Claim:
An air-suspension system for a vehicle, comprising: at least one front axle air-bellows valve assigned to at least one air-spring bellows of a front axle for individually aerating and venting the at least one air-spring bellows of the front axle; at least one rear axle air-bellows valve assigned to at least one air-spring bellows of a rear axle for individually aerating and venting the at least one air-spring bellows of the rear axle; at least one central aeration valve for supplying the at least one air-bellows valves assigned to the at least one 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 at least one air-bellows valves assigned to the at least one air-spring bellows of the front axle and the rear axle, to a compressed-air supply; wherein one of the following is satisfied: 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, an air vent, the central venting valve, and the at least one air-bellows valve assigned to the rear axle occurs via at least one throttle; or 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 rear axle and, on the other side, the air vent, the central venting valve, and the at least one air-bellows valve assigned to the front axle, occurs via the at least one throttle.
