ABSTRACT:
A vibration damper, for example, a multistage torsion vibration damper, including at least two coaxially disposed damper assemblies, each of them including at least one input component and one output component and being disposed on different diameters, a first damper assembly being disposed on the outside in a radial direction and configured as a series damper, including at least two dampers connected in series and coupled via an intermediate flange, and a second damper assembly being disposed on the inside in the radial direction. The intermediate flange includes at least two annular disk-shaped elements disposed at a distance in the axial direction and extending on both sides of the output component of the first damper arrangement at least into the portion of the outer circumference of the output component of the first damper assembly, each including openings extending in the circumferential direction.
