| 摘 要： | 对我国拖拉机挂车气制动系主要控制元件之一—膜片式气制动阀静动特性做了理论分析和试验研究，通过适当改变气制动阀内部参数的方法，提高了其静动特性指标和拖拉机挂车机组的制动性能。试验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，还与制造精度、装配质量、调整误差有关，气制动阀的动特性不仅与平衡弹簧刚度有关，而且还与进气阀口内径和阀座硬度有关。

| Abstract: | Theoretical analysis and experiments are made on static and dynamic characteristics of diagraph spring pneumatic brake valve that are one of the main control components for tractor-trailer brake system. The optimization of static and dynamic characteristic parameters of brake valve is obtained by its interior parameters that are changed properly. The brake properties for vehicles pneumatic brake system are increased. The results show static characteristics of diagraph 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 as well, that the dynamic characteristics of diagraph spring pneumatic brake valve is not only affected by equilibrium spring stiffness, but also by intake valve inner diameter and valve seat hardness. |
