It is impossible to imagine today's automotive world without the dual mass flywheel (DMF). As early as 1985, Schaeffler began production of the dual mass flywheel, starting a new era in drive train engineering. New solutions for reducing torsional vibrations and for vibration damping were required since the clutch plates with torsion dampers used until then could no longer fulfil the growing requirements. So far, the DMF has shown growing success, due not least to the trend towards increasingly high engine torques. Its ongoing development has remained hand in hand with the innovations that have characterised drive train engineering.
In addition to reducing torsional vibrations, the dual mass flywheel offers a further positive effect: it promotes travel in operating ranges that give favourable fuel consumption and thus makes an important contribution to reducing CO2 emissions.
While the DMF was originally developed for high performance engines, it has therefore also established itself as standard in the compact class. Leading vehicle manufacturers worldwide now rely on its effective vibration damping. In Europe, about one in three cars are now equipped with this convenient technology. Small commercial vehicles have also benefitted from the significant contribution made by the DMF towards the reduction now required in consumption and CO2 emissions and the increase in user-friendliness.
Schaeffler has made an important additional innovation with the integration of a centrifugal pendulum-type absorber, which has facilitated further significant improvements in comfort, consumption and emissions.
