ABSTRACT:
A dynamic steerable spring for axially mounting for supporting a compressive load as it would experience as a vehicle wheel, the load from such vehicle being distributed being evenly transferred to a spring hub, as a replacement for a conventional pneumatic or non pneumatic tire. The spring is preferably manufactured from a single flat sheet of a spring steel type material that is formed into a circular disk that is cut by identical equally spaced radial slots from the disk circumference to a radial distance from the disk center, that is the spring hub wherethrough radially spaced lug bolt holes are formed, with the disk elements between the slots being identical and each terminating in essentially a rectangular end portion. The flat disk is fitted between opposing male and female dies, or the like, that are moved together to bend the disk into the spring where the elements, spaced at equal distances from the hub and bent outwardly from the hub plane, and are then curved to where the finger portions extend across the hub plane. A pair of springs can be joined at the hubs, with the lug holes aligning and the finger end portions interdigitating to form a dual steerable spring. The single or dual spring can receive one or more non-elastic hoops fitted over and under the fingers, and the spring fingers can receive an elastomeric cap formed therearound, and an elastomeric side can be formed around the elements above the hub to form the wheel.
