  • Patent number: 10544838
    Abstract: The invention relates to a clutch assembly for a powertrain of a motor vehicle, comprising at least one clutch and at least one actuation device. The clutch can be brought into an open position and/or a closed position by means of the actuation device such that a first sub-region of the powertrain and a second sub-region of the powertrain are decoupled and/or coupled. The actuation device comprises an actuation element and a control element which is connected to the clutch. The control element is arranged in a guidable manner in a guide slot with respect to the actuation element, and the control element is held in the region of the guide slot by means of an energy storage element, which counteracts a movement of the control element out of a first stop position along the guide slot, in the closed position of the clutch. The invention also relates to a method for decoupling the first sub-region of the powertrain from the second sub-region of the powertrain by means of the clutch assembly.

  • Patent number: 10047802
    Abstract: Clutch for a motor vehicle, preferably for engaging and disengaging a drivetrain for all-wheel drive vehicles, comprising a first shaft, a second shaft coaxially arranged with the first shaft, a clutch sleeve, which is displaceable in an axial direction relative to the first shaft and the second shaft and which brings about a positive coupling or decoupling of the first shaft and the second shaft, together with a coil to which current can be applied, wherein the clutch sleeve is arranged, torsionally fixed to the first shaft, and wherein the coil to which current can be applied is arranged coaxially with the axial direction, wherein the clutch sleeve to which current can be applied can be displaced in an axial direction through the application of current to the coil.

  • Patent number: 9863525
    Abstract: A clutch-controlled transfer gear having a drive shaft which is mounted so as to be rotatable by way of at least one drive shaft bearing, a primary shaft which is mounted so as to be rotatable by way of at least one primary shaft bearing, a secondary shaft which is arranged with an axial offset with respect to the drive shaft and which is mounted so as to be rotatable by way of at least one secondary shaft bearing, a transfer mechanism which is arranged between secondary shaft and drive shaft and bridges the axial offset thereof, and a clutch which is arranged between the drive shaft and an offset gear, by means of which clutch the secondary shaft is, for the operation thereof, coupled to the drive shaft and, for the deactivation thereof, decoupled from the drive shaft, as required.
