摘　　要：活塞弹簧式气制动阀作为控制阀,已广泛地应用于拖拉机挂车制动系统,气制动阀静特性直接影响拖拉机挂车机组的制动性能。为此,对我国拖拉机挂车气制动系主要控制元件之一的活塞弹簧式气制动阀静特性做了理论分析和试验研究,结果表明:气制动阀静特性不仅与几何尺寸、平衡弹簧刚度、输入气压及行程有关,而且与制造精度、装配质量和调整误差有关。Piston spring pneumatic brake valve is widely used as control valve for tractor-trailer braking system.Brake properties of tractor-trailer brake system are affected directly by static characteristics of pneumatic brake valve.Theoretical analysis and experiments have been made on the static characteristics of piston spring pneumatic brake valve that is one of the main control components for tractor-trailer brake system.The results show the static characteristic of piston spring pneumatic brake valve is not only affected by the geometric dimensions,equilibrium spring stiffness,input pressure and stroke,but also by machining,assembling and adjustment.
