Motor vehicle suspension device
Abstract:
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). The system is also configured such that the distance (dl) remains smaller than 40 mm during a camber deflection (α) of 0° to −3°.
