Flywheel: Description and Operation

Flywheel

MINI COOPER S
On MINI COOPER S a dual mass flywheel is used to insulate the gearbox from torsional and transient vibrations produced by the engine or drive line. The flywheel consists of a primary and a secondary flywheel. The drive between the two is transferred by a torsional damper made up of four coil springs located in the inside diameter of the primary flywheel. Under high torque loading conditions the secondary flywheel can rotate in either direction up to 70 degrees in relation to the primary flywheel.
