wherein the circumferential surface of the rim has an inner circumference that is at least partially provided with the thermal radiation reflection layer.

12. The wheel hub according to claim 11 , wherein the thermal radiation reflection layer is formed as a film that is adhered to the inner circumference.

13. The wheel hub according to claim 12 , wherein the film comprises an insulating layer.

14. The wheel hub according to claim 11 , wherein catches for a braking device protrude from the inner circumference and the thermal radiation reflection layer is arranged between the catches.

15. A method of forming a wheel hub that includes a rim having a circumferential surface having axial ends, the method comprising:
releasably connecting a rim flange onto at each axial end of the circumferential surface by axially sliding at least one of the rim flanges onto the circumferential surface from an outside; and securing the at least one rim flange against a movement axially outwards via a locking element,
wherein the rim comprises a fiber-reinforced plastic as a main component and wherein the locking element is structured and arranged to form a rotation protection between the rim and the rim flange.

16. The method according to claim 15 , further comprising at least partially applying a thermal radiation reflection layer onto an inner circumference of the circumferential surface.

17. The method according to claim 16 , wherein the thermal radiation reflection layer comprises a film with an insulating layer.
