Patent Images
1. A hub assembly comprising:
- a hub having a base and a hub shaft extending substantially perpendicularly from the base, the hub shaft having an outer end opposite the base, wherein the hub shaft includes a threaded surface over a portion thereof and at least a first locking feature positioned between the threaded surface and the outer end of the hub shaft;
a spin-on nut having a threaded bore formed therethrough, wherein threads of the threaded bore of the spin-on nut are configured to engage threads of the threaded surface of the hub shaft with the first locking feature positioned between the spin-on nut and the outer end of the hub shaft when the spin-on nut is fully engaged with the hub shaft, the spin-on nut including an indentation extending around the periphery of the threaded bore and configured to receive an outer edge of the locking hub cap in the indentation; and
a locking hub cap configured to fit over the outer end of the shaft with an outer end portion of the locking hub cap extending beyond and exposed outwardly beyond the spin-on nut, the locking hub cap having at least a second locking feature configured to engage the first locking feature in a releasable manner, wherein the first and second locking features resist movement of the locking hub cap in a direction substantially parallel to the hub shaft when engaged.

7. A locking hub cap comprising:
-
a base having an inner and outer surface; a shaft extending substantially perpendicularly from the inner surface; at least a first locking feature positioned on the shaft and configured to align with at least a second locking feature positioned on a vehicle hub assembly, wherein the base is rotatable relative to the vehicle hub assembly to align the first locking feature with the second locking feature, and wherein alignment of the first and second locking features enables the locking hub cap to remain coupled to the vehicle hub assembly when pressure is applied in a direction substantially parallel to the shaft towards the inner surface; and wherein the shaft of the locking hub cap is configured to engage the vehicle hub assembly with a portion of the locking hub cap extending beyond and exposed through a spin-on nut engaged with the vehicle hub assembly with an outer surface of the locking hub cap positioned in a generally circular indentation in the spin-off nut. - View Dependent Claims (8, 9)

10. A hub assembly comprising:
-
a hub having a base and a hub shaft extending substantially perpendicularly from the base, wherein the hub shaft includes an external surface that is at least partially threaded and a first locking feature; a spin-on nut having a plurality of arms extending at an angle from a central nut portion, wherein the central nut-portion includes a threaded bore having threads that are configured to engage threads of the external surface, and wherein an exterior surface of the central nut portion includes a circular indentation centered around the threaded bore; a locking hub cap having at least a second locking feature configured to align with the first locking feature to engage the locking hub cap with the hub in a releasable manner, wherein the first and second locking features are configured to enable the locking hub cap to resist movement relative to the hub in a direction substantially parallel to the hub shaft and away from the hub, and wherein an interior edge of the locking hub cap fits within the circular indentation of the spin-on nut such that the locking hub cap encloses the end of the hub shaft and extends axially outward from the spin-off nut such that the end of the locking hub cap is exposed outwardly and axially beyond the spin-off nut. - View Dependent Claims (11)
