1.31 Knowing the parts of a vehicle: Air spring suspension system

A vehicle's suspension system is a crucial element that plays a vital role in how a vehicle handles on the road. Among the various types of suspension systems available, the air spring suspension system holds a special place due to its versatility and ability to provide a smooth and comfortable ride. Let's explore this system in detail.

What is an air spring suspension system?

An air spring suspension system, as the name suggests, uses air instead of traditional steel springs to support the weight of the vehicle. This system consists of a number of components including air bags, air compressors, solenoid valves and an electronic control system that work together to adjust the height and stiffness of the suspension.

Air spring suspension system components

Air pockets

The air bags are the heart of the air spring suspension system. They are made of reinforced rubber and are filled with compressed air. When the vehicle goes over a bump or pothole, the air pockets compress and decompress, absorbing the impact and providing a smooth ride.

Air compressors

The air compressor is responsible for supplying the necessary compressed air to the air bags. It is powered by the vehicle's engine and is controlled by an electronic control system that determines the amount of air needed based on road conditions and vehicle load.

Solenoid valves

The solenoid valves control the flow of air to the air bags. They are electronically actuated and allow the control system to adjust the air pressure in the air bags to alter the height and stiffness of the suspension.

Electronic control system

The electronic control system constantly monitors road conditions and vehicle load and adjusts the air pressure in the air bags accordingly. It also allows the driver to manually adjust suspension height and stiffness to suit their driving preferences.

Advantages of the air spring suspension system

The main advantage of the air spring suspension system is its ability to provide a smooth and comfortable ride. Air bags can absorb impacts much more effectively than steel springs, resulting in less vibrations and bumps being transmitted to the vehicle's cabin.

In addition, the system's ability to adjust suspension height and stiffness allows the vehicle to adapt to a variety of road conditions and loads. This not only improves driving comfort, but also increases safety by improving vehicle stability and control.

Conclusion

In summary, the air spring suspension system is a sophisticated technology that significantly improves driving comfort and safety. Understanding how it works and its components is essential for properly maintaining your vehicle and ensuring its optimal performance.
