LuK explains how aircraft technology has been used to improve the dampening
properties of Dual Mass Flywheels.
The Dual Mass Flywheel (DMFs set a new standard for drivetrain noise insulation and
vibration damping when launched by LuK in 1985. A total of 63 million DMFs have
since been manufactured and one in three cars on European roads currently use DMF
technology to aid comfort and reduce fuel consumption and CO2 emissions.
LuK have now taken this technology a step further by incorporating centrifugal
pendulum-type absorbers into the DMF. Centrifugal pendulum absorbers have been in
existence for decades and are primarily used in aircraft engines. By integrating the
number of small centrifugal pendulum absorbers, into the DMF, LuK have been able to
significantly increase the damping characteristics of the DMF.
The centrifugal pendulum absorbers are mounted into the drive flange of the DMF which is
subsequently attached to the secondary mass. This gives the flywheel extra inertia which
is variable with engine speed, so low down the rev range where we see the most vibration,
this extra inertia can adjust the amount of absorption, thus reducing the amount of
vibration. A pendulum mass of just one kilogram is all it takes to reduce the vibration
transmitted to the transmission by up to 60%.
