The invention discloses an air pressure braking system of a heavy-duty truck, and mainly relates to the field of truck air pressure braking. The system comprises an air compressor, a main braking system and an auxiliary braking system; the main braking system comprises a front axle braking system, a rear axle braking system and a parking braking system. The system is characterized in that the system comprises an air processing unit APU, and the air processing unit APU is used for distributing air generated by the air compressor to the main braking system and the auxiliary braking system; a front axle air storage cavity is formed in the front axle braking system, a parking air storage cavity is formed in the parking braking system, the front axle air storage cavity and the parking air storage cavity jointly form a double-cavity air storage cylinder, a rear axle air storage cylinder is arranged in the rear axle braking system, and a plurality of three-way pipes are arranged in the auxiliary braking system; and the air processing unit APU is connected with the double-cavity air cylinder, the rear axle air cylinder and the three-way pipe. The invention has the beneficial effects that on the premise of ensuring the braking performance, the weight and the cost of an automobile can be greatly reduced, and the loading capacity of a truck is improved.
