What is an air suspension? How does it work?

The air suspension systems are the recent replacements to the older spring suspension systems. Their power source can be electric or can be an engine driven compressor or an air pump. The compressor pumps the high-pressure air to the strong and flexible bellows. These bellows are usually made up of textile-reinforced rubber. The air at high pressure expands the bellows and helps in raising the chassis from the axle.

The air suspension system has greater advantages over the conventional suspension systems. It offers instant tuning, better handling in variable situations and varying load capacities. It absorbs and direct road force and helps in maintain the rebound, jounce and wheel oscillations.

Working mechanism of the air suspension

The air suspension system starts with the onboard air compressor which gets power from the electrical system of the car and enables inflammation of each bag. The Compressor feeds high-pressure air to each spring by using either polyurethane pipes or stainless steel tubes.

Many of the times, people get a separate tank which helps in maintaining the instant pressure within the system. This can allow smoother transitions during large pressure changes. This component can be inbuilt or one can even customize it as per the requirements.

In the air suspension, the compressor operates like any other pumps. It draws external air in the storage tank, compresses it to high pressure and delivers it to the other end. With the integration of controller, it guides the system about when to pump the air and what quantity of air is necessary. Such controllers can be manual or electrical in nature.
