The invention discloses a railway vehicle and a bogie and a bogie cross beam thereof, the bogie cross beam is a carbon fiber cross beam formed by combining split structures and comprises a plurality of cavities arranged in the extending direction of a cross beam body, and the cavities are in a square shape; in the cross section of the bogie cross beam, a first mold cavity in the multiple mold cavities is located in the middle, other mold cavities in the multiple mold cavities are symmetrically formed in the two sides of the first mold cavity, and each side comprises at least two mold cavities which are arranged in an up-down overlapping mode; 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 effectively improved through structural optimization, and good assembly manufacturability is achieved.
本发明公开一种轨道车辆及其转向架、转向架横梁,该转向架横梁为由分体结构组合形成的碳纤维横梁,且包括沿横梁本体的延伸方向设置的多个型腔,所述型腔为“口”字型;在所述转向架横梁的横截面内,所述多个型腔中的第一型腔位于中部,所述多个型腔中的其他型腔对称设置在所述第一型腔的两侧,且每侧包括上下叠合设置的至少两个所述型腔;其中,所述第一型腔的中心位置处具有上下贯通的安装孔。本方案通过结构优化可有效提高横梁整体刚度,并具有较好的装配工艺性。
