  • Patent number: 11821469
    Abstract: 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.

  • Patent number: 11780316
    Abstract: 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.

  • Patent number: 11590836
    Abstract: A multiple disc clutch includes an axially displaceable outer disc hooked into an outer disc carrier to provide a first friction surface, and an axially displaceable inner disc hooked into an inner disc carrier to provide a second friction surface for a friction pairing with the first friction surface. The outer disc has an outer coupling element for coupling to the outer disc carrier and the inner disc has an inner coupling element for coupling to the inner disc carrier. The outer disc has an outer ring, the outer coupling element extends radially from the outer ring, and the first friction surface is connected to the outer ring by an outer leaf spring element; or the inner disc has an inner ring, the inner coupling element extends radially from the inner ring, and the second friction surface is connected to the inner ring by an inner leaf spring element.
