An air spring system for a two axle motor vehicle has a compressed air source and control valves. The control valves are assigned to the individual motor vehicle wheels and by means of which the respective vehicle wheel air springs can be connected by choice to a compressed air supply line which is connected to the compressed air source. The air springs of the vehicle front axle and the air springs of the vehicle rear axle have their own compressed air line branches, whose cross sections differ at least by segments; and the line branch of one of the two axles is designed in such a manner that its flow cross section during compressed air infeed into the assigned air springs differs at least by segments from the flow cross section during compressed air bleeding from the assigned air springs. Preferably that line branch, whose flow cross section during compressed air infeed differs from that during compressed air bleeding, comprises parallel connected subbranches with flow cross sections that differ at least by segments; and at least one of the subbranches exhibits a suitably arranged non-return valve, which releases this subbranch only in one direction of flow.
