A distributed hydraulic-pneumatic braking system and control method for a heavy-duty transport vehicle

Abstract

The invention discloses a distributed hydraulic-pneumatic brake system and a control method for a heavy-duty transport vehicle. The system includes a brake control system, a hydraulic brake system and an air pressure brake system. The braking system is arranged on the trailer; the control method is that the vehicle executes the conventional braking mode, the quick braking mode and the emergency braking mode according to the change speed of the brake pedal force at the beginning of braking, and the air braking system is flexibly designed according to the braking mode The advance amount is adjusted by electronic control; the hydraulic brake system uses drum brakes with better braking effect, the air brake system uses disc brakes with better heat dissipation performance, and the whole vehicle uses two kinds of brake systems , not only the high sensitivity of the hydraulic braking system, but also the strong braking force of the pneumatic braking system. Compared with the traditional braking system, the response speed of the system is faster, which improves the braking efficiency and Stability, safety and comfort.

Description

technical field [0001] The invention relates to a distributed hydraulic-pneumatic braking system and a control method of a heavy-duty transport vehicle, belonging to the technical field of vehicle braking. Background technique [0002] Heavy-duty transport vehicles are an important part of my country's road transport. Reports on heavy-duty transport vehicle safety accidents have always been common, especially in remote mountainous areas in my country. Complex road conditions often lead to safety accidents of heavy-duty transport vehicles. The country and the people have caused huge losses, and for special transport vehicles such as the military field, the occurrence of safety accidents may not only cause personal and property losses, but may also leak state secrets. Therefore, the safety of heavy-duty transport vehicles needs to be improved urgently. Among the many factors that affect the driving safety of heavy-duty transport vehicles, braking performance is the most importa...

Problems solved by technology

This invention is mainly aimed at small four-wheeled cars, with two sets of braking systems, but the space of small cars is limited, the adaptability is not strong, and the working method and layout of the brakes are not specifically described in the scheme, and a relatively traditional braking system is adopted at the same time. Brake comfort and safety are poor
