Double-counterpoised flywheel for an internal combustion engine

摘要

A double-counterpoised flywheel for an internal combustion engine. A counterweight is disposed on the engine side and another counterweight is disposed on the transmission side, both counterweights allowing limited mutual rotation through the intermediary of elastic members. A damping system is arranged between the two counterweights and parallel to the elastic members. The two counterweights bear on each other radially and axially through an antifriction bearing. The inner race of the antifriction bearing is mounted between a stop face of the primary mass and a holder disk that is secured to the end face of the primary mass on the power take-off side. The holder disk is provided with at least two pins which are created by driving them out of the material of the holder disk ("part-shearing") toward one and the same side of the holder disk. The end face of the hub of the primary mass is provided with holes for receiving the pins, which pins are pinch-fitted into the holes.
