How does air suspension work on a car?
Onboard sensors send information about the ride height of the vehicle to a small computer, which in turn uses that information to tell a pneumatic compressor how much pressurized air to generate. This air is pushed through air hoses and into air springs which use the pressure to regulate the ride height of the vehicle.
How much does it cost to replace air suspensions?
The other option is to replace the original air springs and/or electronic struts or shocks with a conversion kit that includes conventional coil steel springs with ordinary struts or shocks. On a Lexus, the OE air struts list for $950 per wheel!
Why do air suspension coils need to be replaced?
This air is pushed through air hoses and into air springs which use the pressure to regulate the ride height of the vehicle. This creates a smooth, pleasant, ride–as long as they’re working. The main problem with an air suspension is that, like anything made of moving parts, they will eventually wear out.
When did the air suspension replacement industry start?
Since that company’s inception in 1999, the industry has grown from a single company with a small assortment of products to an entire industry, with replacement kits now available for hundreds of vehicle models. So why has the popularity of these kits grown so much in such a short amount of time?
When is it time to replace air suspension?
When owners consider that all air suspension-related expenses are likely to be ongoing for the remainder of the car’s lifetime, replacing an old suspension with one that is brand new makes a great deal of sense in the long run.
How does an air suspension system work in a car?
Additionally, Pro Car Mechanics describes air suspension as a replacement to the leaf suspension or coil spring system with airbags composed of polyurethane and rubber. A compressor inflates the bags to a certain pressure in order to behave like springs.
What kind of springs do air suspensions use?
With an air ride suspension, hollow, inflatable rubber bags (air springs) are used in place of ordinary coil steel springs or leaf springs. The rubber bags are flexible and have a certain amount of give, so they help absorb and dampen bumps to better isolate the suspension from the vehicle’s occupants.
