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.
