What Is Air Suspension and Why Does It Matter?

Air suspension systems in vehicles, like those found on certain Ford F-150 models,

Key Components of the Air Suspension System

• Air Springs: These are the core elements. They are flexible air bags that replace the traditional steel springs. Made from durable materials, like reinforced rubber, they inflate and deflate to adjust the vehicle’s height and ride quality. When the air springs are inflated, they lift the vehicle; when deflated, the vehicle lowers.

Air springs are designed to withstand significant pressure and movement. Their design also helps to dampen vibrations and road imperfections, which translates to a more comfortable ride. Regular inspections are vital to ensure they aren’t damaged by wear and tear. A damaged air spring can cause the vehicle to sit unevenly or create ride problems. Air springs come in various sizes and designs depending on the F-150 model and suspension setup. Some use a single air spring per wheel, while others incorporate multiple. Choosing the correct air spring replacement is vital for peak performance.

• Air Compressor: This is the “heart” of the system. It’s a pump that compresses the air and sends it to the air springs. It’s typically an electric pump mounted on the vehicle’s frame. The compressor is powered by the vehicle’s electrical system, usually drawing power from the battery.

The air compressor plays a vital role in maintaining the correct air pressure within the air springs. When the system detects a change in the vehicle’s height or the need for a ride adjustment, the compressor activates to either inflate or deflate the air springs. Compressors are usually designed to be durable, but like any mechanical component, they can experience wear and tear over time. They have filters that prevent contaminants from entering the system, ensuring the air remains clean and the components stay healthy. Failure of the air compressor often results in suspension issues.

• Air Reservoir: Often, air suspension systems use an air reservoir, also called an air tank, to store compressed air. This tank acts as a buffer, supplying air quickly when needed. The reservoir helps the system respond faster to changes in ride height. It reduces the workload on the compressor.

The air reservoir is commonly located in a secure and accessible location on the vehicle’s frame. Its design and capacity vary based on the suspension system’s specifications. The reservoir can store a certain volume of compressed air, ready for immediate use. This is helpful when the system needs to quickly adjust the ride height. An example is when the vehicle goes over a bump, and the air springs must react fast. The tank ensures there’s enough air for these rapid adjustments. Regular checks are helpful to ensure there are no leaks or damage to the tank, which could compromise the suspension system.

• Control Module: The control module, often a computer, is the brain of the air suspension system. It receives inputs from various sensors around the vehicle, processes the data, and then controls the system’s components. The control module makes decisions based on the data to adjust the ride height.

The control module’s programming determines how the air suspension system responds to different driving conditions and driver inputs. It has information about the vehicle’s weight distribution, speed, and terrain. The module uses this info to decide whether to inflate or deflate the air springs to achieve the optimum ride quality and handling. Advanced control modules can offer different driving modes, allowing the driver to select settings that best suit their needs. Diagnosing issues involves using diagnostic tools to read trouble codes stored within the module.
