Abstract (en)

[origin: WO2021148067A1] The invention relates to a torsional vibration damper (1) comprising an input part (2) accommodated on an internal combustion engine by means of securing screws and such that it can rotate about an axis of rotation (d), and an output part (3) arranged opposite the input part and such that it can rotate about the axis of rotation (d) and such that it is limited in relation to the effect of a spring device (4), and having access openings (46) arranged on an output hub (7) for screwing the securing screws (14), as well as having a torque limiting device (5) connected downstream of the spring device (4) on the output side. In order to be able to remove the torsional vibration damper from the crankshaft without an additional tool, despite an optionally triggered torque limiting device (5), an axially detachably toothing (40) that is axially pretensioned by a pretensioning means (41) is provided between the torque limiting device (5) and the output hub (7).
