Abstract: Methods and systems are provided for operating an electromagnetic pulse disconnect assembly for selectively engaging two rotating components of a vehicle drivetrain. A disconnect assembly is needed that is not powered by vacuum diverted from an engine of the vehicle, as modern engines are being developed to reduce vacuum production and remove vacuum lines for powering peripheral devices such as disconnects. An electromagnetic pulse disconnect assembly is provided that operates via pulses of electrical current and includes an electromagnetic coil for translating a clutch ring assembly and a latching ring assembly to selectively couple two rotating components.

Abstract: Methods and systems are provided for a motorized disconnect operable to selectively engage and disengage two rotating components of a vehicle drivetrain. As one example, a motorized disconnect system is provided that operates via an electric motor and includes a shifter assembly with an oscillating gear track and cam profile for rotating the shifter assembly while moving it in an axial direction to selectively couple two rotating components.

Abstract: A wireless remote forms a two-way radio frequency (RF) communication network with a winch control module that allows the wireless remote to control both the winch and additional vehicle accessories through the winch control module. Further accessory control modules allow the control of more accessories utilizing the wireless remote by way of RF communication. Feedback from either the winch control module or the accessory control module is sent back to the wireless remote to allow the operator to view the current operating conditions of the winch or accessories.

Abstract: A four-wheel drive center disconnect electric actuator is provided. The actuator includes a one-way motor that actuates a cam mechanism for causing engagement and disengagement of the center disconnect. The actuator achieves improved reliability and efficiency through a less expensive construction than conventional actuators.

Abstract: An integrated air compressor and winch is provided that utilizes a single source of rotary motive power for driving both a winch drum and compressor mechanism. The integrated air compressor and winch is preferably provided with a gear case that is operable to provide an appropriate gear reduction for driving the winch drum while providing an appropriate drive speed for operating the compressor.

Abstract: A four-wheel drive center disconnect electric actuator is provided. The actuator includes a one-way motor that actuation of a cam mechanism for causing engagement and disengagement of the center disconnect. The actuator achieves improved reliability and efficiency through a less expensive construction than conventional actuators.

Abstract: A wheel hub assembly is provided including a movable clutch ring for selective engagement between an engaged and disengaged position for providing driving torque from an axle shaft to a wheel hub. The clutch ring is in full-time engagement with external clutch teeth of the axle shaft and is movable to an engaged position with external clutch teeth of a coupler that is secured to the wheel hub. Furthermore, the coupler is provided with a travel limiter for preventing the clutch ring from traveling beyond a predetermined desired position along the coupler.

Abstract: An interlock mechanism is provided for a wheel end disconnect device. The interlock mechanism is activated by negative pressure for engaging and disengaging a wheel hub from an axle shaft. Vacuum pressure is routed through a wheel bearing for activating the interlock mechanism.

Abstract: A bi-directional overrunning clutch and viscous transmission unit are combined in order to provide an on-demand four wheel drive system with having an improved construction.
