As an important part of automobile transmission system, the sales of automobile semi-axle are affected by seasons. The main reasons are as follows:

1. Seasonal demand: the sales of automobile half shafts are affected by seasonal demand. For example, in cold areas in winter, due to the influence of road icing and snow, vehicles are prone to slip and sideslip, which leads to the axle shaft being easily damaged. Therefore, there may be more demand for axle shaft maintenance and replacement in winter, thus promoting the increase of axle shaft sales.

2. Maintenance requirements: The automobile axle shaft is one of the easily worn parts in the vehicle transmission system and needs regular maintenance and replacement. In some seasonal maintenance peaks, such as spring and autumn, car owners may pay more attention to the maintenance of vehicles, including the inspection and replacement of axle shafts, thus driving the sales of axle shafts to increase.

3. Vehicle adaptation requirements: different seasons have different requirements for vehicle performance and handling, and some car owners may replace suitable axle products according to seasonal requirements to improve vehicle performance and safety. For example, axle shaft products with higher temperature resistance may be needed in summer, while axle shaft products with lower temperature resistance and skid resistance may be needed in winter.

To sum up, the sales of automobile semi-axle are affected by seasons, mainly due to seasonal demand, maintenance demand and vehicle adaptation demand. Therefore, automobile semi-axle manufacturers and sellers need to flexibly adjust their production and sales strategies according to seasonal changes and market demand to meet the needs of consumers and enhance the competitiveness of products.
