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.
