Wheel mounting sleeve
View Patent ↗A sleeve for a fastener aperture in a vehicle wheel includes a tubular body having a first end and a plurality of external conically shaped barbs. The barbs include successively increasing outer diameters as a distance from the first end increases. A head radially outwardly extends from a second end of the body and is adapted to engage a land on the wheel that encompasses the fastener aperture. A bore extends through the body and the head and is adapted to receive a wheel fastener.
1. A sleeve for a fastener aperture in a vehicle wheel, the sleeve comprising:
a tubular body having a first end and a plurality of external conically shaped barbs, the barbs having successively increasing outer diameters as a distance from the first end increases;
a head radially outwardly extending from a second end of the body and adapted to engage a land on the wheel that encompasses the fastener aperture; and
a bore extending through the body and the head being adapted to receive a wheel fastener, wherein the barbs include a material having a yield strength greater than a yield strength of the vehicle wheel, the body being shaped to mechanically deform a portion of the wheel and retain the deformed portion between adjacent barbs.
2. The sleeve of claim 1 wherein at least one of the barbs is adapted to engage a side wall of the wheel fastener aperture in an interference fit.
3. The sleeve of claim 1 wherein a portion of the bore within the head includes a conical shape.
4. The sleeve of claim 1 wherein the body includes five conically shaped external surfaces.
5. The sleeve of claim 4 wherein a maximum diameter end of one of the conical surfaces is adjacent to a minimum diameter end of another one of the conical surfaces.
6. The sleeve of claim 5 further including a radially extending back face interconnecting the one and the another one of the conical surfaces.
7. The sleeve of claim 1 wherein the head and the body are portions of a one-piece monolithic sleeve.
8. The sleeve of claim 7 , wherein the sleeve includes a heat treated steel.
9. The sleeve of claim 1 wherein the head includes an external cylindrical surface adapted to be spaced apart from the wheel.
10. A wheel and sleeve assembly comprising:
a metal vehicle wheel including a mounting flange having a plurality of apertures adapted to receive wheel mounting fasteners, wherein each aperture includes a conically shaped wall; and
a sleeve positioned within each fastener aperture with an interference fit with the conically shaped wall, each sleeve including:
a tubular body having a plurality of barbs, each barb having a different maximum diameter such that the maximum diameters of the barbs define a tapered profile of the body substantially matching a profile of the conically shaped wall and
a flange radially outwardly extending from an end of the body, wherein the flange is adapted to engage a portion of the wheel that encompasses the fastener aperture.
11. The assembly of claim 10 wherein at least one barb includes a conical surface terminating at a substantially radially extending back face.
12. The assembly of claim 10 wherein each of the barbs includes a conical surface.
13. The assembly of claim 12 wherein a maximum diameter end of one of the conical surfaces is adjacent to a minimum diameter end of another one of the conical surfaces.
14. The assembly of claim 13 further including a radially extending back face interconnecting the one and the another one of the conical surfaces.
15. The assembly of claim 10 wherein the sleeve includes a conical inner wall.
16. The assembly of claim 15 wherein the wheel includes a counterbore coaxially aligned with the conically shaped wall, the counterbore having a substantially planar land circumscribed by a cylindrical wall, the flange engaging the land.
17. The assembly of claim 10 wherein the conical wall of the wheel includes a non-ferrous material and the sleeve barbs include a ferrous material.
18. A wheel and sleeve assembly comprising:
a metal vehicle wheel including a mounting flange having a plurality of apertures adapted to receive wheel mounting fasteners, wherein each aperture includes a conically shaped wall; and
a sleeve positioned within each fastener aperture with an interference fit, each sleeve including:
a tubular body having a plurality of barbs, each barb having a different maximum diameter such that the maximum diameters of the barbs define a tapered profile of the body substantially matching a profile of the conically shaped wall and
a flange radially outwardly extending from an end of the body, wherein the flange is adapted to engage a portion of the wheel that encompasses the fastener aperture, wherein the wheel includes a counterbore coaxially aligned with the conically shaped wall, the counterbore having a substantially planar land circumscribed by and directly adjoining a cylindrical wall, the flange engaging the land, wherein the flange includes an outer periphery spaced apart from the cylindrical wall.
19. A wheel and sleeve assembly comprising:
a metal vehicle wheel including a mounting flange having a plurality of apertures adapted to receive wheel mounting fasteners, wherein each aperture includes a conically shaped wall; and
a sleeve positioned within each fastener aperture with an interference fit, each sleeve including:
a tubular body having a plurality of barbs, each barb having a different maximum diameter such that the maximum diameters of the barbs define a tapered profile of the body substantially matching a profile of the conically shaped wall and
a flange radially outwardly extending from an end of the body, wherein the flange is adapted to engage a portion of the wheel that encompasses the fastener aperture, wherein the conical wall of the wheel includes a non-ferrous material and the sleeve barbs include a ferrous material, wherein the non-ferrous material deforms during insertion of the sleeve within the wheel aperture and becomes trapped by the barbs to restrict movement of the sleeve in a direction opposite the insertion direction.
