A motor-vehicle suspension system (1) of the MacPherson type comprises a pair of wheel supports (3), and two shock absorbers (2) each having a body bolted to a corresponding wheel support (3) with a top end connected to the structure of the motor vehicle. A leaf spring (4) that counters the vertical movements of the two wheel supports (3) is set transverse to the longitudinal direction of the motor vehicle. The leaf spring (4) is made of a single piece having opposite ends each having a forked shape, with two prongs (7, 70) made of a single piece with said leaf spring (4). The leaf spring (4) is connected to the structure of the motor vehicle via four elastic supports (E5) and the suspension system (1) does not comprise other connection elements between each wheel support (3) and the structure of the motor vehicle so that the components of the suspension can be assembled on the leaf spring (4) prior to installation on the structure of the motor vehicle. One of the two prongs (7, 70) of each end of the leaf spring (4) is connected to the corresponding wheel support (3) by means of an elastic support (E2) in the form of a bushing with axis parallel to the longitudinal direction of the motor vehicle, having an external cylindrical reinforcement inserted in a metal terminal connected to the leaf spring (4), and the other prong (7, 70) of each end of the leaf spring (4) is connected to the corresponding wheel support (3) by means of a ball joint (E1) having an external cylindrical reinforcement inserted in a seat of the leaf spring (4).
