Rear suspension for a motor vehicle

Rear suspension (10) for a motor vehicle, comprising, for each rear wheel, a trailing arm (16), a wheel-carrying structure (18) fixed to a length (24) of the trailing arm (16) and an axle (44) fixed to the wheel-carrying structure (18) and defining the axis of rotation of the wheel,

• wherein the wheel-carrying structure (18) is made as a single piece integrally forming an upper support portion (38) having a seat (42) into which the wheel axle (44) is inserted and fixed, and a lower attachment portion (40) including a pair of vertical flat walls (34) which are parallel to each other, are arranged astride of said arm length (24) and have a plurality of through holes (46) in pairs;
• wherein a corresponding plurality of spacing members (28), each having a through hole (30) and a pair of end flat surfaces (32), are fixed to said arm length (24), said spacing members (28) projecting beyond vertical walls (26) of the arm length (24) in such a manner that said end flat surfaces (32) form abutment flat surfaces for the vertical flat walls (34) of the wheel-carrying structure (18);
• wherein the wheel-carrying structure (18) is fixed to the arm length (24) by means of a corresponding plurality of fixing screws (48) inserted into the through holes (46, 30) of the vertical flat walls (34) of the wheel-carrying structure (18) and of the spacing members (28), respectively, and
• wherein the rear suspension further comprises, for each rear wheel, a shock-absorber (20), wherein the transversely inner, vertical flat wall (34) of the wheel-carrying structure (18) forms a cylindrical projection (50) for connection to a lower end of the shock-absorber (20), said projection (50) extending transversely and having an axial through hole (46) through which one of the fixing screws (48) passes, whereby said screw (48) serves both for fixing the wheel-carrying structure (18) onto the arm (16) and for connection of the lower end of the shock-absorber (20).
