Abstract (en)

[origin: WO2019196984A1] The invention relates to a torsional vibration damper (1), in particular for a clutch disc within a powertrain of a motor vehicle, comprising an input part (2) which is mounted about a rotational axis (d) and an output part which can rotate about the rotational axis (d) to a limited degree relative to the input part (2) against the effect of a spring device (8), comprising at least two torque-transmitting intermediate elements (3) which are arranged between the input part (2) and the output part (19) and which are arranged so as to be forcibly moved in a radial direction by means of cam mechanisms (4, 5) in the event of a relative rotation between the input part (2) and the output part (10). The spring device (8) is arranged between the at least two intermediate elements (3). The invention is characterized in that each intermediate element (3) is designed in two parts.
