The Role of Convoluted Air Spring in Vehicle Suspension
1. Main Functions of Vehicle Suspension
Load Support: Air springs support the weight of the vehicle while maintaining ride height and dynamically adjust to changes in load (such as passengers or cargo).
Shock Absorption: They absorb road shock and vibrations, improving ride comfort by isolating the chassis from uneven roads.
Adjustable Stiffness: The spring stiffness can be changed by adjusting the air pressure to balance comfort and handling (softer springs for luxury models, stiffer springs for high-performance models).
2. Main Benefits
Adaptive Ride Height: Compressed air adjusts the height of the spring to keep the vehicle level under different loads (for trucks, buses and luxury cars).
Enhanced Comfort: Softer initial compression than metal springs, reducing the bumpy feeling on bumpy roads.
Durability: The elastic rubber structure is more resistant to wear and corrosion than steel springs.
Customizable Performance: Integration with electronic control systems (such as adaptive suspension systems) allows real-time adjustments.
3. Applications
Commercial Vehicles: Trucks and buses use corrugated air springs for load leveling and stability control.
Luxury: Brands like Mercedes-Benz and Audi use corrugated air springs for a smooth, adjustable ride.
Off-road/Heavy Duty: Enhanced articulation and load capacity in rough conditions.
4. How it works
Rubber bellows: The corrugated (folded) design expands/contracts with changes in air pressure.
Air supply: The onboard compressor inflates/deflates the spring via a valve, which is usually managed by a sensor and ECU.
Piston (optional): Some designs include a piston to control the progressive spring rate.
5. Comparison with other springs
| Features | Corrugated air spring | Coil spring | Leaf spring |
|--------------|-------------------------|-------------|-------------|
| Adjustability | High (pressure-based) | None | Limited |
| Comfort | Excellent (adjustable) | Good | Stiff/harsh |
| Load capacity | Dynamically expandable | Fixed | High but stiff |
| Complexity | Higher (needs air system) | Simple | Simple |
