摘　　要：采用负载敏感系统的履带起重机,在进行单边转向时常常出现熄火的现象,该文在不影响发动机效率的前提下,设计出一种改进方案:将两个行走系统的负载反馈口用管路连接,并在管路中间串联一个适当大小的阻尼,以此改善发动机与液压泵之间的功率匹配问题。实验结果表明,该方法可有效解决熄火问题,并且简单易行,有一定实用价值。Crawler crane,load sensing system often appears when unilateral steering flameout phenomenon,this article does not affect the efficiency of the engine under the premise,to design an improved solution the the load feedback mouth of two walking piping connections,and in the middle of the conduit in series with a properly sized damping,in order to improve the power matching between the engine and the hydraulic pump.The experimental results show that this method can effectively solve the flameout and simple,there are certain practical value.
