Why We Choose Semi Trailers with Air Suspension?

The suspension types for semi trailers include air suspension and mechanical suspension. Typically, trailers are equipped with mechanical suspension in combination with leaf springs. However, air suspension offers better cushioning force and is mainly used in transporting precision instruments, hazardous chemicals, and the like.

Let's look at the structure of air suspension first. It mainly consists of a front support frame, a rear support frame, a spring beam, a spring beam shaft, an air spring, a shock absorber, and a U-bolt. The air spring is the core part of the air suspension for semi trailers, and its performance directly determines that of the suspension. The upper end of the air spring connects to the semi-trailer frame, and the lower end connects to the spring beam.

Now, what advantages do semi trailers with air suspension have?

1. Superior shock absorption: Compared with the traditional mechanical spring, the air bag is softer and more comfortable. It creates a soft connection between the trailer frame and the axle, greatly reducing the impact from the road surface. This not only improves driving comfort but also protects the cargo.

2. Reduced load stress: The compressibility of air allows the airbag suspension to handle road undulations easily, decreasing the load pressure and extending the service life of the axle and trailer, thus reducing usage costs.

3. Lighter weight: Lightweight is a trend in the trailer accessories industry. Air suspension is lighter than traditional suspension, providing more weight allowance for standard load users and saving fuel for no-load users.

4. Longer service life: Due to the light weight of the air spring and low friction of the air inside the bag, the service life of air suspension can be 2 - 3 times that of traditional suspension, helping owners save costs.

In conclusion, choosing semi trailers with air suspension is a comprehensive consideration based on various factors like superior performance, enhanced safety, and long-term cost savings. It meets the specific transportation needs of different cargos and aligns with the modern trend of the transportation industry towards efficiency, comfort, and sustainability.
