Common Faults and Cause Analysis of Rubber Air Springs
| Fault phenomenon | Cause Analysis |
| Air spring collapsed | The air pressure in the air tank is too low to open the pressure protection valve
Air control line manifold leaking or clogged
Failed height control valve or loose flexible link |
| Air spring surface is worn or worn through | Insufficient clearance around the air spring and friction with other parts
The loose shock absorber, loose pipeline, etc. cause interference and friction with the airbag
There is sand, glass slag, etc. on the outside of the piston of the air spring base |
| Air spring upper seat plate depression | The suspension height is too low, and the air spring works under low air pressure for a long time.
Failed height control valve or loose flexible link
wrong air spring
The air supply pressure is low and the vehicle is seriously overloaded |
| Air spring upper base plate bulge | Shock absorber failed, damaged or wrong type
Altitude control valve not working
The suspension height is too high, and the air spring works under supernormal air pressure for a long time
wrong air spring |
| Cracks or air leakage at the junction of the air spring and the upper seat plate or lower seat plate, or air leakage at the root of screws and bolts | The air supply pressure is too high and the overload is serious
Shock absorber failed, damaged or wrong type, air bag stretched too long
Eccentric contact of the cushion, resulting in partial damage at the junction of the airbag and the upper edge plate or the piston |
| Air spring skew, eccentric contact of cushion | The air spring is not installed correctly, the air spring is skewed longitudinally
Incorrect suspension installation, air springs are skewed laterally
The positioning adjustment block on the frame bracket is welded or the rubber bushing in the pin ear is damaged, causing the suspension to drift |
| Air sac | Premature aging caused by grease, etc. on the airbag
normal aging |
| Less elastic, more rigid | The water vapor in the air tank is not released in time, and more and more water accumulates in the air spring |
