The invention relates to the technical field of manufacturing and production of automobiles and auxiliary frames, in particular to a three-beam-body front auxiliary frame of a new energy electric automobile. The invention relates to a three-beam body front auxiliary frame of a new energy electric vehicle, which can further improve the structural performance modality, rigidity and strength compared with the prior art after the load weight is increased, and comprises a butterfly-shaped or frame body frame structure consisting of a front cross beam, a rear cross beam, a left longitudinal beam and a right longitudinal beam, comprising a longitudinal beam upper plate, a longitudinal beam lower head plate and a longitudinal beam lower tail plate, a cross beam arch groove is formed in the head end of the longitudinal beam upper plate, the longitudinal beam lower head plate is spliced on the front side of the cross beam arch groove with the cross beam arch groove as the boundary below the longitudinal beam upper plate, and the longitudinal beam lower tail plate is spliced on the rear side of the cross beam arch groove, so that a lower plate body is formed; therefore, a left longitudinal beam or a right longitudinal beam with a cross beam arch groove is spliced; the front cross beam is of a pipe body structure, and the head end and the tail end are inserted into mounting bases or mounting grooves arranged at the head ends of the left longitudinal beam and the right longitudinal beam.
本发明涉及汽车、副车架制造和生产技术领域,具体为一种新能源电动汽车三梁体前副车架。能对应在负载重量上升后,结构性能模态、刚度、强度还能比现有技术有进一步提升的新能源电动汽车三梁体前副车架,包括由前横梁、后横梁、左纵梁、右纵梁组成蝶形或框体车架结构,其中:所述左纵梁、右纵梁为结构一致互为对称结构,包括纵梁上板、纵梁下头板、纵梁下尾板,纵梁上板头端设置横梁拱槽,纵梁上板的下方以横梁拱槽为界,在横梁拱槽的前侧拼接纵梁下头板,后侧拼接纵梁下尾板,由此组成一个下板体,然后一个整体的下板和纵梁上板上下拼合,由此拼接出留有横梁拱槽的左纵梁或右纵梁;所述前横梁为管体结构,头尾两端插入左纵梁和右纵梁头端设置的安装座或安装槽内。
