Abstract
The invention relates to a vehicle wheel, preferably a light alloy wheel, in which the compressed-air non-return valve is positioned axially in a valve unit (3a) in the center of the wheel hub (1), the pressure medium, air or other gases, being supplied either manually from the exterior via the valve (2a) or automatically from the vehicle side via the valve (2b) of the axial bore (9a). The pressure medium reaches the wheel base (35) and the tires via radial channels (9b) or pipes (9g) inside the wheel or the spokes. The axial and central valve (2a) allows the position of the valve to remain accessible irrespective of the position of the wheel, both for the manual filling of the tire from the exterior and for connection to the fully automatic tire pressure control system of the vehicle on the vehicle side. During operation, no shear forces or torques, which put a strain on wrist and elbow joints, are produced.
