What is Active Air Suspension?
3 Answers
In the process of driving, the chassis suspension system actively adjusts the stiffness and height of the shock absorbers according to road conditions. Currently, there are two representative types: electromagnetic suspension systems and air suspension systems. These are relatively high-end comfort configurations, mostly found in luxury vehicles. Additional information: The working principle of air suspension involves using an air compressor to form compressed air, which is then delivered to the air chambers of the springs and shock absorbers to alter the vehicle's height. Height sensors are installed near the front and rear wheels. Based on the output signals from these sensors, the computer determines changes in the vehicle's height and controls the compressor and exhaust valve to compress or extend the springs, thereby achieving a damping effect.
The active air suspension is an intelligent automotive system that replaces traditional steel springs with air springs, working in conjunction with sensors and control modules to adjust suspension height and stiffness in real time. Sensors monitor wheel movement and road condition changes, while the computer calculates the optimal settings within milliseconds. An air pump inflates or deflates the airbags to adjust pressure, allowing the suspension to switch between soft and firm modes—lowering the vehicle at high speeds to reduce drag and enhance stability, or raising it on rough roads to absorb shocks. This system is commonly found in luxury cars and SUVs, requiring regular checks for airtightness and leak-proof components. Although maintenance costs are slightly higher, it significantly improves driving comfort.
I've driven a car with active air suspension for several years, and what impressed me most is its automatic balance between comfort and handling – it glides softly over potholes without jolting (no more crying kids), while stiffening on high-speed curves to reduce body roll with magical stability. The system adjusts with one click based on speed or driving modes – raising the chassis for off-road protection or lowering it for fuel efficiency and quietness during daily commutes. Maintenance like checking airbag condition is crucial, as repairs for leaks can be costly. But for long family trips, the rock-steady ride is absolutely worth it.
