ZL50C型轮式装载机由于重量较大,为使转向操纵轻便,采用了全液压流量放大转向系统。在使用过程中,ZL50C型轮式装载机液压转向系统最常见的故障现象是转向沉重和转向不稳等,分析和排除这些故障,有助于更好地了解和维护车辆的液压转向系统。介绍了ZL50C型轮式装载机全液压流量放大转向系统的工作原理,通过对ZL50C型轮式装载机转向沉重故障现象的分析和排除,探讨了全液压转向系统转向沉重或转向不稳定的具体原因,并提出了装载机全液压转向系统使用和维护中应该注意的问题。
ZL50C wheel loader due to the weight, in order to make the steering operation light, using a full hydraulic flow amplification steering system. In use, ZL50C wheel loader hydraulic steering system is the most common symptoms of heavy steering and steering instability, etc., to analyze and eliminate these failures, help to better understand and maintain the vehicle’s hydraulic steering system. This paper introduces the working principle of ZL50C wheel loader full hydraulic flow amplifying and steering system. By analyzing and eliminating the phenomenon of ZL50C wheel loader turning heavy, this paper discusses the specific reasons of full hydraulic steering system turning heavy or steering instability , And put forward the problems that should be paid attention to in the use and maintenance of full hydraulic steering system of loader.
