Pneumatic shock absorbers, as the name suggests, are shock absorbers that control the height of the car through air pressure. The working principle of pneumatic damping is to change the height of the car by controlling the air pressure, including elastic rubber airbag shock absorber, air pressure control system, trunk gas storage tank and electronic control system. Many riders are limited to the mechanical adjustment and road condition of the twisted teeth suspension. They can't make their car in perfect posture anytime and anywhere. Then the pneumatic shock absorber is a gospel. In fact, the pneumatic shock absorber is not only found in the modified car. Many of the original models are also equipped with pneumatic shock absorbers such as JEEP Grand Cherokee, Land Rover discovery, and even many super-running original factories will have pneumatic suspension.

The modification of the pneumatic suspension is divided into two parts according to the function, one part is the shock absorber (including the airbag), and the other part is the controller.
Shock absorber
Regarding the modification of the shock absorber, there are three methods that are common in the market. The first one is a relatively cost-effective modification scheme. The pneumatic suspension is upgraded directly on the original shock absorber barrel. In short, it is directly replaced. The spring of the factory is a gas bag, because it is a later modification, so there are some problems here.
The first is the quality assurance of the original factory upgrade, the original factory upgrade according to the feedback from my friends, the probability of problems is relatively large, pneumatic shock is a precision modification, especially the seal is directly related to the stability after the modification, and then the domestic The quality of the air bag, first of all, does not say how long the warranty and the efficiency of the warranty. It’s just that we are driving on the road. Once quality problems occur, the danger of airbag damage is fatal. Of course, this is not absolute. It is also limited to the technical level of the conversion technician. If the level of the refit technician in your city is trustworthy, it is also a method. This method is limited by the model and some models cannot be upgraded.

The second method is actually the evolution of many twisted-tooth players. Many players choose extreme posture play after changing the twisted teeth suspension. If you buy the brand pneumatic shock absorber directly, the previously purchased twisted teeth suspension will be wasted. It is. Speaking of this, many riders may already know that the second method is to change the airbag with a twisted barrel. Replace the spring part of the suspension with the airbag.
The third type is relatively simple and reliable. When the brand shock absorber body is purchased, the brand shock absorber body is already a set of shock absorber body, so the sealing is reliable, of course, the price is relatively expensive. Look at personal preferences and purchasing power.

Control System
The control system is also very diverse in the market. With the well-known pneumatic suspension, the control system is no longer so mysterious. The simple classification is the air pump, solenoid valve, control unit and gas tank. There are many types and brands depending on the function, which can be roughly divided into the following categories:
The first type is the most basic in-vehicle control (controlled by buttons installed in the car), and the lift is lowered before the front rises, then rises and then falls.
The second is to add a remote control system to the basic version, which can realize remote control lifting. Of course, it is only before the front rises, then rises and then falls.
The third kind of comparison is higher than the high-end atmosphere. On the basis of remote control, four-wheel independent lifting can be realized with memory. The memory system mentioned here can be converted into the height of the vehicle body according to the value of the memory pressure.
The above three are based on the value of the air pressure to determine the height of the car body, so it is necessary to install a barometer after the above three installations, but the installation of the barometer also needs to pay attention to the seal.
The fourth type uses mechanical memory, which uses the height sensor to memorize the height of the car body to achieve high body memory. This method is very user-friendly because if it is barometric memory, we assume that the value of the rear wheel's air pressure is normal. 80, then in the case of the back seat full, the value will rise to 90-100. However, the height of the rear wheel of the vehicle body is rather reduced, which causes the bottoming of the vehicle and the squeezing of the fenders or linings caused by the misunderstanding of the height.

Mechanical memory does not cause this to happen, because he always remembers the height of the car body, so when the weight of our car body changes, the solenoid valve will increase the air pressure according to the feedback of the computer, so that the car body height is maintained. In the memory mode. This method of memory is not only useful for the situation where the height of the car body changes, even when we are turning, but the body is also involved in the roll, and the body is kept at a normal level by supplementing the pressure of the roll. Of course, we can also set the sensitivity according to the habits used.
Some brand controllers also design WIFI module, which can realize mobile phone software control (i LEVEL), which can realize memory and four-wheel independent lifting adjustment in vehicle ignition state, and realize memory height adjustment in the flameout state, which is convenient for riders. The height of the vehicle is adjusted outside the car.
