The invention belongs to the technical field of frames, and discloses a longitudinal beam structure, a frame assembly and a longitudinal beam structure manufacturing method. The longitudinal beam structure comprises a first structural part and a second structural part. The first structural member comprises a first box-shaped part and a first groove-shaped part which are connected in sequence, and the first groove-shaped part is connected above the first box-shaped part in the Z direction; the second structural member comprises a second box-shaped part, and the first box-shaped part is connected to the second box-shaped part in a buckled mode to form a longitudinal beam cavity. The longitudinal beam structure can ensure the bending resistance and torsion resistance of the longitudinal beam structure, and is beneficial to realizing the light weight target and improving the assembly manufacturability of the vehicle.

    本发明属于车架技术领域,公开了一种纵梁结构、车架总成及纵梁结构制造方法。该纵梁结构包括第一结构件和第二结构件;该第一结构件包括依次衔接的第一盒形部和第一槽形部,该第一槽形部在Z方向上衔接于该第一盒形部的上方;该第二结构件包括第二盒形部,该第一盒形部扣合连接于该第二盒形部,形成纵梁空腔。该纵梁结构能够保证自身抗弯和抗扭能力,且有利于实现轻量化目标,改善车辆装配工艺性。
