Plunger Disconnect Patents (Class 192/69.2)
  • Patent number: 10421537
    Abstract: A locking mechanism for a driveshaft disconnect coupling includes an input jaw member defining a rotation axis, an output jaw member connectable to the input jaw member for common rotation with the input jaw member, and a cartridge assembly. The cartridge assembly is fixed to the input jaw member, includes a pin, and defines a pin movement axis. The pin is movable along the pin axis between a radially inner position and a radially outer position, the pin being disengaged from the output jaw member in the radially inner position and the pin being engaged to the output jaw member in the radially outer position.

  • Publication number: 20140299438
    Abstract: A drive unit disconnect mechanism is operable to transmit or disconnect power from a vehicle power source to a driven unit, and can be disengaged by multiple methods depending on how much force is required to separate the internal components of the mechanism. In a first, relatively quicker method, a handle is pulled axially away from the hub to withdraw and internal gear from splined engagement with a corresponding driven gear. In a second, relatively slower method, the handle is rotated to threadably withdraw the entire disconnect mechanism from the hub, which in turn withdraws the internal gear from splined engagement with the driven gear. The quicker method is desirable in most instances, but the slower method allows disconnection of the driven unit from the vehicle power source when gear pressure prevents or impedes the quicker method.

  • Patent number: 8225919
    Abstract: A drive arrangement comprising a drive shaft, a clutch arrangement operable, upon axial movement of the drive shaft occurring, to interrupt drive to the drive shaft, an axially movable interrupt shaft, a gear arrangement whereby the interrupt shaft is driven for rotation by the drive shaft at a speed slower than the rotary speed of the drive shaft, a disconnect device operable to cause axial movement of the interrupt shaft, and a transmission device for transmitting axial movement of the interrupt shaft to the drive shaft.

  • Patent number: 8162122
    Abstract: A drive disconnect device for releasably connecting an electrical generator to a drive shaft, the drive disconnect device comprising an output shaft and at least one drive transfer element movable from a first position where it drivingly connects the drive shaft and the output shaft to a second position where the driving connection is removed, wherein operation of the disconnect device causes the electrical generator to become electrically isolated or excitation for the generator to be inhibited.

  • Publication number: 20100283341
    Abstract: A clutch member for use in a generator clutch has actuation structure including a face with a ramp. The ramp has a ramp angle of between 6.2° and 6.4°. The clutch member may be a sliding decoupler shaft. In addition, a rotor and a generator including the clutch members are also disclosed and claimed.

  • Patent number: 7182193
    Abstract: A drive disconnect device is provided in which a drive transfer element (12) is axially movable with respect to input and output shafts (2, 14) so as to selectively disconnect them. A collar (50) is disposed in spaced apart configuration around the drive transfer element so that they do not touch except when the disconnect device is operated to disconnect the drive. When the disconnect operation is initiated, force is provided from a resilient element (56) to move the drive transfer element.
