wherein the sleeve includes a radially extending bolting lug and the first and second wheel-mounting flanges each include an inner edge defining a cavity large enough to receive the bolting lug.
2. The wheel hub of claim 1 , wherein the sleeve bolting flange includes a set of bolt holes aligned with the first set of mounting holes.
3. The wheel hub of claim 2 , wherein the wheel-mounting flange extends radially beyond the sleeve bolting flange.
4. The wheel hub of claim 1 , wherein the wheel-mounting flange extends radially beyond the sleeve bolting flange.
5. The wheel hub of claim 1 , wherein a brake component is positioned in part between the sleeve bolting flange and the wheel-mounting flange when the wheel mounting flange and the brake component are mounted to the sleeve bolting flange.
6. The wheel hub of claim 1 , wherein each of the inner edges of the first and second wheel-mounting flanges include a plurality of cavities, each cavity being large enough to receive the bolting lug and pass over the bolting lug in a plurality of particular rotational positions.
7. The wheel hub of claim 6 , wherein the bolting lug is one of a plurality of bolting lugs extending outwardly from the outer surface of the sleeve, the plurality of cavities of the first and second wheel-mounting flanges being large enough to receive the plurality of bolting lugs and pass over the plurality of bolting lugs at a plurality of particular rotational positions.
8. A wheel-mounting assembly for a vehicle having an axle and a wheel, the assembly comprising:
a sleeve rotatably mounted on the axle and having an outer surface, the sleeve including a sleeve bolting flange radially extending from the outer surface and a plurality of bolting lugs extending outwardly from the outer surface;
a wheel-mounting flange substantially surrounding the sleeve and removable from the sleeve, the wheel-mounting flange including an inner edge defining a plurality of flange cavities configured to receive the plurality of bolting lugs and pass over the plurality of bolting lugs at a plurality of particular rotational positions; and
a brake component positioned in part between the sleeve bolting flange and the wheel-mounting flange, the brake component including an inner edge defining a plurality of brake cavities configured to receive the plurality of bolting lugs and pass over the plurality of bolting lugs at a plurality of particular rotational positions.
9. The wheel mounting assembly of claim 8 , wherein the wheel-mounting flange has a first set of mounting holes for bolting the wheel-mounting flange to the sleeve bolting flange and a second set of mounting holes for bolting the wheel to the wheel-mounting flange, the second set of mounting holes being radially more distant from the sleeve than the first set of mounting holes.
10. The wheel-mounting assembly of claim 9 , wherein the brake component includes a set of bolting holes. substantially aligned with the first set of mounting holes, and wherein the sleeve bolting flange includes a set of bolt holes aligned with the first set of mounting holes of the wheel-mounting flange and the set of bolting holes of the brake component.
11. The wheel-mounting assembly of claim 10 , wherein the second set of mounting holes of the wheel-mounting flange define a first diameter and the brake component defines a second diameter that is less than the first diameter.
12. The wheel-mounting assembly of claim 9 , wherein the second set of mounting holes of the wheel-mounting flange define a first diameter and the brake component defines a second diameter that is less than the first diameter.
13. The wheel hub of claim 8 , wherein the entire inner edge of the wheel-mounting flange is inboard of the plurality of bolting lugs.
14. The wheel hub of claim 8 , wherein the entire inner edges of the wheel-mounting flange and the brake component are inboard of the plurality of bolting lugs.
15. A wheel hub comprising:
a sleeve mounted on an axle, the sleeve including an outer surface and a projection extending outwardly from the outer surface, the projection including an outboard-most surface; and
a wheel-mounting flange substantial surrounding the sleeve and including an inner edge with a cavity large enough to receive the projection, pass over the projection, and completely pass by the outboard-most surface of the protection in a particular rotational position;
wherein the inner edge of the wheel-mounting flange includes a plurality of cavities, each cavity being large enough to receive the projection, pass over the projection, and completely pass by the outboard-most surface of the projection in a plurality of particular rotational positions;
wherein the protection is one of a plurality of projections extending outwardly from the outer surface of the sleeve, each of the plurality of projections having an outboard-most surface, the plurality of cavities being large enough to receive the plurality of projections, pass over the plurality of projections, and completely pass by the outboard-most surfaces of the plurality of projections at a plurality of particular rotational positions; and
wherein the sleeve includes a sleeve bolting flange radially extending from the outer surface of the sleeve, and wherein the wheel-mounting flange includes a first set of mounting holes for bolting the wheel-mounting flange to the sleeve bolting flange and a second set of mounting holes for bolting a wheel to the wheel-mounting flange, the second set of mounting holes being radially more distant from the sleeve than the first set of mounting holes.
