Torsional Vibration Damper And Start-Up Element

A torsional vibration damper configured to damp a vibration component of a rotational movement, comprising:

• an input;
• an output;
• an intermediate mass arranged between the input and the output;
• a first plurality of spring elements coupled between the input and the intermediate mass that forms a first stage of the torsional vibration damper, the first stage of the torsional vibration damper has a progressive first characteristic with at least one transition point;
• a second plurality of spring elements coupled between the intermediate mass and the output that forms a second stage of the torsional vibration damper, the second stage of the torsional vibration damper has a progressive, second characteristic with at least one transition point;
• and
• at least one damper mass configured to perform an oscillation depending on the rotational movement to damp the vibration component of the rotational movement,
• wherein all of the transition points of the first characteristic of the first stage of the torsional vibration damper and the second characteristic of the second stage of the torsional vibration damper are spaced apart from one another with respect to torque.
