Common Causes and Trouble Shooting Methods of Trailer Air Suspension
1.Insufficient Air Spring Pressure
| Reasons | Insufficient air supply pressure |
| Abnormal pressure protection valve |
| Height valve not working |
| Air leakage or pipeline damage |
| Air spring puncture or leakage |
| Trouble Shooting Method | Make the vehicle pressure reach 0.6MPa |
| Check the pressure protection valve |
| Replace if necessary |
| Check the height control valve |
| Find the air leakage and repair it |
| Replace the air spring with a new one and check whether the surrounding clearance meets the requirements |
| Check the shock absorber at the same time |
2.Broken Air Spring
| Reasons | Tires or brake parts rubbing against air springs |
| Brake chamber and air spring friction |
| Suspension height is too high |
| Wrong shock absorber model |
| Trouble Shooting Method | Check the gap around the air spring, if it is too small it must be reinstalled |
| Change brake chamber position or turn clamp to increase clearance |
| Adjust the height valve to the correct height |
| Replace shock absorber |
