Abstract

A pendulum rocker damper with a rotation axis includes an input side with first and second input-side counter tracks, an output side with first and second output-side counter tracks, a stored energy source, and rocker elements disposed at opposite axial ends of the stored energy source. Each of the rocker elements has three axially offset partial tracks forming an input-side roller track and an output-side roller track. A first input-side rolling element is clamped between the first input-side counter track and a first input-side roller track and a second input-side rolling element is clamped between the second input-side counter track and a second input-side roller track. A first output-side rolling element is clamped between the first output-side counter track and a second output-side roller track and a second output-side rolling element is clamped between the second output-side counter track and a second output-side roller track.
