3 DMF components

. Secondary mass

The engine torque is transferred from the primary

mass to the secondary mass via the arc springs and

the flange. Thanks to the bearing between the primary

and secondary mass, independent radial movement of

the masses is possible. As with a rigid (single-mass)

flywheel, the power output is through the clutch, which

is bolted to the secondary mass. The crucial difference,

however, is that the engine torque is now largely free of

rotational vibration, i.e. it is modulated. Because of this,

a clutch disc with torsion damping can be dispensed

with in most cases if a DMF is used.
