Abstract
A hose-type structure is arranged essentially between the tire and the rim, which structure is connected at the end side with the environment and, by way of a valve, with the interior of the tire. The hose-type structure fills the tire during its rotating movement, and is locally squeezed from the environment side toward the tire interior, in which case the hose-type structure is provided in the area between the tire and the rim flange. A duct is provided in the rim flange or in the tire in the area of its bead chamfer, and at least partially receives the hose-type structure in the form of a hose. The geometry of the duct and of the hose-type structure is selected such that this air-conveying squeezing essentially takes place only as long as the internal tire pressure is below a desired value.
Claims7
An arrangement for filling air into a pneumatic tire, the arrangement comprising:
- a pneumatic tire arranged on a rim, both of which rotate together;
- and
- a hose-type structure, arranged between the tire and a rim flange of the rim, the hose-type structure includes a first side connected with the environment and a second side connected with an interior of the pneumatic tire, wherein the first and second sides are connected by a valve, and the hose-type structure is locally squeezed from the first side toward the second side during rotating movements of the tire in order to fill the tire.
