  • Patent number: 11131350
    Abstract: A coupling for connecting an input shaft to an output shaft through a bi-directional overrunning clutch assembly. A portion of the input shaft is located within an internal cavity of the output shaft. The bi-directional roller clutch assembly selectively connects and disconnects the input and output shafts from one another. A drive plate is disposed about and attached to a portion of the input shaft so as to rotate in combination therewith. The drive plate is rotationally connected to a clutch housing of the clutch assembly such that rotation of the input shaft produces corresponding rotation of the clutch housing. A torsion spring is positioned within a spring retainer and engaged with at least one of either the spring retainer or the clutch housing. An engagement control assembly controls the engagement and disengagement of the clutch assembly and a coil housing mounted in the cover and a coil mounted in the coil housing, the coil is connected to a switch for controlling the supply of current to the coil.

    Abstract: A clutch actuation device selectively engages a clutch. The clutch actuation device includes two plates, at least one of which being able to rotate relative to the other. Between the two plates is a rounded member, such as a ball, housed within opposing grooves in the respective plates. As the plates rotate relative to one another, the rounded member forces the plates to separate axially from one another. This can engage the clutch. A third plate is placed at a location axially spaced from the second plate. The third plate limits movement of the second plate when moving to the extended position, assuring the second plate does not over-translate axially. A resilient member may be provided between the third plate and a housing. The resilient member can be tuned to properly inhibit the axial movement of the second and third plates according to the packaging constraints.

  • Patent number: 10077811
    Abstract: A lubrication system (400) for a transfer case (200) includes a pump (228) selectively supplying a working fluid to a fluid reservoir of an actuator (226) configured to apply force to a clutch assembly (214) to cause the clutch assembly (214) to move between a disengaged position and an engaged position. The lubrication system also includes a relief valve (302) having a relief valve inlet fluidly coupled to the fluid reservoir of the actuator (226) which opens to receive the working fluid based on a threshold pressure level of the working fluid in the fluid reservoir. The lubrication system also includes a trough (306) fluidly coupled to a relief valve outlet of the relief valve (302). The trough (306) carries the working fluid from the relief valve outlet to a bearing assembly (227) associated with at least one of an input shaft (204) and a primary output shaft (206) of the transfer case (200) when the clutch assembly (214) is in the disengaged position.

  • Patent number: 10066677
    Abstract: The invention relates to a clutch device for a drivetrain of a motor vehicle, including a pressure plate which is preferably displaceable in the axial direction of the clutch device, wherein the pressure plate, in a coupled position of the clutch device, presses a clutch disk against a counterpressure plate that can be connected to a crankshaft of an internal combustion engine, and including an actuating device which has a displaceable actuating piston. The displacement position of the actuating piston defines a position of the pressure plate and the actuating piston can be driven by a drive unit of the actuating device in order to displace the pressure plate between the coupled position and an uncoupled position. The drive unit has at least one pump, and the at least one pump is accommodated in a pump seat housing and the pump seat housing is connected to the counterpressure plate in such a way as to rotate therewith.

  • Patent number: 9476464
    Abstract: An electromagnetic driving device includes a driving disc, and also a first driving device, a second driving device and a first electrical control device. When the first electrical control device is energized, the first electrical control device drives the first driving device such that the second driving device is disengaged from the driving disc. When the first electrical control device is de-energized, the first electrical control device drives the first driving device such that the second driving device is engaged with the driving disc. The device aims to provide an electromagnetic driving device able to operate and serve the function of driving even if a power supply system of an electromagnetic clutch malfunctions or a sudden power cut occurs, avoiding the series of adverse effects caused by the failure of the electromagnetic clutch.
