A dual-mass flywheel (DMF) is different than a traditional flywheel as it’s made with two metal plate designed to rotate against each other.
A dampening system in the form of arc springs is integrated into the DMF and helps to absorb the noise and vibration. In drivetrains with a single-plate flywheel, vibration and noise have nowhere to go except directly into the powertrain system.
The DMF system can reduce noise, increase driver comfort and extend the life of the transmission.
Today, a DMF is installed in half of all cars produced globally – Joe Keene explains service and repair requirements with any dual-mass flywheel.
