Abstract

A motor vehicle wheel with a radially inner hub and a radially outer rim. The rim has an axially inner internal rim flange, which faces the motor vehicle in the installation position, on a first side, an axially outer external rim flange, which faces away from the motor vehicle in the installation position, on a second side, and a rim base, which is positioned between the two flanges. At least one circular hollow chamber which runs in the circumferential direction is formed between the rim and the hub in the radial direction in the region of the second side.

First claim

1 . A motor vehicle wheel, with a radially inner hub and a radially outer rim, wherein the rim has an axially inner internal rim flange on a first side, which faces the motor vehicle in the installed position, an axially outer external rim flange on a second side, which faces away from the motor vehicle in the installed position, and a rim base which is positioned between said two rim flanges, wherein at least one hollow chamber encircling in a circumferential direction is formed in a radial direction between the rim and the hub in the region of the second side.

2 . The motor vehicle wheel as claimed in claim 1 , wherein the wheel has a single hollow chamber which encircles in the circumferential direction and directly adjoins the hub in the radial direction, wherein intermediate elements having apertures positioned therebetween in the circumferential direction are formed between the hollow chamber and the rim.

3 . The motor vehicle wheel as claimed in claim 1 , wherein the wheel has a single hollow chamber which encircles in the circumferential direction and directly adjoins the rim in the radial direction, wherein intermediate elements having apertures positioned therebetween in the circumferential direction are formed between the hollow chamber and the hub.

4 . The motor vehicle wheel as claimed in claim 1 , wherein the wheel has a single hollow chamber which encircles in the circumferential direction and extends between the rim and the hub.

5 . The motor vehicle wheel as claimed in claim 1 , wherein the wheel includes a first hollow chamber which directly adjoins the rim in the radial direction, and a second hollow chamber which directly adjoins the hub in the radial direction.

6 . The motor vehicle wheel as claimed in claim 5 , wherein intermediate elements having apertures positioned therebetween in the circumferential direction are formed between the first hollow chamber and the second hollow chamber.

7 . The motor vehicle wheel as claimed in claim 2 , wherein the intermediate elements are spokes extending substantially in the radial direction.

8 . The motor vehicle wheel as claimed in claim 2 , wherein the intermediate elements are struts extending substantially in the axial direction.

9 . The motor vehicle wheel as claimed in claim 1 , wherein the or each hollow chamber is bounded axially by in each case two frustoconically contoured profiles which are spaced apart in the axial direction, and radially by the hub and/or the rim.

10 . The motor vehicle wheel as claimed in claim 9 , wherein a first frustoconically contoured profile is an integral part of the hub and/or of the rim.

11 . The motor vehicle wheel as claimed in claim 10 , wherein a second frustoconically contoured profile is welded to the first frustoconically contoured profile and to the hub and/or to the rim.

12 . The motor vehicle wheel as claimed in claim 1 , wherein the or each hollow chamber encircling in the circumferential direction is subdivided in the circumferential direction into partial chambers.
