1.17 Knowing the parts of a vehicle: Air suspension system

The suspension system is a crucial component of the vehicle, responsible for ensuring comfort, stability and safety during transit. There are several types of suspension systems, but one of the most advanced and effective is the air suspension system. This system is often found in heavy vehicles such as buses and trucks, but it can also be installed in passenger cars to improve performance and driving comfort.

What is the air suspension system?

The air suspension system is a type of suspension that uses compressed air instead of springs to support the weight of the vehicle. This system consists of air bags, a compressor, control valves and sensors that monitor and adjust air pressure to keep the vehicle level and stable.

How does the air suspension system work?

The operation of the air suspension system is quite simple. The compressor, which is powered by the vehicle's engine, compresses the air and stores it in a reservoir. When the vehicle needs more support, such as when carrying extra weight or going over rough terrain, the control valves release air from the air pockets. This increases air pressure, raising the vehicle and providing a smoother ride. When the extra support is no longer needed, the valves release air from the bags, lowering the pressure and lowering the vehicle.

What are the benefits of the air suspension system?

There are many benefits to using an air suspension system. First, it offers a smoother, more comfortable ride as air is a natural shock absorber. This means the vehicle can travel over rough terrain and bumpy roads without causing discomfort to passengers.

Secondly, the air suspension system is highly adjustable. This means you can adjust the air pressure to suit road conditions and vehicle load. This is especially useful for vehicles that carry heavy loads, such as trucks and buses.

Thirdly, the air suspension system can improve fuel efficiency. As the system can adjust the height of the vehicle, it can reduce air resistance and improve aerodynamics, which can lead to better fuel economy.

Maintenance of the air suspension system

Like any other vehicle component, the air suspension system requires regular maintenance to ensure its proper functioning. This includes regularly checking the air pressure in the bags, inspecting the compressor and control valves for any signs of wear or damage, and replacing any faulty components.

Also, it is important to remember that although the air suspension system is more durable and reliable than traditional suspension systems, it can still fail if not properly maintained. Therefore, it is essential that you follow the vehicle manufacturer's recommended maintenance schedule.

In conclusion, the air suspension system is an important part of the vehicle that offers many benefits. However, to ensure you get the most out of these benefits, it's important to understand how the system works and how to maintain it properly.
