The bimetallic frame longitudinal member comprises an aluminum alloy longitudinal member body, the section of the aluminum alloy longitudinal member body is of a U-shaped structure, the aluminum alloy longitudinal member body comprises an upper wing plate, a lower wing plate and a web plate, the web plate is arranged between the upper wing plate and the lower wing plate, and the web plate is provided with a mounting groove used for mounting a steel plate in the length direction. The steel plate is inserted into the web from one end of the mounting groove. The steel plates are inserted into the web plates, so that the vertical bending rigidity of the frame is ensured while the light weight of the aluminum alloy frame longitudinal beam is realized; compared with the scheme of making up the rigidity by increasing the thickness, the cost is lower, and the weight is lighter; compared with a direct attaching technology, the appearance is more attractive, and galvanic corrosion can be effectively prevented.

    本发明涉及一种双金属车架纵梁,该双金属车架纵梁包括铝合金纵梁本体,铝合金纵梁本体截面呈U型结构,包括上翼板、下翼板和腹板,腹板设置在上翼板和下翼板之间,腹板沿长度方向设有用于安装钢板的安装槽,钢板从安装槽的一端插入腹板内。通过在腹板内插入钢板,在实现铝合金车架纵梁轻量化的同时,保证了车架的垂直弯曲刚度;相比通过增加厚度弥补刚度的方案,成本更低,重量更轻;相比直接贴合的工艺,该发明外观更加美观,能有效防止电偶腐蚀。
