A permanent magnetic levitation system, comprising:
- a track unit comprising:
- a beam used as a base;
- a suspending arch crosstie connected fixedly to a bottom of the beam and having first and second ends at an open side thereof;
- first and second balancing guide levitation rails which are disposed symmetrically in waist portions at inner sides of the suspending arch crosstie, made of ferromagnetic materials, and each have a concave cross-section, respectively;
- first and second permanent magnetic rails which are disposed on upper surfaces of the first and second ends of the suspending arch crosstie respectively;
- and
- first and second auxiliary guide rails which are disposed on end surfaces of the first and second ends respectively in which the end surface of the first end faces that of the second end;
- and
- a vehicle unit comprising:
- a compartment;
- a magnetic levitation cabin which is integrated with the compartment, has first and second outer sides opposed to each other, and is formed with first and second protrusion portions at the first and second outer sides respectively;
- first and second magnetically conductive bases which are fixed to outer sides of the first and second protrusion portions respectively;
- first and second pairs of balancing permanent magnets which are symmetrical, the first pair of balancing permanent magnets being fixed to the first magnetically conductive base and comprised of a first lower balancing permanent magnet and a first upper balancing permanent magnet located above the first lower balancing permanent magnet, the first lower and upper balancing permanent magnets having opposite magnetic poles to each other, and the second pair of balancing permanent magnets being fixed to the second magnetically conductive base and comprised of a second lower balancing permanent magnet and a second upper balancing permanent magnet located above the second lower balancing permanent magnet, the second lower and upper balancing permanent magnets having opposite magnetic poles to each other;
- first and second guide wheels, the first guide wheel being disposed between the first lower and upper balancing permanent magnets, and the second guide wheel being disposed between the second lower and upper balancing permanent magnets;
- first and second wing magnet bases which are disposed respectively on bottom surfaces of the first and second protrusion portions;
- first and second wing magnets which are disposed respectively on bottom surfaces of the first and second wing magnet bases;
- first and second sliding shoes, the first sliding shoe being disposed between the first wing magnet base and the first outer side of the magnetic levitation cabin, and the second sliding shoe being disposed between the second wing magnet base and the second outer side of the magnetic levitation cabin;
- and
- first and second auxiliary guide wheels which are symmetrically disposed between a lower portion of the magnetic levitation cabin and the compartment;
- wherein the magnetic levitation cabin is levitated in the suspending arch crosstie, the first pair of balancing permanent magnets correspond to the first balancing guide levitation rail and are spaced a gap of approximate 5 to 60 mm apart from the first balancing guide levitation rail, and the second pair of balancing permanent magnets correspond to the second balancing guide levitation rail and are spaced a gap of approximate 5 to 60 mm apart from the second balancing guide levitation rail;
- the first wing magnet corresponds to, and is located above and spaced a gap of approximate 2 to 60 mm apart from the first permanent magnetic rail, and the second wing magnet corresponds to, and is located above and spaced a gap of approximate 2 to 60 mm apart from the second permanent magnetic rail;
- the first and second guide wheels are respectively supported in concave portions of the first and second balancing guide levitation rails so as to control the vehicle unit to be positioned centrally in the suspending arch crosstie;
- the first and second auxiliary guide wheels correspond to and are spaced a gap of approximate 2 to 10 mm apart from the first and second auxiliary guide rails, respectively,
- thereby the vehicle unit is held in a levitation state at a balancing position by levitation repulsion forces generated respectively between the first and second wing magnets and the first and second permanent magnetic rails, and balancing attraction forces generated respectively between the first and second pairs of balancing permanent magnets and the first and second balancing guide levitation rails.
