Wheel assemblies
View Patent ↗A wheel assembly includes a circular frame arranged about a hub of a hub assembly, and shock absorbers coupling the hub assembly to the circular frame for providing relative motion between the circular frame and the hub assembly. Each of the shock absorbers extends along a tangent line to a circle that is coaxial with respect to the circular frame and the hub for providing tangential shock absorption along each tangent line.
1. A wheel assembly, comprising:
a circular frame arranged about a hub of a hub assembly; and
shock absorbers, the shock absorbers are arranged in a crown that circumscribes the hub, the shock absorbers are pivotally connected end-to-end at corners of the crown alternately to the hub assembly and to the circular frame coupling the hub assembly to the circular frame for providing relative motion between the circular frame and the hub assembly, each of the shock absorbers extends along a tangent line to a circle that is coaxial with respect to the circular frame and the hub for providing tangential shock absorption along each said tangent line.
2. The wheel assembly according to claim 1 , wherein each of the shock absorbers is a piston-cylinder assembly.
3. The wheel assembly according to claim 1 , wherein the hub assembly includes spokes radiating from the hub toward the circular frame to outer ends positioned inwardly and spaced-apart from the circular frame, and wherein the shock absorbers are pivotally connected end-to-end at the corners of the crown alternately to the outer ends of the spokes of the hub assembly and to the circular frame.
4. A wheel assembly, comprising:
a circular frame arranged about a hub of a hub assembly; and
shock absorbers between the circular frame and the hub assembly, the shock absorbers are disposed circumferentially about the hub, the shock absorbers are pivotally connected end-to-end alternately to the hub assembly and to the circular frame, each of the shock absorbers extends along an axis that is tangential to a circle that is coaxial with respect to the circular frame and the hub for providing tangential shock absorption along each said axis.
5. The wheel assembly according to claim 4 , wherein each of the shock absorbers is a piston-cylinder assembly.
6. The wheel assembly according to claim 4 , wherein the hub assembly includes spokes radiating from the hub toward the circular frame to outer ends positioned inwardly and spaced-apart from the circular frame, and the shock absorbers are pivotally connected end-to-end alternately to the outer ends of the spokes and to the circular frame.
7. A wheel assembly, comprising:
a circular frame arranged about a hub of a hub assembly;
parallel sets of shock absorbers coupling the hub assembly to the circular frame for providing relative motion between the circular frame and the hub assembly; and
the shock absorbers of each of the parallel sets of shock absorbers are arranged in a crown that circumscribes the hub, and are pivotally connected end-to-end at corners of the crown alternately to the hub assembly and to the circular frame coupling the hub assembly to the circular frame for providing relative motion between the circular frame and the hub assembly; and
each of the shock absorbers extends along a tangent line to a circle that is coaxial with respect to the circular frame and the hub for providing tangential shock absorption along each said tangent line.
8. The wheel assembly according to claim 7 , wherein each of the shock absorbers is a piston-cylinder assembly.
9. The wheel assembly according to claim 8 , wherein the hub assembly includes spokes radiating from the hub toward the circular frame to outer ends positioned inwardly and spaced-apart from the circular frame, and wherein the shock absorbers are pivotally connected end-to-end at the corners of the crown alternately to the outer ends of the spokes of the hub assembly and to the circular frame.
10. A wheel assembly, comprising:
a circular frame arranged about a hub of a hub assembly; and
parallel sets of shock absorbers between the circular frame and the hub assembly, the shock absorbers of each one of the parallel sets of shock absorbers are disposed circumferentially about the hub, and are pivotally connected end-to-end alternately to the hub assembly and to the circular frame, each of the shock absorbers extends along an axis from the first end to the second end and that is tangential to a circle that is coaxial with respect to the circular frame and the hub for providing tangential shock absorption along each said axis.
11. The wheel assembly according to claim 10 , wherein each of the shock absorbers is a piston-cylinder assembly.
12. The wheel assembly according to claim 10 , wherein the hub assembly includes spokes radiating from the hub toward the circular frame to outer ends positioned inwardly and spaced-apart from the circular frame, and the shock absorbers are pivotally connected end-to-end alternately to the outer ends of the spokes and to the circular frame.
