Torsional vibration damping assembly

Abstract

The disclosure relates to a torsional vibration damping assembly comprising a deflection mass carder capable of rotation about a rotational axis and deflection masses mounted following one another in a circumferential direction on the deflection mass carrier and deflectable from a basic relative position, wherein the radial position of the deflection masses with respect to the rotational axis changes on deflection from the basic relative position, with each deflection mass being mounted deflectably in both circumferential directions from the basic relative position by coupling formations on the deflection mass carrier, with a resiliently deformable stop formation being provided and assigned to each deflection mass to haft a deflection movement of the deflection mass once a stop deflection has been reached, with the resiliently deformable stop formation comprising a resilient stop material which is fixedly mounted with respect to the deflection mass carder, with the following ratio R being applicable in the assignment to each deflection mass: R=VE/E wherein VE is an effective stop material volume assigned to a deflection mass on reaching the stop deflection by deformation of the resilient stop material and E is an impact metric relative to the kinetic energy of a deflection mass on reaching the stop deflection, and wherein the following applies for the ratio R: 0.15×10−3 m2/kg≤R≤0.6×10−3 m2/kg.
