1 Leaf springs

1.1 General

BPW VB suspension units are equipped with parabolic
or multi-leaf springs.
Depending on the version, parabolic springs have two OD\HU OHDI VSULQJ
or three parabolic rolled spring layers. The effi cient use
of material enables them to combine low weight with a
low height.
Multi-leaf springs (trapezoidal springs) contain a stack of
OD\HU OHDI VSULQJ
spring layers with a constant cross-section and graded
lengths to give a trapezoidal shape.
They are characterised by their robustness and good
default driving properties as well as the ease of replacing
individual spring layers. 0XOWL OHDI OHDI VSULQJ
The ends of the leaf springs are mounted on sliding
bearings using spring slides both in the connecting
pieces and in the equalising beams.
This allows the spring pack to increase in length without
obstruction when the suspension defl ects.

As a load-bearing component of the suspension unit, the
leaf spring requires particular attention.
The following instructions should be carefully adhered to
during repair and maintenance work:

Do not work on leaf springs with a hammer or any
sharp objects.
Do not work on leaf springs with cutters
or grinders.
In the event that replacement springs or leaves
do not fi t exactly into the seat of the spring pads,
the mounting seat must always be widened.
Double or triple parabolic springs can only be
completely replaced.
Individual leaves can be replaced in multi-leaf
springs.

 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.
