<p>The present invention is directed to a rotary air coupling (30) that distributes air to tires mounted on a rotating hub of a driven axle. The coupling is positioned outside of the axle and hub bearings (16, 17) avoiding interference with the wheel assembly. And the rotary coupling is connected to the brake mounting plate (22) and the wheel hub to take advantage of their closely held tolerances.</p> |
