Functions of Volvo Truck Suspension Airbags
| Shock Absorption and Comfort | Compressed air is used to cushion road vibrations, reducing driver fatigue and cargo damage. |
| Automatic Leveling | Automatically adjusts airbag pressure according to load weight to keep the vehicle body level. |
| Height Adjustment | The driver can adjust the chassis height through the control system to facilitate loading and unloading of cargo or adapt to different road conditions. |
| Protect the chassis | Reduce the impact of bumps on the frame and components, and extend service life |
Common Faults and Maintenance
Airbag leakage: caused by aging, cracks or poor sealing of rubber, which needs to be replaced in time.
Height valve failure: the vehicle body cannot remain level, and the valve needs to be cleaned or replaced.
Pipeline blockage/leakage: check the air pipe connection point and dryer.
Abnormal noise or tilt: it may be uneven airbag pressure or wear of mechanical parts.
Maintenance Suggestions
Regularly check whether the airbag surface is cracked or worn.
Keep the air dry (to prevent moisture from corroding the pipeline).
Replace aging parts according to the manual and avoid overloading.
