Abstract:
A torsional vibration damper comprising:a driving-side transmission element; a driven-side transmission element which is rotatable relative to the driving-side transmission element; a damping device operatively connected with the driving-side transmission element; a gearset associated with the damping device, said gearset having a shift mechanism and comprising at least a driving-side gearset element and a driven-side gearset element wherein introduced torsional vibrations can be transmitted to the damping device with gear shifting by means of the gearset, said driving side gearset element and said driven side gearset element having a working connection and said shift mechanism can cancel the working connection between the driving-side gearset element and the driven-side gearset element, wherein said driving side gearset element comprises an axial spring, said axial spring having an axial dimension and a radial dimension, said axial and radial dimensions remaining essentially constant at low rotation rates and changing at increasing rotation rates.
