The invention relates to the technical field of front auxiliary frames and new energy automobile parts, in particular to a narrow I-shaped combined front auxiliary frame. A narrow-body wide-width middle cross beam structure is adopted, the defects that an all-metal-plate front auxiliary frame is large in weight and large in occupied space are overcome, battery placement of an electric automobile cannot be affected, and the endurance mileage of a new energy automobile is increased. Comprising a left longitudinal beam, a right longitudinal beam and a main cross beam, the left longitudinal beam and the right longitudinal beam are of pipe body structures, and the main cross beam is composed of an upper metal plate and a lower metal plate and comprises a main cross beam upper plate and a main cross beam lower plate; a reinforcing support table is arranged in the middle of the main cross beam upper plate in a protruding mode, and the two ends of the reinforcing support table extend to the position between the longitudinal arm upper plate and the longitudinal arm lower plate and are connected with the longitudinal arm upper plate and the longitudinal arm lower plate. A traction seat hole is formed in the main cross beam upper plate on the reinforcing bracket; the head ends of the left longitudinal beam and the right longitudinal beam are folded inwards to be provided with L-shaped narrow-opening connecting pipes, and control arm mounting supports are obliquely arranged above the L-shaped narrow-opening connecting pipes.

    本发明涉及前副车架和新能源汽车部件技术领域,特别涉及一种窄体工字组合前副车架。采用窄体宽幅中横梁结构,实现解决全钣金片板前副车架重量大同时占用空间大缺点,不会影响电动汽车的电池安放,增加了新能源汽车续航里程。包括左纵梁、右纵梁和主横梁,所述左纵梁、右纵梁为管体结构,主横梁由上下两块金属板体钣金构成包括:主横梁上板和主横梁下板两个结构;所述主横梁上板的中间凸起设有增强支架台,所述增强支架台的两端延伸至纵臂上板和纵臂下板之间并与之连接;主横梁上板位于增强支架的上设置有牵引座孔;左纵梁、右纵梁的头端内折设置有L形的窄口接道管,并在其上方斜向设置控制臂安装支架。
