Arrangement for fixing a clutch to a crankshaft

摘要

For the coaxial fixing of an input component (7) of a clutch (1) to an output end (11) of a crankshaft (15), rotatable about an axis of rotation (13), of an internal combustion engine of a motor vehicle, it is proposed to insert an expansion element (39), for example a taper sleeve or an expanding spring assembly, between an outer clamping area (37) of the output end (11) and an inner clamping area (35) of the input component (7), which expansion element is clamped by means of a screw element (43) screwed into a central tapped opening (41) of the output end (11) for a press fit connection between the inlet component (7) and the output end (11). The screw element (43) is suitably designed so that it can be operated through the hub (25) of a clutch disc (5) of the clutch (1). The clutch (1) can thereby be fitted as constructional unit to the output end (11) of the crankshaft (15).
