Abstract: A wheel end assembly includes a first shaft supported on a knuckle secured to a vehicle frame, including first clutch teeth, a second shaft secured to the halfshaft, a coil, and a collar rotatably secured to the second shaft, axially displaceable relative to the first shaft, including second clutch teeth that alternately engage the first clutch teeth due to an electromagnetic field produced by energizing the coil and disengage from the first clutch teeth.

Abstract: A clutch mechanism includes a gear including clutch teeth, a housing having axial holes, including displaceable pins, each pin fitted in one of the holes, and a plate of forged powdered metal, the plate including second teeth, axial displacement of the pins causing axial displacement of the plate relative to the gear and the housing, and engagement of the second teeth with the clutch teeth.

Abstract: A clutch mechanism includes a coil of wire for producing an electromagnetic field, a locking ring secured against rotation within a case or housing, a gear engageable with the locking ring, and a lever that pivots in response to the electromagnetic field produced by energizing the coil causing the locking ring to engage the gear and hold the gear against rotation.

Abstract: A differential mechanism includes a case including first and second portions, the first portion including a first surface interrupted by recesses, the second portion including a second surface interrupted by second recesses, contacting the first surface, and secured to the first portion, a pin extending though the recesses, and a ring gear secured to the portions and overlapping the surfaces and the pin.

Abstract: A differential mechanism includes a case, a gear rotatable about an axis, a lock ring held against rotation relative to the case, a lever contacting the lock ring, and an electromagnetic coil that is displaced axially when energized, pivoting the lever, engaging the lock ring with the side gear, and preventing the gear from rotating relative to the case.
