What is a nitrogen shock absorber?

Nitrogen shock absorption (inflatable shock absorber) is a special inner wall bypass oil circuit, which can automatically adapt to flat or bumpy roads. The hardness of the shock absorber can be adjusted by adjusting the nitrogen pressure itself, which increases the driver's driving comfort and fun, and also takes into account the safety when driving at high speed.

The advantages of the nitrogen shock absorber are that the compression resilience of the nitrogen shock absorber is adjustable, the toughness is good, and the steering wheel will not bounce;

Because inert gas will not damage the shock absorber because of too high temperature; Change the installation mode of the original car, and the new parts are safer and more reliable; Built-in air storage tank can adapt to various tire sizes by adjusting air pressure (damping); There are many matching vehicles, which can be customized according to the model.

Characteristics of inflatable shock absorber

As a new type of shock absorber, inflatable shock absorber has the following advantages compared with double-acting cylinder shock absorber:

(1) Because of the existence of the floating piston, there is no need for an oil storage cylinder, which reduces a valve system and greatly simplifies the structure; Because of the existence of high pressure nitrogen in the lower chamber, the expansion and compression of nitrogen can be used to compensate the change of cylinder volume caused by the piston rod entering and leaving through the up and down movement of the floating piston.

(2) Under the condition of the same dust cover diameter, the working cylinder and piston diameter of the inflatable shock absorber are large, which can produce greater damping force;

(3) The high-pressure nitrogen in the shock absorber can reduce the high-frequency vibration of the wheel when it encounters the impact force, which is helpful to eliminate the noise;

(4) Inflatable shock absorber eliminates the oil emulsifying phenomenon caused by the existence of floating piston. The disadvantages of inflatable shock absorber are: high requirements for oil seal; The expansion process is complex and difficult to repair; When the cylinder tube is deformed by impact, the shock absorber will not work.
