An air bag on a car is an element of the body suspension, a more modern alternative to a metal spring.
It serves to eliminate vibrations that occur during the movement of the car and soften the loads transmitted from the load to the frame or body of the car. It is also known as an air spring, air cylinder, air shock absorber.(//tractor-service.com)

In addition, the following advantages can be noted:
1. Less impact load on the road surface - asphalt is less destroyed. The same applies to the wheels and the frame of the truck.
2. A large range of goods that can be transported. Transported values are in a more careful position.
3. Less fuel consumption. Sometimes it is not obvious, but in most cases it is an undeniable fact.
4. Ease of adjusting the height of the suspension, its stiffness and load limitations.
5. A large range of goods that can be transported. Transported valuables are in a more careful position.
