Key points of production technology of air shock absorbers


The key points of production technology of automobile air shock absorbers (Air Suspension) mainly include the following aspects:


  1. Material selection:

    - The material of the air spring must have excellent wear resistance and aging resistance, and synthetic rubber and synthetic fiber reinforced materials are commonly used.

    - The outer shell of the shock absorber usually uses high-strength aluminum alloy or steel to ensure the stability and durability of the structure.


  2. Design and manufacturing:

    - The stiffness of the air spring and the shape of the airbag need to be accurately calculated during design to ensure that it can provide stable support under different load conditions.

    - The airbag of the air spring must be strictly sealed to avoid air leakage.

    - The internal structure design of the shock absorber needs to consider the flow characteristics of gas and oil to achieve the best shock absorption effect.


  3. Gas control system:

    - It is necessary to be equipped with a high-precision gas compressor and an electronic control system to adjust the air pressure in the airbag to ensure shock absorption effect and driving comfort.

    - The control system needs to have a real-time monitoring function and can automatically adjust the air pressure according to changes in vehicle load.


  4. Assembly and testing:

    - During the assembly process, all parts must be accurately docked to avoid air leakage or poor shock absorption performance.

    - During the production process, strict testing is required, including pressure testing, durability testing and performance testing, to ensure that the product meets the design specifications and usage requirements.


  5. Maintenance and maintenance:

    - During the production process, it is necessary to ensure the maintainability of the air shock absorber to facilitate subsequent maintenance and repair.

    - Regularly check and replace air springs and other related parts to avoid affecting vehicle performance due to aging or damage.


These points not only affect the performance and life of the shock absorber, but also the safety and comfort of driving.
