More and more trucks are equipped with optional or standard gearboxes. While enjoying convenience, transportation people should also learn to use and maintain properly. Next, Jinan automatic transmission maintenance personnel will explain the operation and maintenance of the transmission for you!
注意油面检查
Pay attention to oil level inspection
油面高度应定期进行检查。检查油面高度时汽车应停在水平的路面上。由于热油的体积膨胀，为了防止测量不准，停驶后的车辆不能立刻检查，只有在油面稳定和稍微冷一些时才可进行。
The oil level should be checked regularly. When checking the oil level, the car should be parked on a level road. Due to the volume expansion of hot oil, in order to prevent inaccurate measurement, the vehicle after stopping can not be checked immediately, only when the oil level is stable and slightly cold.
油面高度由变速器壳体侧面的锥形油面观察孔进行检查，油面高度应与油面观察孔下沿平齐。过多的加油量将会导致变速器温度升高和漏油，过少的加油量将会导致零件润滑不良，严重者将会发生烧箱事故。
The oil level height is checked by the conical oil level observation hole on the side of the transmission case. The oil level height should be flush with the lower edge of the oil level observation hole. Too much oil will lead to the temperature rise and oil leakage of the transmission. Too little oil will lead to poor lubrication of the parts, and even a burning accident will occur.
及时补充润滑油
Timely replenish lubricating oil
每款变速箱都有规定的保养周期和换油里程，要根据实际情况进行保养和换油。变速箱内须加注优良重载齿轮润滑油，变速箱的齿轮油规格推荐使用85W-90，寒冷气温下推荐使用75W-90。为了防止不同型号的润滑油发生化学反应，在补充润滑油时应保证与原来的润滑油型号相同。变速器在更换润滑油时，要首先将变速器内原有的润滑油排放干净。
Each transmission has a specified maintenance interval and oil change mileage, which should be maintained and changed according to the actual situation. The gearbox must be filled with excellent heavy-duty gear lubricating oil. 85W-90 is recommended for the gearbox gear oil specification, and 75W-90 is recommended for cold temperatures. In order to prevent chemical reaction of different types of lubricating oil, the lubricating oil shall be replenished with the same type as the original lubricating oil. When changing the lubricating oil of the transmission, the original lubricating oil in the transmission should be drained first.
避开操作误区
Avoid operating errors
当车辆后轮着地，传动系连接的情况下被拖行时，主箱的中间轴齿轮和主轴齿轮并不旋转，而主轴却被后轮带动着高速旋转，这样将会因缺乏润滑而引起变速器的严重损坏。为了防止这类现象发生，应注意以下几点：切勿使车辆在熄火状态下空挡滑行；当车辆需要拖行时，可抽出半轴或脱开传动轴，也可使驱动轮离地拖行。
When the rear wheel of the vehicle touches the ground and is towed with the transmission connected, the intermediate shaft gear and the main shaft gear of the main box do not rotate, but the main shaft is driven by the rear wheel to rotate at high speed, which will cause serious damage to the transmission due to lack of lubrication. In order to prevent this kind of phenomenon, the following points should be paid attention to: Do not let the vehicle slide in neutral gear when the engine is off; When the vehicle needs to be towed, the axle shaft can be pulled out or the drive shaft can be disengaged, and the drive wheel can also be towed off the ground.
The correct and reasonable operation and regular maintenance of the transmission are very important to ensure the safe and reliable driving of the vehicle and extend the life of the transmission. More relevant contents are available on our website http://www.jnbsx.com Ask!
