The invention belongs to the technical field of trailer assemblies, in particular to a semitrailer longitudinal beam assembly, which comprises a front beam, a rear beam, a reinforced buffer structure,a wire clamp structure and damping structures, wherein the damping structures are respectively mounted at the bottoms of the front beam and the rear beam; the damping structure comprises a damper, anI-shaped mounting rail, a swing rod, a pin shaft, a sliding block and a supporting plate. Long-strip sliding grooves are formed in the side portions of the bottoms of the two ends of the front beam and the side portions of the bottoms of the two ends of the rear beam respectively, sliding blocks are slidably connected into the long-strip sliding grooves, dampers are connected to one side walls inthe long-strip sliding grooves, the damping ends of the dampers are fixedly connected with the adjacent side faces of the sliding blocks, and I-shaped mounting rails are arranged below the rear beamand the front beam respectively. The semitrailer longitudinal beam assembly has the advantages that through the front beam and rear beam bottom damping structures, bumping force generated in the vertical direction and inertia force generated in the horizontal direction can be buffered, the buffering possibility is increased, the damping effect is improved, the damage possibility is reduced, and the service life is prolonged.

    本发明属于挂车组件技术领域,具体的说是一种半挂车纵梁总成,包括前梁、后梁、加固缓冲结构、线夹结构和减震结构,前梁底部和后梁底部分别安装减震结构,减震结构包括减震器、工字型安装轨、摆动杆、销轴、滑块和支撑板,前梁和后梁的两端底部侧部分别设有长条滑槽,长条滑槽的内部滑动连接滑块,长条滑槽内部一侧壁连接减震器,减震器的减震端与滑块相邻的侧面固定连接,后梁和前梁下方分别设有工字型安装轨。本发明提供的半挂车纵梁总成具有通过前梁和后梁底部减震结构,能够对竖直方向产生颠簸力和水平方向产生惯性力都能够进行缓冲,缓冲可能性增加,提高减震效果,降低损坏可能性,提高使用寿命的优点。
