Abstract
A friction damping device (,) capable of generating friction torque for controlling the relative rotation of a first and a second flywheel mass of the twin mass flywheel (,), the friction damping device comprising a first (,) and a second (,) friction member operatively connected with one flywheel mass (,) via a common drive formation (cdf) which forms part of the second friction member. A third friction member (,) is sandwiched between the first and second friction members and is operatively connected with the other flywheel mass (,), and actuating means (,) is operative to axially displace the first and second friction members relative to each other to modify the friction generated by the device upon rotation of the third friction member relative to the first or second friction members resulting from relative rotation of the flywheel masses.
