转向失灵故障有2个特点:一是引发故障的原因较多,不易判定;二是处理由转向离合器引起的故障时,维修人员工作量很大。从推土机的结构及故障的成因来看,转向失灵故障大致可分成3个区块:第1个区块是转向室外机械操纵区块,第2个区块是转向室外液压传动区块,第3个区块是转向室内传动区块。在维修推土机转向失灵故障时,灵活应用“三分区块法”可以使检修思路更多条理性,减少检修过程中的盲目性,提高 Turn failure failure has two characteristics: First, the cause of the fault is more difficult to determine; the second is to deal with the clutch caused by the steering failure, the maintenance staff a heavy workload. From the bulldozer structure and the cause of the fault point of view, the steering failure can be roughly divided into three blocks: the first block is turned to the outdoor mechanical control block, the second block is turned to outdoor hydraulic drive block, the third A block is turned to the indoor drive block. In the maintenance of bulldozers turning failure, the flexible application of “three-block method ” can make the maintenance ideas more rational, reduce the blindness in the maintenance process, improve
