摘　　要：全液压负荷传感转向系统具有转向灵敏可靠、轻便省力、性能稳定、安全可靠、高效节能等特点,转向抖动是转向系统较难迅速判定的故障之一。此类故障发生频率较低,但严重影响司机操作和转向器使用寿命。从转向系统是否进气、优先阀内部弹簧系数大小,转向器内部LS控制回路阻尼孔径大小等几个方面进行故障排查,分析产生转向器抖动原因及优化设计,进而消除转向抖动故障,防止损失扩大化。Bounces in a fully hydraulic loadsensing steering system.In view of trouble shooting in the steering system as an important and critical job we had to arrange and check the trouble causes including air ingression to the steering system,spring size in the pilot vale,retard orifice size in LS control circuit within steering device,etc before analyzing the bounces and put forth an optimal design there-for,thus eliminating the steering troubles and preventing expansion of the failure.

关 键 词：负荷传感 转向系统 转向抖动 优先阀
