Abstract
A wheel end disconnect assembly includes an axle shaft, a wheel hub, and a wheel end disconnect clutch. The axle shaft has a first dog clutch spline and the wheel hub has a second dog clutch spline. The wheel end disconnect clutch has a dog clutch sleeve and a rocker pin. The dog clutch sleeve has a third dog clutch spline engaged with one of the first or second dog clutch splines and arranged to selectively engage and disengage from the other of the first or second dog clutch splines, and a first spiral groove. The rocker pin has a first pin end arranged to selectively engage and disengage from the first spiral groove to axially displace the dog clutch sleeve. The first dog clutch spline and the second dog clutch spline may both be outer splines, and the third dog clutch spline may be an inner spline.
