AIRSUSTECH Complete Air Spring Core Functions and Values
1. Dynamic load adaptation
|
Principle: Change the spring stiffness in real time through air pressure adjustment, automatically adapting to different loads (no load → full load). |
| Effect: Reduce air pressure when unloaded → suspension becomes softer, improving driving comfort Increase air pressure when fully loaded → suspension becomes harder, preventing chassis from bottoming out and protecting cargo |
2. Vehicle height control
With height control valve (such as Wabco or Knorr-Bremse system):
| Keep the cargo box/carriage at a constant height from the ground (±5mm error) |
| Achieve side kneeling function (bus platform tilted to facilitate passengers to get on and off) |
|
Automatically level the saddle when trailer is connected |
3. Active shock absorption and stability improvement
Compared with leaf spring advantages:
| Scenarios | Complete Air Spring | Leaf Air Spring |
| Bumpy road | Absorb more than 80% of impact | Vibration is directly transmitted to the frame |
| Tilting in curves | Suppressing the roll angle>40% | Relying on stabilizer bar, limited effect |
| Emergency braking nod | Reduce 50% of the front pressure | Obvious dive phenomenon |
