The invention relates to a lightweight frame of a road transportation dumper, which belongs to the technical field of dumper bearing and comprises a left longitudinal beam and a right longitudinal beam, and an I-type cross beam assembly, an II-type cross beam assembly, a cast cross beam assembly and a tail beam assembly are sequentially connected between the left longitudinal beam and the right longitudinal beam from front to back; the I-type cross beam assembly is arranged corresponding to the center line of a second axle of the vehicle; the cast cross beam assembly is arranged in the center of a double-rear-axle balance shaft suspension of the vehicle, and the second cross beam assembly and the tail beam assembly are correspondingly arranged on the front side and the rear side of the double-rear-axle balance shaft suspension respectively. The left longitudinal beam, the right longitudinal beam and the transverse beam body located in the middle are all of a single-layer structure and correspond to the two axles of the front section of the frame in cooperation with the I-type beam assembly, and the loading capacity of the front end of the frame is improved. The II-type cross beam assembly, the casting cross beam assembly and the tail beam assembly correspond to the front position, the middle position and the rear position of the double-rear-axle balance shaft suspension respectively, the position of a frame where the cargo carrying gravity center is concentrated is lifted, and therefore the self weight is reduced, and the loading capacity is improved.
本发明所述的一种公路运输自卸车轻量化车架,属于自卸车承载技术领域,包括左纵梁和右纵梁,所述左纵梁与右纵梁之间由前至后依次连接有Ⅰ型横梁总成、Ⅱ型横梁总成、铸造横梁总成及尾梁总成;所述Ⅰ型横梁总成与车辆二桥的中心线对应设置;所述铸造横梁总成设置于车辆的双后桥平衡轴悬架中心处,横梁总成二和尾梁总成分别对应设置在双后桥平衡轴悬架的前后两侧。左纵梁、右纵梁及处于中间的横向梁体均为单层结构,配合Ⅰ型横梁总成与车架前段二桥对应,提升了车架前端的载重能力;Ⅱ型横梁总成、铸造横梁总成及尾梁总成分别与双后桥平衡轴悬架的前中后三个位置对应,提升了载货重心集中的车架位置,进而实现了降低自重提升载重能力。
