Articulating wheeled permanent magnet chassis with high pressure sprayer

A magnetic vehicle comprising:

• a) a chassis including a drive motor and a plurality of axles which support a plurality of permanent magnet wheels;
• b) suspension comprising first and second torsion means for spring biasing first and second pairs of said axles which support a plurality of said wheels, and wherein each of said pairs of axles are coupled to one of first and second members which members rotate relative to one another and are coupled to one another with a plurality of springs;
• c) steering means for directing said chassis, wherein a servo motor is coupled to said drive motor and includes a screw follower means mounted to one of said first and second gear reduction means and coupled to said servo motor for extending and retracting said screw follower means to steer said chassis;
• and
• d) tool means for operating on a ferromagnetic work surface.

A magnetic vehicle comprising:

• a) a chassis including a drive motor and a plurality of axles which support a plurality of permanent magnet wheels, wherein each of said plurality of permanent magnet wheels comprises a plurality of pole sets that are coupled side by side to one another, wherein each pole set includes a plurality of magnetic pole pieces arranged about a bore of an annular keeper, wherein a peripheral surface of the adjacent keepers defines a rolling surface of the wheel, and wherein coupler means flexibly support each wheel to one of said axles such that each wheel can flex relative to the axle to adjust to a support surface;
• b) suspension means for resiliently supporting said wheels to said chassis;
• and
• c) steering means for directing said chassis.

A magnetic vehicle comprising:

• a) a chassis including a drive motor and a plurality of axles which support a plurality of permanent magnet wheels, wherein said chassis comprises first and second frame sections, wherein pivot means having a pivot pin couple said first and second frame sections to one another to articulate at said pivot pin about one another, wherein each permanent magnet wheel comprises a plurality of pole sets that are coupled side by side to one another, and wherein each pole set includes a plurality of magnetic pole pieces that are circumferentially arranged about a bore of an annular keeper such that a peripheral surface of each keeper defines a rolling surface of each wheel;
• b) suspension means for supporting said wheels to said chassis and including first and second torsion means for resiliently biasing drive axles mounted to said respective first and second sections relative to a rolling surface;
• and
• c) steering means for directing said chassis.
