Air Suspension Level Control System
History
- General
The function of the level control system is to maintain the height
of the vehicle body as closely as possible at a prespecified level
under all load conditions.
Thanks to the extensively constant level, the geometric wheel
suspension data (e.g. wheel camber, toe-in) remain unaltered by
the load. The ride comfort is also not dependent on the load.
The headlight range remains extensively constant over the entire
load.
BMW previously supplied level control systems as both special
equipment and, in part, as standard equipment on the BMW 7
Series - E23/E32, 6 Series - E24 and 5 Series -
E12/E28.
Hydropneumatic suspension
Partially loaded hydropneumatic rear-axle suspension forms the
basis of these systems.
It is similar in its basic principle to pure air suspension. However
it operates with a volume of gas which is permanently contained
in the pressure accumulator (i.e. constant).
The gas used is nitrogen. The internal chamber of the pressure
accumulator is divided by a diaphragm into individual gas and
hydraulic fluid chambers.
