Hybrid transfer case

A transfer case comprising:

• a primary output shaft that receives torque from a drive source external to the transfer case, the primary output shaft providing a primary torque output of the transfer case;
• an electric motor having a rotor and a stator that are internal to the transfer case;
• a planetary gear set having a sun gear rotatably fixed to the rotor, a ring gear, planet gears arranged radially between and engaging the sun gear and the ring gear, and a planet carrier coupled to the planet gears and rotatably fixed to the primary output shaft, wherein the ring gear is selectively groundable for selectively transferring torque between the electric motor and the primary output shaft;
• a housing and a locking ring, wherein the ring gear is selectively grounded to the housing with the locking ring;
• wherein the locking ring is movable axially between a first position in which the locking ring grounds the ring gear to the housing and a second position in which the locking ring allows the ring gear to rotate freely of the housing;
• and
• an actuator system having the locking ring, a barrel cam, and a fork assembly extending between the locking ring and the barrel cam, wherein rotation of the barrel cam moves the locking ring with the fork assembly between the first position and the second position.
