Abstract
A torsional vibration damper for a clutch disk within a drive train of a motor vehicle includes an input part arranged around an axis of rotation (d), a spring device with at least three spring elements, an output part, and torque-transmitting intermediate elements. The output part can be rotated relative to the input part about the axis of rotation (d) to a limited extent against the spring device. The torque-transmitting intermediate elements are arranged between the input part and the output part for forcible radial displacement by means of cam mechanisms when the input part rotates relative to the output part. The spring device is arranged between the torque-transmitting intermediate elements, and a number of intermediate elements corresponds to a number of spring elements.
