Problems solved by technology
[0005] 1. It can only fill shock absorbers with regular cavity or wide mouth;
[0006] 2. The shock absorbing fluid filled is wasted, and the production cost is high;
[0007] 3. During the filling process, workers directly contact the shock absorber fluid, which will cause harm to the human body;
[0008] 4. During the filling process, the shock absorber is directly immersed in the shock absorber liquid, and the shell of the product will inevitably cause liquid residue, which will affect the appearance;
[0009] 5. Repeated use of the shock absorber fluid can easily produce impurities. Once the impurities are filled into the shock absorber cavity, it will affect the performance of the shock absorber

Description
technical field [0001] The invention relates to a filling device, in particular to a shock absorber vacuum filling system for a suspension shock absorber. The invention also relates to a vacuum filling method for the shock absorber of the suspension shock absorber. Background technique [0002] As an important part of the automobile suspension system, the automobile engine suspension shock absorber plays a very important role in the comfort, handling, stability and safety of the vehicle. If there are only elastic elements in the car suspension system without shock absorbers, the vibration of the car body will be prolonged for a long time, resulting in deterioration of the car's ride comfort and handling stability. The setting of the shock absorber in the suspension system can reduce the impact load on the relevant parts, reduce wear, improve the economy of use, improve the grounding performance of the tire, suppress the beating of high-speed driving, and improve driving sa...
