Pneumatic brake system for heavy truck

Abstract

The invention discloses an air pressure braking system of a heavy truck, and mainly relates to the field of air pressure braking of a truck. Including air compressor, main brake system, auxiliary brake system, the main brake system includes front axle brake system, rear axle brake system, parking brake system, it is characterized in that it also includes air processing unit APU, air The processing unit APU is used to distribute the gas generated by the air compressor to the main brake system and the auxiliary brake system respectively. The front axle brake system is equipped with a front axle air storage chamber, and the parking brake system is equipped with a parking storage chamber. The air chamber, the front axle air storage chamber and the parking air storage chamber together form a double-cavity air storage tank, the rear axle braking system is equipped with a rear axle air storage tank, the auxiliary braking system is equipped with multiple three-way pipes, and the air handling unit The APU is respectively connected with the dual-chamber air storage tank, the rear axle air storage tank and the tee pipe. The beneficial effect of the invention is that it can greatly reduce the weight and cost of the car and improve the loading capacity of the truck under the premise of ensuring the braking performance.

Description

technical field [0001] The invention relates to the field of braking of heavy-duty trucks, in particular to an air pressure braking system of heavy-duty trucks. Background technique [0002] Existing heavy trucks have a maximum load capacity, so the heavier the car itself, the smaller its cargo capacity, and the higher the cost of use and maintenance; for the braking system of heavy trucks, it is generally used Split structures such as air dryers and four-circuit protection valves require blowback air storage tanks, pressure regulating valves and related tube bundle joints, and the number of air storage tanks in the vehicle is too large and the volume is too large, and the auxiliary gas is mostly distributed by porous modules , greatly increasing its weight and cost, seriously restricting the loading capacity of heavy-duty trucks, and urgently need to be improved. Contents of the invention [0003] The object of the present invention is to provide an air pressure braking ...
