AI Technical Summary

Technical Problem

The existing empty and loaded vehicle valves have low output accuracy due to their purely mechanical structure during emergency braking, making it difficult to adapt to different load conditions and requiring secondary correction and adjustment.

Method used

It adopts a cooperative structure of valve body assembly, piston assembly and valve core assembly, combined with solenoid valve electronic regulation, to achieve precise regulation of air pressure by controlling the connection or disconnection of the pressure output chamber and the input chamber.

Benefits of technology

It improves the accuracy of brake pressure regulation, simplifies the structure, adapts to various load conditions, eliminates the need for mechanical adjustment, and avoids the impact of output sensitivity differences.
