Abstract:
1. Arm for a motor-vehicle independent suspension, for connecting the wheel-carrier of a vehicle wheel to the vehicle body, the arm comprising a pair of transverse rods articulated at their transversely outer ends to the wheel-carrier and at their transversely inner ends to the vehicle body, and at least one pair of connecting elements which connect the rods to one another and are formed such that they have a bending stiffness in a plane greater than the bending stiffness in a direction perpendicular to said plane, the arm being capable of controlling two translational degrees of freedom along the axes of the rods and, by virtue of the geometry and the torsional stiffness of the rods, as well as of the geometry and bending stiffness of the connecting elements in said plane, a first rotational degree of freedom about a first, mainly transverse and horizontal axis, wherein the rods converge in such a manner that the arm has an elastic centre located outside its physical envelope and is thus capable of controlling, by virtue of the geometry and bending stiffness of the rods, as well as of the geometry and bending stiffness of the connecting elements in the aforesaid low-stiffness perpendicular direction, a second rotational degree of freedom about a second, mainly vertical axis and wherein at least one of said connecting elements is formed by a bush, the orientation of which affects the orientation of said first and second axis.
