Air Suspension Spring

An air spring is a rubber and fabric bladder that holds air pressure to support a load and isolate passengers and cargo from the shock of motion caused by road irregularities. As the air pressure increases, the air spring can support more load while the spring rate increases. The larger the air spring, the greater the maximum load it can support.

Air Suspension Spring composition

1. Air fitting: A tapped hole allowing for the spring to be fed from the air compressor
2. Nut/bolt/mount: The method for attaching the air spring to the component. Some air springs incorporate a bolt and air fitting combination device.
3..Bead plate: Crimped metal plate enclosing the spring and allowing attachment. This is typically forged steel, cast zinc alloy or cast aluminum.
4. Bellows: The physical, multi-layer material withholding the compressed gas. Usually made of neoprene or rubber.
5. Girdle: Only found in air springs of convoluted design, separating the bellows chambers.

6. Bumper: An optional layer of padding protecting the piston from damage if the air spring fails.

7. Piston: The component attached to the machinery requiring suspension, which is in turn supported by the enclosed air. The piston housing is typically attached with further hardware.

Air Suspension Spring Benefits

1.Reduce Poor Braking and Steering
Front tires account for the majority of braking and steering. Air springs ensure that weight is properly distributed to all four tires for optimal braking and steering.
2.Eliminate Poor Headlight Aim
Your headlights should be on the road and not in the trees. Only level and stable vehicles provide safe and proper headlight aiming—critical for safe night driving.
3.Reduce Trailer Sway
There is nothing worse than feeling your whole vehicle or trailer sway with one strong burst of wind. When towing a trailer, air springs permit precise tow-vehicle-to-trailer-height adjustment for exact alignment, virtually eliminating trailer sway no matter the weather.
4.Eliminate Rough Ride
Progressive rate air springs significantly improving ride quality by better absorbing road inputs, while keeping your tires on the road for better handling.
5.Reduce Body Roll
The increased spring rate from air springs vastly improves vehicle stability especially in cross winds and emergency maneuvers. Less body roll can increase driver confidence of high center of gravity vehicles in less than ideal conditions.
6.Eliminate Bottoming Out
Worried about bottoming out on road bumps and driveways? Air springs restore normal ride height when heavily loaded or towing, reducing suspension wear and eliminating crashing on bumps.

Air Suspension Spring Work

Air spring, in technology, elastic machine component able to deflect under load in a prescribed manner and to recover its initial shape when unloaded. The combination of force and displacement in a deflected spring is energy, which may be stored when moving loads are being arrested or when the spring is wound up for use as a power source.

Air Suspension Spring Features And Function

1. An adjustable configuration allows the user to fine tune desired damping, either continuously or at discrete settings.
2. A reducible gas spring has an adjustment style for gas shocks in which gas is let out to permanently reduce force capacity.
3. In a locking gas spring the position can be locked at ends or in the middle of stroke.

4. Valves can be included for fluid absorbers, a valve or port, which can be used to increase or decrease fluid volume or pressure.

About Us

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 Wingprene or natural rubber flex-member construction and corrosion-protected end retainers, HONGGU Air Springs provide superior quality and performance. As actuators, they can provide either linear or angular motion.

These air bag products offer a favorable stroke-to-compressed-height ratio when compared to air cylinders, and they can accept a wide variety of actuation media such as air, water, nitrogen or anti-freeze. As isolators, they are effective in reducing the harmful effects of vibration. They also can simultaneously isolate vibration and regulate load height as well as allow for consistent vibration isolation under varying loads.

HONGGU supplies air springs for the majority of all light vehicles based on air suspension systems, making us one of the leading global air spring manufacturers.

Our products and technologies can be delivered separately or as a unit with the damper. The HONGGU portfolio ranges from front and rear axle air springs, to switchable multi-chamber air springs Our comprehensive air springs know how makes us a reliable and trusted component and module supplier for air spring applications of all sorts.

The key element in air springs for light vehicles are the rubber bellows. These essentially determine the comfort and service life properties. HONGGU offers three different types of bellows – axial, cross-ply – which differ in terms of the structure of their embedded reinforcing fibers.

In an axial sleeve, the fibers embedded in the elastomer run axially to the deflection direction. The cross-ply bellows has two layers of reinforcing elements, placed at an angle to each other. Unlike in a fabric, these elements are not connected. The cross-axial bellows, combines the great torsion decoupling capability of an axial sleeve with the dimensional stability of a cross-ply bellows.
