Abstract: The suspension comprises, 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). The wheel-carrying structure (18) is made as a single piece 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) aligned in pairs. The arm length (24) forms a pair of vertical walls (26) to which three spacers, each having a through hole (30), are fixed, and a pair of end flat surfaces (32). The spacers (28) project beyond the vertical walls (26) of the arm length (24) in such a manner that their end flat surfaces (32) form two abutment flat surfaces for the vertical flat walls (34) of the wheel-carrying structure (18).
