Problems solved by technology

[0005] Therefore, only in terms of rotational vibration and NVH of the vehicle drive system, it is advantageous that the inertial force of the flywheel is large and tends to increase with the weight and volume of the flywheel, and as a result, the size of the weight of the flywheel needs to be as large as possible. possible increase, but there is a limit to increasing inertia by increasing flywheel weight and volume given the relationship between vehicle weight and fuel efficiency and mountability

Abstract

An inertia incremental apparatus for a flywheel of an engine is provided to improve NVH performance of a vehicle driving system as well as rotary vibration generated from a crankshaft of the engine by remarkably increasing inertial force of the flywheel of the engine while occupying a relatively small volume and a relatively small weight to assure quiet and safe operability and ride comfort of a vehicle.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2011-0117521 filed on Nov. 11, 2011, the entire contents of which are hereby incorporated by reference for all purposes. technical field [0003] The present invention relates to a technology that can increase the inertia of an engine flywheel, and more particularly, relates to a technology that can effectively increase the inertia of a flywheel without increasing the occupied volume. Background technique [0004] The engine rotates the crankshaft by means of the power generated in the explosive stroke, since the explosive stroke is not continuous, torsional vibrations are generated in the crankshaft due to discontinuous power strokes, and since rotational vibration is not preferred in continuous drive of the vehicle, it will provide relative A flywheel of greater rotational inertia is mounted on the crankshaft, thereby dampening or reducing rotatio...
