Magnetic wheel

摘要

An improved magnetic wheel for a vehicle that moves over ferromagnetic surfaces. The vehicle includes an articulating, remotely controlled chassis that is constructed around a variable frequency motor. Drive axles extend from spring biased torsion hubs and are supported at resilient bushings at each wheel. Each wheel includes a number of adjoining annular permanent magnet pole sets. Permanent magnet disks are arrayed around the circumference of each pole set. At least one pole set is secured to a wheel hub and the others are supported from resiliently mounted registration pins. The resiliently mounted pole sets are able to flex with encountered irregularities at the work surface as the axle tracks and independently flexes with the surface changes.
