Common faults of air springs
1. Air spring skew, eccentric contact of cushion
The air spring is not installed correctly, and the air spring is skewed longitudinally.
The suspension was installed incorrectly and the air springs were 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.
2. Air sac
Premature aging due to grease, etc. on the airbag.
normal aging
3. Decreased elasticity
The water vapor in the air storage tank was not released in time, and more and more water accumulated in the air spring.
