Ball bearing braking apparatus

1. A braking apparatus comprising:

a hub interface component having outer surface configured to engage an inner surface of a wheel hub and comprising a bearing groove within an inner portion of the hub interface component, the bearing groove configured to allow a ball bearing to move within the bearing groove between a first barrier at a first end of the bearing groove and a second barrier at a second end of the bearing groove;

a non-rotating component comprising a bearing wall, the hub interface component configured to rotate relative to the non-rotating component unless the braking apparatus is in a braking configuration and the ball bearing is in a braking position where the ball bearing is positioned between the bearing wall and either one of the first barrier or the second barrier;

a bearing release mechanism configured to release the ball bearing from a non-braking position and allow the ball bearing to travel to the bearing groove; and

electronics configured to actuate the release mechanism to release the ball bearing in response to detection of a wireless signal.

2. A braking apparatus in accordance with claim 1 , wherein the hub interface component is further configured to move relative to the wheel hub when the braking apparatus is in the braking configuration and a torque applied to the hub component exceeds a torque threshold.

3. A braking apparatus in accordance with claim 2 , wherein the hub interface component comprises a plurality of indentations within the outer surface of the hub interface component to engage at least one protrusion extending from an inner surface of the wheel hub to restrict rotation of the hub interface component relative to the wheel hub until the torque threshold is reached.

4. A braking apparatus in accordance with claim 1 , further comprising:

a bearing channel extending from the non-braking position to the bearing track, the bearing channel providing a path for the ball bearing to travel from the non-braking position to the bearing groove when the bearing groove is positioned next to an end of the bearing channel.

5. A braking apparatus in accordance with claim 4 , wherein the bearing release mechanism comprises:

a electric motor, a screw shaft, and a threaded block, wherein rotation of the electric motor rotates the screw shaft within the threaded block to move the threaded block between an extended position and a retracted position such that, when the threaded block is moved to the retracted position, the ball bearing is released from the non-braking position, travels down the bearing channel, and enters the bearing groove.

6. A braking apparatus in accordance with claim 5 , wherein the bearing groove is configured to move the ball bearing to the braking position when the wheel is rotated and the ball bearing is within the bearing groove.

7. A braking apparatus in accordance with claim 6 , wherein the bearing groove is configured to move the ball bearing to a forward braking position when the wheel is rotated forward and to a reverse braking position when the wheel is rotated in reverse, the forward braking position resulting when the ball bearing is interposed between a first bearing barrier of the bearing groove and a first bearing wall of the non-rotating component and the reverse braking position resulting when the ball bearing is interposed between a second bearing barrier of the bearing groove and a second bearing wall of the non-rotating component.

8. A braking apparatus in accordance with claim 7 , further comprising a bearing deflector configured to deflect the ball bearing over an opening of the bearing channel when the wheel is rotated forward and the ball bearing is moved past the opening, the bearing deflector further configured to all of the ball bearing to enter opening when the wheel is rotated in reverse and the ball bearing is moved from the forward braking position by the bearing groove.

9. A braking apparatus in accordance with claim 1 , wherein the bearing release mechanism comprises a mechanical actuator configured to push the ball bearing to position where rotation of the hub interface component moves the ball bearing to the braking position.

10. A braking apparatus in accordance with claim 1 , wherein the ball bearing is magnetic and the bearing release mechanism comprises a mechanical actuator that is magnetically attractive to the ball bearing and wherein the mechanical actuator is configured to move the ball bearing to the non-braking position using at least magnetic force.

11. A braking apparatus comprising:

a rotating component having a rotating component feature;

a non-rotating component having a non-rotating component feature;

a moveable interposer configured to inhibit rotation of the rotating component relative to the non-rotating component when the moveable interposer is in a braking position where the moveable interposer is positioned between the rotating component feature and the non-rotating component feature;

an interposer controller configured to move the moveable interposer to the braking position with movement at least partially caused by gravity and by rotation of the rotating component.

12. The braking apparatus of claim 11 , wherein the movement is caused by rotation of the rotating component after the moveable interposer is positioned in the rotating component feature.

13. The braking apparatus of claim 12 , wherein the movement is at least partially caused by mechanical actuator.

14. The braking apparatus of claim 13 , wherein the moveable interposer is a ball bearing.

15. The braking apparatus of claim 14 , wherein the rotating component feature is a bearing groove in the rotating component.

16. The braking apparatus of claim 15 , wherein the interposer controller is configured to move the moveable interposer in response to receipt of a wireless signal.

17. A braking apparatus comprising:

a rotating component having a rotating component feature;

a non-rotating component having a non-rotating component feature;

a moveable interposer configured to inhibit rotation of the rotating component relative to the non-rotating component when the moveable interposer is in a braking position where the moveable interposer is positioned between the rotating component feature and the non-rotating component feature and configured to not inhibit rotation of the rotating component relative to the non-rotating component when the moveable interposer is in a non-braking position where the moveable interposer is not positioned between the rotating component feature and the non-rotating component feature; and

an interposer controller configured to move the moveable interposer from the braking position and to the non-braking position where the movement is at least partially due to magnetic force.

18. The braking apparatus of claim 17 , wherein the moveable interposer is magnetic and is magnetically attracted to a mechanical actuator and wherein the mechanical actuator is retracted to pull the moveable interposer using the magnetic force to the non-braking position.

19. The braking apparatus of claim 18 , wherein the moveable interposer is ball bearing.

20. The braking apparatus of claim 19 , wherein the rotating component feature is a bearing groove in the rotating component.

21. The braking apparatus of claim 20 , wherein the interposer controller is configured to move the moveable interposer in response to receipt of a wireless signal.
