工程机械液力传动系统包括变矩器、变速器、转向离合器油路系统，因其传动负荷大，连续工作时间长，油温过高便成为常见故障之一。下面分析油温过高的危害与原因。１油温过高的危害 液力传动系统的设计油温一般为 ７０～１１０℃，但实际上当油温达到１００℃时就存在着故障隐
Hydraulic transmission system engineering machinery, including torque converter, transmission, steering clutch oil system, because of its transmission load, continuous working time, high oil temperature has become one of the common faults. The following analysis of the dangers and causes of excessive oil temperature. 1, the danger of excessive oil temperature Hydraulic transmission system design oil temperature is generally 70 ~ 110 ℃, but in fact when the oil temperature reaches 100 ℃ there is a fault hidden
