| 20110030861 | Internal wheel suspension and shock absorbing system - An internal wheel suspension and shock absorbing system, including a hub with radially extending rods or blades, cooperating with sector braces, fixedly mounted by hubs to the interior of the rim for a wheel. The rods and blades secure onto a hub, that mounts onto the vehicle axle, for rotation. When a force is encountered, the forces are absorbed by the blades that extend either through or cooperate with the braces and biasing springs, which are adjustable, that bias against the outer radial edges of the blades or telescoping rods, and absorb the vector forces generated from any impact. | 02-10-2011 |
| 20150090379 | WHEEL ASSEMBLIES - 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. | 04-02-2015 |
