How to use ABS system in flatbed semi-trailer?

The sensor installed on the wheel sends a signal that the wheel will be locked. The controller instructs the regulator to reduce the oil pressure of the wheel brake cylinder and reduce the braking torque. After a certain period of time, the original oil pressure is restored. This continuous cycle (up to 5 to 10 times per second) always keeps the wheels in rotation and has the maximum braking torque. For high bed trailer without ABS installed, if you press the brake pedal hard while driving, the wheel speed will decrease rapidly. When the braking force exceeds the friction between the wheel and the ground, the wheel will be locked, and the completely locked wheel will make the tire The friction with the ground decreases. If the front wheels are locked, the driver cannot control the direction of the flatbed trailer. If the rear wheels are locked, the side slip phenomenon is very likely to occur.

Tip: In an emergency, the brake pedal must be pressed to the end to activate the ABS system. At this time, the brake pedal will have some jitter, and sometimes there will be some sound, but it cannot be released, which indicates that the ABS system has started.
1. Ensure that there is no air leakage or lack of air pressure in the brake air circuit of the tractor, and that the tractor has conventional braking.
2. When you maintain the wheel, you should pay attention not to damage the surface of the ring gear. If there is dust or oil on the surface of the ring gear, you need to clean the wheel speed sensor.
3. You should always check whether the sensor connector is loose. If you need to replace it, do not insert it incorrectly. Make sure that the gas path corresponds to the sensor one-to-one.
4. When you apply emergency braking on wet roads, you only need to apply full braking.
5. When installing the wheel, push the sensor to the end first to ensure the gap between the sensor and the ring gear. Be careful when installing the wheel hub, and do not install it brutally.
6. The trailer is equipped with a pipeline filter, which needs to be cleaned once every three months to ensure that the pipeline is clean to prevent damage to the ABS.

Advantage
1. Improve the stability of braking, prevent side slip, tail flick and trailer folding, etc., thus ensuring the safety of the vehicle.
2. The maneuverability of the container platform trailer's steering during braking is improved, the deviation is prevented, and the controllability of the direction during steering is ensured.
3. The braking distance can be shortened on most roads. The higher the speed of the vehicle, the more the distance is shortened (compared to the brake without ABS).
4. It can reduce the excessive wear of the tires when the wheels are locked, and reduce the use cost of the high bed trailer.

The ABS system can make full use of the maximum adhesion between the wheels and the road surface for braking, thereby increasing the braking deceleration and shortening the braking distance, but the most important thing is to ensure the directional stability of the platform trailer.
