Abstract:
A suspension system includes spring bellows that are associated with pneumatic springs of vehicle axles, are connectable by lines having level control valves to a main pressure line, and can be shut off with respect thereto. The main line is connectable by valves alternately to a compressed air source and a sink, and can be shut of with respect thereto. To set different air mass flow rates when air is supplied to/removed from the bellows, the bellows of the springs at least on a vehicle axle or side can be connected to the main line in parallel with the connecting lines, at least by further connecting lines having further level control valves, and can be shut off with respect thereto. The further valves have nozzle cross-sectional surfaces the same size as the other level control valves. Chokes are downstream of the further valves in the ventilation direction, the cross-sectional surfaces thereof being smaller than the nozzle cross-sectional surfaces of the further valves.
