The invention relates to a magnetic levitation spring for a railway vehicle. The magnetic levitation spring comprises a vehicle body mounting end and a bogie mounting end, wherein the vehicle body mounting end comprises a vehicle body mounting end body, first transverse and longitudinal electromagnet units and an upper vertical actuating coil, the first transverse and longitudinal electromagnet units are uniformly distributed on the vehicle body mounting end body, and the upper vertical actuating coil is arranged on the vehicle body mounting end body; a bogie mounting end comprises a bogie mounting end body, an actuating part, second transverse and longitudinal electromagnet units and a lower vertical actuating coil, the second transverse and longitudinal electromagnet units are uniformly distributed on the actuating part and used in cooperation with the first transverse and longitudinal electromagnet units, and the lower vertical actuating coil is arranged on the bogie mounting end body; and sensors are arranged on the vehicle body mounting end body and the bogie mounting end body. The magnetic levitation spring can suspend a vehicle body to a certain height based on electromagnetic force, multi-direction freedom degree control is achieved, vertical rigidity, longitudinal rigidity and transverse rigidity are adjusted, and the vibration reduction effect and the curve passing requirement of the railway vehicle are improved.

    本发明涉及一种轨道车辆用磁浮弹簧,包括:车体安装端、转向架安装端;车体安装端包括车体安装端本体、第一横纵向电磁铁单元、上部垂向作动线圈,第一横纵向电磁铁单元均布在车体安装端本体上,上部垂向作动线圈布置在车体安装端本体上;转向架安装端包括转向架安装端本体、作动部件、第二横纵向电磁铁单元、下部垂向作动线圈,第二横纵向电磁铁单元均布在作动部件上,与第一横纵向电磁铁单元配对使用,下部垂向作动线圈布置在转向架安装端本体上;车体安装端本体和转向架安装端本体上均布置有传感器。该磁浮弹簧基于电磁力,可将车体悬浮至一定高度,实现多向自由度控制,调整垂向、纵向和横向刚度,改善轨道车辆减振效果和过弯道需求。
