The invention relates to an axle box positioning method, an axle box overhead node and a rail vehicle, the axle box is located by arranging an axle box overhead rubber node with small vertical rigidity and large radial rigidity at the top of the axle box, so that the vertical rigidity, the longitudinal rigidity and the transverse rigidity of an axle box spring can be decoupled, and the positioningstructure of the axle box is simplified; and the cost is reduced. The axle box overhead joint is of a metal rubber composite structure with multiple layers of annular spacer bushes, and the spacer bushes are of a split structure so that the axle box overhead rubber joint can be pre-compressed, and the radial rigidity can be further improved. Meanwhile, an axial cavity is formed in the axle box overhead rubber joint, so that the rigidity of the axle box overhead joint in different radial directions is different, and different rigidity requirements required by axle box positioning in the longitudinal direction and the transverse direction are met.

    本发明涉及一种轴箱定位方法及轴箱顶置节点和轨道车辆,通过在轴箱的顶部设置垂向刚度小、径向刚度大的轴箱顶置橡胶节点的方式对轴箱进行定位,能够使轴箱弹簧的垂向刚度与纵向刚度及横向刚度解耦,简化了轴箱的定位结构,降低了成本。所述轴箱顶置节点采用多层圆环形隔套的金属橡胶复合结构,所述隔套采用分瓣式结构,以便对轴箱顶置橡胶节点进行预压缩,以进一步提高径向刚度;同时在轴箱顶置橡胶节点设置有轴向空腔,以实现轴箱顶置节点在不同的径向方向的刚度不同,以满足轴箱定位沿纵向和横向所需的不同刚度要求。
