Purpose, Function
• In addition to its primary function as a flywheel, it reduces vibration and noise related to the drive system by reducing fluctuations in engine speed and stabilizing the rotation of the transmission.
Construction, Operation
Basic Operation of dual-mass flywheel
• The construction consists of arc springs positioned between the two flywheels. Depending on the driving conditions, the springs compress and release repeatedly in accordance with the acceleration torque from the primary flywheel side and the deceleration torque from the secondary flywheel side to reduce engine speed fluctuations.
