Apparatus for compensating for fluctuations of transmission of torque by an internal combustion engine

摘要

Apparatus for transmission of torque between the crankshaft of the internal combustion engine and the input shaft of the change-speed transmission in a motor vehicle has a flywheel composed of two coaxial sections which are rotatable within limits relative to each other against the opposition of an interposed damper. One of the sections is bolted to the crankshaft and the other section is mounted on two antifriction bearings which surround a tubular support of the transmission housing. A friction clutch is interposed between the second section of the flywheel and the input shaft of the transmission. The mounting of the second section on the housing of the transmission, instead of customary mounting of one section on the other section, prolongs the useful life of the apparatus because the bearings are subjected to less pronounced and more uniformly distributed wear and each of their parts can be fully lubricated in response to engagement of the clutch.
