Abstract
An air-suspension system for vehicles, in particular for commercial vehicles, including at least one air-bellows valve assigned to an air-spring bellows or a group of air-spring bellows of the front axle for individually aerating and venting this air-spring bellows or this group of air-spring bellows; at least one air-bellows valve assigned to an air-spring bellows or a group of air-spring bellows of the rear axle for individually aerating and venting this air-spring bellows or this group of air-spring bellows; as well as at least one central aeration valve for supplying the air-bellows valves assigned to the air-spring bellows of the front axle and the rear axle with compressed air from a compressed-air supply; and at least one central venting valve for exhausting compressed air from the air-bellows valves assigned to the air-spring bellows of the front axle and the rear axle, to an air vent. The system provides that the compressed-air communication between, on one side, the compressed-air supply, the central aeration valve, and the at least one air-bellows valve assigned to the front axle and, on the other side, the air vent, the central venting valve, and the at least one air-bellows valve assigned to the rear axle take place via at least one throttle.
