The invention discloses an integrally-formed lightweight cast cross beam assembly comprising a cross beam part, a longitudinal beam connecting end panel and a balanced suspension connecting bottom panel that are integrally formed through a casting process. The cross beam part is transversely arranged in a length direction, the longitudinal beam connecting end panel is formed on the end faces of the two transverse sides of the cross beam part, and the balanced suspension connecting bottom panel is formed below the bottom face of the cross beam part. Compared with a stamped metal plate cross beam, the integrally-formed lightweight cast cross beam assembly is lighter and more convenient, and the fuel economy of a vehicle can be better improved; compared with a stamped metal plate cross beam,the stress is more uniform, and the torsion resistance is higher; the integrated and light-weight design is adopted, the longitudinal beam connecting end panel and the balanced suspension connecting bottom panel are integrated on the transverse beam part, so that mounting supports of a front-end mounting system are reduced, the self weight of the frame can be reduced, and the design, manufacturingand management cost is also reduced.

    本发明公开了一种一体成型轻量化铸造横梁总成,包括采用铸造工艺一体成型的横梁部、纵梁连接端面板及平衡悬架连接底面板,所述横梁部的长度方向横向设置,所述纵梁连接端面板形成于所述横梁部的横向两侧端面上,所述平衡悬架连接底面板形成于所述横梁部的底面下方。本发明的一体成型轻量化铸造横梁总成,相较于较冲压钣金横梁更加轻便,能够更好地提升车辆的燃油经济性;相较于冲压钣金横梁受力更均匀,抗扭转能力更强;采用集成化、轻量化设计,在横梁部上集成了纵梁连接端面板及平衡悬架连接底面板,减少了前端安装系统的安装支架,可降低车架自重,也降低了设计、制造和管理成本。
