5. The disconnect system of claim 1 , wherein the clutch ring includes external teeth arranged around a circumference thereof;

wherein the disconnect system further comprises a speed sensor arranged to detect a rotational speed of the clutch ring, wherein the speed sensor detects the external teeth of the clutch ring to determine a rotational speed of the clutch ring.

6. The disconnect system of claim 1 , wherein the clutch ring includes a tapered surface that defines a reduced axial width of the clutch ring as the clutch ring extends radially outward.

7. The disconnect system of claim 1 , further comprising a clevis coupled between the solenoid actuator and the shift fork, wherein the clevis includes a yoke recess to receive a portion of the shift fork,

wherein the yoke recess defines a width taken relative to a transverse axis, the width of the yoke recess at a lateral most portion of the yoke recess being greater than the width of the yoke recess at a center of the yoke recess.

8. The disconnect system of claim 1 , further comprising an annular bumper ring arranged between the clutch ring and an end surface of the drive member, wherein the annular bumper ring is configured to prevent or inhibit overtravel of the clutch ring.

9. The disconnect system of claim 1 , wherein the solenoid actuator is configured as a bi-stable solenoid actuator;

wherein the bi-stable solenoid actuator is configured to maintain a position of the shift fork, and thereby the clutch ring in either the engaged or disengaged position, without power applied to the bi-stable solenoid actuator.

10. The disconnect system of claim 1 , wherein the position sensor is disposed entirely within the housing cover.

11. A disconnect system for selectively coupling or disconnecting a drive member and a driven member, the disconnect system comprising:

a housing;

a housing cover configured to couple to the housing;

a clutch ring rotationally coupled to the drive member, the clutch ring defining a rotational axis and including internal teeth, the internal teeth of the clutch ring being engaged with external teeth of the drive member;

an actuator arranged within the housing;

a shift fork coupled to the clutch ring and movable by the actuator, such that pivotal movement of the shift fork, relative to the housing, axially translates the clutch ring between a disengaged position and an engaged position in which the internal teeth of the clutch ring are engaged with external teeth of the driven member to rotationally couple the clutch ring and the driven member; and

a first pin coupled to an arm of the shift fork;

a shift pad positioned between the shift fork and the clutch ring, the shift pad defining a recess configured to receive the first pin and allow pivotal movement between the shift fork and the shift pad; and

a position sensor enclosed by the housing and the housing cover, the position sensor arranged within the housing cover to detect a position of a second pin of the actuator.

12. The disconnect system of claim 11 , wherein, in the engaged position, the clutch ring axially overlaps a portion of the external teeth of the drive member and a portion of the external teeth of the driven member.

13. The disconnect system of claim 11 , wherein at least a portion of each of the clutch ring and the shift fork are arranged within the housing.

14. The disconnect system of claim 13 , further comprising a speed sensor arranged within the housing and arranged to detect a rotational speed of the clutch ring.

15. The disconnect system of claim 14 , wherein the clutch ring includes external teeth arranged around a circumference thereof, and wherein the speed sensor detects the external teeth of the clutch ring to determine a rotational speed of the clutch ring.

16. The disconnect system of claim 11 , wherein the clutch ring includes a tapered surface that defines a reduced axial width of the clutch ring as the clutch ring extends radially outward.

17. The disconnect system of claim 11 , further comprising a clevis coupled between the actuator and the shift fork, wherein the clevis includes a yoke recess to receive a portion of the shift fork.

18. The disconnect system of claim 11 , wherein the shift pad is fabricated from a plastic material and has an arcuate shape that is complementary to a curvature of the clutch ring, and

wherein the first pin is formed with the shift fork.

19. The disconnect system of claim 11 , further comprising an annular bumper ring arranged between the clutch ring and an end surface of the drive member, wherein the annular bumper ring is configured to prevent or inhibit overtravel of the clutch ring.

20. A disconnect system for selectively coupling or disconnecting a drive member and a driven member, the disconnect system comprising:

a housing defining an interior space;

a housing cover configured to couple to the housing;

a clutch ring disposed and movable within the interior space of the housing, the clutch ring defining a channel that extends circumferentially around the clutch ring;

an actuator arranged within the housing and configured to move an actuator pin to actuate the clutch ring;

a position sensor enclosed by the housing and the housing cover, the position sensor arranged within the housing cover to detect a position of the actuator pin of the actuator;

a shift fork pivotally coupled to the housing such that pivotal movement of the shift fork, relative to the housing, axially translates the clutch ring between a disengaged position and an engaged position, the shift fork including:

a body that is pivotally coupled to the actuator pin of the actuator,

a first arm and a second arm extending from the body, the first arm including a first pin coupled to a distal end of the first arm, the first pin extending radially toward the clutch ring, and the second arm including a second pin coupled to a distal end of the second arm, the second pin extending radially toward the clutch ring,

a first shift pad defining a first pin recess configured to receive the first pin and allow pivotal movement between the shift fork and the shift pad, the first shift pad being received in the channel of the clutch ring and the first shift pad having an arcuate shape that is complementary to a curvature of the clutch ring, and
