Air-leveling system for a vehicle

摘要

An air leveling system for a vehicle wherein a check valve is connected between independent front and rear air lines for respectively feeding pneumatic pressure to front and rear shock absorbers. At least when the pneumatic pressure of the rear side shock absorbers is excessively higher than that of the front side shock absorbers, the pneumatic pressure at the rear side is discharged by the check valve to balance the pneumatic pressures at the front and rear sides to thereby hold the vehicle height at a predetermined level. The system provides for automatic correction of imbalance between the vehicle heights at the front and rear sides, particularly when the rear vehicle height is higher.
