INERTIA INCREASE DEVICE OF AN ENGINE FLYWHEEL FOR IMPROVING THE NVH PROPERTIES OF A VEHICLE DRIVE SYSTEM BY CHANGING THE INERTIA AND RIGIDITY OF A FLYWHEEL

摘要

PURPOSE: An inertia increase device of an engine flywheel is provided to significantly increase the inertia of an engine flywheel with small volume and weight and to significantly improve the NVH performance of a vehicle drive system and rotational vibration from the crankshaft of an engine by adjusting rigidity between the crankshaft and the flywheel.;CONSTITUTION: An inertia increase device of an engine flywheel comprises a drive plate (3), a flywheel (5), and a rigidity providing unit (7). The drive plate is integrated with a crankshaft (1). The flywheel is connected to the drive plate to receive rotatory power from the drive plate through a planetary gear (PG). The flywheel relatively rotates about the crankshaft. The rigidity providing unit is arranged on the rotatory delivery path of the flywheel and the drive plate.;COPYRIGHT KIPO 2013
