Frequently Asked Questions

1. What is a cab air spring?

A cab air spring is an elastic element used in truck cab suspension systems. It uses compressed air to provide support, replacing traditional leaf or coil springs. It effectively reduces vibration, improves driving comfort, and protects the cab structure.

2. What are the core advantages of air springs?

Excellent shock absorption: Reduces the impact of road bumps on the cab, reducing driver fatigue.
Adjustable height: Adjusts the cab height using air pressure to adapt to different road conditions or load requirements.
Extended component life: Reduces vibration damage to the cab and chassis structure.
Lightweight: Lighter than traditional steel springs, helping to reduce fuel consumption.

3. What are the typical symptoms of air spring failure?

Cabin tilt or uneven height
Unusual jerky driving or reduced shock absorption
Airbag deflator (may be accompanied by a hissing sound)
Suspension system warning light illuminates

4. How can I tell if an air spring needs to be replaced?

Visually inspect the airbag for cracks, wear, or leaks.
The cab cannot remain level and continues to sink after adjusting the air pressure.
A decrease in the air pressure maintenance capacity was detected during the vehicle's annual inspection or maintenance.

5. What is the lifespan of an air spring?

It's generally 3-5 years or 200,000-300,000 kilometers. The actual lifespan depends on:

Road conditions (frequent driving on rough roads will shorten the lifespan)
Load conditions (overloading accelerates aging)
Environment (high temperatures and corrosive substances may damage the airbag material)

6. How should air springs be maintained?

Regular inspection: Visually inspect the airbag monthly for damage and leaks.
Clean the surface: Remove dirt, sand, and oil to prevent corrosion.
Avoid overloading: Strictly follow the vehicle's load limit.
Winter precautions: Use a low-temperature-resistant model in extremely cold regions to prevent the rubber from becoming brittle.

7. What adjustments are required after installation?

Inflate to the manufacturer's recommended pressure (refer to the vehicle manual).
Test the cab lift function for proper operation.
Perform a road test to check the shock absorption and any unusual noises.

8. What are the emergency procedures for an air spring leak?

If the leak is minor, temporarily inflate to a safe pressure and drive at a low speed to a repair station. If the leak is severe, the vehicle must be towed to avoid damage to other components.
