How to do daily maintenance and maintenance about semitrailer axles?

The semitrailer axles is the core of the core part of the trailer, which is directly related to the load, braking and driving of the traier. If there is a problem with the semitrailer axles, the safety, attendance rate and economic benefits of the vehicle will almost become empty talk. Therefore, it is especially important to do the daily maintenance and maintenance of the semitrailer axles.

If the owner is more familiar with the structure, functions, and various components of the semitrailer axles, daily maintenance and maintenance can be operated by themselves, and even some common small faults can be eliminated by themselves. The time of delivery can also save expenses and costs to a certain extent. However, compared with other parts, flabed trailer the structure of the semitrailer axles is relatively complicated, which has caused a large amount of maintenance to a certain extent. Only with a certain knowledge or technology can this work be better completed.

semitrailer axles daily inspection and maintenance

Before the trailer is running, various safety inspections need to be done to avoid or prohibit failure. The main inspection contents include: tire pressure situation, the tightening of the main bolt nuts of the wheel and suspension system, whether the steel plate spring or the main beam of the suspension system have broken, lighting and braking systems, braking systems and air suspension The system of the system.

Every two weeks or when you encounter frost weather, you need to open the water storage valve at the bottom of the gas storage tube to clean the water.

If it is a new car or a new semitrailer axles, rear dump trailer after the first load is driving, it is necessary to check the bolt nuts of the wheels and suspension systems to ensure that the specified torque can be achieved.

Check the carplasia: After the new car is driving for the first time, or after replacing the wheels, the tightening of the wheel nut/snail cover needs to be checked to ensure that the specified torque is reached.

Method: Remove the nut D, tighten the thread B, install and tighten the nut D.

Check the adjustment arm: It is recommended to adjust the initial installation angle of the arm at 100 ° -105 °, and the best braking angle is 90 °. According to the use of the semitrailer axles, skeleton trailer adjust every 15 days to 30 days, or every 5,000 kilometers-10,000 kilometers.

Method: Pull the adjustment of the arm. If the A value of the push rod on the air chamber is ≥35mm, the semitrailer axles shaft braking gap needs to be adjusted; With the help of the barbar gap of the arm to adjust the nut, adjust the A value to 13%-20%of the length B value of the brake arm.

Check the brake hoof friction tablet: It is recommended to check the thickness and loosening of the braking friction tablet every month or 10,000 kilometers every month. If you find that the thickness of the friction tablet is less than 5-6mm or the loose phenomenon must be replaced. You can observe the hole in the dust cover to check the friction tablet.

Check the brake drum: every 3 months, or check the brake drum regularly according to the semitrailer axles usage. When measuring the inner diameter of the brake drum is less than 422mm or the friction surface continuously cracks, the brake drum should be replaced in time.

Check the wheel bearing gap: The new semitrailer axles must check the wheel bearing gap every three months. Non-new semitrailer axles is recommended to check frequently.
