Dual-mass flywheel concept for internal combustion engines, where the secondary flywheel (3) can be disconnected and reconnected as required, by means of a clutch (6). The concept is characterized in that it comprises a primary flywheel (2) fixedly mounted on the engine (1) crankshaft, a secondary flywheel (3) which is 5 stored so that it can rotate freely, a clutch (6) connecting the secondary flywheel to the drive shaft (5) (input shaft on the gearbox (9)), an elastic element (4) (springs) which connects the primary flywheel to the drive shaft.
