Abstract
The dual mass flywheel reduces torsional vibrations by being mounted between the engine and the transmission, The dual mass flywheel includes a primary mass configured to couple to a crankshaft, and a first drive plate coupled to said primary mass by disposing a main elastic member therebetween. A pair of second drive plates are coupled to said first drive plate by disposing an idle elastic member therebetween. A secondary mass is fixedly coupled to said pair of second drive plates.
