Air Suspension System

As the car's suspension system is an often-overlooked area. From a comfort and safety standpoint, your car's suspension is integral to how your car drives. Shock absorbers and coil springs help absorb and direct road force, maintaining wheel oscillation, jounce and rebound.
However, every time you add or take away weight to a vehicle, speed up or slow down, or turn left or right, this challenges what the shock absorbers and springs are capable of. Traditional stock shocks and springs are designed and installed with only a fixed set of situations in mind.
Honggu Air suspension systems essentially replace a vehicle's coil springs with air springs. The air springs are simply tough rubber and plastic bags inflated to a certain pressure and height to mimic the coil springs. But the similarities end there. By adding in an on-board air compressor, sensors and electronic controls, today's air suspension systems provide several advantages over all-metal, conventional springs, including near-instant tuning, and the ability to adapt handling to different situations and vary load capability.
Whether the system is manual or electronic, or installed by a weekend mechanic or a seasoned tech, air suspension can lower a car to improve its street cred, even out a heavy payload, or simply improve the ride of a vintage Detroit metal street monster.

Auto Parts Air Suspension Features:

1. Eliminate the vibration of the axle and wheels caused by the road surface, ensure that the wheels grip the ground at any time,
thereby ensuring the steering and braking functions of the vehicle and improving the safety of the vehicle.
2. To prevent the heavy vehicles from damaging other parts.
3. The off-road performance of the vehicle can be improved even in extreme weather, and the noise is low, the friction is small, and the service life is long.

A strut is a major structural part of a suspension. It takes the place of the upper control arm and upper ball joint used in conventional suspensions. Because of its design, a strut is lighter and takes up less space than the shock absorbers in conventional suspension systems.

Auto Parts Air Struts

A struts perform two main jobs. First, struts perform a damping function. A piston is attached to the end of the piston rod and works against hydraulic fluid to control spring and suspension movement. Just like shock absorbers, the valving generates resistance to forces created by the up and down motion of the suspension. Also like shock absorbers, a strut is velocity sensitive, so that the amount of resistance can increase or decrease depending on how fast the suspension moves.
A struts also perform a second job. Unlike shock absorbers, struts provide structural support for the vehicle suspension, support the spring, and hold the tire in an aligned position. Additionally, they bear much of the side load placed on the vehicle's suspension. As a result, struts affect riding comfort and handling as well as vehicle control, braking, steering, wheel alignment and wear on other suspension.

Shock absorbers and how they work
The shock absorbers reduce and slow down the vibrations from the springs, which is why technically they are correctly referred to as vibration dampers. Vibration dampers convert kinetic energy into thermal energy through fluid friction. This involves the flow of oil being slowed down by the valve passages inside the damper.

How do you take care of air suspension?

1.To help you better take care of your vehicle, here are the top five tips for maintaining your car's air suspension system.
2.Check System for Leaks.
3.Check Air Line Connections.
4.Check the Air Springs.
5.Perform Visual Inspections and Clean Regularly.
6.Schedule Routine Service Appointments.
