摘要
讨论了国外有关油压制动技术的应用及国内电空制动机的发展；分析比较了气液二态流体介质特性，提出了研制气液制动系统的设想。针对我国有关制动系统工况，讨论了气液制动阀结构型式，初步分析了系统油压力与结构轻量小型化关系。
The paper discusses foreign techniques applied to brake, and development of our electric-pneumatic brake equipment as well. Comparing the characteristics of the fluid mediums between air and liquid state, the pneumatic-hydraulic brake system is put forward. In view of our existing system, we design the structure model of related valve, proving the effect in which the high hydraulic pressure could improve the miniaturization of this structure.
