Patent number: 8256781Abstract: A vehicle suspension, steering, damping and anti-roll system for a wheeled vehicle. Unlike most previous vehicle suspension and steering systems, this invention uses a rod-in-sleeve design for the front and rear suspension assemblies to allow vertical linear wheel knuckle movement of the wheels.

Patent number: 6547260Abstract: The vehicle includes a suspended running chassis (1) making it possible to define a longitudinal and vertical plane forming a reference on the chassis (1), the preferred running direction being parallel to the longitudinal plane, and at least two wheel connecting systems, the wheels (2) of which are not aligned relative to the longitudinal plane, the wheel connecting systems being mounted on the chassis (1) on either side of the latter in the transverse direction, each of the wheel connecting systems including a wheel (2) mounted on a support (5) by means of a suspension device allowing vertical deflection of the wheel (2) relative to the support (5), the suspensions being independent of one another. Each support (5) is mounted on the chassis (1) by means of a camber mechanism which includes a camber lever (4) and an actuating lever (40) making it possible to vary the camber angle of the corresponding wheel (2).Type: GrantFiled: March 13, 2002Date of Patent: April 15, 2003Assignee: Conception et Developpement Michelin S.A.Inventors: Daniel Laurent, Marc Sebe

Patent number: 6511078Abstract: A ground contact system for a vehicle having a wheel mounted on a wheel carrier, the wheel carrier being mounted on a support by a vertical suspension device, the support being mounted on a chassis by a load transfer arm on one side of which the support is articulated along an essentially horizontal geometrical camber axis, the load transfer arm being connected at its other side to the chassis along an essentially vertical geometrical axis, a camber control rod being pivotally mounted to the support some distance from the geometrical camber axis, the camber control rod being able to move transversely relative to the chassis, a triangulation-forming element connecting the load transfer arm to the chassis around the essentially vertical geometrical axis, such that it controls the moment about the essentially vertical geometrical axis.Type: GrantFiled: April 9, 2001Date of Patent: January 28, 2003Assignee: Conception et Developpement Michelin S.A.Inventor: Marc Sebe

Patent number: 6357770Abstract: The wheel suspension of the invention is a thin-profile wheel suspension system including spring and dampening mechanisms and an optional brake and drive motor, mounted to a suspension frame in a compact arrangement which permits all or most of the sprung components to be mounted within the volume enclosed by the rim of a wheel, and thus the wheel suspension of the invention may be referred to as an “in-wheel suspension”. The wheel suspension comprises a hub plate assembly including hub bearings and axle. The hub plate is mounted to a suspension frame by a motion-controlling sliding mount assembly, which connects the hub plate to the suspension frame while it permits the hub plate to slidably move in response to wheel loads. In the preferred embodiment, the suspension frame includes two forks, each fork mounting a sliding rail mount assembly comprising a slide-and-rail mechanism aligned vertically on the suspension frame and mounted to the hub plate.Type: GrantFiled: October 5, 2000Date of Patent: March 19, 2002Inventors: André Carpiaux, William D. T. Davis, Ivan Junju Huang, Andreas Kaiser, Alexander S. Ko, Martin Koebler, Timothy James Loew

Patent number: 6257604Abstract: A suspension assembly of a motor vehicle which assemble includes a wheel carrier and a guide member to guide the wheel carrier in relative translation. The wheel carrier is mounted on the guide member by means of a bar sliding in the guide member guided by rollers turning on roller ways arranged on the bar. The assembly includes a spiral spring acting between the bar of the wheel carrier and a guide member of an electromechanical machine that is operated to control the suspension deflection movements.Type: GrantFiled: November 12, 1999Date of Patent: July 10, 2001Assignee: Conception et Developpement Michelin S.A.Inventors: Daniel Laurent, Daniel Walser
