<p>A motor-vehicle multi-link suspension system comprises, for each wheel, two lower transverse arms (T1, T2) and a substantially longitudinal or inclined lower arm, each having one end pivotally connected to a respective wheel support (S) and the opposite end pivotally connected to the motor-vehicle structure. In order to counteract vertical movements of the two wheel supports (S) there is provided a leaf spring (LF) arranged transversally with respect to the longitudinal direction of the motor-vehicle with its general plane lying horizontally. The leaf spring (LF) is supported by the motor-vehicle structure by means of elastic supports (8) arranged symmetrically at intermediate positions between the centre of the leaf spring and the ends thereof. The ends of the leaf spring are pivotally connected to the upper parts of the two wheel supports (S). The suspension comprises two jack-type shock absorbers (B) having their opposite ends swingably connected to the respective wheel support (S) and the motor-vehicle structure. The end portions (9) of the leaf spring (LF) fulfil also the function of triangular upper transverse arms of the multi-link suspension. Preferably the leaf spring is made of a composite material.</p> |
