The invention discloses a lightweight traction beam assembly for a heavy-duty truck. Comprising an impact seat assembly, a rear slave plate assembly and a center plate partition plate assembly. The traction beam assembly is of a box-shaped structure formed by welding a lower cover plate, two web plates symmetrically assembled on the two sides of the lower cover plate, the top face and a truck floor. The striker assembly is welded and fixed at the front end of the box-shaped structure of the traction beam assembly, the rear slave plate assembly is welded and arranged in the middle of the box-shaped structure of the traction beam assembly, the center plate partition plate assembly is arranged at the rear end of the rear slave plate assembly of the box-shaped structure of the traction beam assembly, and the lower part of the center plate partition plate assembly is connected and fixed with the upper center plate; a crack arrest hole is formed in the corner of the end part of the notch groove of the lower cover plate. On the premise that the strength is met, an upper cover plate is omitted, the traction beam assembly and the floor form a box-type section structure, an assembly welding type rear slave plate seat is assembled, the self weight is light, and maintenance is convenient; the center plate partition plate assembly adopts an assembly welding piece and is matched with the split type upper center plate for use, so that the self weight is effectively reduced; and crack arrest holes are additionally formed in the right-angle corners of the lower cover plate to solve the problem of cracks.
本发明公开了一种重载货车用轻量化牵引梁组成。包括冲击座组成、后从板组成、心盘隔板组成;牵引梁组成由下盖板、下盖板两侧对称组装的两块腹板、顶面与货车地板组焊成箱型结构;冲击座组成焊接固定于牵引梁组成箱型结构的前端,后从板组成焊接布置于牵引梁组成箱型结构的中部,心盘隔板组成布置于牵引梁组成箱型结构后从板组成的后端、下部与上心盘连接固定;下盖板缺口槽的端部转角处设置止裂孔。本发明牵引梁组成在满足强度的前提下,取消上盖板并与地板组成箱型断面结构,装配组焊式后从板座,自重轻,便于维护;心盘隔板组成采用组焊件,与分体式上心盘配合使用,有效减少自重;下盖板在直角拐角处增设止裂孔以解决出现裂纹的问题。
