1) Overview
Dual mass flywheel (DMF)
- Manual transaxle
Drive plate
- Automatic transaxle
Dual mass flywheel reduces the unbalanced
rotation of crankshaft in manual transaxle
equipped vehicle. The flywheel is installed on the
crankshaft and is engaged to the clutch disc to
transfer the driving torque from the engine to the
powertrain system. Additionally, DMF decreases
the rattling noise in transaxle and the vehicle
vibration by reducing the differences of torque and
rotational speed due to the combustion in engine.
The drive plate initially drives the powertrain
system by using the power from the start motor
when starting the engine. The drive plate is
installed on the crankshaft and is engaged to the
torque converter of automatic transaxle to transfer
the driving torque from the engine to the powertrain
system.
