At present, the new national standard gb7258-2017 has been implemented for two years. Many Trailer drivers in China still want the combination of drum brake and rigid suspension. However, the era of reckless development of the domestic road transportation industry has passed. Now the state has made great efforts to control overload, mainly for road traffic safety. The higher configuration of vehicles can also ensure the safety of drivers.

Due to the implementation of the new rules, lightweight and disc axle + air suspension have become the standard configuration of most trailers. The reason why we vigorously promote the high configuration of trailers and implement the disc axle + air suspension combination is, on the one hand, the continuous progress of China's manufacturing technology, which has been able to meet the high specification requirements of vehicles in our highway transportation, and on the other hand, to improve the transportation efficiency and safety of vehicles.

The most obvious difference between disc brake axle and drum axle is the difference of brake structure. The brake pads of disc axle are open, and the brake of drum axle is in a closed space, so the heat dissipation is far inferior to that of disc axle. Here are some advantages of the disc axle:

1. Good heat dissipation of brake.

2. Sufficient braking force, linear braking, combined with ABS system, can greatly improve the braking performance of the vehicle.

3. The left and right braking forces of the wheels are uniform, and there will be no tire eating.

4. The brake system is sensitive and allows drivers to make braking action calmly.

These advantages of disc axle can be said to be the focus of attention of drivers, which can effectively improve the safety of vehicle driving and enable drivers to focus more on vehicle driving.

Air suspension system is widely used in the market under the promotion of market demand and policy guidance. The mass of air suspension system is much lighter than that of rigid suspension. On average, each suspension is about 100kg lighter. Air suspension has many advantages. Let's list them below:

1. Light weight. The biggest advantage of air suspension compared with plate suspension is that it is much lighter.

2. The vehicle runs smoothly, and the small ditch and ridge can hardly be felt. The lightweight body and air suspension can be called a golden combination.

3. It is economical, fuel-efficient and convenient for loading and unloading. Generally, the air suspension system can adjust the vehicle height and lifting axle, and adjust the height of the cargo platform to facilitate loading and unloading. The lifting axle can reduce the number of wheels, reduce tire wear and achieve the purpose of fuel saving.

4. The safety is high, the air suspension is stressed evenly, and the air bag can automatically adjust the height to improve the stability of the trailer.

After reading the above points, do you think the combination of air suspension and disc axle is very perfect, which can not only greatly improve the safety of the vehicle, but also improve the transportation efficiency of the vehicle and the economic benefit of the trailer.
