A rear axle suspension damping system comprises a vehicle frame and two sets of double-rocker-arm structures arranged on the two sides of the vehicle frame respectively, each double-rocker-arm structure comprises a lower swing arm, an upper swing arm, a steering knuckle and a damper, the lower swing arms and the upper swing arms are hinged to the vehicle frame, the steering knuckles are connected between the outer sides of the lower swing arms and the outer sides of the upper swing arms, and the dampers are arranged on the vehicle frame. The inner ends of the shock absorbers are connected with the frame, a transverse telescopic device connected between the upper swing arms of the two sets of double-rocker-arm structures is arranged on the frame, and the transverse telescopic device comprises an air cylinder transversely arranged on the frame, an air pump and an exhaust valve, and the air pump and the exhaust valve are connected with the air cylinder through pipelines and used for driving the air cylinder to stretch out and draw back. The two ends of the air cylinder are connected with the upper swing arms of the two double-rocker-arm structures respectively. The transverse telescopic device can achieve adjustment of the height of the vehicle body chassis and the suspension hardness.
