摘要
随着车辆走行距离的增加，车轴轴承润滑脂有逐渐老化的倾向，但在走行７５万ｋｍ以后，所有参数均在管理基准以内。因此，电动车车轴轴承润滑脂的解体检查周期可以延长至６０万ｋｍ。
With the increase of car running distance,the lubricating grease on car axle bearings has the trend of aging gradually.But after running for 750 000 km,all the parameters are within the management criterion.Therefor,the disassembling inspection period for lubricating grease on electric motor car axle bearings can be prolonged to 600 000 km.
