Automotive wheel with spoke assemblies on opposing sides
A wheel assembly for an automotive vehicle is described herein. The assembly includes a cylindrical rim, a tire around the rim, two spoke assemblies, a wheel hub, a brake assembly, and a mounting arm. The rim is symmetrical, and has a first flange on a first side of the rim and a second flange on a second side of the rim. The tire is disposed around the rim. The first spoke assembly is coupled to the first flange and has a hub-mounting structure at its center. The second spoke assembly is coupled to the second flange and has an opening at its center. The wheel hub and brake assembly are disposed inside the rim between the first and second spoke assemblies, coupled to the hub-mounting structure. The mounting arm passes through the opening at the center of the second spoke assembly and couples the wheel assembly to the vehicle.
1. A wheel assembly for a motorized passenger or cargo vehicle, the wheel assembly comprising:
a cylindrical symmetrical rim having a first flange on a first side of the rim and a second flange on a second side of the rim, each flange encircling the rim;
a tire around the rim between the flanges;
a first spoke assembly coupled to the first flange and having a hub-mounting structure at the center of the first spoke assembly;
a second spoke assembly coupled to the second flange and having an opening at the center of the second spoke assembly;
a wheel hub between the first and second spoke assemblies, and coupled to the hub-mounting structure;
a brake assembly coupled to one or more of the wheel hub or the hub-mounting structure;
a mounting arm coupled to one or more of the hub-mounting structure, the wheel hub, or the brake assembly, and passing through the opening, the mounting arm pivotably coupled to a vehicle frame member, coupling the wheel assembly to the motorized passenger or cargo vehicle.
2. The vehicle wheel assembly of claim 1 , the second spoke assembly further comprising a hub-mounting structure in the opening fixedly or rotatably coupling the second spoke assembly to the wheel hub, the brake assembly, or both.
3. The vehicle wheel assembly of claim 1 , the second spoke assembly further comprising a support structure in the opening fixedly coupled to the arm and rotatably coupled to the second spoke assembly.
4. The vehicle wheel assembly of claim 3 , wherein the support structure is integrated with the arm such that the support structure and the arm are monolithic.
5. The vehicle wheel assembly of claim 1 , wherein the brake assembly is a disc brake assembly.
6. The vehicle wheel assembly of claim 5 , wherein a brake pad of the disc brake assembly is fixedly coupled to the mounting arm, and wherein a disc of the disc brake assembly is rotatably coupled to the mounting arm.
7. The vehicle wheel assembly of claim 1 , wherein the brake assembly is a drum brake assembly.
8. The vehicle wheel assembly of claim 7 , wherein the drum brake assembly comprises one or more brake pads forced against an interior wall of the rim.
9. The vehicle wheel assembly of claim 1 , wherein the hub-mounting structure comprises a cylindrical plate having one or more openings through which one or more threaded bolts on the wheel hub pass, the wheel hub secured to the cylindrical plate by one or more nuts, each corresponding to one of the threaded bolts.
10. The vehicle wheel assembly of claim 1 , wherein either (a) the first and second spoke assemblies are fixedly coupled to the rim, (b) the first spoke assembly is fixedly coupled to the rim and the second spoke assembly is removably coupled to the rim, (c) the first spoke assembly is removably coupled to the rim and the second spoke assembly is fixedly coupled to the rim, or (d) the first and second spoke assemblies are removably coupled to the rim.
11. The vehicle wheel assembly of claim of claim 10 , wherein the first spoke assembly is removably coupled to the rim and the second spoke assembly is fixedly coupled to the rim, and wherein the second spoke assembly is rotatably coupled to the arm such that the arm provides support for the rim.
12. The vehicle wheel assembly of claim 10 , wherein the first and second spoke assemblies are fixedly coupled to the rim, wherein the second spoke assembly is rotatably coupled to the arm, and wherein the hub-mounting structure is removably coupled to the first spoke assembly.
13. The vehicle wheel assembly of claim 12 , wherein the removable hub-mounting structure comprises slideable rods corresponding to bored spokes of the first spoke assembly, wherein the rods extend outwards radially from the hub-mounting structure into the spokes.
14. The vehicle wheel assembly of claim 12 , wherein the removable hub-mounting structure comprises hub spokes and clamps around an outside end of each hub spoke, wherein the first spoke assembly comprises outer spokes corresponding to each hub spoke, and wherein the clamps clamp the hub spokes to the outer spokes.
15. The vehicle wheel assembly of claim 1 , wherein the first spoke assembly, the second spoke assembly, or both, comprise a first set of spokes fixedly coupled to the rim and a second set of spokes removably coupled to the rim.
16. The vehicle wheel assembly of claim 15 , wherein the first and second sets of spokes each comprise half the total number of spokes of the first or second spoke assembly.
17. The vehicle wheel assembly of claim 1 , wherein the first spoke assembly, the second spoke assembly, or both, comprise first and second sets of spokes, each set removably coupled to the rim.
18. The vehicle wheel assembly of claim 17 , wherein the first and second sets of spokes each comprise half the total number of spokes of the first or second spoke assembly.
19. The vehicle wheel assembly of claim 1 , wherein the second spoke assembly is rotatably coupled to the rim such that the second spoke assembly rotates freely with respect to the rim and the arm.
