2 Axle clampings

2.1 General

BPW Axle clampings

The axle is connected to the leaf spring using the axle
connection comprising: spring plates, spring pads,
segments and U-bolts.

In contrast to BPW air suspension systems (clamped),
only welded axle assembly mountings are used with VB
suspension units.
This means that the spring pads are welded to the axle
beam.

Axle alignment

After repairs have been carried out on the axle beam,
connecting piece, connecting rods etc., the axle
alignment must be checked and if necessary corrected.

Determine the diagonal dimensions A - B and A - C for
the centre axle (reference axle) by means of comparative
measurements (± 2 mm tolerance).

Check and if necessary correct the wheelbase
dimensions B - D and C - E for the front axle, and B - F
and C - G for the rear axle (max. tolerance 1 mm).

Measurement is generally carried out by means of the
hub cap centre point (see illustration).
It can also be carried out using screwed-in graduated
tubes.
Correct any discrepancies by means of the adjustable
connecting rods or the adjustable hanger brackets
(VB ECO Cargo).

Hub cap centre point in the BPW logo

The triangle ( ) in the BPW logo is positioned centrally
if there is an ® or ECO stamped below the BPW logo
(since 1989/1994).

 Important for all welding work !
The leaf springs, plastic pipings and other
sensitive parts should be protected against
sparks and weld splashes during all welding
work.

The earth terminal must under no
circumstances be attached to the
leaf spring or hub.
