    摘要： A wheel and tire assembly for toy vehicles wherein a generally cylindrical wheel of rigid material has a reduced portion projecting concentrically from the outer side thereof and a peripheral groove adjacent the inner side thereof and a tire of resilient material encircling the wheel and having an outer side wall tightly encircling the reduced portion and an annular bead on the inner side of the tire seated in said peripheral groove to prohibit outward axial removal of the tire from the wheel.

    摘要： A magnetic wheel having axial end faces oppositely polarized magnetically, is maintained thereby in rolling contact with a magnetic flux conducting path. The wheel when driven propels a vehicle frame along the path without reliance on traction. Rolling contact is maintained by the magnetic field established by the flux extending between the end faces through the surface of the path producing contact holding forces acting on the nonpolarized rim of the wheel.
