Abstract:
A vibration damping device for a motor vehicle drive system, comprising:a base body arranged for rotating about an axis of rotation; and a deflection mass arrangement arranged in said base body and having a plurality of deflection masses and corresponding deflection paths, said deflection masses being arranged for moving freely along said deflection paths during rotation of said base body about said axis of rotation, wherein each of said deflection paths has a vertex area and deflection areas on opposing sides of the vertex area, the deflection areas extending from the vertex area to respective end areas and having a decreasing distance to said axis of rotation proceeding from the vertex area to said end areas, and wherein said deflection mass arrangement further comprises a braking arrangement operatively arranged for gradually slowing an approach of each said deflection mass toward said end areas of said deflection path, said braking device comprising a stop ring arranged concentrically on said base body and having a plurality of wedges with radial outward extending tips, said plural wedges forming a star-shaped outer contour of said stop ring, each of said plural wedges comprising first and second stop areas arranged on opposing sides of said tip.
