VEHICLE LOW-NOISE POWER UNIT Russian patent published in 2003 - IPC

Abstract RU 2219399 C2

FIELD: mechanical engineering; internal combustion engines. SUBSTANCE: proposed device contains internal combustion engine with flywheel fitted on engine crankshaft. Flywheel is mechanically coupled with clutch driven disk. Through holes are made in disks part of flywheel arranged between outer surfaces of clutch disk and flywheel proper at equal distances from said surfaces. Axes of holes are located at equal distance from each other. EFFECT: improved acoustic characteristics of power unit owing to decrease of noise produced by vibrating structure of flywheel. 5 dwg
