Automobile axle shafts may have different problems in different seasons and have the following characteristics:

1. Summer: The temperature in summer is high, and the road surface temperature is also high. The automobile axle shaft is easily affected by high temperature, resulting in thermal expansion and cold contraction, which may lead to problems such as aging of axle shaft bearings, evaporation of lubricating oil and aging of seals. In addition, long-distance and high-speed driving in summer is easy to make the semi-axle transmission system bear a large load, which may lead to the deformation and fracture of the semi-axle.

2. Autumn: In autumn, the temperature gradually decreases, the road surface is wet, and the automobile axle shaft is easily affected by moisture and gas, resulting in problems such as rust and corrosion. In addition, there are many fallen leaves in autumn, which may enter the interior of the semi-axle transmission system and affect the normal work of the semi-axle, so it needs to be cleaned and inspected regularly.

3. Winter: In winter, the temperature is extremely low, the road surface is frozen, and the automobile axle shaft is easily affected by freezing and freezing, resulting in problems such as freezing crack and deformation. In addition, the road conditions in winter are bad, and it is easy to be impacted and bumped when driving, which may cause damage to the semi-axle transmission system. It is necessary to pay attention to maintaining the normal working state of the semi-axle transmission system.

4. Spring: When the temperature rises in spring, the automobile axle shaft may expand and contract due to the temperature change, resulting in the looseness of the axle shaft bearing and the decrease of transmission efficiency. In addition, the road is slippery in spring, which easily causes the semi-axle transmission system to get wet, so it needs to be cleaned and inspected in time to ensure the normal operation of the semi-axle transmission system.

To sum up, automobile axle shafts may have problems such as thermal expansion and cold contraction, rust and corrosion, frost crack and deformation in different seasons, which need timely inspection, maintenance and repair according to seasonal characteristics to ensure the normal operation of axle shaft transmission system and vehicle safety.
