Claim 12:
13. A shift actuator for a power transfer unit, the shift actuator comprising:
a motor that drives a drum assembly having a disconnect track and a range track, wherein operation of the motor rotates the drum assembly about a rotational axis, wherein the drum assembly includes a drum cam and a drum shaft, wherein the drum cam and the drum shaft are rotationally fixed with respect to one another, and wherein the drum cam is axially slidable relative to the drum shaft;
a fork rod that is positioned parallel with the rotational axis and between the motor and the drum assembly;
a disconnect fork that extends between the disconnect track and the fork rod;
a range fork that extends between the range track and the fork rod; and
a position sensor that is in communication with the motor and each of the disconnect fork and the range fork, wherein:
operation of the drum assembly slidably operates the disconnect fork through the disconnect track and along the fork rod relative to the position sensor;
operation of the drum assembly slidably operates the range fork through the range track and along the fork rod and relative to the position sensor; and
the position sensor communicates with a controller that is in communication with the motor to stop operation of the motor and the drum assembly when the disconnect fork and the range fork define an actuating position relative to the drum assembly.
