Abstract

A vibration damping device for a drive system of a motor vehicle includes a base body arranged for rotating about an axis of rotation and a deflection mass arrangement arranged in said base body and having at least one deflection mass and a deflection path associated with the at least one deflection mass and along which the deflection mass is movable during rotation of the base body about the axis of rotation. The deflection path has a vertex area at a position furthest from the axis of rotation and deflection areas on both sides of the vertex area extending from the vertex area to ends areas. The deflection areas have a decreasing distance from the axis of rotation (A) proceeding from the vertex area toward their end areas. A braking arrangement acts in the end areas of the deflection areas for gradually slowing the approach of the at least one deflection mass to a respective end area of the deflection path.
