Advantages of Air Suspension

• First, light weight

One of the biggest advantages of air suspension is its light weight, which is much lighter than the traditional leaf spring suspension.

• Second, smooth driving

The elastic coefficient of the air spring, that is, the softness and hardness of the spring, can be automatically adjusted according to the needs. When the vehicle is driving at high speed, the air spring becomes harder to improve the stability of the vehicle. When encountering poor road conditions, the air spring becomes softer to improve the comfort of the vehicle. The adjustment of the air spring can also ensure the constant height of the carriage, which is beneficial to protect the safety of the cargo.

• Third, liftable

The liftability is reflected in two aspects. One is that the axle can be lifted through the air suspension, which is beneficial to reduce tire wear and save fuel.
