The invention relates to the field of torsion beam type suspension integration, in particular to a composite torsion beam trailing arm structure which comprises a trailing arm outer plate and a trailing arm inner plate formed in a punching mode. The outer surfaces of the trailing arm outer plate and the trailing arm inner plate are each provided with a positioning hole facilitating welding and positioning of a follow-up assembly. The trailing arm is changed from an integrated pipe fitting into a mode that a trailing arm outer plate and a trailing arm inner plate are respectively formed by stamping and then are welded and compounded, the trailing arm can be achieved through simple U-O forming, the forming process is simple, the design freedom degree is large, positioning hole face characteristics are designed on a stamping surface body, welding positioning of a follow-up assembly is facilitated, and the size is more stable; according to the trailing arm body in the form of the inner plate and the outer plate with the shock absorber mounting points, the stamping and welding procedures of an independent shock absorber support are omitted, the quality is more stable, the cost is lower, and the production efficiency is higher.

    本发明涉及扭力梁式悬架集成领域,具体是一种复合式扭力梁纵臂结构,包括冲压成型的纵臂外板、纵臂内板,所述的纵臂外板、纵臂内板外表面上均设置有利于后续总成焊接定位的定位孔,纵臂由一体式管件改为纵臂外板、纵臂内板分别冲压成型,再焊接复合的形式,可通过简单U‑O成型实现,成型工艺简单,设计自由度大,在冲压表面本体设计定位孔面特征,有利于后续总成焊接定位、尺寸更稳定;具有减震器安装点的内外板形式的纵臂本体,省去了独立减震器支架的冲压和焊接工序,质量更稳定、成本更低、生产效率更高。
