The invention provides a magnetorheological fluid-based bidirectional variable-stiffness tumbler rubber node, a bogie and a rail train, and the bidirectional variable-stiffness tumbler rubber node comprises a cylindrical shell suitable for being clamped and embedded on a swing arm; the node core shaft is sleeved with the shell, and a through hole is formed in the node core shaft in the radial direction; the rubber layer is filled between the shell and the joint mandrel; the magneto-rheological damper is clamped in the through hole, the magneto-rheological damper comprises a piston rod arranged in the axial direction of the through hole, the two ends of the piston rod abut against the rubber layers respectively, and the interior of a mouth of the magneto-rheological damper can be adjusted bidirectionally. When the train runs linearly at a high speed, large rigidity can be provided to ensure the high-speed stability of the train, and when the train runs on a curve track, the rigidity is reduced to meet the requirement of curve trafficability.

    本公开提供了一种基于磁流变液的双向变刚度转臂橡胶节点、转向架及轨道列车,双向变刚度转臂橡胶节点包括:外壳,呈筒状,适用于卡嵌在摆动臂上;节点芯轴,套设在外壳内部,节点芯轴上沿径向方向开设有通孔;橡胶层,填充在外壳与节点芯轴之间;磁流变阻尼器,卡设在通孔内,磁流变阻尼器包括沿通孔轴向设置的活塞杆,活塞杆两端分别抵靠在橡胶层上,磁流变阻尼器的嘴里双向可调节。在列车直线高速行驶时可以提供较大刚度保证列车的高速稳定性,而在曲线轨道运行时降低刚度满足曲线通过性的要求。
