ABSTRACT:
In order to secure the flywheel (5) of a motor vehicle friction clutch (3) to the output end of a crankshaft (23) of an internal combustion engine, it is proposed that the flywheel (5) is fastened to the output end of the crankshaft (23) by means of an axially detachable centric clamping arrangement (21). The flywheel (5) is hereby supported on a pipe end (37) of the crankshaft (23). Conical expansion elements (45), which may be axially displaced by means of a centric screw element (43) to generate radial clamping forces, are inserted into the centric cavity formed by the pipe end (37). The screw element (43) is structured in such a way that it may be screwed through the hub (27) of a clutch disc (9) of the friction clutch onto the crankshaft (23) by means of a screw attachment tool (51). The friction clutch (3) may thus be preassembled together with the flywheel (5) to form a structural unit before it is secured to the crankshaft (23) .
