Abstract:
1. A drivetrain for an all-wheel drive motor vehicle, the drivetrain comprising: a differential input that is rotatable about a first axis; a differential assembly having a differential case and a differential gearset, the differential case being coupled to the differential input for common rotation about the first axis, the differential gearset being housed in the differential case and being configured to receive rotary power therefrom, the differential gearset having a pair of differential output members; a power take-off unit (PTU) having an input spindle, a spool, a ring gear, and a dog clutch, the input spindle being coupled to the differential case for common rotation about the first axis, the spool being disposed concentrically about the input spindle, the ring gear being fixedly coupled to the spool, the dog clutch having first and second dog members, the first dog member having a first set of dog teeth that are disposed circumferentially about the first axis, the first dog member being fixedly coupled to one of the spool and the input spindle, the second dog member having a second set of dog teeth that are disposed circumferentially about the first axis, the second dog member being non-rotatably but axially slidably coupled to the other one of the spool and the input spindle, the second dog member being movable along the first axis between a first position, in which the second set of dog teeth are disengaged from the first set of dog teeth to thereby inhibit transmission of rotary power between the input spindle and the spool, and a second position, in which the second set of dog teeth are engaged to the first set of dog teeth to thereby permit transmission of rotary power between the input spindle and the spool; and a shaft member coupled for rotation with one of the differential output members and extending through the input spindle.
