Vibration damper for a drive train

A vibration damper for a drive shaft of a drive train, said drive shaft comprising a first shaft part, a second shaft part, and an elastically deformable damping part which is disposed between the first and second shaft parts and which is engaged by said first and second shaft parts in a rotationally locked manner;

• the first shaft part comprising a sleeve provided with radially inwardly oriented rotary drivers for the damping part;
• the second shaft part comprising an inner part provided with radially outwardly oriented rotary drivers for the damping part;
• said sleeve and said inner part being constructed and arranged such that an end region of the inner part is surrounded by the sleeve, and
• said damping part being disposed radially between the sleeve and the inner part and around said end region of said inner part, and comprising negative profiles in which respective rotary drivers of said sleeve and said inner part are received;
• wherein
• said damping part has an inhomogeneous structure or a discontinuous geometry,
• said damping part is constructed of at least two rings disposed one behind the other in the axial direction,
• said at least two rings have different elasticities, and
• said at least two rings are provided with different geometries.
