Abstract:
A torsional vibration damper, comprising:a first flywheel mass arrangement rotatable about an axis of rotation and having a first guide track;a second flywheel mass arrangement rotatable relative to said first flywheel arrangement about said axis of rotation and having a second guide track;a coupling mass arrangement for coupling said first flywheel mass to said second flywheel mass comprising a first bearing region movably arranged for translational motion along said first guide track for transmitting torsional forces to said first flywheel mass and a second bearing region movably arranged for translational motion along said second guide track for transmitting torsional forces to said second flywheel mass;said second bearing region arranged at a fixed distance from said first bearing region with respect to a plane oriented perpendicular to said axis of rotation and wherein said first and second guide tracks are operatively designed such that said coupling mass arrangement is transferable from a first position, in which said first bearing region is arranged in front of said second bearing region in a clockwise circumferential direction, to a second position, in which said first bearing region is arranged behind said second bearing region in said clockwise circumferential direction; anda further guide track arranged in opposition to and at a distance from at least a portion of said first guide track so that said first bearing region is movably guided between said further guide track and said first guide track, along one of said further guide track and said first guide track.
