Abstract

A rim onto which a vehicle tire is pulled or can be pulled. The rim has a rim base with at least one device to absorb sound in the manner of a Helmholtz resonator, an air volume partly ring-shaped and at least one opening into the tire interior. The air volume of the Helmholtz resonator is formed by the rim base, by wall and/or web elements, which are arranged on the rim base at a distance from one another when seen in the axial direction of the rim, which are radially oriented, and which are at least partly circumferential, and by a covering element or by a covering element and transverse walls, which delimit the air volume in the circumferential direction. The covering element may be connected to the wall and/or web elements in a form-fitting manner or in a form-fitting and force-fitting manner and in an airtight manner.

First claim

The invention claimed is:

1. A rim onto which a vehicle tire is pulled, the rim comprising:
a rim well on which at least one device for absorbing sound in the manner of a Helmholtz resonator with an at least partially annular air volume and at least one opening to the tire interior is arranged, and
said air volume of the Helmholtz resonator is formed by the rim well by radially oriented and at least partially circumferential wall and/or web elements, which are arranged spaced apart from one another on the rim well as viewed in the axial direction of the rim, and
by a cover element or by a cover element and transverse walls, which delimit the air volume in the circumferential direction,
wherein the cover element is connected to the wall and/or web elements in a positively locking manner and in an airtight manner,
wherein the cover element is connected in an airtight manner to the wall and/or web elements and/or the rim well by at least one sealing element.

2. The rim of claim 1 , wherein the cover element has, for the radially and axially fixed connection of said cover element to the rim, side webs which are positioned radially and run in the circumferential direction of the rim with axially outwardly pointing positively locking means in the form of latching elements which for their part latch with groove-shaped cutouts which are provided in the wall and/or web elements by radial placing of the cover element onto a circumferential groove which is formed by the wall and/or web elements and the rim well.

3. The rim of claim 1 , wherein the cover element has transverse walls, which are configured in one piece with said cover element, for delimiting the air volume, which transverse walls for their part are supported with their free end on the rim well.

4. The rim of claim 3 , wherein the transverse walls which are formed by the cover element run in a radially oblique manner toward the rim well and are supported on the latter.

5. The rim of claim 1 , wherein the at least one sealing element extends into the contact region of the transverse walls of the cover element with the rim well.

6. The rim of claim 1 , wherein the at least one sealing element is configured as a separate attachment component or in one piece with the cover element.

7. The rim of claim 1 , wherein the cover element is of cup-like or shell-like configuration.

8. The rim of claim 1 , wherein the cover element has means for reinforcing said cover element.

9. The rim of claim 1 , wherein the cover element is composed of metal and/or plastic and/or composite material.

10. A vehicle wheel or a vehicle having a rim as claimed in claim 1 .

11. A rim onto which a vehicle tire is pulled, the rim comprising:
a rim well on which at least one device for absorbing sound in the manner of a Helmholtz resonator with an at least partially annular air volume and at least one opening to the tire interior is arranged, and
said air volume of the Helmholtz resonator is formed by the rim well by radially oriented and at least partially circumferential wall and/or web elements, which are arranged spaced apart from one another on the rim well as viewed in the axial direction of the rim, and by a cover element or by a cover element and transverse walls which delimit the air volume in the circumferential direction, wherein the cover element is connected to the wall and/or web elements in an airtight manner,
wherein the cover element firstly has, for the radially fixed connection of said cover element to the rim, side webs which are positioned radially and run in the circumferential direction of the rim, the free end of which side webs is formed in each case by an axially positioned flange, said flanges are oriented in the same direction and penetrating, by way of axial displacement of the cover element relative to the rim, into in each case one groove-shaped cutout which is provided in the wall and/or web elements, and secondly has, for the axially fixed connection of said cover element to the rim, a multiplicity of snap-in tabs which are arranged one behind another as viewed in the circumferential direction of the rim and point counter to the displacement direction, the free end of which snap-in tabs is snapped into a corresponding receiving groove of the rim in the mounted state of the cover element.

12. The rim of claim 11 , wherein the snap-in tabs are configured in one piece with the cover element.

13. The rim of claim 11 , wherein the receiving groove which corresponds to the snap-in tabs is formed by at least one wall or web element which is positioned radially to the outside, starting from the rim well, and runs around at least partially in the circumferential direction of the rim.

14. The rim of claim 11 , wherein the axially positioned flange which is arranged on that side of the cover element which lies axially opposite the snap-in tabs merges into an end flange which is positioned radially to the outside.
