Abstract

A wheel carrier device for a vehicle, with at least one wheel carrier which has at least one bearing point at which at least one wheel bearing is to be mounted for rotatably mounting a wheel hub, wherein the wheel carrier is at least partially surrounded on the outer circumference by at least one thermal insulation element.

First claim

The invention claimed is:

1. A wheel carrier device for a vehicle, comprising:
at least one wheel carrier which has at least one bearing point at which at least one wheel bearing is to be mounted for rotatably mounting a wheel hub,
wherein the wheel carrier is at least partially surrounded on the outer circumference by at least one thermal insulation element.

2. The wheel carrier device according to claim 1 , wherein the wheel carrier is mostly surrounded on the outer circumference by the thermal insulation element.

3. The wheel carrier device according to claim 1 , wherein the thermal insulation element overlaps the bearing point at least partially.

4. The wheel carrier device according to claim 1 , wherein the thermal insulation element surrounds the bearing point at least partially on at least three different sides of the bearing point.

5. The wheel carrier device according to claim 1 , wherein the thermal insulation element has direct contact with an outer circumferential jacket surface of the wheel carrier.

6. The wheel carrier device according to claim 1 , wherein the wheel carrier is formed from a first material, and the thermal insulation element is formed from a second material, which is different from the first material.

7. The wheel carrier device according to claim 1 , wherein the wheel carrier device has the wheel bearing which is arranged at the bearing point.

8. The wheel carrier device according to claim 7 , wherein the wheel bearing is at least partially surrounded on the outer circumference by at least one further thermal insulation element arranged between the wheel bearing and the wheel carrier.

9. The wheel carrier device according to claim 2 , wherein the thermal insulation element overlaps the bearing point at least partially.

10. The wheel carrier device according to claim 2 , wherein the thermal insulation element surrounds the bearing point at least partially on at least three different sides of the bearing point.

11. The wheel carrier device according to claim 3 , wherein the thermal insulation element surrounds the bearing point at least partially on at least three different sides of the bearing point.

12. The wheel carrier device according to claim 2 , wherein the thermal insulation element has direct contact with an outer circumferential jacket surface of the wheel carrier.

13. The wheel carrier device according to claim 3 , wherein the thermal insulation element has direct contact with an outer circumferential jacket surface of the wheel carrier.

14. The wheel carrier device according to claim 4 , wherein the thermal insulation element has direct contact with an outer circumferential jacket surface of the wheel carrier.

15. The wheel carrier device according to claim 2 , wherein the wheel carrier is formed from a first material, and the thermal insulation element is formed from a second material, which is different from the first material.

16. The wheel carrier device according to claim 3 , wherein the wheel carrier is formed from a first material, and the thermal insulation element is formed from a second material, which is different from the first material.

17. The wheel carrier device according to claim 4 , wherein the wheel carrier is formed from a first material, and the thermal insulation element is formed from a second material, which is different from the first material.

18. The wheel carrier device according to claim 5 , wherein the wheel carrier is formed from a first material, and the thermal insulation element is formed from a second material, which is different from the first material.

19. A vehicle, comprising:
at least one wheel carrier device having at least one wheel carrier which has at least one bearing point at which at least one wheel bearing is to be mounted for rotatably mounting a wheel hub, wherein the wheel carrier is at least partially surrounded on the outer circumference by at least one thermal insulation element; and
at least one bearing device with at least one wheel bearing for rotatably mounting a wheel hub on a wheel carrier of the vehicle, wherein the wheel bearing is at least partially surrounded on the outer circumference by at least one thermal insulation element.
