变 扭器油温过高是矿用汽车使用中常见而又危害极大的故障之一。变扭器正常工作时 ,油温一般应保持在70～90℃范围内 ,长时间运行在95℃以上 ,将直接导致变扭器工作失效。(1)表现为机械直接损坏 ,如橡胶密封件和挡位离合器片的烧蚀、变形、脆硬剥落等造成变扭器脱档、打滑或卡 Torque converter oil temperature is one of the most common and hazardous faults in mining vehicles. Torque converter normal work, the oil temperature should generally be maintained at 70 ~ 90 ℃ range, long run at 95 ℃ above, will directly lead to torque converter failure. (1) The performance of direct mechanical damage, such as rubber seals and clutch gear pieces of the ablation, deformation, brittle hard peel off caused by torque converter slip, slip or card
