The invention provides a beam assembly of a bogie, a framework, the bogie and a railway vehicle. The cross beam assembly of the bogie comprises a cross beam part integrally formed by carbon fibers to form a rectangular frame body, the interior of the cross beam part is divided into a plurality of cavities, and the cavities are of channel structures extending in the longitudinal direction of the bogie; the multiple cavities comprise a pair of first cavities, and in the cross section of the cross beam part, the pair of first cavities are symmetrically formed in the two transverse sides of the cross beam part correspondingly, so that a pair of longitudinal beam parts of the bogie can penetrate through and be connected into the pair of first cavities correspondingly. In the framework of the bogie, the longitudinal beam part can penetrate through the first cross beam, so that reliable connection of the cross beam part and the longitudinal beam part in the whole carbon fiber framework is realized. Therefore, on the basis of meeting the lightweight requirement of the railway vehicle, the cross beam assembly and the framework can realize the assembly universality, the connection reliability and the accuracy of the cross beam assembly and the longitudinal beams made of various materials, so that the running safety and the running stability of the bogie framework and even the whole bogie are improved.

    本发明提供一种转向架的横梁组成、构架及转向架、轨道车辆。该转向架的横梁组成包括由碳纤维一体成型构成矩形框体的横梁部,横梁部的内部被分隔成多个型腔,多个型腔均为沿转向架的纵向延伸的通道结构;多个型腔包括一对第一型腔,在横梁部的横截面内,一对第一型腔分别对称设置在横梁部的横向两侧,以使转向架的一对纵梁部能分别穿设并连接于一对第一型腔中。该转向架的构架中,纵梁部能穿过第一横梁,从而实现整个碳纤维构架中横梁部和纵梁部的可靠连接。由此,该横梁组成及构架能够在满足轨道车辆轻量化要求的基础上,实现横梁组成与多种材质纵梁的装配通用性、连接可靠性和准确性,进而提高转向架构架乃至整个转向架的运行安全性和平稳性。
