Description

A shock absorber inflatable closing all-in-one machine

Technical field

The invention relates to the field of dustproofing of shock absorbers, and in particular to an all-in-one shock absorber inflatable closing machine.

Background technique

In today's society, cars have become an indispensable means of transportation in people's lives. With the development of science and technology and the improvement of people's living standards, people have higher and higher requirements for cars. The importance of cars is self-evident. Safety, comfort, energy saving, and environmental protection are the direction and eternal themes of automobile development, which are particularly important today when traffic accidents are increasing in our country, energy is increasingly scarce, and the environment is deteriorating. Electronics, intelligence, electrification, and renewables are effective measures and means to achieve safety, comfort, energy conservation, and environmental protection.

Shock absorbers are used to accelerate the attenuation of vibrations of the frame and body to improve the ride smoothness and comfort of the car. Shock absorbers are installed inside the suspension system of most cars. When a car is driving in a harsh environment, sediment, water, dust and other substances will enter the shock absorber cylinder, which will affect the working performance of the shock absorber and reduce its service life. Such problems can be effectively solved by setting a dust-proof gland, but Due to the addition of a dust-proof gland structure on the shock absorber, the original shock absorber inflation and closing machine will not be applicable to this type of shock absorber.

Therefore, a machine capable of inflating and closing the gland dust-proof inflatable shock absorber has become the key to solving the problem.
