Double-pipeline gas transmission braking topology framework for heavy-duty truck

Abstract

The present invention is a dual-pipe air brake topology structure for heavy-duty trucks, including a main control air brake pipeline (1), an auxiliary control air brake pipeline (2), and a three-way pipe ( 3) and the pneumatic brake cylinder (4), a total of 4 parts, when the heavy-duty truck urgently needs to brake and stops moving forward, if the main control pressure gauge (13) in the main control air brake pipeline (1) The pressure is less than 0.8 MPa. It will cause the brake to fail and cause a safety accident. At this moment, the driver starts the auxiliary control air brake pipeline (2) at once, forcing the pressure in the air brake cylinder (4) to rise to greater than 0.8 MPa, so the spring in the cylinder is unclamped, driving the piston in the cylinder to move down, The push rod extends outward, and the brake disc coincides with the linkage disc in the car to achieve the purpose of rapid braking. The invention has clear design idea, simple overall structure and convenient operation method, can control the wheels quickly, accurately, effectively and safely, and maintain the best braking force, so as to realize increased braking speed, shortened braking distance and stable braking. Moving direction, to ensure the safety of people and vehicles.

Description

technical field [0001] The invention relates to an automobile brake structure, in particular to a dual-pipeline air transmission brake topology structure for heavy-duty trucks. Background technique [0002] With the rapid development of expressway construction in my country, the domestic truck market is becoming more and more perfect, and the number of trucks is increasing. Especially, heavy-duty trucks have become the first choice for people to transport goods. However, highway traffic is often affected by weather, road conditions and human factors, and the safety problems brought about by it have aroused people's vigilance and attention more and more. Braking is one of the important measures for the active safety of heavy-duty trucks. It can be said that if a heavy-duty truck does not have a braking function, it cannot be loaded. This is like the self-control of a car driver, both inseparable and equally important. [0003] At present, the commonly used braking facility ...

AI Technical Summary

Problems solved by technology

Although it can play the role of emergency braking, when the pressure of the gas storage tank does not reach 0.8 MPa, it is easy to cause the tires to lock up and the brakes will fail, the tires will change from rolling to sliding, the friction coefficient will decrease, the adhesion will decrease, and lateral Displacement, sideslip tire blowout, rear-end collision and other accidents, resulting in national property loss and people's life safety
