  • Patent number: 9157494
    Abstract: A drive system may provide centrifugally driven clutch members into engagement and disengagement using weights between an interface of the clutch members. The weights maybe disposed in races between the clutch members. The weights may move centrifugally within the races pushing the clutch members apart during rotation of an input drive shaft. In some embodiments, two clutch members may provide the engagement and disengagement of the input drive shaft power to a drive output member and a third clutch member may be configured to engage the two clutch members during drive engagement. The third clutch member may be configured to disengage from the two clutch members as a failsafe during, for example, an overspeed condition or a jammed clutch interface.

  • Patent number: 9151368
    Abstract: An actuator that causes a mode clutch to shift between an engaged position and a disengaged position is provided. The actuator comprises a motor having an output. A shift cam is caused to rotate based on the output of the motor. The shift cam has a cam profile surface. A cam follower rides along the cam profile surface upon rotation of the shift cam. Movement of the cam follower causes movement of a mode fork resulting in the mode clutch shifting between the engaged and disengaged positions. A sensor outputs a voltage to a controller based on a physical location of the cam follower. The controller activates the motor based on the voltage.

  • Patent number: 9151340
    Abstract: A clutch device for a clutch system has a nose cap and a piston that is movable in an axial direction with respect to the nose cap. A seal disposed in the axial direction between the nose cap and the piston automatically locks the clutch device when a threshold amount of wear has accrued in a friction interface of the clutch device. If the seal is not compressed in the axial direction, then a pressurized fluid can flow past the seal and the piston is displaced in the axial direction away from the nose cap. If the seal is compressed in the axial direction, then the pressurized fluid does not flow past the seal and the piston is not displaced in the axial direction away from the nose cap.

  • Patent number: 9151345
    Abstract: A transmission clutch module including inner and outer races, a plurality of race engaging pawls and an actuator ring incorporates an actuator having a rotatable spool header adapted to rotate an attached actuator lever between at least two angular positions. The actuator lever moves the actuator ring to selectively block the pawls so inner and outer races may freewheel relative to one another in at least one operating mode. The actuator may be electric or hydraulic powered, and may be spring-biased to a default position in event of power failure. An elongated axially moveable plunger is secured to and supported within a piston at a first end, and has a radially extending pin at its second end. A fixed spool sleeve to which the spool header is supported includes a helical slot through which the pin extends. As the plunger moves reciprocally, the pin undergoes both translational and rotational movement.

  • Patent number: 9133890
    Abstract: A friction clutch, for example, a dual clutch, having traction mode and power take-off, with a pressure plate that is axially pre-stressed, applying a load to a cup spring, against an opposing pressure plate while tensioning friction linings of a clutch plate, the pressure plate being displaceable against the effect of the cup spring by means of pressure levers distributed along the periphery that are rotatably arranged by means of first pivot joints on knee levers that are axially stressed by a disengaging mechanism and have a specifiable axial distance relative to the disengaging mechanism. In order to achieve a constant transmissibility of the existing torque in traction mode over the service life when there is wear of the friction linings, an automatic adjusting device is provided in series with the adjusting screws between the pressure levers and the pressure plate.

  • Patent number: 9121454
    Abstract: A locking member for controllably transmitting torque between first and second coupling members of a coupling assembly is provided. The locking member includes projecting inner and outer pivots which extend laterally from a main body portion for enabling pivotal motion of the locking member about a pivot axis which intersects the pivots. The pivots are sized, shaped and located with respect to the main body portion to allow frictional engagement of an end surface of the outer pivot with an outer wall of a pocket to occur near the pivot axis during rotation of the first coupling member and the locking member above a predetermined RPM thereby reducing overall moment on the locking member about the pivot axis that has to be overcome to move the locking member between the engaged and disengaged positions.
