  • Patent number: 7624686
    Abstract: A magnetic levitation bogie apparatus includes an upper inner circular ring permanent magnet mounted onto a bottom surface of a chassis; a bogie located below the chassis; a lower inner circular ring permanent magnet mounted onto an upper surface of the bogie, and aligned substantially with and spaced from the upper inner permanent magnet at a predetermined distance; an upper sleeve being mounted onto the chassis and coaxial with the upper inner permanent magnet; a lower sleeve being mounted onto the bogie and coaxial with the lower inner permanent magnet; and a rotation shaft coupled between the upper sleeve and the lower sleeve. The bogie apparatus of the present invention is simple in structure, long in life duration, low in cost, superior in vibration-damping effect, thus achieving good comfortableness of the vehicle.

  • Patent number: 7587982
    Abstract: A magnetic levitation guideway-train system is provided. The levitation power chambers located at a lower portion of the train are fitted in the grooved guideway, and the side permanent magnets of the levitation power chambers and the ferromagnetic balance levitation tracks correspond to one another so as to generate upward or downward balance attractive force for the train. Wing permanent magnets at the bottom of the levitation power chamber and the permanent magnet tracks correspond to one another so that the identical poles of the wing permanent magnets and the permanent magnet tracks repel one another to provide the train with an upward repulsion levitation force.

  • Patent number: 7527001
    Abstract: A bogie apparatus includes a chassis, rotation bogie parts respectively disposed at both ends of the chassis, and a composite motion bogie part located at a middle portion of the chassis. Each of said rotation bogie parts includes a circular upper inner ring permanent magnet fixed on a lower surface or a bottom surface of the chassis. A first bogie located under the chassis and having a bogie body is also added. A circular lower inner ring permanent magnet disposed on an upper surface or a top surface of the bogie body of the first bogie may be included. The inner ring may have inner and outer diameters substantially identical to those of the upper inner ring permanent magnet, and aligned with the upper inner ring permanent with a predetermined distance therebetween.

  • Patent number: 7520227
    Abstract: The present invention discloses a seal and connection device between train compartments comprised of a ? shaped rubber groove having two groove walls and a groove bottom. A width between the two groove walls is substantially equal to that of a slit between two neighboring compartments. The two groove walls can be fixed to ends of the two neighboring compartments respectively and the groove bottom are extended toward two ends thereof to form groove brims so that the groove brims can abut against end side walls of the compartments tightly.
