Air spring
Air springs have been used in heavy duty vehicle suspension systems
for nearly a century, where they have been able to provide
usefulness by taking advantage of the compressed air required for
vehicle braking systems. Air springs have provided a two-fold
advantage over mechanical leaf- or coil-springs. One advantage with
air suspension is the extra comfort provided by being able to vary
the air pressure inside the spring, which changes the spring rate,
and therefore, ride quality. Additionally, because variable control
over air pressure adjusts the deck or trailer height, aligning
loading docks to the level of the deck is possible when dock plates
are unavailable.
Types of Air Springs
Outside of custom fabricated air springs, there are three available
types of market-ready air springs.
1.Crimped, convoluted bellows, which attach the bellow to the bead
plate by a permanent crimp in the plate. These provide good
vibration isolation and linear/angular actuation, but are not for
vehicle suspensions.
2.Sleeve bellows, which attach the bellows to the bead plate by an
external clamp. This air spring type provides good vibration
isolation, but only linear actuation. They are not typical in
suspensions.
3. Rolling lobe bellows, which incorporate a piston at one end of
the bellows, rather than a bead plate. This is most commonly found
in vehicle suspensions, and is generally not recommended for
vibration isolation.
Air Springs Information.
Air springs contain a column of air in an elastomeric bellow or
sleeve to provide suspension, isolation, or actuation. Commonly
found in vehicle suspension systems, occasionally in conjunction
with a coil spring, they are also used to insulate vibration in
machinery and as linear or angular actuators.
Air Springs Benefits.
1. Constructed with high quality material
2. Professional auto part
3. Easy to use, saves time and money
4. Security and durability
5. Compact design
6. Long time to utilize
Air Suspension
When it comes to air-ride suspension, they come in several styles
for both OE replacement and aftermarket upgrades. Some systems use
an integrated air spring and shock absorber that replaces your
customer’s metal springs with pressure-adjustable air springs
(i.e., airbag). Using correctly sized air springs and properly
calibrated shock absorbers offers ride characteristics similar to
coilovers.
An air-suspension system consists of many different components.
Components include an air compressor, air springs, pneumatic
solenoid valves, height sensors, electronic control unit, air
reservoir, air lines, pressure sensor and temperature sensor. The
system may be designed for the rear air suspension only or for the
entire vehicle.
While air-suspension systems are mostly used on high-end European
cars, manufacturers have adapted them to many other vehicles such
as SUVs and pickups to improve ride comfort and functionality. OEMs
also discovered that air ride could improve fuel economy by
lowering the car at highway speeds to reduce the drag coefficient.
How do air struts work?
An air suspension system is a style of vehicle suspension that's
powered by an electric pump or compressor that pumps air into
flexible bellows that are typically made out of a
textile-reinforced type of rubber. ... A compressor inflates the
bags to a certain pressure in order to behave like springs.
