Have you ever felt that the brakes of your trailer are not working well for a moment, and then you c......
Have you ever felt that the brakes of your trailer are not working well for a moment, and then you constantly replace the brake pads or brake drums, and many card users replace the pump valves, but the effect is not very good. So what is the problem? This is actually related to the consistency and matching of your main braking system.
So how should the main hitch be matched to make the braking system more effective and safe?
The matching of main gear affects the braking safety! What should I choose?
▎ do not refit or disassemble the front wheel brake without permission
Before talking about the matching of main gears, the first premise is to ensure that all braking systems of your vehicle can work normally, including but not limited to air circuit, ABS, etc. Some of our trucks like to release the front wheel brake because they think that the front wheel brake will cause head pushing and accidents. It's better to remove it directly. Is that true?

Many misconceptions believe that ABS will increase the braking distance. I feel that the wheels will not lock up after ABS, which will indirectly lead to the increase of braking distance. Therefore, in order to pursue the feeling of wheel locking under one foot braking, some card users do not use ABS directly, and do not plug in the ABS cable when connecting the trailer.

Dangerous operation! The front axle brakes have been removed
When ABS is not used, the front wheels of the main car will lock up, and the head will be pushed. Therefore, the front wheel brake will be directly released. Or in order to pursue braking sensitivity, some card users have replaced products such as brake king, which also has a certain impact on the braking system of the whole vehicle, such as delay in braking clearance, early scrapping of brake drum, etc.
▎ the existing control system shall not be less than the main vehicle equipped with EBs. Additional attention shall be paid

Let's talk about the main coupling matching under the condition that the braking system works normally. The first is the most basic configuration. The main Trailer must have an ABS braking system. In addition, the height of the main vehicle and the trailer must comply with the design standard (generally, the height of the trailer tail is slightly lower than the height of the main vehicle (front). Otherwise, the friction between the wheels and the ground will be affected during braking.

In addition, in view of the increasingly high configuration of the main vehicle, the configuration of the trailer should also keep up with it. The most obvious one is the EBS braking system. Now more and more main cars are equipped with EBS system, but it seems that people do not realize that the main car EBS should be matched with the trailer EBS, so as to give full play to the best effect.

If the main vehicle is EBs and the trailer is ordinary ABS, the problem of braking consistency will certainly occur during braking. EBS is controlled by electric signal, so the braking response will be faster. If the trailer is an ordinary ABS, it is very likely that the main vehicle will respond first when braking, and the trailer will respond late or slowly, so the head may be pushed.

In addition, if the main vehicle has EBs and the trailer has no EBS, it is very likely that the trailer will overturn the main vehicle when the turning speed is too fast. The reason is that in order to ensure the safety of the main vehicle when turning at high speed, the EBS system will be used to automatically brake the wheels on the inside of the vehicle. However, the trailer has no EBs and cannot synchronize the action of the main vehicle, which will push the main vehicle forward, resulting in rollover.

EBS cable interface is 7-core cable
Therefore, if the main vehicle has EBS, the trailer should also be equipped with EBS, which can not only improve the braking comfort, but also improve the cornering stability. In addition, the new national standard requires air suspension and disc brake. If EBS is equipped, it can not only improve the braking response, but also realize some additional functions, such as tire pressure monitoring, weighing, etc.
▎ domestic car enterprises should strengthen the matching of main and Trailer
The main hook matching seems very simple, but it is a systematic work. A small configuration change will cause a chain reaction. In fact, the tractor enterprises should take the lead to strengthen the matching of main gears, so as to give full play to the performance of the tractor.

For example, the ultra-low wind resistance proposed by heavy truck Yellow River actually means that the main vehicle and trailer are matched according to the design of ultra-low wind resistance, and the ultra-low wind resistance design can be realized finally. If it is matched with other trailers, it is difficult to achieve such a low wind resistance without professional calibration and matching. No matter how excellent the front design is, it is also necessary to match with a suitable Trailer.
In addition, in terms of braking consistency, if the main vehicle company has done the main vehicle matching experiment and calibration, the user can configure or calibrate according to the standard after purchasing, so that the braking system performance can be brought into full play. Including some safety configurations of the main vehicle, such as AEB, LDWS, etc., are actually closely related to the trailer, which requires the main vehicle enterprise to complete the matching work.
● postscript
The matching of main gears has a great impact on our safety, fuel economy and comfort. In order to ensure safety, the braking system must work normally and correctly match various electrical systems between the main vehicle and the trailer. In particular, the main vehicle and trailer of EBS should also be matched with EBS system, so as to give full play to the performance.
