With the advent of severe winter, low temperature weather is easy to cause various vehicle faults, which has brought a severe test to vehicle driving. As the saying goes, "three points are in repair and seven points are in maintenance". If the preparations for the winter are not done well, it will bring all kinds of faults and even affect the driving safety. Do a good job in the maintenance of semi-trailer to ensure its stable operation in winter.

How to maintain the braking system of semi-trailer in winter?

1. Check the air circuit connector

In winter, the temperature is low and the sealing ring or cushion is relatively hard, which is easy to cause the contraction of the sealing pipe joint. Therefore, before leaving the car in the morning, be sure to check the sealing of each joint of the gas circuit. It is best to touch one by one, tighten it in time or reinstall it.

2. Check the drying tank of the main vehicle

Check the dryer tank of the main vehicle to ensure that the air source of the main vehicle is dry and free of moisture. As the drying tank is an air filter, the longer it is used, the easier it is to lose the filtering effect on the residual water vapor of compressed air, resulting in water accumulation and icing in the pipeline and valve body, affecting the normal use of the brake.

3. Drain the accumulated water regularly from the main and hanging gears

In winter, the temperature is mostly below zero, and the gas is easy to produce water droplets. Therefore, the air reservoir of the main vehicle and trailer needs to discharge water regularly to ensure the dry gas used for braking. If the water is not drained in time, the humid gas inside the air reservoir is easy to enter the valve body. When the temperature is lower than zero, it will freeze, resulting in piston jamming and affecting the braking performance.

4. ABS maintenance

ABS is connected with multiple sensor connectors, which is used to transmit the braking system signal and make the ABS system give full play to the best braking force and frequency. Therefore, it is necessary to check and maintain each sensor connector. At the same time, the ABS gear ring shall be removed and cleaned regularly to ensure that the sensing signal between the gear ring and the probe is good and the joint is free of putty.

In order to ensure the stable braking performance of the trailer, in addition to the daily maintenance and repair of the braking system, it is also very important to select an axle with qualified quality and stable performance. The more high-quality axle, the more sensitive and reliable its braking performance, which can provide guarantee for driving safety in severe cold weather.
