本文分析了农用挂车断气制动系统的结构和工作原理。指出了它的随动性差,造成制动粗暴等缺点。通过道路实验和动态特性的测定,进一步证实了它的缺点。研制了一种新型充断气制动系统来代替国内现行的《NJ141-77农用挂车》断气制动系统。
This paper analyzes the structure and working principle of the outage braking system of agricultural trailer. Pointed out that its follow-up is poor, resulting in brake and other shortcomings. Through the road test and the determination of dynamic characteristics, it further confirmed its shortcomings. A new type of expiration-air brake system has been developed to replace the existing “NJ141-77 agricultural trailer” out-gassing braking system in China.
