<p>The invention concerns a vehicle axle crosspiece comprising a first tube (1) whereof one end is fixed to a wheel arm (Bd), located on one side of the vehicle, and whereof the other end is oriented towards another wheel arm (Bg) located on the other side of the vehicle, and a second tube (2) partly engaged inside the first tube and fixed in turn at its outer end to the other wheel arm (Bg), the inner tube (2) and the outer tube (1) being mutually linked by at least two anti roll articulations (3, 4) made of elastomeric material, spaced apart along the longitudinal direction of the tubes and housed between the outer surface of the inner tube and the inner surface of the outer tube, each anti roll articulation having its own particular radial stiffness. The anti roll articulations (3, 4), each assigned with a coefficient proportional to their radial stiffness (k3, k4) allow a gravity centre (OHgr;) which is closer to the wheel arm (Bd) linked to the outer tube (1) of the crosspiece than to the other wheel arm (Bg), for a symmetry of flexural rigidity.</p> |
