  • Air-suspension device for vehicles, in particular for commercial vehicles
    Patent number: 7396029
    Abstract: 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.
