About Suspension Air Springs
- Adjustability: By filling or releasing air, the spring's stiffness and height can be easily adjusted. This allows the vehicle to:
- Leveling: Maintaining the same height regardless of load (empty or fully loaded) ensures headlight coverage and driving stability.
- Adjusting Height: Certain applications (such as off-road vehicles and specialized trucks) require the chassis to be raised or lowered.
- Adjusting Comfort: Adjusting the suspension's firmness or firmness based on road conditions or personal preference.
- Lightweighting: Compared to metal springs, air springs are lighter, helping improve fuel economy.
- Smooth and Quiet: Providing a smoother, quieter ride while effectively filtering out road vibrations.
Main Applications
- Commercial Vehicles: Trucks, buses, and trailers (the most traditional application, used to ensure vehicle balance after loading).
- Passenger Vehicles: Suspension systems (such as air suspension) in high-end sedans and SUVs provide comfort and driving stability.
- Industrial Equipment: Used as shock absorbers in precision instruments, machinery, and other equipment.
