东方红履带式拖拉机在使用1500小时后,后桥及最终传动部分开始频繁出现故障,这些故障发生的根源95%以上是由后桥的最终传动往转向离合器窜油而造成的。窜油后造成: (1)制动不灵,操作失控,不能进行正常的转弯动作。 (2)主、从动片摩擦表面有润滑油,使两者摩擦系数降低,造成转向离合器打滑,使拖拉机难以进行重 Dongfanghong crawler tractors in the use of 1500 hours, the rear axle and the final drive part of the frequent failure, the root cause of these failures of more than 95% of the final drive by the rear axle steering clutch to channeling oil caused. After channeling oil caused by: (1) brake is not working, the operation out of control, can not be normal turning action. (2) The friction surfaces of the main and driven piece are lubricated, which reduces the friction coefficient between the two and makes the steering clutch slippery, making it difficult for the tractor to carry out the heavy
