Abstract
Abstract A vehicle wheel having rim and disc halves with the outer edges of the disc portions abutting each other and fixed together by a seam weld. The disc portions are axially spaced apart radially inwardly of the seam weld and the space between the disc portions is filled with an adhesive elastomeric material, such as a urethane foam. A bolt hole spacer ring is received between the disc portions and retained therein by the elastomeric material.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
176 words
A vehicle wheel adapted to receive a tubeless pneumatic tire thereon comprising: two metallic wheel halves each being in one piece and having a rim portion and an integral disc portion, each of said wheel halves having an annular edge with said edges disposed in the vicinity of the junction of the rim and disc portions in generally opposed abutting relation, means adjacent said edges fixing said wheel halves together with said rim portions disposed such that a tubeless pneumAtic tire may be received thereon, said disc portions each having a central portion, said central portions being disposed in spaced relation axially of the wheel, and a cured elastomeric material adherently secured to both of said disc portions and extending generally circumferentially to fill at least a portion of the space between the inner faces of said disc portions to provide a seal radially inwardly of said edges preventing the escape of air from the interior of a tubeless pneumatic tire received on said rim portions to the atmosphere via said space between the disc portions.
Claim 2
Dependent Claim
176 words
A vehicle wheel adapted to receive a tubeless pneumatic tire thereon comprising: two metallic wheel halves each being in one piece and having a rim portion and an integral disc portion, each of said wheel halves having an annular edge with said edges disposed in the vicinity of the junction of the rim and disc portions in generally opposed abutting relation, means adjacent said edges fixing said wheel halves together with said rim portions disposed such that a tubeless pneumAtic tire may be received thereon, said disc portions each having a central portion, said central portions being disposed in spaced relation axially of the wheel, and a cured elastomeric material adherently secured to both of said disc portions and extending generally circumferentially to fill at least a portion of the space between the inner faces of said disc portions to provide a seal radially inwardly of said edges preventing the escape of air from the interior of a tubeless pneumatic tire received on said rim portions to the atmosphere via said space between the disc portions.
Claim 3
Dependent Claim
32 words
The vehicle wheel of claim 1 wherein said means comprises a seam weld extending adjacent said edges, and said elastomeric material extends circumferentially continuously between said disc portions adjacent said seam weld.
Claim 4
Dependent Claim
63 words
The vehicle wheel of claim 2 having a plurality of circumferentially spaced mounting holes extending generally axially of the wheel through both of said disc portions, rigid spacer means extending generally axially between and bearing on said disc portions and surrounding said mounting holes, said elastomeric material engaging and retaining said spacer means between said disc portions in alignment with said mounting holes.
Claim 5
Dependent Claim
45 words
The vehicle wheel of claim 2 having a plurality of circumferentially spaced vent holes extending generally axially of the wheel through both of said disc portions and through said elastomeric material such that the elastomeric material adjacent the periphery of said vent holes is exposed.
Claim 6
Dependent Claim
63 words
The vehicle wheel of claim 4 having a plurality of circumferentially spaced mounting holes extending generally axially of the wheel through both of said disc portions, rigid spacer means extending generally axially between and bearing on said disc portions and surrounding said mounting holes, said elastomeric material engaging and retaining said spacer means between said disc portions in alignment with said mounting holes.
Claim 7
Dependent Claim
45 words
The vehicle wheel of claim 1 having a plurality of circumferentially spaced vent holes extending generally axially of the wheel through both of said disc portions and through said elastomeric material such that the elastomeric material adjacent the periphery of said vent holes is exposed.
Claim 8
Dependent Claim
37 words
The vehicle wheel of claim 6 wherein at least a portion of the elastomeric material adjacent the generally radial outer periphery of said vent holes is exposed to view from the outboard face of said vehicle wheel.
Claim 9
Dependent Claim
66 words
The vehicle wheel of claim 1 having a plurality of circumferentially spaced mounting holes extending generally axially of the wheel through both of said disc portions, rigid spacer means extending generally axially of the wheel between and bearing on said disc portions and surrounding said mounting holes, said elastomeric material engaging and retaining said spacer means between said disc portions in alignment with said mounting holes.
Claim 10
Dependent Claim
43 words
The vehicle wheel of claim 8 wherein said rigid spacer means comprises a metallic ring having generally opposed faces bearing on said disc portions adjacent said mounting holes and having holes extending generally axially therethrough in generally coaxial alignment with said mounting holes.
Claim 11
Dependent Claim
54 words
The vehicle wheel of claim 9 wherein said metallic ring has a plurality of circumferentially spaced holes extending generally radially therethrough and said cured elastomeric material extends into said last-mentioned holes in said metallic ring to at least in part retain said metallic ring between said disc portions in alignment with said mounting holes.
Claim 12
Dependent Claim
45 words
The vehicle wheel of claim 1 wherein each of said metallic wheel halves is made of magnesium, and said elastomeric material engages at least most of the inner surface of each of said disc portions to seal such inner surface from attack by corrosive substances.
