PENDULUM ROCKER DAMPER WITH AN AXIS OF ROTATION FOR A DRIVE TRAIN

The invention relates to a pendulum rocker damper (1) with an axis of rotation (2) for a drive train (3), comprising at least the following components: a primary side (4) that is torque-transmittingly connected to a first outer connection (6); at least one rocker element (8); at least one first energy storage element (9) for exerting a first pretensioning force (10); at least one roller (11, 12); and a secondary side (5) that is torque-transmittingly connected to a second outer connection (7), wherein the at least one roller (11, 12) is mounted such that it can roll on a rocker-side roller track (13) and a outer roller track (14) that is complementary to the rocker-side roller track (13), and same can be pretensioned against the roller tracks (13, 14) using the first pretensioning force (10) of the at least one first energy storage element (9). The pendulum rocker damper (1) is primarily characterised in that at least one second energy storage element (15) is provided in the roller (11, 12) or in at least one of the roller tracks (13, 14) for exerting a second pretensioning force (16), wherein the roller (11, 12) is pretensioned against at least one of the roller tracks (13, 14), perpendicular to the track, at least in the resting position of the first energy storage element (9), using the second pretensioning force (16). Using the pendulum rocker element according to the invention, interfering noise can be reduced and a sliding of a roller can be safely prevented by shifting the natural frequency into non-critical ranges.
