With the arrival of the severe winter season, the temperature continues to drop, especially in northern China. In recent days, the north wind has been raging, and the temperature continues to fall. Even in sunny weather, it is difficult to resist the biting cold.

For transport vehicles in winter, various parts are more vulnerable than those in other seasons. If you want to ensure the safe and smooth completion of transport operations in cold weather, you must pay attention to daily care and maintenance. Especially the axle, as one of the core power assemblies of semi-trailer, is directly related to the load-bearing, braking and other key functions of the vehicle. Car owners must always check and maintain regularly, and repair problems in time.

So, how to maintain the axle in winter?

1. Before the vehicle runs, pay attention to check whether the external connecting bolts of the axle are loose, whether there is oil leakage, or whether the hub and reducer assembly have abnormal noise. If problems are found, they should be solved before driving on the road.

2. If it is a newly replaced axle, pay attention to the first maintenance, generally between 3000-5000km. The maintenance mainly includes replacement of lubricating oil and gear oil, inspection of front axle toe in, adjustment of braking clearance, inspection of fasteners, etc. The first maintenance is done well, which can largely avoid problems in subsequent use and prolong the service life of the axle.

3. In general, the axle needs a large-scale maintenance every 10000km, including replacing lubricating oil, checking fasteners, checking toe in, checking the wear degree of friction plate, checking reducer assembly and gear oil, etc. if there are problems, replace or repair them in time.

4. In daily use, it shall be transported in strict accordance with the nuclear loading requirements.

5. Don't drive too fast. Don't step on the accelerator and release the clutch pedal sharply to avoid axle deformation, breaking the axle shaft or damaging the gear.

6. Pay attention to the selection of special lubricating oil or gear oil in winter, and often check the bridge head temperature.

Some car owners may say: the axle I bought is maintenance free. Can I avoid frequent maintenance?

Although the maintenance free axle has the characteristics of long maintenance cycle, simple maintenance operation and high operation efficiency, in general, it is not "maintenance free" in the full sense, and there are also mileage restrictions. When the specified mileage is reached, it still needs maintenance, but the maintenance operation is simpler. In addition, the use of axles is closely related to the transportation road conditions, transportation types and transportation frequencies of vehicles. The use and loss of axles of different vehicles are naturally different, so it is difficult to use a unified mileage as a reference. The most important thing is that there is no trivial matter about safety. After all, the axle is an important component related to vehicle safety. It is recommended that car owners do not completely let go, but do a good job in daily inspection.
