Patent number: 6869091Abstract: A method for enhancing the physical characteristics of a localized area of a suspension component by adding material to the points of high stress without a significant increase in weight or diameter of the suspension component. The material is in the form of a sleeve added to the exterior surface of the suspension component, a core added to the interior surface of a tubular suspension component, winding filaments, or powered material.Type: GrantFiled: November 7, 2000Date of Patent: March 22, 2005Assignee: Meritor Suspension Systems CompanyInventors: Gerald D. Anderson, Michael W. Mattice, John M. Khoury, Thomas M. Drouillard, Kermit G. Rowe, III, David I. Fretwell, Alistair B. Lovett

Publication number: 20040232648Abstract: An apparatus for adjusting vehicle height, the apparatus being disposed between a vehicle body and a wheel assembly, the apparatus including a first suspension coil spring adapted to be connected to the vehicle body, a second suspension coil spring adapted to be connected to the wheel assembly, the second suspension coil spring being different in diameter from the first suspension coil spring and arranged in serial relation to the first suspension coil spring in an axial direction thereof, and an actuator substantially disposed within an inside space defined by the first and second suspension coil springs. The actuator is operative to axially move one of the first and second suspension coil springs relative to the other thereof.Type: ApplicationFiled: May 20, 2004Publication date: November 25, 2004Applicant: NISSAN MOTOR CO., LTD.Inventor: Toshiyuki Ohki

Publication number: 20040173986Abstract: A suspension system for chassis and/or body sprung weight and a plurality of wheel axle supports to carry a portion of the unsprung weight. The system has a load spring between the chassis and/or body and wheel axle support preloaded to a ride height. A member between the wheel axle support and the chassis and/or body exerts increasing force with motion of the unsprung weight relative to the chassis and/or body. The member has increasingly less force on the load spring during jounce beyond the ride height as the member resists the motion of unsprung weight. The member free length of travel cooperates with the load spring jounce deflection so the travel and the deflection overlap as the member moves. The member is a coil, tension or air spring in tension or compression. The load spring constant K carries sprung weight and the member constant KTresists the rebound motion of the sprung weight so K to KT is a function of the amount of roll resistance.Type: ApplicationFiled: March 16, 2004Publication date: September 9, 2004Inventor: Peter E. Bryant

Patent number: 6637561Abstract: A suspension system for a vehicle includes a dynamic absorber mass having a mass smaller than the sprung mass of the vehicle and a spring system supporting the dynamic absorber mass for out-of-phase coaxial motion with the vehicle and tuned to the ride frequency of the vehicle for damping ride frequency perturbations from the vehicle.Type: GrantFiled: November 11, 1999Date of Patent: October 28, 2003Assignee: Raytheon CompanyInventors: David C. Collins, Robin Hossfield, Joaquim A. Bento

Publication number: 20030132593Abstract: A spacer apparatus for insulating a beam bushing assembly of an axle/suspension system from direct metal-to-metal contact with the vehicle frame hanger on which the assembly is pivotally mounted. In one embodiment, an integrally-formed one-piece apparatus includes a spacer disk portion and collar portions, whereby the collars provide a complementary fit of the spacer apparatus on the bushing assembly mounting tube, and generally prevents or minimizes relative movement between the spacer disk and bushing assembly. In other embodiments, one or more load dissipation structures mounted on or forming a part of the beam and/or its bushing assembly prevent substantially non-planar surfaces of the assembly from contacting a spacer disk by increasing the bearing area of those surfaces which contact the disk. These apparatus generally eliminate excessive wear or damage to the spacer disk and possible resulting damage to the axle/suspension system.Type: ApplicationFiled: January 16, 2002Publication date: July 17, 2003Inventors: Joseph M. Ross, Phillippi R. Pierce, John E. Ramsey, Warren M. Schneider

Publication number: 20030122341Abstract: A suspension assembly for a motor vehicle includes upper and lower control arms pivotally attached to a frame member of the vehicle. A knuckle arm pivotally attaches to the upper and lower control arms moves along a substantially vertical axis in response to wheel movement caused by an uneven road surface. An actuation link is attached to one of the control arms at one end and to a damper assembly at another end. The damper assembly is disposed substantially within the frame member along a second axis transverse to vertical movement of the wheel and is actuated along the transverse axis in response movement of the control arm along the substantially vertical axis.Type: ApplicationFiled: January 2, 2002Publication date: July 3, 2003Inventors: Mark C. Smith, Daniel E. Whitney, Robert P. Carlstedt, Eric Stephen Geib, Steven M. Foster, Richard M. Clisch, Shan Shih, Juan Jose Marcos Munoz
