Semi trailer axle maintenance: an important link to ensure transportation safety

As the main force in China's road transportation field, semi-trailers undertake a large number of cargo transportation tasks. As an important component of a semi-trailer, the axle bears the weight of the entire vehicle and various forces during operation. Therefore, regular maintenance of the axle is crucial. This article will introduce the maintenance methods of semi-trailer axles to help car owners ensure transportation safety.

1、 Inspection of the axle

1. Check the appearance of the axle: Check if there are any obvious damages, cracks, or deformations on the appearance of the axle. If there is any abnormality, it should be replaced or repaired immediately.

2. Check the axle oil seal: Check if the axle oil seal is intact. If there is any damage or aging, it should be replaced in a timely manner to prevent lubricating oil leakage.

3. Check the wheel hub bearings: Check if the wheel hub bearings are worn and if the clearance is appropriate. If there are any problems, they should be adjusted or replaced.

4. Check the tires: Check the tire pressure and tread wear to ensure that the tires meet driving requirements.

2、 Cleaning of the axle

1. Clean the axle: Use professional cleaning agents to clean the surface of the axle, removing dirt and oil stains.

2. Clean the wheel hub bearings: Clean the wheel hub bearings, remove impurities and dirt, and ensure smooth operation of the wheel hub bearings.

3、 Lubrication and maintenance

1. Replace lubricating oil: According to the axle user manual, regularly replace the lubricating oil to ensure good lubrication inside the axle.

2. Apply lubricating grease: Apply an appropriate amount of lubricating grease to the hub bearings, ball joints, and other areas to reduce wear and prolong service life.

4、 Fastener inspection

1. Check fasteners: Check whether the bolts and nuts in various parts of the axle are loose. If they are loose, they should be tightened immediately.

2. Torque check: Use a torque wrench to tighten the fasteners according to the specified torque, ensuring that the tightening torque meets the requirements.

5、 Regular maintenance

1. Develop maintenance plan: Based on the usage of the vehicle, establish a reasonable maintenance cycle and conduct regular maintenance.

2. Professional maintenance: Choose a professional repair shop for axle maintenance to ensure the quality of maintenance.

In short, the maintenance of semi-trailer axles is related to vehicle driving safety, reducing failure rates, and extending service life. Car owners should attach great importance to the maintenance of their axles, ensuring that they are always in good condition and contributing to China's road transportation industry.
