A pressure shock mitigation system of a wheeled armored missile transporter vehicle relates to the technical field of wheeled vehicles for military use, and is characterized by comprising shock absorbers and a pressure conversion device. The pressure conversion device comprises hydraulic cylinders and a connecting pipe mechanism. Lower ends of the hydraulic cylinders are connected with wheels. The connecting pipe mechanism is connected to upper portions and lower portions of the hydraulic cylinders. The shock absorbers are arranged on the connecting pipe mechanism, and can be suction shock absorbers or compression shock absorbers, or both. The space over each wheel can be saved, and the amplitude of entire lifting or diagonal lifting of the vehicle body in the height direction can be increased. Moreover, as being connected by means of the connecting pipe mechanism, the shock absorbers can be connected at any positions of the vehicle body, which is conducive to saving space, and therefore, the vehicle can be avoided from great bumping in a cross-country process, and is comfortable for driving and riding without causing fatigue easily. In addition, the pressure shock mitigation system of the wheeled armored missile transporter vehicle is capable of realizing entire lifting or single side tilting of a chassis, thereby being conductive to solders completing special actions and tasks in complex environments by combining equipment.
