Abstract

The present invention relates to a flywheel (1) for a drive train (2) of a motor vehicle (3), with a rotation axis (5) extending along an axial direction (4) and arranged coaxially thereto with a main flywheel mass (7) forming an input side (6), a torque limiting device (8), a torsional vibration damper (9) and a hub forming an output side; wherein the hub is designed in two parts and comprises an annular first hub part (10) with a plurality of stop surfaces (12) acting against a circumferential direction (11) for the torsional vibration damper (9), and an annular second hub part (14) arranged in a radial direction (13) within the first hub part (10);wherein the first hub part (10) and the second hub part (14) form a rotationally fixed connection (15) with respect to the circumferential direction (11) in an operating state of the flywheel (1) and are preloaded together with respect to the axial direction (4).
