A multi-plate clutch includes an outer plate mounted on a radial outside and axially displaceable, an inner plate mounted on a radial inside and axially displaceable, and a plurality of leaf springs. The plurality of leaf springs is distributed around an outer circumference of the outer plate to mount the outer plate in a torque-transmitting manner on a rotor pot, or the plurality of leaf springs is distributed in an inner circumference of the inner plate to mount the inner plate in a torque-transmitting manner on a driving ring. In an example embodiment, the multi-plate clutch is a dry multi-plate clutch for a hybrid drivetrain. In an example embodiment, the multi-plate clutch includes a plurality of outer plates and a plurality of inner plates.

A hybrid module for a drive train of a motor vehicle includes an electrical machine, a dry friction clutch for coupling the electrical machine with the drive train, an input shaft arranged to be coupled to an internal combustion engine of the motor vehicle, and an output shaft arranged to be coupled to a vehicle transmission of the motor vehicle. The dry friction clutch is designed to lead away or secure wear debris of the dry friction clutch. The hybrid module may be arranged as a P2 hybrid module within the drive train between an internal combustion engine side of the motor vehicle and a vehicle transmission side of the motor vehicle. The dry friction clutch may be a dry multi-disk clutch.

A clutch device for a drive train of a motor vehicle includes a torsional vibration damper with an output side, a disconnect clutch with a clutch component, and a fastening unit releasably connecting the disconnect clutch to the torsional vibration damper. The fastening unit includes a first toothing region fixed on the clutch component, a second toothing region fixed on the output side and positively rotationally connected with the first toothing region, and a clamping element. The clamping element is arranged to preload the first toothing region relative to the second toothing region in a circumferential direction with a preloading force, and preload the output side relative to the clutch component with an axial contact pressure.

A friction clutch for a drivetrain of a motor vehicle includes and input part, an output part, a spring device, a pressure pot, and a connecting means connecting the pressure pot to the inner-plate carrier. The input part includes an outer-plate carrier which is rotatable about an axis of rotation by a drive motor, and an outer plate rotationally fastened to the outer-plate carrier. The input part includes a rotor carrier, an inner-plate carrier separate from the rotor carrier, and an inner plate rotationally fastened to the inner-plate carrier. The spring device is for bracing the outer plate and the inner plate together with a pressing force to close the friction clutch. The connecting means includes an actuating surface via which the friction clutch can be actuated by an actuating device.

A clamping device for a shaft-hub connection in a torque-transferring device in a drive train of a vehicle. The connection is an axial spline connection between an externally toothed shaft and an internally toothed hub. An externally toothed ring is provided for clamping the shaft and hub, wherein the externally toothed ring includes an annular body having external teeth. Fastening tongues of leaf-spring-type design are provided on and extend from the radially inner side of the annular body. Outer ends of the leaf-spring-type fastening tongues are attached to the shaft, and the teeth of the toothed ring mesh with teeth of the hub. By rotating the toothed ring against a force provided by the fastening tongues, a clamping force is produced on the shaft-hub connection in the assembled state and is introduced into the shaft-hub connection through the teeth and fastening tongues.

A clutch device, in particular a booster clutch device, including at least a clutch flange and a clutch hub, which are arranged coaxially to each other and are coupled with each other by means of a spring device having a multi-stage spring characteristic is provided. The clutch flange forms a plate basket to hold lamellae for a clutch. The clutch device shown and described here is less complex than corresponding clutch devices which are assumed to be known, functions of the plate basket and the torque sensor being combined. That makes fewer parts necessary, but they continue to have the same functions. The construction is less complex, assembly requires less effort, and the costs are reduced accordingly. The clutch device is flexibly adaptable to different requirements.
