The invention discloses a rear rubber spring balanced suspension system for a heavy-duty dump truck, belongs to the technical field of automobile parts, and can solve the problem that a rubber main spring of an existing rubber spring balanced suspension system is prone to being stretched and damaged. The rear rubber spring balanced suspension system for the heavy dump truck comprises a saddle, a balance beam and a limiting assembly; the limiting assembly comprises a limiting box and a limiting piece; the limiting box is fixedly arranged on the balance beam; and the limiting piece comprises a transverse plate and a vertical rod, one end of the vertical rod is perpendicularly arranged on the surface of the transverse plate, a through hole is formed in the top face of the limiting box, the transverse plate is arranged in an inner cavity of the limiting box, and the other end of the vertical rod penetrates through the through hole to be fixedly connected with the saddle so that the limiting piece can move in the height direction of the limiting box to limit the relative distance between the saddle and the balance beam. The balanced suspension system can well prevent the rubber main spring from being stretched and damaged, and is simple in structure, convenient to manufacture and not prone to failure.
