A device for the air-assisted suspension of a vehicle with at least one power axle and one raisable lifting axle is proposed, by means of which the level of the vehicle body and the axle loading of the individual axles can be controlled. A valve arrangement (12) for the power axle and a valve arrangement (17) for the lifting axle function with different pressure circuits, independent of one another, so that a separate control of the air pressure in the air springs (1, 2) of the power axle and in the air springs (3, 4) of the lifting axle is possible. The air springs (1, 2) of the power axle can be controlled independently of one another, whilst the air springs (3, 4) of the lifting axle are connected to one another. The device functions with only six valves (21, 22, 23, 31, 32, 33) which can be actuated by signals of an electronic control unit (45). <IMAGE> |
