A hidden-rail dual-attraction balancing compensation type permanent magnetic levitation train and railway system are provided. The hidden rails are provided inside two underground tubes, and each tube is communicated with the ground via a rail through silt. A magnetically conductive wing rail is mounted at each inner side surface of the tube and a central portion of the magnetically conductive wing rail is used as a guide rail, magnetically conductive plate rails are provided on a top inner surface of each tube and arranged at two side of the rail through slit, each vehicle of the train comprises two underground magnetic levitation power cabins located inside the tubes respectively and an aboveground car which are connected integrally to each other via web girder in the shape of a plate therebetween, a top permanent magnet is mounted on a top outer surface of each magnetic levitation power cabin and face a plane of the magnetically conductive plate rail, and two wing permanent magnets are fixed at each outer side surface of the magnetic levitation power cabin and correspond to the magnetically conductive wing rails. A set of power units and two sets of guide fixed pulleys are disposed inside each magnetic levitation power cabin, in which the guide fixed pulleys are contacted with the guide rails on both side inner surfaces of each tube. |
