Patent number: 8528920Abstract: An adjustment assembly includes first and second connection points associated with a component. The second connection point is selectively adjustable to adjust a position of the component.

Publication number: 20100276904Abstract: An independent suspension includes a knuckle with a spindle that supports a rotating wheel component. An upright includes upper and lower portions that are coupled to the knuckle such that the upright and knuckle are movable relative to each other. An upper control arm is connected to the upper portion of the upright, and a lower control arm is connected to the lower portion of the upright.Type: ApplicationFiled: November 13, 2007Publication date: November 4, 2010Inventor: Gregory D.

Patent number: 7819411Abstract: An independent suspension includes upper and lower control arms that are coupled to a knuckle that supports a wheel assembly. A spring bracket is pivotally connected to the lower control arm. A drive shaft extends through an opening in the spring bracket to drive the wheel assembly. The spring bracket includes first and second support plates that respectively support first and second springs on opposite sides of the drive shaft. A torque rod is pivotally connected to the spring bracket. The torque rod and the upper and lower control arms are also mounted to a vehicle frame member. The torque rod, knuckle, spring bracket, upper and lower control arms, and vehicle structure cooperate to provide a six link control that accommodates large wheel jounce travel.Type: GrantFiled: May 2, 2006Date of Patent: October 26, 2010Assignee: ArvinMeritor Technology, LLCInventors: Edward J. Eshelman, Gregory D. Pavuk, Gordon Aaron Weeks

Patent number: 7625001Abstract: A vehicle suspension utilizes a shunt linkage assembly between first and second torsion springs to change effective lengths of the first and second torsions springs in jounce and roll modes of operation. A first lever arm couples the first torsion spring to a first wheel and a second lever arm couples the second torsion spring to a second wheel component. The shunt linkage assembly acts as a tension-compression link between the opposed first and second lever arms. During jounce the first and second torsion springs would have one effective length, and during roll the first and second torsion springs would have a shorter effective length to provide roll stiffness that is greater than jounce stiffness.Type: GrantFiled: May 12, 2006Date of Patent: December 1, 2009Assignee: ArvinMeritor Technology, LLCInventor: Gregory D. Pavuk

Patent number: 6666474Abstract: A suspension system provides a pair of walking beams mounted parallel to a longitudinal main frame of a vehicle subframe. The walking beams support tandem axles. The walking beams are mounted to lower outboard brackets extending from each axle. A spherical joint extending from each longitudinal end of each walking beam engages the lower outboard brackets. Each walking beam is constrained against fore-aft movement through a pair of watts linkages. The watts linkages are separated by a lateral torsion tube. Each walking beam is connected to its respective watts linkages through a revolute joint and pivot relative to the torque tube. A pair of tie-rods are attached between each watts linkages and a fixed support. The tie rods include spherical joints at each end. Each axle is further restrained by a V-rod attached to an upper bracket extending from each axle.Type: GrantFiled: May 17, 2002Date of Patent: December 23, 2003Assignee: Meritor Heavy Vehicle Technology LLCInventor: Gregory D.
