US Patent 9302581 All-wheel drive driveline with disconnecting axle

A disconnecting driveline component can include a shaft coupled to one of a pair of output members of a differential. A clutch input can be coupled for rotation with one of a ring gear and the one of the output members. A clutch output can be coupled for rotation with one of a differential case and the shaft. A collar can be axially-slidable between a first position, where the collar couples the clutch input and the clutch output to transmit rotational power therebetween, and a second position where the collar is rotatably decoupled from one of the clutch input and the clutch output. A pilot input can be non-rotatably coupled to the clutch input. A pilot output can be fixed to the clutch output. An electromagnet can draw the pilot input into frictional engagement with the pilot output when the collar is in the second position.
