Abstract
Abstract A magnetic wheel for supporting a vehicle employs a permanent magnet or an electromagnet in the shape of a ring which is journalled for rotation about a shaft. The shaft is loosely coupled to the frame of the vehicle for vertical movement by means of a member which positions a permanent magnet or an electromagnet within the ring which is poled to repel the ring. The wheel is adapted for steering by providing that the loose coupling includes a pivotal coupling and by providing a lever arm for connection to a steering mechanism, such as a rack and pinion mechanism.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
176 words
A magnetic wheel comprising: an electromagnetic ring having an inner surface and an outer surface and magnetized in a direction extending from one of said surfaces to the other; a disc connected to one edge of said ring and including an aperture which is concentric with the axis of said ring; a bearing carried on said disc and a shaft having one end thereof extending through said aperture and mounted in said bearing for rotation of said disc and ring thereabout and another end disposed within said ring; a magnet and means for connection to a vehicle frame mounting said magnet within said ring below said shaft and adjacent said inner surface, said magnet having a magnetic polarity such that a repelling force is provided between said magnet and said ring, said mounting means including an arm extending below said shaft and having a bore therein; and a pin depending from said shaft and extending through said bore for permitting free movement between said magnet and said ring in response to loading changes of the vehicle.
Claim 2
Dependent Claim
176 words
A magnetic wheel comprising: an electromagnetic ring having an inner surface and an outer surface and magnetized in a direction extending from one of said surfaces to the other; a disc connected to one edge of said ring and including an aperture which is concentric with the axis of said ring; a bearing carried on said disc and a shaft having one end thereof extending through said aperture and mounted in said bearing for rotation of said disc and ring thereabout and another end disposed within said ring; a magnet and means for connection to a vehicle frame mounting said magnet within said ring below said shaft and adjacent said inner surface, said magnet having a magnetic polarity such that a repelling force is provided between said magnet and said ring, said mounting means including an arm extending below said shaft and having a bore therein; and a pin depending from said shaft and extending through said bore for permitting free movement between said magnet and said ring in response to loading changes of the vehicle.
Claim 3
Dependent Claim
224 words
An antifriction magnetic wheel comprising: annular magnetic means including a metal ring having inner and outer surfaces, and a plurality of annularly disposed electromagnets on the inner surface of said metal ring energizible to provide a magnetic field directed substantially perpendicular to said surfaces of said ring; a disc connected to one edge of said ring and including an aperture which is concentric with the axis of said ring; a bearing carried on said disc and a shaft having one end thereof extending through said aperture and mounted in said bearing for rotation of said disc and ring thereabout and another end disposed within means for sequentially connecting said electromagnets to an electrical supply including a member fixed to said shaft and electrical contacts carried by said member for slidably engaging said electromagnets; a magnet and means for connection to a vehicle frame mounting said magnet within said ring below said shaft and adjacent said annular magnetic means, and magnet having a magnetic polarity such that a repelling force is provided between said magnet and said annular magnetic means, said mounting means including an arm extending below said shaft and having a bore therein; and a pin depending from said shaft and extending through said bore for permitting free movement between said magnet and said ring in response to loading changes of the vehicle.
