The invention relates to the technical field of railway vehicles, in particular to an end chassis, a vehicle body and a railway vehicle, the end chassis comprises a cross beam, the cross beam is suitable for being connected with a chassis main body of the vehicle body, the cross beam comprises a first beam part and second beam parts, the first beam part is located below the second beam parts, and the two second beam parts are symmetrically connected to the two ends of the first beam part; the connecting beam extends in the length direction of the vehicle body; and the end beam is suitable for being connected with the chassis main body of the adjacent vehicle body, and the end beam is connected with the first beam part through a connecting beam. According to the end chassis, the overall force transmission structure of the chassis is optimized by arranging the cross beams with height changes, so that the space of the end chassis is reasonably optimized, and the number of the cross beams in a traditional chassis structure can be more reasonably and greatly reduced on the basis of at least guaranteeing the original load strength by adding a small number of camber beams in the end chassis, so that the cost is reduced. Therefore, the aim of train lightweight is achieved.

    本发明涉及轨道车辆技术领域,尤其涉及一种端部底架、车体及轨道车辆,端部底架包括:横梁,横梁适于与车体的底架主体连接,横梁包括第一梁部和第二梁部,第一梁部位于第二梁部的下方,两个第二梁部对称连接于第一梁部的两端;连接梁,连接梁沿车体的长度方向延伸;端梁,端梁适于与相邻的车体的底架主体连接,端梁通过连接梁与第一梁部连接。端部底架通过设置具有高度变化的横梁优化底架整体的传力结构,使得端部底架空间合理优化,并且通过在端部底架中增加少量弯梁可以在至少保证原有载荷强度的基础上,更合理的大幅减少传统底架结构中的横梁数量,从而实现列车轻量化目标。
