Two part flywheel for a motor vehicle, the two part flywheel having a torsional vibration damper

摘要

A two part flywheel having a torsional vibration damper with a plurality of inertial masses, for installation in the drive train of a motor vehicle. The two part flywheel comprises a first inertial mass system and a second inertial mass system. The first inertial mass system comprises a plurality of planet gears. The second inertial mass system comprises a sun gear. The planet gears solely engage with the sun gear. The first inertial mass system also comprises a first planar annular wall disposed substantially perpendicular to the common axis of rotation. The second inertial mass system also comprises a second planar annular wall disposed substantially perpendicular to the common axis of rotation. At least a portion of each planet gear of said plurality of planet gears is disposed between said first annular wall and said second annular wall.
