Patent ID: 8777248

Claim:
A motor-vehicle suspension system, comprising, for each wheel, at least one transverse control arm having an outermost end connected in an articulated way to a respective wheel support and an innermost end connected in an articulated way to a supporting structure of the motor vehicle in such a way that each transverse control arm guides the vertical movements of the respective wheel support by means of an oscillation in a plane that is substantially transverse with respect to the longitudinal direction of the motor vehicle, said system further comprising spring means that counter the vertical movements of the two wheel supports, constituted by a leaf spring set transversely with respect to the longitudinal direction of the motor vehicle, and constituting a unit separate from said transverse control arms, wherein said leaf spring is set centrally between said transverse control arms, with the end of the leaf spring connected to the innermost ends of said transverse control arms in such a way that the oscillations of the transverse control arms in the aforesaid substantially transverse plane cause a deformation of bending of the leaf spring, the connection of each transverse arm to the leaf spring being such as to enable rotations of the transverse control arm in a substantially horizontal plane with respect to the leaf spring and relative sliding between the connected ends of the arm and of the leaf spring in the longitudinal direction of the leaf spring.
