Apparatus for damping flywheel

摘要

An apparatus for damping a flywheel includes a drive plate integrally connected to a crankshaft. A flywheel is connected to receive a rotating force from the drive plate through planetary gearing, and is mounted to rotate relative to the crankshaft. A rigidity imparting means is disposed on a path along which a rotating force is transferred between the drive plate and the flywheel. A mass body is provided on the flywheel, and is configured to perform relative rotation in a direction that offsets a torsional vibration of an engine transmitted to the flywheel.

1. An apparatus for damping a flywheel, comprising:
a drive plate integrally connected to a crankshaft; a flywheel configured to receive a rotating force from the drive plate through planetary gearing, the flywheel mounted to rotate relative to the crankshaft; rigidity imparting means disposed on a path along which a rotating force is transferred between the drive plate and the flywheel; and a mass body provided on the flywheel, the mass body configured to perform relative rotation in a direction that offsets a torsional vibration of an engine transmitted to the flywheel, wherein the planetary gearing comprises three rotary elements including a first rotary element connected to the drive plate, a second rotary element connected to the flywheel, and a rotary element adapted to constrain rotation, so that the second rotary element connected to the flywheel is connected to increase a speed relative to the first rotary element connected to the drive plate, and wherein the planetary gearing is provided with a carrier connected to the drive plate, a ring gear connected to the flywheel, wherein rotation of a sun gear is constrained, and wherein the rigidity imparting means is provided between the ring gear and the flywheel.
