Torsion vibration damper

Abstract

A torsion vibration damper comprises a first driving module and a second driven module that are mounted on bearings and are capable of rotational movement relative to each other, wherein the first driving module comprises a primary driving plate formed by a metal sheet, and a toothed rim mounted circumferentially on the primary driving plate, wherein such toothed rim incorporates sufficient mass to yield a moment of inertia for stabilizing the primary driving plate, so that no torque-applying circumferential plate is necessary for such first driving module.
