Abstract
A vehicle tire inflation system includes an axle assembly with an axle housing having an air supply conduit. Air is provided to the air supply conduit from an air tank mounted on the vehicle. The axle includes least one wheel hub rotatably supported on the axle housing by bearings. A hub cap is mounted at one end of the wheel hub and has an inlet and an outlet interconnected by a passageway. Air flows from the air supply conduit to the inlet, through the passageway, and out the outlet. At least one pneumatic tire is mounted for rotation with the wheel hub and has a tire inlet. A hose connects the hub cap to the tire to route air from the hub cap outlet to the tire inlet.
