The invention provides a pneumatic ABS electric control inductive loading anti-lock brake execution system, comprising two ABS electromagnetic relay valves, an electronic load sensor, and a brake lamp switch; the pneumatic ABS electric control inductive loading anti-lock brake execution system is characterized in that an electric control inductive loading air-pressure adjusting valve, an air source control assembly and two balance pistons are added; wherein, the balance piston assembly is corresponding to the ABS electromagnetic relay valve; furthermore, the air inlet passage of the balance piston assembly is communicated with the output chamber B of the ABS electromagnetic relay valve; under the control of the size of the air pressure in the output chamber B, an anti-vacuum chamber E is communicated with the output chamber B or atmosphere through air passages; the electric control inductive loading air-pressure adjusting valve is fixedly arranged between two ABS electromagnetic relayvalves; two air outlets are correspondingly connected with the control ports of the two ABS electromagnetic relay valves; the air source control assembly comprises an eccentric shaft which is provided with a handle and arranged inside the valve body, a checking valve, two guiding valves, an air inlet passage, an air passage, and three air outlet passages with one end communicated with each other.The electronic load sensor of the invention can automatically adjust the braking air pressure with the change of the load of the shaft, and have high sensitiveness and excellent working performance.
Description
technical field [0001] The invention provides an air braking ABS electronically controlled load sensing anti-lock braking execution system, which belongs to the technical field of automobile braking. Background technique [0002] As my country's expressway backbone network has been basically formed, large-tonnage, long-wheelbase main vehicles, semi-trailers, and trailers with obvious cost advantages per ton-kilometer are also increasing year by year. When a long-wheelbase vehicle brakes urgently, the wheels are locked and slipping, resulting in extended braking distance, vehicle deviation or side skidding, and the vehicle loses its steering ability. Especially when the weather is bad and the road conditions are not good, traffic accidents are prone to occur. However, the existing ABS anti-lock braking system can solve the problem of brake lock, but it cannot solve the reaction time lag of the air brake system and the brake is soft under heavy load, and it cannot meet the lo...
