Abstract
A vehicle air suspension system includes at least two spring bellows assigned to pneumatic springs on opposite vehicle sides of a vehicle axle. The springs can be connected via connection lines, each of which is provided with a level-regulating valve, to a main pressure line and can be shut off with respect thereto. The main pressure line can be connected via a main pressure valve alternately to a compressed air source and to a compressed air sink. The connection lines of the spring bellows are connected to each other via a connection line provided with a throttle and can be shut off by a shut-off valve. A mechanically activatable shut-off valve is coupled to one of the level-regulating valves arranged on the offside of the vehicle such that the shut-off valve is open when the level-regulating valve is closed and is closed when the level-regulating valve is open.
