TORSIONAL DAMPER WITH INDEPENDENTLY ROTATING INERTIA MASSES AND CRANKSHAFT TO WHICH THE TORSIONAL DAMPER WITH INDEPENDENTLY ROTATING INERTIA MASSES IS APPLIED

摘要

A torsional damper with independently rotating inertia masses, wherein an inner inertia ring is located at an inner diameter portion of an outer inertia ring in an internal chamber defined by coupling of a case, so that the inner and outer inertia rings form a dual concentric circle, through which an axial hole is formed to a cover, the inner inertia ring is moved relative to rotation of the case, and then the outer inertia ring is moved relative thereto.
