Dual Mass Flywheel

The Dual Mass Flywheel (DMF) is primarily used for damping of oscillations in automotive power trains and to prevent gearbox rattling. The dual mass flywheel (DMF) can create an improved driving experience for manual shift vehicles. Vibrations and noises that occur during vehicle operation are absorbed. Fuel consumption is reduced. This results in economical driving comfort. Dual mass flywheel is a multi-clutch device which is used to dampen vibration that occurs due to the slight twist in the crankshaft during the power stroke .When the power stroke subsides, the crankshaft untwists. One would not think a crankshaft would twist to any significance, but any piece of metal always deflects a little when a force is applied to it. The rate that these vibrations occur is referred to as the torsional frequency. Transaxles experience torsional vibrations also. When torsional frequencies of the crankshaft match those of the transaxle an effect known as torsional resonance occurs, which may cause excessive wear on the drivetrain components.
