Air suspension system of a motor vehicle

摘要

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.

1. A vehicle air suspension system, comprising at least two spring bellows associated with air springs disposed on opposite vehicle sides of an axle of the vehicle, the at least two spring bellows being one of connected to and shut off from a main pressure line via connecting lines having level-regulating valves, the main pressure line being connectable via a main pressure valve alternately to a compressed air source and to a compressed air sink, the connecting lines being connected to one another via a further connecting line having a throttle; and a mechanically activatable shut-off valve coupled to one of the level-regulating valves of the spring bellows such that the mechanically activatable shut-off valve is open when the coupled one of the level-regulating valves is closed and is closed when the coupled one of the level-regulating valves is open.
