  • Patent number: 9752625
    Abstract: Dual clutch including two clutch units acting in a force-fitting manner and mounted on a common clutch hub in a rotationally fixed and axially movable manner, a pressure disk arrangement retained between the clutch units on the clutch hub in an axially fixed manner and including two axially movable pressure pistons each of which can be ventilated by a compression spring arrangement positioned in the clutch hub. Each compression spring arrangement includes multiple compression springs, each of which is arranged in a recess of the clutch hub. Each recess is introduced into the clutch hub as an axially extending blind hole. The pressure disk arrangement is received in a radial groove of the clutch hub, the groove being radially and/or axially spaced from the blind holes.

  • Patent number: 9200682
    Abstract: A synchronization unit for a positive dual clutch. The synchronization unit has a sleeve carrier that is axially and rotationally fixed to an output shaft and a shifting sleeve that is rotationally fixed and axially displaceable relative to the sleeve carrier. The synchronization rings of a synchronization clutch on the sleeve carrier side and the sleeve carrier comprise axially interlocked circumferential segments.

  • Patent number: 8893870
    Abstract: A dual shift coupling including two operatively connected coupling units mounted on a shared, integrally formed inner body in a rotationally fixed and axially movable manner. Further, a multi-part pressure disk is arranged between the coupling units in an axially fixed manner and is supported by the inner body, and has two axially movable pressure pistons ventilated by respective pressure spring assemblies arranged in the inner body. A radial notch for accommodating the pressure disk is provided in the inner body, wherein the radial depth of the notch extends at least to radial inner wall segments of recesses for the pressure spring assemblies. Each pressure spring assembly has a plurality of pressure springs which rest on the inner side of the pressure disk relative to the axis.

  • Publication number: 20130206537
    Abstract: A friction clutch or brake having an axially movable pressure piston arrangement and at least one annular shoulder, to which pressure can be applied by the pressure piston arrangement. The pressure piston arrangement has at least two pistons, which can be applied to the at least one annular shoulder in succession and in stages in a pressure-dependent manner.
