The invention discloses a lightweight trailer frame which is characterized in that the trailer frame is formed by fixedly connecting a left longitudinal beam, a right longitudinal beam, a plurality of cross beams, a traction seat plate and a plurality of suspension brackets, a plurality of special-shaped holes are formed in the longitudinal beams and the cross beams, the distance between the rear portions of the two longitudinal beams is larger than the distance between the front portions of the two longitudinal beams, front upper wing plates of the longitudinal beams are of bent structures, and the thickness of the front upper wing plates is larger than that of rear upper wing plates. Under the same weight, the maximum bearing capacity is obtained; and meanwhile, punching design is carried out on the web plate and the cross beam to further reduce weight, and in order to enable punching not to affect strength, a combined hole method is adopted to replace a single-hole design.
本发明公开了一种轻量化挂车车架,其特点是,挂车车架由相互对称的左纵梁与右纵梁、若干与纵梁垂直放置的横梁、一个牵引座板及若干悬挂支架固定连接;在纵梁、横梁上设有若干异型孔,两纵梁之间后部的距离大于前部距离,纵梁前部上翼板采用折弯结构,且前部上翼板厚度大于后部上翼板厚度;在同样重量下,取得最大的承载能力;同时在腹板、横梁上进行打孔设计来进一步轻量化,为了使打孔不影响强度,采用了组合孔的方法来替代单孔的设计。
