Abstract
A wheel mounting hub system includes a hollow stationary hub carrier with an inner surface and a rotating hub located radially within the stationary hub carrier throughout at least a portion of its axial length. A planetary gear train including a sun gear and planet gears mounted on webs formed on the rotating hub is located within the stationary hub carrier. The planetary gear train includes a ring gear located on the inner surface of the stationary gear carrier in mesh with the planet gears. Axially spaced annular roller bearings are located between the rotating hub and the inner surface of the stationary hub. Outer bearing races for the roller bearings are formed on the inner surface of the stationary hub carrier and inner bearing races are located on the outer surface of the rotating hub.
