The invention relates to a ground contact system for the front or rear wheel set of a motor vehicle, of the type including a composite spring leaf, and to a method for producing said ground contact system. The ground contact system comprises: a composite spring leaf (1) which is to be mounted via the ends (6 and 7) thereof to the wheel set and which has two faces, namely an upper face (2) and a lower face (3), defining two longitudinal edges (4 and 5) connected by the aforementioned ends; and two vehicle chassis (10 and 11) supporting structures (8 and 9) which are mounted to the leaf close to the ends thereof and which each comprise two resilient hinges (14 and 15) to be connected to the chassis and positioned close to the longitudinal edges. According to the invention, each supporting structure is pressed against the faces of the leaf by means of at least one non-bonded elastomer layer, thereby clasping the leaf transversely. Moreover, the leaf and/or each structure comprise means (2b, 3b, 12b, 13b) for transversely stiffening the aforementioned layer, which are designed to increase the stiffness thereof in the direction transverse to the leaf, so as to oppose any rotation of the wheel set about a vertical axis. |
