  • Patent number: 7686314
    Abstract: At least one end of a longitudinally extending control link arm includes a laterally extending tubular portion that receives a bushing assembly. The tubular portion is used to pivotally secure an end of the control link arm to a vehicle structure or axle component. The bushing assembly is positioned within the tubular portion such that radial stiffness is distributed away from a center of the tubular portion. This configuration provides a high conical rate and provides auxiliary roll stiffness such that a sway bar is not required.

  • Patent number: 7350606
    Abstract: A drive unit for a vehicle wheel assembly includes an input gear set driven by an electric motor, a planetary gear set driven by the input gear set, and an output shaft driven by the planetary gear set. An adapter is used to attach a wheel rim and a brake component for rotation with the output shaft, which is rotatably supported by a wheel bearing. The input gear set and the planetary gear set are positioned outboard of the electric motor and inboard of the brake component. The brake component can be easily removed without requiring removal of the planetary gear set or any wheel bearings. Only the wheel rim and the adapter have to be removed in order to remove the brake component.

  • Patent number: 7204339
    Abstract: A wheel end assembly includes an output shaft that is directly mountable to a wheel adapter to drive a vehicle wheel. A gear assembly is coupled to the output shaft to transfer driving force from an input to the output shaft. The gear assembly includes an output gear that is directly coupled to the output shaft. Thus, the wheel adapter and output gear are both supported directly on the output shaft. The gear assembly and output shaft are substantially enclosed within a housing that is mounted to a non-rotating vehicle component. The output shaft is solely supported by a pair of bearings for rotation relative to the housing. The bearings are installed for direct engagement with the output shaft and housing.
