FIELD: transport.
SUBSTANCE: invention relates to physics of magnetism and may be used as wheel on magnetic cushion instead of wheel rolling bearing when bearing lubrication is inexpedient or impossible. Wheel comprises round rim with elastic tread fitted on its outer surface and fixed axle about which said rim revolves. Additionally, wheel incorporates round rim arranged coaxially inside said round rim with elastic tread and mechanically engaged with said fixed axle by crossarms or spokes. Both round rims are made from magnetically hard and magnetised ferromagnetic. Magnetic similar poles of said round rims face each other. Inner concave surface of said rim with elastic tread and outer convex surface of additional rim revolve about fixed axle with relevant radii of said rim curved lines, i.e. parabolas, circle arcs or combinations thereof. Width of round rim with elastic tread exceeds that of additional round rim.
EFFECT: stable magnetic suspension along in three coordinates, plus simultaneous spring-loading.
