大型养路机械YZ-1型空气制动机的研制

Development of YZ-1 air brake for large-size track maintenance machinery

针对进口大型养路机械空气制动机存在的问题，根据国内机车制动机的原理，设计制造了适合国情的大型养路机械空气制动机，并通过计算和装车运行考核，证明该制动机设计合理，能满足使用要求。

In view of current problems in air brakes for imported large-size track maintenance machinery,an air brake for this application is designed and built according to the principle of air brakes for domestic-made loc0motives. After calculation and on-board test run,this air brake proves to be reasonable in design and can meet all aspects of operating requirements.
