STRUCTURE OF DUAL MASS FLYWHEEL TO PREVENT LEAKING OIL

摘要

A structure of a dual mass flywheel for preventing oil leakage is provided to install a diaphragm between one end of a cover and a drive plate for preventing the lubricant filled in a chamber from leaking through a gap between the cover and the drive plate. In a structure for a dual mass flywheel, a primary mass and a secondary mass combined to an engine crankshaft and to a transmission input shaft respectively are installed to be rotated relative to each other, a chamber(10) enclosed in a cover(9) and filled with lubricant is installed at an end of the primary mass, and a drive plate is installed in the secondary mass. A diaphragm(20) is installed between an end of the cover and the drive plate to prevent the lubricant from leaking through the gap between the cover and the drive plate. A mounting protrusion(9a) is disposed at one end of the cover to be tightly adhered with one end of the diaphragm.
