1. A vehicle comprising:

  • a rolling and suspended chassis, at least two ground contact systems each comprising a wheel, said ground contact systems being mounted on said chassis transversely on either side thereof, the wheel of each ground contact system being mounted on a wheel carrier, the wheel carrier being mounted on a support by a vertical suspension device that permits suspension travel movement of the wheel carrier relative to the support, the suspension travel movement taking place in the plane of the wheel, the suspension travel movement being sufficient to permit the vertical suspension movement required, and each support being mounted on said chassis in a manner that makes it possible to incline each wheel relative to said chassis in order to impose on the planes of said wheels a camber angle of the desired amplitude, by inclining the wheels relative to the ground, each support being mounted on said chassis by a load transfer arm, at one end of which the support is articulated along an essentially horizontal geometrical camber axis, said load transfer arm being connected at its other end directly to the chassis along an essentially vertical geometrical axis, a camber control rod being pivotally mounted to each support at a location spaced away from the geometrical camber axis, the camber control rod being able to move transversely relative to the chassis, and a triangulation-forming element connecting each load transfer arm to the chassis, such that it controls moments about the essentially vertical geometrical axis.
