Abstract
An aircraft wheel assembly that includes first and second hub components having an axis and respective first and second sets of circumferentially spaced apart interface elements. The first and second hub components may be rotatable relative to one another about the axis between a first position and a second position. In the first position, the first set of interface elements is axially movable relative to the second set of interface elements. In the second position the first set of interface elements axially overlaps the second set of interface elements to prevent axial movement of the first hub component relative to the second hub component.
Claims27
An aircraft wheel assembly comprising:
- first and second hub components having an axis and respective first and second wheel sections and respective first and second sets of circumferentially spaced apart interface elements protruding radially from the respective first and second wheel sections;
- wherein the first and second hub components are rotatable relative to one another about the axis between a first position in which the first set of interface elements is axially movable relative to the second set of interface elements and a second position in which the first set of interface elements axially overlaps the second set of interface elements to axially lock the first hub component relative to the second hub component to prevent relative axial movement between the first and second hub components,
- wherein in the axially locked second position, first interfaces of the respective first set of radially protruding interface elements are in axially abutting engagement with second interfaces of the respective second set of radially protruding interface elements such that the first and second hub components react structural tire loads and pressure through the engagement of the first and second sets of radially protruding interface elements,
- wherein said abutting engagement is between an axially outer surface of the respective first set of interface elements and an axially inner surface of the respective second set of interface elements, and
- wherein the abutting engagement occurs at respective ends opposite of respective rim flanges of the first and second wheel sections further comprising a lock that is configured to prevent rotational movement of the first hub component relative to the second hub component when the first and second hub components are in the second position wherein said lock is disposed radially inward of the abutting engagement.

An aircraft wheel assembly comprising:
- first and second wheel components having an axis and respective first and second wheel sections and respective circumferentially disposed tongue and groove engaging portions that protrude radially from the respective first and second wheel sections;
- wherein the tongue and groove engaging portions are interconnectable to form circumferentially disposed tongue and groove joints that axially lock the first and second wheel components to prevent relative axial movement between the first and second wheel components,
- wherein in the axially locked position, first interfaces of the respective radially protruding tongue engaging portions are in axially abutting engagement with second interfaces of the respective radially protruding groove engaging portions such that the first and second wheel components react tire loads and pressure through the engagement of the respective radically protruding tongue engaging portions and groove engaging portions,
- wherein said abutting engagement is between an axially outer surface of the respective tongue engaging portions and an axially inner surface of the respective groove engaging portions, and
- wherein the abutting engagement occurs at respective ends opposite of respective rim flanges of the first and second wheel sections, further comprising a lock that is configured to prevent rotational movement of the first wheel component relative to the second wheel component when the first and second wheel components are in the axially locked position wherein said lock is disposed radially inward of the abutting engagement.

A method of assembling an aircraft wheel comprising:
- providing first and second hub components having an axis and respective first and second wheel sections and respective first and second sets of circumferentially spaced apart interface elements protruding radially from the respective first and second wheel sections
- moving the first set of circumferentially spaced apart radially protruding interface elements of the first hub component axially relative to the second set of circumferentially spaced apart radially protruding interface elements of the second hub component,
- wherein the first hub component is an inboard primary wheel component having a first annular rim flange and the second hub component is an outboard primary wheel component having a second annular rim flange, which first and second annular rim flanges are configured to support respective beads of a tire thereon such that when the tire is inflated the beads of the tire exert an outward force on the respective first and second rim flanges, or the first hub component is an outboard primary wheel component having a first annular rim flange and the second hub component is an inboard primary wheel component having a second annular rim flange, which first and second annular rim flanges are configured to support respective beads of a tire thereon such that when the tire is inflated the beads of the tire exert an outward force on the respective first and second rim flanges;
- and
- rotating the first hub component relative to the second hub component until the first set of radially protruding interface elements axially overlaps the second set of radially protruding interface elements to axially lock the first hub component relative to the second hub component to prevent relative axial movement between the first and second hub components,
- wherein in the axially locked position, first interfaces of the respective first set of radially protruding interface elements are in axially abutting engagement with second interfaces of the respective second set of radially protruding interface elements such that the first and second hub components react structural tire loads and pressure through the engagement of the first and second sets of radially protruding interface elements,
- wherein said abutting engagement is between an axially outer surface of the respective first set of interface elements and an axially inner surface of the respective second set of interface elements, and
- wherein the abutting engagement occurs at respective ends opposite of said respective first and second rim flanges of the first and second wheel sections, further comprising a lock that is configured to prevent rotational movement of the first hub component relative to the second hub component when the first and second hub components are in the axially locked position wherein said lock is disposed radially inward of the abutting engagement.
