The invention discloses a rear suspension system of a wide-body dump truck. The rear suspension system is characterized by comprising a frame, hinge pins, rubber damping blocks, an intermediate axle, a balance beam, limiting plates, lower reaction rods, a rear suspension frame, a balance shaft, an upper reaction rod support, upper reaction rods, a rear axle, a shaft head end cover, a rubber block, a spacer bush, a wearing plate, a transverse draw bar support and a transverse draw bar. The rear suspension system has the advantages that a balance suspension can assuredly only move in the perpendicular direction under the effect of the gravity, and vibration can be buffered by the rubber block and the rubber damping blocks; the balance beam is allowed to rotate around the balance shaft, the spacer bush can assuredly rotate along with the balance beam when the balance beam rotates around the balance shaft, and accordingly friction between the rubber block and the spacer bush can be prevented; the intermediate axle and the rear axle can rotate around the balance shaft within small angular ranges, so that load on the intermediate axle is assuredly basically identical to load on the rear axle; the cost and the fault rate of a rear suspension can be effectively reduced.
