Abstract: A vehicular suspension device (1) comprises a wheel carrier (31) which is articulated relative to the suspension elements (18, 19). This connection is provided by rigid connection rods (6, 7). This additional degree of freedom permits variation of the camber angle (&agr;) independently of the suspension spring movement and of the deformations of its elements. The variation of the camber is preferably controlled by the forces sustained by the wheel (2) in the ground contact area (AC) of the tire. This is obtained by a configuration in which the movements of the wheel (2) relative to the body (5) of the vehicle allow an instantaneous center of rotation (CIR r/c) which is situated beneath the plane of the ground (S).

Abstract: An independent suspension for the front wheels of a motor vehicle with a steering knuckle that is pivotable for steering purposes, has a lower end mounted on a lower link and an upper area supported firstly by a coupling rod to this lower link and secondly by an upper link to the vehicle body.

In either case, the steering knuckle requires one less articulation point so that the steering knuckle takes up less space in the immediate vicinity of the wheel.
