BALANCING OF VEHICLE COMBINATIONS
1-1
1. GENERAL
1.1 INTRODUCTION
G
=
weight
m
=
earth
a
=
deceleration (m x a is the force
changing the axle load)
Dynamic axle load: When the brakes are
applied, the load on the axle increases.
F
=
braking force (Fmax = Gd x
µ)
Gd
=
dynamic axle load
m
=
the friction coefficient between
tyre and road
Fn
=
braking force of the wheel
brake.
How is a good braking performance of a vehicle
combination (truck/trailer, tractor/semi-trailer)
achieved, both for new vehicle combinations
and reconditioning of the brakes, while still
guaranteeing interchangeability?
The vehicles should meet the legal requirements
and all settings should be in accordance with the
directives. However, adhering to the directives
does not necessarily mean that there will be no
brake problems.
