The invention relates to the field of railway vehicles, and provides a primary suspension positioning structure, a bogie and a railway vehicle. The primary suspension positioning structure comprises a pair of fork arms, each fork arm comprises a single-arm end and a double-arm end connected to the single-arm end, the single-arm ends are connected to a shaft sleeve of an axle, the double-arm ends are connected to a framework of the bogie, and the primary suspension is suitable for achieving longitudinal, radial and vertical positioning with the framework through the pair of fork arms; and one side of the motor is mounted on the shaft sleeve, and the other side of the motor is connected to the framework. According to the primary suspension positioning structure, accurate positioning in the longitudinal direction, the radial direction and the vertical direction between a primary suspension system and a framework of the bogie is achieved through connection of the pair of fork arms; in this way, the mode that positioning is achieved through an axle box body in the related technology can be changed, due to the fact that the axle box body is omitted, the structure can be simplified, and light-weight design can be achieved easily; the complexity of the primary suspension positioning structure is simplified, the number of required parts is reduced, and the weight of the whole vehicle is also reduced.

    本发明涉及轨道车辆领域,提供一种一系悬挂定位结构、转向架及轨道车辆。一系悬挂定位结构包括一对叉臂,叉臂包括单臂端以及连接于单臂端的双臂端,单臂端连接于车轴的轴套,双臂端连接于转向架的构架,一系悬挂适于通过一对叉臂实现与构架的纵向、径向以及垂向定位;电机,电机的一侧安装于轴套,电机的另一侧连接于构架。该一系悬挂定位结构通过一对叉臂的连接就实现了一系悬挂系统与转向架的构架之间的纵向、径向以及垂向的精确定位;即可改变相关技术中通过轴箱体实现定位的方式,由于省却了轴箱体的设置,可以简化结构、有利于实现轻量化的设计;简化了该一系悬挂定位结构的复杂度,减少了所需部件的数量,还降低了整车的重量。
