The invention discloses a railway vehicle and a bogie, a bogie cross beam and a bogie cross beam module thereof. The bogie cross beam comprises a carbon fiber beam body with three cavities, and the three cavities are arranged in the extending direction of a cross beam body; in the cross section of the bogie cross beam, the first cavity in the three cavities is located in the middle, and the second cavity and the third cavity in the three cavities are symmetrically formed in the two sides of the first cavity; wherein a mounting hole which is through up and down is formed in the center position of the first cavity. According to the scheme, the overall rigidity of the cross beam can be improved on the whole, and the cross beam has good bearing capacity on the basis of meeting the final assembly design requirement; meanwhile, the weight of the cross beam can be reduced based on the carbon fiber material, and good assembly manufacturability is achieved. Meanwhile, the bogie cross beam module is provided with the additional air chamber in an integrated mode, the assembly space of the bogie cross beam can be further fully utilized, and the good integration degree is achieved.

    本发明公开一种轨道车辆及其转向架、转向架横梁、转向架横梁模组,该转向架横梁包括具有三个型腔的碳纤维梁体,且所述三个型腔沿横梁本体的延伸方向设置;在所述转向架横梁的横截面内,所述三个型腔中的第一型腔位于中部,所述三个型腔中的第二型腔和第三型腔对称设置在所述第一型腔的两侧;其中,所述第一型腔的中心位置处具有上下贯通的安装孔。本方案整体上可提高横梁的整体刚度,在满足总装设计要求的基础上,具有较好的承载能力;同时基于碳纤维材质可降低横梁重量,具有较好的装配工艺性。同时,转向架横梁模组集成配置有附加气室,可进一步充分利用转向架横梁的组装空间,具有较好的集成度。
