AI Technical Summary
Technical Problem
In existing commercial vehicles, the valves of spring brake actuators are usually located far from the spring brakes, resulting in delayed pressure regulation, complex assembly, and inconvenient maintenance. Furthermore, stand-alone valve solutions increase component size and weight.
Method used
The regulating valve and the anti-double-acting valve are integrated into the spring brake actuator to form an integrated unit, reducing the amount of assembly work and enabling rapid response and optimized operating parameters through short-distance connection.
Benefits of technology
While achieving anti-lock braking and anti-double-action performance, it reduces assembly and maintenance costs, decreases component size and weight, and improves response speed and maintainability.
