This BPW development means there are no restric-

Air bag cover modal transport.
The functional principle is simple. The trailing arms
and the air suspension airbags are in two parts: The
Bump stops
trailing arms have a conical adapter, and the air
Air bag
bags have a special piston.
If the vehicle is raised after the air is exhausted
Rolling piston
(fibre-reinforced plastic) from the suspension, the axles move downwards.
(Air bag piston) The air bags remain in the rest position, the trailing
arms with the adapter move downwards.
Piston
When the vehicle is lowered to the ground, the air
suspension unit recombines with absolute safety.
Bottom bag attachment
The air bags can neither fold nor crease. This
means a long service life is guaranteed.
When driving on road, there is no difference be-
tween the combination air bag and a conventional
BPW air suspension.
R Reemmaarrkkss::
The shock absorber acts as an end stop in this
configuration, therefore it is necessary to ensure
that shock absorbers with a corresponding length
and loading capacity are installed.
Split air bags are available as BPW 30 K or BPW
30.
