The invention is a control system for raising and lowering, as desired, the body (17) of vehicles with pneumatic suspension, with level control, with a compressed air source (21), at least one level control valve (15), pneumatic suspension bellows (24) assigned to at least one axle of the vehicle and a switching valve (1) with the positions raising, lowering, travel and stop, the level control valve (15) being connected into the line (3, 11, 23) which leads from the switching valve (1) to the pneumatic suspension bellows (24), an actuating device (5) for changing, as desired, the basic position of the level control valve (15) for the fixed normal level of the body (17) of the vehicle and thus for raising and lowering as desired by means of the level control valve (15) being provided between switching valve (1) and level control valve (15), the switching valve (1) having an automatic return device for returning from the raising or lowering position to the "stop" position, and a pressure limiting valve (28) being provided between the compressed air source (21) and the switching valve (1) for setting this normal level of the body (17) of the vehicle. <IMAGE> |
