Principles of air suspension
Self-levelling air
suspension
Air suspension is a controllable form of
vehicle suspension.
With air suspension, it is simple to achieve
self-levelling and it is therefore generally
integrated into the system.
The basic advantages of self-levelling are:
• Static compression remains the same,
irrespective of vehicle loads (see overleaf).
The space requirement in the wheel
arches for free wheel movement kept to a
minimum, which has benefits for the
overall use of available space.
• The vehicle body can be suspended more
softly, which improves driving comfort.
• Full compression and rebound travel is
maintained, whatever the load.

• Ground clearance is maintained, whatever
the load.
• There are no track or camber changes
when vehicle is laden.
• The c
w
value is maintained, as is the visual
appearance.
• Less wear to ball joints due to reduced
working angle.
• Greater loads are possible if required.
