Abstract
A torsional vibration damper includes a rotational axis, an input part mounted about the rotational axis, an output part rotatable about the rotational axis to a limited extent relative to the input part; a spring device opposing rotation of the output part relative to the input part, a first cam mechanism, and a first intermediate element. The first intermediate element is arranged for radial displacement by the first cam mechanism when the output part rotates relative to the input part. The first intermediate element has a first intermediate element first part, and a first intermediate element second part. In an example embodiment, the damper includes a second cam mechanism and a second intermediate element arranged to be radially displaced by the second cam mechanism when the output part rotates relative to the input part. The spring device is arranged between the first intermediate element and the second intermediate element.
