The invention discloses a front auxiliary frame structure combined by dissimilar materials, and belongs to the field of auxiliary frame structures. The front auxiliary frame structure comprises a front auxiliary frame assembly and an anti-collision beam assembly, wherein anti-rotation supports are welded at the two ends of a front cross beam body; one end of each of the two energy absorption boxesis connected with the anti-rotation support through a welding square nut; mounting plates are respectively arranged at the other ends of the two energy absorption boxes; the cross beam body is connected with a front longitudinal beam upper plate through a connecting piece; a front longitudinal beam lower plate is arranged at one end of the front longitudinal beam upper plate; the front longitudinal beam lower plate is fixedly connected with the front auxiliary frame assembly through bolts; mounting holes are formed in the two sides of the anti-collision beam assembly; and the anti-collision beam assembly is fixedly connected with the mounting plates arranged on the energy absorption boxes through the mounting holes in the two sides in cooperation with bolts. The structure is convenient todisassemble and assemble, the manufacturing is easy, the process is easy to achieve, the anti-collision beam assembly and the front longitudinal beam are additionally arranged so as to enable the front auxiliary frame assembly to participate in energy absorption earlier, and thus the anti-collision effect is improved.

    本发明公开了一种异种材料结合的前副车架结构,属于副车架结构领域,包括前副车架总成和防撞梁总成,所述前横梁本体的两端均焊接有防转支架,两个所述吸能盒的一端分别通过焊接方螺母与防转支架连接,两个所述吸能盒的另一端分别设有安装板,所述横梁本体通过连接件与前纵梁上板连接,所述前纵梁上板的一端设有前纵梁下板,所述前纵梁下板通过螺栓与前副车架总成连接固定,所述防撞梁总成的两侧均开设有安装孔,所述防撞梁总成通过两侧的安装孔配合螺栓与设置在吸能盒上的安装板固定连接。本发明结构拆装方便,且易于制造,工艺易于实现,增设防撞梁总成与前纵梁使前副车架总成能够更早地参与能量吸收,以此来提高防冲撞的效果。
