A mass damper system with a damper mass carrier having guide paths for receiving damper masses. The guide paths initiate swiveling movement at the damper masses around a center of mass during deflection of the damper masses. String lengths of imaginary string pendulums predetermine a position of respective coupling element configure the guide paths and the path curve is based on a first radial portion that extends from a central axis of the damper mass carrier to a connection point of a second radial portion and the second radial portion extends from the first radial portion to the center of mass. A ratio value is formed from a swiveling angle of the damper mass and its oscillation angle. A coupling element position in relation to the string length is determined by this ratio value.

Absorber system with guideways and method for the arrangement of guideways on an absorber system

A constructional unit for a hybrid powertrain of a motor vehicle includes: an electric machine with a stator and a rotor, wherein the rotor is configured to transmit a torque to the powertrain; a clutch arrangement with at least one clutch actuation unit, wherein the clutch arrangement is configured to decouple an internal combustion engine from the powertrain, the internal combustion engine being provided parallel to the electric machine for transmitting a torque; and a vibration absorber apparatus configured to reduce vibrations in the powertrain.
