Vehicle with variable speed transmission

Abstract From the Canadian patent

A vehicle adapted to move along a supporting surface comprising a frame, a wheel having a centrally located huh mounted on the frame for rotational movement about a first rotational axis relative to the frame and, an inner rotatable member at least partially within the hub. The inner rotatable member is mounted for rotational movement about a second rotational axis. The inner rotatable member and the hub are movable relative to each other along a path having a radial component to permit adjustment in the relative radial position of the first and second rotational axes. The hub and the inner rotatable member are drivingly interconnected by a mechanism which includes a one-way clutch. The …
