The invention relates to a permanent magnet maglev train which comprises a train body, permanent magnet rails and sleepers, a linear motor primary is arranged in the middle of the bottom of a suspension frame, vehicle-mounted permanent magnets are arranged on the two sides of the bottom of the suspension frame respectively, and the vehicle-mounted permanent magnets on the two sides are located over the corresponding permanent magnet rails respectively; a linear motor secondary is laid in the middle of the line, and the linear motor secondary is located under the linear motor primary at the bottom of the suspension frame; steel rails are laid on the two sides of the line respectively, supporting wheels and guide wheels are arranged on the two sides of the bottom of the suspension frame respectively, the supporting wheels are connected to the top faces of the corresponding steel rails in a rolling mode, and the guide wheels are connected to the outer side faces of the corresponding steel rails in a rolling mode. The vehicle-mounted permanent magnets on the two sides and the corresponding lower permanent magnet rails are arranged in a staggered and offset mode. According to the invention, the vehicle-mounted permanent magnets on the vehicle body and the corresponding permanent magnet tracks below adopt a staggered bias design, so that the influence of the guiding force (transverse force) of the permanent magnet magnetic suspension system on the stability of the system can be reduced.

    本发明涉及一种永磁磁悬浮列车,包括车体、永磁轨道和轨枕,悬浮架的底部中间设置有直线电机初级,悬浮架的底部两侧分别设置有车载永磁体,两侧的车载永磁体分别位于对应永磁轨道的正上方;沿线路中间铺设有直线电机次级,所述直线电机次级位于悬浮架底部直线电机初级的正下方;沿线路的两侧分别铺设有钢轨,所述悬浮架的底部两侧分别设有支撑轮和导向轮,支撑轮滚动连接于对应钢轨的顶面,导向轮滚动连接于对应钢轨的外侧面;两侧的车载永磁体与对应下方的永磁轨道错位偏移设置。本发明车体上的车载永磁体与对应下方的永磁轨道采用错位偏置设计,可以降低永磁磁悬浮系统的导向力(横向力)对系统稳定性的影响。
