In recent years, the popularity of air suspension has continued to rise, especially with the enforcement of regulations, making the legendary "high-end accessories" more and more widely used in the freight industry. Unlike traditional leaf springs, air suspension uses air springs, which support the vehicle body through the pressure of gas, thus possessing many advantages that leaf spring suspension cannot achieve.

Inventory of the Advantages of Air Suspension

1. Lighter self weight

The air suspension uses compressed gas as the elastic medium, which has a significant advantage in self weight compared to traditional steel structures. The lighter weight of the vehicle means it can carry more cargo, and it can also improve fuel economy and reduce comprehensive vehicle costs.

2. Excellent shock absorption effect

Compressed air isolation has a better effect than leaf springs, which can greatly absorb bumps and impacts from the road surface. It can improve driving comfort and enhance the protection of goods, ensuring a constant height of the cargo compartment as much as possible, and reducing or avoiding cargo damage caused by bumps.

3. Height can be freely adjusted

Air suspension can achieve the lifting and lowering of a single axle or the entire vehicle. When the vehicle is empty, it can lift the single axle, reduce tire wear, and save fuel; When the vehicle is loaded on different pallets, the air suspension can adjust the body height to match different pallets, making it easier to load and unload goods.

4. Reduce tire wear and tear

The connection between the air suspension and the wheels and frame is a soft connection. When the vehicle encounters poor road conditions, the adhesion between the tires and the road surface is softer, which is more conducive to reducing tire wear and saving the cost of tire replacement.

5. Protecting chassis components

The impact and bumps from the road surface are reduced, and the loosening of fasteners on the vehicle chassis is greatly reduced. The service life of chassis components can also be extended to a certain extent.

It can be said that air suspension almost meets all the requirements of car owners for lightweight, reliability, smoothness, cost reduction and efficiency improvement. Many car owners who have used air suspension praise it, and even directly refer to it as a "transportation artifact".

Indeed, air suspension has played an extremely excellent role in the transportation of hazardous chemicals, flowers, fruits and vegetables, cold chain goods, electronic instruments, express delivery, fragile and vulnerable goods, etc. However, if we consider it as a "transportation artifact", it may bring some biased colors. After all, any approach to discussing performance regardless of actual usage conditions is meaningless, and air suspension is not entirely flawed.

Compared to traditional leaf spring suspensions, air suspensions do not have advantages in strength, durability, resistance to construction, and load-bearing capacity. Although many manufacturers are promoting the use of air suspensions in transportation fields such as coal, gravel, wood, and steel coils, these goods can even be crushed on asphalt roads during transportation. How much can the airbags of air suspensions bear? Especially when climbing, downhill, or passing through bumpy roads, can the air suspension be fully competent? I'm afraid this is not just a 'applicable' sentence that can convince the audience, but also needs to be expressed in terms of actual market usage data.

So, air suspension is good and reliable, but the premise is to combine it with actual usage conditions. If the road conditions are often heavy or poor, and the transported goods have no or no high requirements for damage, then ordinary leaf spring suspension is sufficient and the price is also cheap.

Of course, the technological level of vehicles and accessories has developed rapidly. With continuous improvement and improvement, it is unknown that air suspension may gradually overcome its own shortcomings. In addition, in recent years, relevant departments have made significant efforts to promote air suspension, and the management of overloading and exceeding limits has also been increasing. It may also be necessary to wait and see whether air suspension can fully occupy the usage space of leaf spring suspension after overloading and exceeding limits have withdrawn from the historical stage.
