Abstract

A vehicle wheel rim ( 1 ) having a wheel rim well ( 2 ) and having a wheel disk ( 16, 25, 37 ), wherein the wheel rim well ( 2 ) has a substantially axially extending region ( 3 ) and the wheel disk ( 16, 25, 37 ) has a substantially axially extending region ( 8, 9 ), wherein the wheel disk ( 16, 25, 37 ) and the wheel rim well ( 2 ) are connected to one another in the axially extending regions ( 3, 8, 9 ).

First claim

What is claimed:

1. A vehicle wheel rim ( 1 ) having a wheel rim well ( 2 ) and having a wheel disk ( 16 , 25 , 37 ) comprising a first shell element ( 4 , 5 , 20 , 21 ) and a second shell element ( 4 , 5 , 20 , 21 ), wherein the wheel rim well ( 2 ) has a substantially axially extending region ( 3 ) and the first and second shell elements ( 4 , 5 , 20 , 21 ) of the wheel disk ( 16 , 25 , 37 ) each have a substantially axially extending region ( 8 , 9 ), wherein the wheel disk ( 16 , 25 , 37 ) and the wheel rim well ( 2 ) are connected to one another in the axially extending regions ( 3 , 8 , 9 ), and wherein the axially extending regions ( 3 , 8 , 9 ) generate a planar connecting surface between the wheel disk ( 16 ) and the wheel rim well ( 2 ).

2. The vehicle wheel rim as claimed in claim 1 , wherein a cavity ( 14 , 26 ) is formed between the shell elements ( 4 , 5 , 20 , 21 ).

3. The vehicle wheel rim ( 1 ) as claimed in claim 2 , wherein the shell elements ( 4 , 5 , 20 , 21 , 30 , 31 , 32 ) are connected to one another in such a way that they overlap ( 10 , 15 , 22 , 33 , 34 ) at least in regions.

4. The vehicle wheel rim ( 1 ) as claimed in claim 2 , wherein the shell elements ( 4 , 5 , 20 , 21 , 30 , 31 , 32 ) are connected to one another by adhesive bonding.

5. The vehicle wheel rim ( 1 ) as claimed in claim 1 , wherein the wheel disk ( 16 , 25 , 37 ) is formed by three shell elements ( 30 , 31 , 32 ), wherein the third shell element ( 32 ) is arranged as a link between the first shell element ( 30 , 31 ) and the second shell element ( 31 , 30 ).

6. The vehicle wheel rim ( 1 ) as claimed in claim 5 , wherein the third shell element connects the first and the second shell elements radially at the inside, in particular in the region of the conical hub region ( 35 ).

7. The vehicle wheel rim ( 1 ) as claimed in claim 1 , wherein the wheel rim well ( 2 ) and the wheel disk ( 16 , 25 , 37 ) are connected to one another in such a way that the connecting point ( 15 ) is of two-layer and/or three-layer and/or multi-layer form.

8. The vehicle wheel rim ( 1 ) as claimed in claim 1 , wherein the wheel disk ( 16 , 25 , 37 ) has an opening ( 7 ) in a region situated adjacent to the connecting point ( 15 ).

9. The vehicle wheel rim ( 1 ) as claimed in claim 1 , wherein the wheel disk ( 16 , 25 , 37 ) is connected to the wheel rim well ( 2 ) by adhesive bonding.

10. The vehicle wheel rim ( 1 ) as claimed in claim 1 , wherein the wheel rim well ( 2 ) is engaged behind by the wheel disk ( 16 , 25 , 37 ) at a region ( 12 , 13 ) adjacent to the connecting point ( 15 ).

11. The vehicle wheel rim ( 1 ) as claimed in claim 1 , wherein the wheel disk ( 16 , 25 , 37 ) and/or the wheel rim well ( 2 ) are produced from a carbon-fiber-reinforced plastic (CFRP).
