Abstract
An integrated wheel hub assembly includes a hydrostatic spindle assembly that has a spindle with a hydrostatic rotational power unit and integral high-pressure passageways therein, a wheel hub rotatably supported by the spindle assembly, and an axle shaft extending through the spindle for transmitting power from the hydrostatic unit to the wheel hub through a planetary gear set reducer. For radial compactness, the swashplate of the hydrostatic power unit resides outside the wheel hub.
