PROBLEM TO BE SOLVED: To provide an improved integrated wheel hub assembly. SOLUTION: The integrated wheel hub assembly has a hydraulic spindle assembly 22 with a spindle 24 including a hydraulic rotating power part 40 and an integrated high pressure fluid passage, a wheel hub 12 rotatably supported by the spindle assembly, and a driving shaft 39 extended across the spindle so that the power is transmitted from the power part to the wheel hub by a planetary reduction gear 60. For miniaturizing in a radial direction, the rotary swash plate of the power part is provided apart from the wheel hub. COPYRIGHT: (C)2003,JPO
