Advantages of Air Suspension Shock Absorber
1. Ideal axle height
The car can be kept on its ideal axle height independent of its variable load. Driving safety is improved due to better road handling, for example, at night keeping the same headlight position.
2. Improve driving dynamics, road handling and comfort
Driving dynamics, road handling and comfort are improved. The suspension is soft and comfortable during slow driving and becomes noticeably stiffer during faster driving. The suspension responds to dynamic load as it reacts to live load.
3. Better sound isolation and lower resonance frequency
Better sound isolation of airbag and lower resonance frequency, which leads to a smoother and more comfortable ride.
4. Absorber energy
Higher ability to absorb energy which means better and safer handling in extreme driving conditions.
