  • Air suspension system of a vehicle
    Patent number: 6824146
    Abstract: An air suspension system for a vehicle wherein a valve means for varying the resilience of an air spring in response to changes of vehicle height is integrally formed with an air spring to be mounted on the vehicle frame such that the installation space of the air suspension system can be minimized. As a result, cumbersome processes involved with the manufacture of the vehicle can be eliminated to provide an improved convenience for workers. A conventional lever used for connecting a leveling valve and an air spring is dispensed with to reduce the number of parts constituting the air suspension system and lower the manufacturing cost.
