Airlight Direct 6.6

G Geenneerraall
The Airlight Direct unit is particularly well suited to
intermodal transport because it is equipped with an
integrated split air bag as standard. In addition, it
is characterised by a high level of comfort and low
weight.
With ccoonnvveennttiioonnaall aaiirr ssuussppeennssiioonnss the axle load is
distributed partly through the air bag and partly
Combination air bag joined through the hanger bracket. The proportion through
each is determined by the ratio of the trailing arm.

In the nneeww AAiirrlliigghhtt D Diirreecctt a aiirr ssuussppeennssiioonn system from
BPW, the air bag is located directly above the axle,
so that the air bag absorbs 100 % of the axle load.
This adds up to a comfortable suspension, com-
bined with low superstructure acceleration values.

A Aiirrlliigghhtt D Diirreecctt is fitted with air bags that have a split
piston as standard. Automatic separation and
joining of the axle and air bag means there is no
risk of the bags creasing and therefore becoming
damaged in the course of railway or ferry trans-
Combination air bag separated
shipment.

When installing the air bag (V = 30), drill through
the bottom flange of the vehicle frame in order to
5 22 accommodate the M 12 fixing bolt (Detail X).

In order to support the airbag, the bottom flange
width should be at least 200 mm. If it is less, a
Ø 13 plate must be installed between the frame and the
top plate of the bag.
