1. A torsional vibration damper comprising:
an input part for introducing a torque,
a first cam mechanism;
an intermediate element coupled to the input part via the first cam mechanism such that a relative rotation between the input part and the intermediate element is converted into a linear movement of the intermediate element radially inward or radially outward;
a compression spring engaged with the intermediate element;
a second cam mechanism, separate from the first cam mechanism;
an output part for discharging a vibration-damped torque, coupled to the intermediate element via the second cam mechanism such that a linear movement of the intermediate element is converted into a relative rotation between the output part and the intermediate element; and
a first frictional element for friction damping, pressed against the intermediate element or the output part.
