  • Linkage system for suspension
    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.
    Type: Grant
    Filed: January 11, 2007
    Date of Patent: March 30, 2010
    Assignee: ArvinMeritor Technology, LLC
