Patent number: 8645027Abstract: A method of adjusting the angular rolling position of the plane of a motor vehicle wheel, in which the wheel is mounted on a vehicle so that the plane of the wheel can present a static angular position and a safety angular position, the method providing for the plane of the wheel to be maintained in the static angular position when the wheel is rolling and, in case of detection of at least one critical rolling parameter, for the wheel plane to be shifted to a safety angular position for a predetermined time period before the plane of the wheel is returned to the static angular position. A wheel mounting of a motor vehicle in which the method can be implemented is provided.Type: GrantFiled: May 16, 2008Date of Patent: February 4, 2014Assignees: Societe de Technologie Michelin, Michelin Recherche et Technique S.A.Inventors: Michel Blondelet, Alain Vaxelaire, Christophe Pyszczek

Patent number: 7793946Abstract: A suspension device (1) for suspending a wheel (2) with respect to the body (8) of a vehicle. The device allows a substantially vertical suspension movement and allows the wheel carrier (3) to move in terms of camber with respect to the body of the vehicle. The device comprises a slide (5) and a lower arm. The slide comprises an upper part (52) and a lower part (51) which can move one with respect to the other, the upper part being connected to the body and the lower part being connected to the wheel carrier. The device further comprises a rocker (4) articulated in the camber plane, on the one hand, to the lower arm and, on the other hand, via a link (7) to the wheel carrier, the rocker further being articulated in the camber plane to the lower part of the slide.Type: GrantFiled: September 28, 2006Date of Patent: September 14, 2010Assignee: Michelin Recherche et Technique S.A.Inventor: Alain Vaxelaire

Patent number: 7712748Abstract: A support system (3,5,54,55) designed to connect a wheel (2) to suspension elements (4,41,74,75,76) of an automobile, the support system including a cambering device that confers upon the wheel carrier (3) a degree of camber freedom relative to the suspension elements, the cambering device including a triple hinge (5), the triple hinge including three essentially longitudinal axes, the triple hinge including two flanges (52, 53) and two levers (54, 55), each of the levers being respectively attached to one of the two flanges. The levers are connected on the one hand to the wheel carrier (3) and on the other hand to the suspension elements. The camber movement of the wheel carrier takes place around an instantaneous centre of rotation (CIR r/s), a lateral distance “dl” separating the transverse position of the instantaneous centre of rotation (CIR r/s) from the transverse position of the wheel base (BR).Type: GrantFiled: June 20, 2005Date of Patent: May 11, 2010Assignee: Michelin Recherche et Technique S.A.Inventors: Michel Deal, Alain Vaxelaire, Davy Vernier
