Abstract:
A spiral spring wheel includes a ring spring and a leaf spring assembly surrounding an outer surface of the ring spring. A shoe is placed over the leaf spring assembly. The shoe sidewalls extend past the leaf spring assembly and tuck under the ring spring. Each torsion spring in a first plurality of torsion springs extends in a clockwise spiral shape from a flange to an inner surface of the ring spring. Each torsion spring in a second plurality of torsion springs extends in a counterclockwise spiral shape from the flange to the inner surface of the ring spring.
