The invention belongs to the technical field of commercial vehicles, and discloses a connecting structure, a frame assembly and a commercial vehicle. The connecting structure comprises an integrally-formed square connecting body, the square connecting body comprises a first wing plate, a second wing plate, a first web plate and a second web plate, the first wing plate and the second wing plate are parallel and distributed at intervals, and the first web plate and the second web plate are parallel and distributed at intervals. Two ends of the second web plate are respectively connected with the first wing plate and the second wing plate; the thickness of the first wing plate is larger than or equal to that of the second wing plate, the first wing plate is used for being connected with the upper end of a middle frame, and the second wing plate is used for being connected with the lower end of the middle frame. The thickness of the first web is larger than or equal to that of the second web, and the first web is used for being connected with a frame longitudinal beam. The weight and the production cost of the connecting structure can be effectively reduced, and the bearing capacity, the structural strength and the torsion resistance of the assembled and formed frame assembly can be effectively improved.

    本发明属于商用车技术领域,公开了连接结构、车架总成及商用车。该连接结构包括一体成型的方型连接本体,方型连接本体包括平行且间隔分布的第一翼板和第二翼板,以及平行且间隔分布的第一腹板和第二腹板,第一腹板的两端分别与第一翼板和第二翼板连接,第二腹板的两端分别与第一翼板和第二翼板连接;第一翼板的厚度大于等于第二翼板的厚度,第一翼板用于与中车架的上端连接,第二翼板用于与中车架的下端连接;第一腹板的厚度大于等于第二腹板的厚度,第一腹板用于与车架纵梁连接。能够有效降低连接结构的重量和生产成本,且能够有效提升组装成型的车架总成的承载能力、结构强度和抗扭能力。
