  • Patent number: 6688620
    Abstract: A vehicular suspension device comprises a wheel carrier which is articulated relative to the suspension elements. This connection is provided by rigid connection rods. This additional degree of freedom permits variation of the camber angle 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 in the ground contact area of the tire. This is obtained by a configuration in which the movements of the wheel relative to the body of the vehicle allow an instantaneous center of rotation which is situated beneath the plane of the ground.

  • Publication number: 20030071430
    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).
