Abstract

A secure locking hub system for locking a wheel hub of a vehicle to an axle is provided. The system has a locking ring that may be moved between locked and unlocked configurations. When locked, the hub is in a rotationally fixed position relative to the axle on which the hub is mounted. With the hub locked to the axle, the wheel will not rotate and the vehicle thus cannot be moved. The system additionally has a security lock that prevents any unauthorized individual from unlocking the wheel hub, thereby preventing theft of the vehicle.

Claims

1. A locking hub system comprising:

a hub coupled to an axle, wherein the axle has a splined section and has a threaded section having helical threads;

a threaded fastener having helical threads that are compatible with the threads on the axle;

a locking ring configured to mate with the splined section of the axle in a locked configuration and to decouple from the splined section of the axle in an unlocked configuration, wherein the hub is rotationally fixed relative to the axle in the locked configuration and free to rotate about the axle in the unlocked configuration;

an actuator operably connected to the locking ring and configured to move the locking ring in an axial direction between the locked configuration and the unlocked configuration; and

a lock configured to selectively limit operation of the actuator.

2. The locking hub system of claim 1, wherein the actuator is a mechanical actuator comprising a dial operably connected to the locking ring and configured to move the locking ring in an axial direction between the locked configuration and the unlocked configuration in response to rotational movement of the dial.

3. The locking hub system of claim 2, wherein the lock is configured to selectively limit rotational movement of the dial.

4. The locking hub system of claim 2, wherein the dial is secured to a housing that is fastened to the hub with bolts, wherein the dial is configured to cover a head of each bolt when the locking ring is in the locked configuration.

5. The locking hub system of claim 4, wherein each bolt has a tamper-proof head.

6. The locking hub system of claim 2, wherein the dial is operably connected to the locking ring by a cam that moves in an axial direction between the locked configuration and the unlocked configuration in response to rotational movement of the dial.

7. The locking hub system of claim 2, wherein the locking ring is biased in an inward axial direction by a compression spring disposed between the dial and the locking ring.

8. The locking hub system of claim 1, wherein the locking ring has an interior splined surface, and the splined section of the axle has an exterior splined surface positioned around a circumference of the axle and configured to mate with the interior splined surface of the locking ring.

9. The locking hub system of claim 1, wherein the axle is mounted in a rotationally fixed position.

10. A locking hub system comprising:

a hub coupled to an axle, wherein the axle has a splined section having an exterior splined surface positioned around a circumference of the axle and has a threaded section having helical threads;

a threaded fastener having helical threads that are compatible with the threads on the axle;

a locking ring having an interior splined surface configured to mate with the exterior splined surface of the axle in a locked configuration and to decouple from the exterior splined surface of the axle in an unlocked configuration, wherein the hub is rotationally fixed relative to the axle in the locked configuration and free to rotate about the axle in the unlocked configuration; and

a cap assembly comprising a keyed lock, a lock pawl, and a dial that is operably connected to the locking ring and configured to move the locking ring in an axial direction between the locked configuration and the unlocked configuration in response to rotational movement of the dial, and wherein the pawl is configured to lock the dial in a rotationally fixed position in response to input from a key configured to operate the lock.

11. The locking hub system of claim 10, wherein the cap assembly is secured to a housing that is fastened to the hub with bolts, wherein the dial is configured to cover a head of each bolt when the locking ring is in the locked configuration.

12. The locking hub system of claim 11, wherein each bolt has a tamper-proof head.

13. The locking hub system of claim 10, wherein the dial is operably connected to the locking ring by a cam that moves in an axial direction between the locked configuration and the unlocked configuration in response to rotational movement of the dial.

14. The locking hub system of claim 10, wherein the locking ring is biased in an inward axial direction by a compression spring disposed between the dial and the locking ring.

15. The locking hub system of claim 10, wherein the axle is mounted in a rotationally fixed position.

16. A conveyance vehicle having at least one wheel mounted on

a locking hub system comprising:

a hub coupled to an axle, wherein the axle has a splined section and has a threaded section having helical threads;

a threaded fastener having helical threads that are compatible with the threads on the axle;

a locking ring configured to mate with the splined section of the axle in a locked configuration and to decouple from the splined section of the axle in an unlocked configuration, wherein the hub is rotationally fixed relative to the axle in the locked configuration and free to rotate about the axle in the unlocked configuration;

an actuator operably connected to the locking ring and configured to move the locking ring in an axial direction between the locked configuration and the unlocked configuration; and

a lock configured to selectively limit operation of the actuator.

17. The conveyance vehicle of claim 16, wherein the actuator is a mechanical actuator comprising a dial operably connected to the locking ring and configured to move the locking ring in an axial direction between the locked configuration and the unlocked configuration in response to rotational movement of the dial.

18. The conveyance vehicle of claim 17, wherein the lock is configured to selectively limit rotational movement of the dial.

19. The conveyance vehicle of claim 17, wherein the dial is secured to a housing that is fastened to the hub with bolts, wherein the dial is configured to cover a head of each bolt when the locking ring is in the locked configuration.

20. The conveyance vehicle of claim 16, wherein the locking ring has an interior splined surface, and the splined section of the axle has an exterior splined surface positioned around a circumference of the axle and configured to mate with the interior splined surface of the locking ring.
