DUAL MASS FLYWHEEL

摘要

The present invention relates to a dual mass flywheel which minimizes frictional resistance, stable workability, and absorbs the noise and vibration generated by various characteristics, and the dual mass flywheel includes: a primary flywheel having a ring gear and connected to an output shaft of an engine; a secondary flywheel connected to an input shaft of a transmission; a coupling element for coupling the primary flywheel and the secondary flywheel to each other; and a plurality of drive units coupled to the primary flywheel and the secondary flywheel to transmit the torque of the primary flywheel to the secondary flywheel and having spring guides coupled to torsion springs so as to reduce the noise and vibration generated during the torque transmission process, wherein the primary flywheel includes a unit groove formed to accommodate the drive units thereinto and deviation prevention protrusions having operating slots formed on the top and underside of the center line of the unit groove to prevent the deviation of the driver units therefrom; the secondary flywheel includes driving pins protruding from the underside thereof to compress and damp the drive units; and the torsion spring of each drive unit has a linear spring and a curve spring interposed between the end guide and the middle guide or between the middle guide and the middle guide.
