Airbag shock absorber: The innovator of shock absorption technology

The core of the airbag shock absorber lies in using the compressibility of gas to achieve the shock absorption function. Different from traditional spring shock absorption or hydraulic shock absorption, it mainly relies on the high-pressure gas filled inside to absorb and disperse vibration energy. When subjected to vibration or impact, the airbag will undergo elastic deformation, and the air pressure in the air chamber will change accordingly. If the air pressure is too high, the valve in the air chamber will automatically open to release some pressure, reducing the deformation of the airbag and thus reducing the vibration transmission. When the air pressure is too low, the valve closes, the pressure in the air chamber recovers, and the airbag also returns to its original state, continuously exerting the shock absorption function.
Taking the airbag shock absorber of a car as an example, it also has some special functional mechanisms. On the one hand, it performs well in alleviating the volume change of the hydraulic chamber caused by the movement of the inner rod. Since liquids are incompressible, ordinary civilian vehicle shock absorbers adapt to the volume change by retaining some gas, but during intense movement, it is easy for the hydraulic oil to produce bubbles, affecting the shock absorption effect. The airbag shock absorber adapts to the volume change through the contraction of the airbag, and at the same time, realizes the separation of oil and gas, avoiding the generation of bubbles. On the other hand, it can effectively prevent idle stroke. Without an airbag, when the shock absorber is compressed rapidly, a vacuum may be generated under the piston. During the rebound, this part of the stroke has no damping, affecting the shock absorption effect. However, the airbag shock absorber increases the air pressure in the hydraulic chamber by filling high-pressure gas, avoiding the occurrence of the "idle stroke" of the vacuum and improving the shock absorption performance.

 

Automotive Industry
In the automotive field, airbag shock absorbers are widely used in various vehicle models. In luxury cars and high - performance sports cars, active airbag shock absorption systems are mostly adopted. These systems can sense real - time changes in the vehicle body through sensors, precisely adjust the airbag pressure and air volume, providing ultimate driving comfort and handling stability. In ordinary passenger cars and commercial vehicles, passive airbag shock absorbers are more common. They have fixed gas inside and can automatically adjust the hardness of the airbag according to the degree of vehicle body vibration, effectively coping with various road conditions during daily driving. Many vehicle models, from heavy - duty trucks such as Auman and HOWO to high - end cars such as BMW and Land Rover, benefit from airbag shock absorption technology.
Rail Transit
Rail transit tools such as trains and subways are gradually introducing airbag shock absorption technology. During the operation of the train, airbag shock absorbers can be installed between the wheels and the vehicle body, effectively absorbing the vibrations caused by uneven tracks, reducing the bumpiness in the carriage, improving the comfort of passengers. At the same time, it also helps to reduce the wear of vehicle components caused by vibration and extend the service life of the vehicle.
Industrial Equipment
In the industrial field, airbag shock absorbers also play an important role. Washing equipment and laundry dehydrators generate strong vibrations during operation. Airbag shock absorbers can stabilize the equipment and reduce the impact of vibrations on the surrounding environment. Amusement equipment such as carousels can operate more smoothly with the use of airbag shock absorption, ensuring the safety of tourists and their playing experience. Papermaking machinery, leather shaking machinery, vibrating screens, mining equipment, as well as pipeline equipment, ship equipment, precision equipment, etc., also rely on airbag shock absorption technology to improve the stability and reliability of equipment operation, ensure product quality, and reduce equipment failure rates.
