Description

[0025] Additional advantages and details of the invention result from the embodiment examples described below and in reference to the drawings. In the drawings:

[0026] FIG. 1 shows a wheel according to the invention of a first embodiment,

[0027] FIG. 2 shows a wheel according to the invention of a second embodiment, and

[0028] FIG. 3 shows a wheel according to the invention of a third embodiment.

[0029] FIG. 1 shows a wheel 1 according to the invention, suitable for a motor vehicle such as a motorcycle or an automobile, in a partial cut view. It comprises a rim 2 with a rim well 3 as well as a tire 4 mounted on the rim. The interior of the tire 4 is filled with air.

[0030] In the interior of the wheel 1 or of the tire 4, a material 5 adsorbing molecules contained in the air is provided, which is, for example, activated charcoal. The material 5 here is in the form of a loose bulk material, for example, in the form of a granulate 6 or larger pellets. As can be seen, the material 5 is arranged around the rim well 2 and densely packed. In order to fix it in this position, a holding means 7 is provided, consisting here of an air-permeable and flexible cloth or woven fabric 8, for example, a woven filter medium, which is substantially hose-shaped and appropriately filled with the material 5. The material 5 can be appropriately sewn into the cloth or woven fabric 8, for the purpose of which corresponding pocket-like recesses 9 are formed by corresponding tucks 10 or the like. In the example shown, two such filled holding means 7a, 7b, each extending 180 degrees, are represented, which complement each other to form an annular shape which surrounds the entire rim well. More than two such holding means 7 are also conceivable. The fixing occurs preferably by gluing on the rim well.

[0031] By means of the introduced material 5, a clearly larger volume of air can be introduced into the tires 4, that is to say can be stored in the interior, since the material 5, due to its extremely large surface area, adsorbs the molecules contained in the air, so that in a manner of speaking a virtual volume increase can be achieved. In this manner, due to a resulting reduction of the spring stiffness, the driving comfort can be improved without entailing a deterioration of the rolling resistance, the load capacity and the driving dynamics.

[0032] FIG. 2 shows a second embodiment example of a wheel 1 according to the invention, wherein identical reference numerals are used for identical components. Here too, a material 5 is provided on the rim well 3, for example, again an activated charcoal in the form of a granulate 6. The latter in turn is accommodated in a corresponding holding means 7, wherein the holding means 7, here a stable, housing-like holding means, is provided with a plurality of perforation openings 11, through which the air molecules can penetrate into the interior. Again, two holding means 7a, 7b are shown, each running circumferentially through 180 degrees and connected to form an annular shape. These holding means 7a, 7b, that is to say the half-shell housings, are made, for example, of plastic. They too are preferably secured via an adhesive connection on the rim well.

[0033] Finally, FIG. 3 shows a wheel 1 according to the invention, in which the material 5 in pressed form, that is to say in stable form, is applied, again preferably glued, to the rim well 3. Here too, two halves are provided, namely the sections 5a and 5b which in turn complement each other to form an annular shape. The respective pressed bodies are thus adapted to the shape of the component on which they are arranged. Thus, in this case, the shape of the rim well 3. Special holding means are not necessary here due to the pressing of the material 5, which is again activated charcoal, for example.
