The invention discloses a side beam of a bogie, the bogie, a rail vehicle and a forming process of the side beam. The side beam comprises a middle beam body and end beam bodies located at the two ends of the middle beam body, the middle beam body is used for being connected with a cross beam of the bogie, and the middle beam body and the end beam bodies are integrally made of fiber composite materials. The inner side of the middle beam body protrudes inwards relative to the inner sides of the adjacent end beam bodies to form a first-stage step part, the middle of the inner side of the middle beam body protrudes outwards relative to the first-stage step part to form a second-stage step part, and the first-stage step part corresponds to the position connected with a cross beam. the top of the two-stage step part is used for supporting an air spring which is eccentrically arranged. According to the scheme, the inner side of the side beam is provided with two steps, the thickness of the corresponding position of the side beam is increased through the first-stage step part so as to enhance the strength of the connecting position of the side beam and the cross beam, and the second-stage step part further protrudes inwards so as to provide enough supporting area to assist in supporting the air spring which is eccentrically arranged.

    本发明公开一种转向架的侧梁、转向架、轨道车辆和侧梁的成型工艺,所述侧梁包括中部梁体和位于所述中部梁体两端的端部梁体,所述中部梁体用于连接转向架的横梁,所述中部梁体和端部梁体由纤维复合材料一体制成,所述中部梁体内侧相对相邻所述端部梁体的内侧向内突出,形成一级台阶部,所述中部梁体内侧的中部相对所述一级台阶部向外突出形成二级台阶部,所述一级台阶部对应于和横梁连接的位置,所述二级台阶部的顶部用于支撑偏心设置的空簧。本方案中的侧梁内侧做了两级台阶设置,一级台阶部增加侧梁对应位置的厚度,以增强和横梁连接位置的强度,二级台阶部进一步内凸以提供足够的支撑面积以辅助支撑偏心设置的空簧。
