Vehicle suspension 
When a vehicle travels over irregular road 
surfaces, impact forces are transmitted to the 
wheels. These forces pass to the bodywork 
via the suspension system and the wheel

During driving operation, the vehicle body is 
subject not only to the forces which cause the 
upward and downward motion of the vehicle, 
but also the movements and vibrations in the 
direction

Principles 
The suspension system 
As ÓsupportingÓ components of the 
suspension system, the suspension elements 
form the connection between the wheel 
suspension and the bodywork. This system

The unsprung masses 
The aim in principle is to minimise the volume 
of unsprung masses and their inßuence on 
the vibration characteristics (natural 
frequency of the bodywork). Furthermore, a

Principles 
The natural frequency of the bodywork  
The vibrations are deÞned by the degree of 
amplitude and its frequency. The natural 
frequency of the bodywork is particularly 
important dur

The natural frequency of the bodywork is 
essentially determined by the characteristics 
of the springs (spring rate) and by the sprung 
mass.
Greater mass or softer springs produce a 
lower natu

The degree of damping of the vibration 
damper has no signiÞcant inßuence on the 
value of the natural frequency of the 
bodywork. It inßuences only how quickly the 
vibrations cease (damping
