The invention relates to the technical field of front auxiliary frame machining, and particularly discloses a lightweight high-strength steel front auxiliary frame and an automobile. According to the light-weight high-strength steel front auxiliary frame, the high-strength steel material is adopted, the rigidity and strength performance of the front auxiliary frame are greatly improved, the overall performance requirement of the auxiliary frame is met, and safety is high. The lightweight high-strength steel front auxiliary frame comprises a left longitudinal beam, a right longitudinal beam, a front cross beam, a rear cross beam, a left front mounting bracket, a left lower mounting bracket, a left rear mounting bracket, a left claw, a right front mounting bracket, a right lower mounting bracket, a right rear mounting bracket and a right claw, the left longitudinal beam and the right longitudinal beam are bent pipe fittings. The mode that the bent pipe longitudinal beams and the metal plate transverse beams are combined is adopted, different welding modes are matched, and on the premise that the requirement for bearing loads is met, the structural stability is improved, and the machining cost is reduced. The front auxiliary frame solves the problems that an existing front auxiliary frame is high in machining cost and large in overall weight.
本发明涉及前副车架加工技术领域,具体公开了一种轻量化高强钢前副车架及汽车。本发明的轻量化高强钢前副车架采用高强钢材料,较大提升了前副车架的刚度和强度性能,满足副车架整车性能要求,安全性高。本发明的轻量化高强钢前副车架包括:左纵梁、右纵梁、前横梁、后横梁、左前安装支架、左下安装支架、左后安装支架、左羊角、右前安装支架、右下安装支架、右后安装支架、右羊角;其中,左纵梁、右纵梁均为弯管件。本发明采用弯管纵梁与钣金横梁相结合的方式,搭配不同的焊接形式,在满足承载载荷的前提下,提升了结构稳定性,降低了加工成本。本发明解决了现有的前副车架加工成本偏高、整体重量偏大的问题。
