Abstract: A vehicle differential disconnect assembly includes a differential case and a differential gear set carried within the differential case. The differential gear set includes a differential carrier rotatably supported within the differential case. A clutch ring includes interior spline splines engaged with exterior splines of the differential case and being movable to engage exterior splines on the differential carrier. An actuator assembly includes a solenoid with a plunger that engages a rocker that is pivotally mounted to a support structure and connected to the plunger. A shift fork is operably engaged with the clutch ring and slidably mounted for translation along an axis. The shift fork includes an engagement feature for receiving an end of the rocker, wherein activation of the actuator causes pivotal movement of the rocker to cause the shift fork to translate along the axis.

Abstract: The present disclosure describes an apparatus, and method of operation for an axial coupling that includes a shift linkage having a first end and a second end, the shift linkage configured to pivot between a first position and a second position. The axial coupling further includes a first solenoid affixed to the first end of the shift linkage, and actuating the first solenoid pivots the shift linkage between the first and second positions. A latch is configured to engage with the shift linkage retaining the shift linkage in the first position when engaged and a second solenoid positioned to contact the latch, that when energized, pivots the latch into and maintain the latch in an engaged position.

Abstract: An actuator for a wheel end disconnect system includes a housing and a solenoid mounted to the housing, the solenoid is actuatable to move a plunger in a fore and aft direction. A rocker is pivotally mounted to the housing and is connected to the plunger. A shift fork slidably mounted on a translation pin extending from the housing, the shift fork including a channel for receiving an end of the rocker, wherein activation of the solenoid causes pivotal movement of the rocker to cause the shift fork to translate along the translation pin.

Abstract: A pulling tool is provided with a rotatable drum having a cable wound thereon. A motor is drivingly connected to the rotatable drum and the rotatable drum and motor are disposed within a unique housing structure. The rotatable drum is driven by a planetary gear system that is disposed within the rotatable drum to provide a compact assembly. A belt and pulley system is provided for delivering torque from the motor to the planetary gear system. The rotatable drum is provided with a two-piece stepped construction that allows the planetary gear system to be assembled within the drum and allows for the initial wraps of a cable around the smaller diameter portion of the stepped drum.
