An air-suspension device for vehicles, e.g., commercial vehicles, includes a valve block that is assigned to a rear axle and contains a central valve for aerating and venting air-spring bellows of the rear axle, and a valve block assigned to a front axle for aerating and venting air-spring bellows of the front axle. The central valve of the valve block assigned to the rear axle selectively connects: a) a compressed-air supply to the air-spring bellows of the rear axle and to a supply-pressure connection of the valve block assigned to the front axle; or b) the supply-pressure connection of the valve block assigned to the front axle and the air-spring bellows of the rear axle to an air vent. The valve block assigned to the front axle has a pneumatic pilot-operation connection for pneumatic-electric pilot operation. The pneumatic pilot-operation connection of the valve block assigned to the front axle is connected to a pressure outlet of a selector-valve device, of which one pressure inlet is connectable, via the central valve of the valve block assigned to the rear axle, either to the compressed-air supply or to the air vent, and the other pressure inlet is connectable to at least one of the air-spring bellows of the front axle. The selector-valve device switches through, in each instance, the higher of the pressures applied to its pressure inlets to the pressure outlet. By this arrangement, the need for pneumatic lines is eliminated.
