Abstract
The dual mass flywheel comprises a spring assembly (4; 104; 112; 128; 129), if necessary, with two stages of which one can include a spiral spring. Furthermore, the dual mass flywheel comprises a friction damping system (111) that applies torque independently of the rotational speed of the flywheel.
