Abstract

A secure locking hub system for locking a wheel hub of a trailer to a fixed axle of the trailer is provided. The system has a locking ring that may be moved between a locked and unlocked configuration. 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 a fixed axle, the trailer cannot be moved when locked. The system additionally has a security lock that secures the locking ring in place in order to prevent any unauthorized individual from unlocking the hub and stealing the trailer.

Claims

1. ) A locking hub system comprising:

a hub rotatably coupled to and positioned around a fixed axle, wherein the hub has a hub interior splined surface;

an axle exterior splined surface positioned around a circumference of the fixed axle;

a locking ring having a locking ring exterior splined surface configured to mate with the hub interior splined surface, wherein the locking ring has a locking ring interior splined surface configured to mate with the axle exterior splined surface in a locked configuration and to decouple from the axle exterior splined surface in an unlocked configuration; and

a lock configured to selectively limit movement of the locking ring between the locked and unlocked configurations.

2. ) The locking hub system of claim 1, wherein the lock is configured to move the locking ring in an axial direction into the locked configuration and into the unlocked configuration in response to input from a key configured to operate the lock.

3. ) The locking hub system of claim 2, wherein the lock is secured to a cap that is fastened to the hub with tamper-proof fasteners.

4. ) The locking hub system of claim 3, wherein the lock comprises a lever that rotates in response to input from the key, wherein the lever is fixedly attached to a rotating cam configured to move the locking ring in an axial direction into the locked configuration and into the unlocked configuration.

5. ) The locking hub system of claim 4, wherein the locking ring is biased in an inward axial direction by a compression spring disposed between the cap and the locking ring.

6. ) The locking hub system of claim 2, wherein the lock comprises a lever that rotates in response to input from the key, wherein the lever is fixedly attached to a rotating cam configured to move the locking ring in an axial direction into the locked configuration and into the unlocked configuration.

7. ) The locking hub system of claim 1, wherein the axle exterior splined surface is disposed on an axle ring removably secured directly to and positioned around the fixed axle in a rotationally fixed position, and wherein the hub comprises a bearing positioned around and in contact with an external cylindrical surface of the axle ring.

8. ) The locking hub system of claim 1, wherein the hub will not rotate when the locking ring is in the locked configuration, and wherein the hub will freely rotate when the locking ring is in the unlocked configuration.

9. ) A locking hub system comprising:

a hub positioned around a fixed axle and rotatably coupled to the fixed axle via a bearing, wherein the hub has a hub interior splined surface;

an axle ring removably secured directly to and positioned around the fixed axle in a rotationally fixed position, wherein the axle ring has an axle exterior splined surface positioned around a circumference of the fixed axle, wherein the bearing is positioned around and in contact with an external cylindrical surface of the axle ring; and

a cap assembly comprising a keyed lock secured to a cap, wherein the lock comprises a lever that rotates in response to input from a key configured to operate the lock, wherein the lever is fixedly attached to a rotating cam configured to move a locking ring in an axial direction into a locked configuration and into an unlocked configuration, wherein the locking ring has a locking ring exterior splined surface configured to mate with the hub interior splined surface, and wherein the locking ring has a locking ring interior splined surface configured to mate with the axle exterior splined surface in the locked configuration and to decouple from the axle exterior splined surface in the unlocked configuration.

10. ) The locking hub system of claim 9, wherein the hub will not rotate when the locking ring is in the locked configuration, and wherein the hub will freely rotate when the locking ring is in the unlocked configuration.

11. ) The locking hub system of claim 9, wherein the cap assembly is fastened to the hub with tamper-proof fasteners.

12. ) The locking hub system of claim 9, wherein the locking ring is biased in an inward axial direction by a compression spring disposed between the cap and the locking ring.

13. ) A trailer having opposing wheels, wherein at least one wheel is mounted on a locking hub system comprising:

a hub rotatably coupled to and positioned around a fixed axle, wherein the hub has a hub interior splined surface;

an axle exterior splined surface positioned around a circumference of the fixed axle;

a locking ring having a locking ring exterior splined surface configured to mate with the hub interior splined surface, wherein the locking ring has a locking ring interior splined surface configured to mate with the axle exterior splined surface in a locked configuration and to decouple from the axle exterior splined surface in an unlocked configuration; and

a keyed lock configured to selectively limit movement of the locking ring between the locked and unlocked configurations.

14. ) The trailer of claim 13, wherein the lock is configured to move the locking ring in an axial direction into the locked configuration and into the unlocked configuration in response to input from a key configured to operate the lock.

15. ) The trailer of claim 14, wherein the lock is secured to a cap that is fastened to the hub with tamper-proof fasteners.

16. ) The trailer of claim 15, wherein the lock comprises a lever that rotates in response to input from the key, wherein the lever is fixedly attached to a rotating cam configured to move the locking ring in an axial direction into the locked configuration and into the unlocked configuration.

17. ) The trailer of claim 16, wherein the locking ring is biased in an inward axial direction by a compression spring disposed between the cap and the locking ring.

18. ) The trailer of claim 14, wherein the lock comprises a lever that rotates in response to input from the key, wherein the lever is fixedly attached to a rotating cam configured to move the locking ring in an axial direction into the locked configuration and into the unlocked configuration.

19. ) The trailer of claim 13, wherein the axle exterior splined surface is disposed on an axle ring secured directly to and positioned around the fixed axle, and wherein the hub comprises a bearing positioned around and in contact with an external cylindrical surface of the axle ring.

20. ) The trailer of claim 13, wherein the hub will not rotate when the locking ring is in the locked configuration, and wherein the hub will freely rotate when the locking ring is in the unlocked configuration.
