The utility model relates to a commercial vehicle commander wheel hub assembly that changes oil, wheel hub assembly comprises wheel stud kit, the wear -resisting wheel hub inner oil seal of high performance, wheel hub inner bearing assembly, wheel hub, wave form spacer, wheel hub outer bearing assembly, spindle nose nut, spindle nose nut locking plate, combination bolts, the outer oil blanket of the wear -resisting wheel hub of high performance. The spindle nose nut is screwed up with the moment of torsion of regulation consecutively to this method, makes the wave form spacer between the outerbearing inner race roller assembly of wheel hub, the interior bearing inner race roller assembly of wheel hub produce irreversible plastic deformation, when the wheel hub pulling force reaches the setting, stops to screw up the spindle nose nut to bearing inner race roller assembly forms a rigidity wholly in making spindle nose nut, the outer bearing inner race roller assembly of wheel hub, waveform spacer, wheel hub. The utility model discloses reduce cost when can by a wide margin promote the maintenance mileage interval that has ordinary wheel hub assembly now, satisfying performance, toimprove maintenance interval mileage, easy maintenance, expense simultaneously low.
