5.2 Air suspension
Application
The levelling valve is installed as a level control valve for load
depended control using the air bellows of vehicles with air
suspension. Depending on the version, additional functions,
such as 2. drive height, through a lap position control are
possible.
Principle of operation
Air spring valves are secured on the vehicle frame and are
connected to the axle with the round or fl at lever via leverage.
The pneumatic connections are made via a reserve connector
(1), two energy outfl ows (21 and 22), as well as via the vent (3).
When in the resting state, the valve is said to be in the so-called
fi nishing position, i.e. both infl ow and also outfl ow are closed.
