The Difference Between Air Suspension And Pneumatic Shock

2022-02-24

The air suspension system is based on the different road conditions and the signal of the distance sensor, the trip computer will judge the change of the body height, and then control the air compressor and the exhaust valve to automatically compress or extend the spring, thereby reducing or increasing the ground clearance of the chassis. , in order to increase the stability of the high-speed vehicle body or the passability of complex road conditions.

The working principle of the pneumatic shock absorber is to change the height of the body by controlling the air pressure, which includes elastic rubber airbag shock absorbers, air pressure control system, trunk air storage tank and electronic control system.
Air Suspension Creates Background
 
Since its birth in the mid-19th century, the air suspension has undergone a century of development, and has experienced "pneumatic spring-airbag composite suspension → semi-active air suspension → central air-filled suspension (ie ECAS electronically controlled air suspension). system)” and other variations. It was not used in trucks, coaches, cars and railway cars until the 1950s.

At present, some sedans are also gradually installing and using air suspension, such as Lincoln in the United States, Benz300SE and Benz600 in Germany, etc. In some special vehicles (such as instrument vehicles, ambulances, special military vehicles and required container transport vehicles that require high shock resistance), the use of air suspension is almost the only choice.
