1 Trailing arms

General

BPW Trailing arms
The trailing arm connects the axle to the vehicle frame via
O the air suspension hanger brackets and the air bag. BPW
trailing arms (single or twin leaf) are highly fl exible spring
steel elements. They are hot-rolled from one piece, after
which they are shot-peened, cataphoretic dip-coated and
SL
zinc-phosphated.
Trailing arms absorb much of the lateral forces and reduce
the torsional forces input into the axle beam. Various
AL trailing arm versions permit optimisation of axle load,
track, spring centre, centre of gravity height and driving
comfort. In every situation, their stiff ness and fl exibility
are exactly matched to the vehicle and its application.
This reduces the stress on the body and ensures that the
vehicle achieves a long service life.

If single leaf trailing arms are mounted, the catch strap

offers the necessary safety reserves if the worst should
come to the worst.

Long-life steel-rubber-steel bushes (up to 4 times the
service life of rubber-steel bushes) off er maintenance-free
mounting of the trailing arm.
The axle is precisely located, and tyre wear and operating
costs are both reduced.
