Abstract
A power transfer unit assembly for a vehicle is provided comprising a first input shaft providing rotational drive. A second input shaft is in communication with a gear train assembly which is in communication with a propshaft. A selective engagement element is movable between an engagement position wherein the second input shaft is placed in rotational communication with the first input shaft and a disengagement position wherein the second input shaft is disengaged from the first input shaft. An actuator assembly moves the selective engagement element into the engagement position for all wheel drive mode and into the disengagement position for two wheel drive mode.

A power transfer unit assembly for a vehicle comprising:
- a first input shaft providing rotational drive;
- a second input shaft;
- a gear train assembly in communication with said second input shaft
- a propshaft in communication with said gear train;
- a selective engagement element movable between an engagement position wherein said second input shaft is placed in rotational communication with said first input shaft and a disengagement position wherein said second input shaft is disengaged from said first input shaft;
- and
- an actuator assembly in communication with said selective engagement element, said actuator assembly moving said selective engagement element into said engagement position for all wheel drive mode, said actuator assembly moving said selective engagement element into said disengagement position for two wheel drive mode.
A power transfer unit assembly for a vehicle comprising:
- a first input shaft providing rotational drive;
- a second input shaft;
- a selective engagement element movable between an engagement position for all wheel drive mode wherein said second input shaft is placed in rotational communication with said first input shaft and a disengagement position for two wheel drive mode wherein said second input shaft is disengaged from said first input shaft.
A method of controlling a power transfer unit assembly comprising:
- providing rotational drive to a first input shaft;
- selectively moving a selective engagement element between an engagement position for all wheel drive mode wherein a second input shaft is placed in rotational communication with said first input shaft and a disengagement position for two wheel drive mode wherein said second input shaft is disengaged from said first input shaft.
