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.

Air Suspension Function:
1. Aftermarket high Performance Air Suspension Strut Shocks

2. With low noise, friction and long lifespan

3. Reduce the frequency of vibration while driving on the road

4. With an improved design featuring a new Continental air spring bladder

Makes the ride more comfortable and gives the driver more control of ride height

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.

The Advantages of Air Spring
The two front tires bear the majority of braking and steering. Air spring ensures that weight is properly distributed to all four tires for optimal braking and steering. Progressive rate air springs significantly improve ride quality by better absorbing road inputs, while keeping your tires on the road for better handling.
The productive principle of Air spring
Honggu Air Springs are highly durable, precisely engineered and cost-effective for use in a wide variety of actuation and vibration isolation applications. With time-tested designs incorporating fabric-reinforced natural rubber flex-member construction and corrosion-protected end retainers, Air Springs provide superior quality and performance. As actuators, Honggu Air Springs can provide either linear or angular motion.

Hydraulic Shock Absorber

The hydraulic shock absorber provides its dampening action by transferring oil, under pressure, through valves which restrict the oil flow.

The dampening action of a hydraulic shock absorber comes from transferring oil, under pressure, through valves that restrict the oil flow. Resistance to motion is low when the piston moves slowly and high when its velocity is high.
