Abstract: 1.转向不灵 方向盘操纵不灵,即行驶时车架摇摆,转动方向盘费力,或时轻时重都视为转向不灵.其产生原因及排除方法如下:液压操纵系统或转向油缸中有空气,若液压系统中有空气,一般可查看油箱有无泡沫产生,若有则为系统中有空气;可排除系统中的空气.若转向油缸中有空气,依次打开转向油缸放气塞,直到未冒气泡为止. 2.供油压力不正常 其常见原因有:溢流安全阀阀座磨损或被污物堵塞;安全阀弹簧失效,阀座顶开;油泵供油压力不足,主要是自紧油封损坏,致使油底壳的机油增多,而液压油箱中油量减少;油泵元件磨损;三阀分配器中回油阀被污物垫起,关闭不严或阻尼孔阻塞.若油泵供油不正常,则可卸下三阀分配器中的回油阀进行清洗,疏通油路即可.
