Mine loader is a kind of commonly used engineering machinery, and the working environment is relatively bad. When the mine loader is in field operation, due to the influence of many objective factors such as environment, temperature and construction conditions, the phenomenon of insufficient driving force will inevitably appear in the use of the equipment. This not only affects the normal work efficiency, but also increases the construction cost, and will have a serious impact on the construction plan and progress. Therefore, it is very important for the construction personnel to judge the fault of the loader.

矿用装载机的驱动不足的原因：

Reasons for insufficient driving of mine loader:

①装载机变速系统压力太低，负荷大会出现打滑的情况。按检查压力低的方法来检查变速阀、变速泵等。变速压力正常但工作仍然无力，并且从马达处向外冒油。此现象一般是变矩器旋转油封损坏，或罩轮与泵轮之间的o形密封圈出现损坏而造成的。

① The pressure of the loader transmission system is too low, and the load will slip. Check the variable speed valve, variable speed pump, etc. according to the method of checking low pressure. The shift pressure is normal, but the operation is still weak, and oil is flowing outward from the motor. This phenomenon is generally caused by the damage of the rotating oil seal of the torque converter or the damage of the O-ring between the cover wheel and the pump wheel.

②变速压力正常，工作无力，油温高，油底有铝沫。这种故障是变矩器的泵轮﹑导轮或Ⅰ﹑Ⅱ级涡轮出现损坏造成的，这种情况建议拆解变矩器进行检查。

② The transmission pressure is normal, the operation is weak, the oil temperature is high, and there is aluminum foam at the oil bottom. This fault is caused by the damage of the pump wheel, guide wheel or stage I and II turbines of the torque converter. In this case, it is recommended to disassemble the torque converter for inspection.

③如果是变速压力正常，行走可以，但吃土无力。这种现象大多是超越离合器损坏而造成，如超越离合器的三条压缩弹簧失效、隔离环断裂、内环凸轮或外环齿轮的滚柱工作面磨损比较严重等，一般应该拆解、更换零件或大超越离合器总成。

③ If the speed change pressure is normal, walking is OK, but eating soil is weak. This phenomenon is mostly caused by the damage of the overrunning clutch, such as the failure of three compression springs of the overrunning clutch, the fracture of the isolation ring, and the serious wear of the roller working surface of the inner ring cam or outer ring gear. Generally, the parts or the large overrunning clutch assembly should be disassembled and replaced.

④变速压力虽然可以达到正常，但表针摆动﹑不稳，变速泵会出现异响，工作无力或开始正常，过一段时间后就无力，这种故障常发生在更换变速泵或双变总成大修之后。原因是变速泵低压管路出现密封不严，引起大量进气，使变矩器供油不足导致的。

④ Although the variable speed pressure can reach normal, the gauge needle swings and is unstable, and the variable speed pump will make abnormal noise, and its operation will be weak or start to be normal. After a period of time, it will be weak. This fault often occurs after replacing the variable speed pump or overhauling the double transformer assembly. The reason is that the low-pressure pipeline of the transmission pump is not tightly sealed, resulting in a large amount of air intake and insufficient oil supply to the torque converter.

对于矿用装载机而言，如果变速压力是正常的，工作开始还可以，但过一段时间后就无力，并且越加油门车越不走，缓抬油门或停一会后才能走，应该清洗装载机变速箱的油底壳，因由于脏物堵死滤网，使油吸不上来，也有可能会造成这种故障。

For the mine loader, if the speed change pressure is normal, the work can start, but it will be weak after a period of time, and the more the refueling door car does not go, the more slowly lift the accelerator or stop for a while before going. First, clean the oil pan of the gearbox of the loader, because the filter screen is blocked by dirt, so that the oil can not be absorbed, which may also cause this kind of fault.
