Kupplungseinrichtung und Antriebsstrang

The invention relates to a clutch device and a drive train. According to the invention, the clutch device comprises an inner plate support (10) and an outer plate support (30); at least one first friction plate (20), which is arranged on the inner plate support (10) in a torque-interlocking and axially movable manner; at least one second friction plate (40), which is arranged on the outer plate support (30) in a torque-interlocking and axially movable manner, wherein the first friction plate (20) and the second friction plate (40) together form a plate pack (50); a force exertion device for exerting an axial contact pressure on the friction plates (20 and 40); a hub element (60), which is connected to the inner plate support (10) by means of leaf springs (70) in a substantially rotationally fixed manner, wherein a first end (71) of each leaf spring (70) is mechanically fixed to the hub element (60) and the other, second end (72) thereof is mechanically fixed to the inner plate support (10); and wherein one of the connections of each leaf spring (70) is provided on a corresponding connecting component by means of a step pin (80), and the step pin (80) is guided in a manner movable axially in translation in the other component, connected by means of the leaf spring (70), and the end of the step pin (80) opposite the fixing to the component has a pin head (81) having a greater radial extent than an opening (11) in the component guiding the step pin (80) in translation. The invention thus relates to a clutch device which ensures centering of the leaf spring core (90) in relation to the counter-plate (100) and facilitates assembly.
