The unsprung masses
The aim in principle is to minimise the volume
of unsprung masses and their influence on
the vibration characteristics (natural
frequency of the bodywork). Furthermore, a
low inertia of masses reduces the impact load
on the unsprung components and
significantly improves the response
characteristics of the suspension. These
effects result in a marked increase in driver
comfort.
Examples for the reduction of unsprung
masses:
• Aluminium hollow spoke wheel
• Running gear parts (swivel bearing, wheel
carrier, links etc.) made of aluminium
• Aluminium brake callipers
• Weight-optimised tyres
• Weight optimisation of running gear parts
(e.g. wheel hubs)
