1.锁紧螺母松动导致转向失灵(1)故障现象1台TY160B型推土机使用一段时间后,出现向左转向困难故障。该故障逐渐严重,直至右侧也发生转向困难,且转向时柴油机转速明显降低。(2)结构原理该推土机转向是通过制动器与转向离合器配合操作实现的。其制动器为机械控制带式制动器,转向离合器为湿式、多片、弹簧压紧、液压分离式离合器。该转向离合器通过转向离合器轮毂、花键、锁定螺母与后桥轴连接,后
1 lock nut loose lead to failure (1) the phenomenon of failure 1 Taiwan TY160B bulldozers use for some time, turn left to appear difficult fault. The failure gradually worsened until the right side of the steering problems also occurred, and the steering speed significantly reduced diesel engine. (2) The principle of the structure The bulldozers steering through the brake and the steering clutch to achieve with the operation. The brake is a mechanical control band brake, the steering clutch is wet, multi-chip, spring compression, hydraulic clutch. The steering clutch is connected to the rear axle through a steering clutch hub, a spline, a lock nut and a rear axle
