 History
The rapid development of vehicle technology over the
last few decades has brought ever higher-performance
engines paralleled by an increased demand for driver
comfort. Weight-saving vehicle concepts and wind tunnel-
optimised bodies now allow other sources of noise to be
perceptible to the driver. In addition, lean concepts,
extremely low-speed engines and new generation gear-
boxes using light oils contribute to this.
From conventional torsion damping to
dual mass flywheel
Since the middle of the 1980s, this advancement has
pushed the classic torsion damper as an integral part
of the clutch driven plate to its limits. With the same or
even less installation space available, the classic torsion
damper has proved inadequate to outbalance constantly
increasing engine torques.
Extensive development by LuK resulted in a simple, but
very effective solution – the dual mass flywheel (DMF) –
a new torsion damper concept for the drive train.
