摘要
为解决某车辆在行驶过程中分动器输入后端盖烧蚀的问题,从润滑能力设计、分动器漏油、润滑油加注量、应急泵故障吸油、润滑油道堵塞、润滑油泵故障等方面分析故障机理,得出故障的主要原因为润滑油加注量不足,导致底部输出齿轮飞溅的油量过少,仅依靠飞溅润滑造成轴承润滑不良,并通过故障复现证明了故障分析定位的准确性。
In order to find out the cause of ablation of transfer case input rear end cover of a vehicle in the driving process,this article analyzed the failure mechanism in lubrication capacity design,oil leakage from transfer case,amount of lubricating oil filling,faulty oil absorption of emergency pump,lubricating oil passage blockage,failure of lubricating oil pump and so on,and concluded that this failure was mainly caused by insufficient amount of lubrication oil filling,resulting in insufficient amount of oil splashed from the output gear in the bottom,which caused poor lubrication of the bearing.Failure reproduction proved accuracy of the failure analysis and positioning.
