The invention discloses a platform rear auxiliary frame structure, the middle part of a rear auxiliary frame is of a hollow frame-shaped structure, the structure is formed by welding and connecting a front cross beam, a rear cross beam, a left longitudinal beam and a right longitudinal beam, and at least two reinforcing pieces are arranged in the frame-shaped structure of the rear auxiliary frame; and one ends of the two reinforcing pieces are welded on the front cross beam, and the other ends of the two reinforcing pieces are respectively welded on the left longitudinal beam and the right longitudinal beam, so that the reinforcing pieces define two triangular spaces on the rear auxiliary frame. By the adoption of the platform rear auxiliary frame structure, the two triangular spaces are formed on the rear auxiliary frame through the reinforcing pieces, the triangular structures are stable, and the rear auxiliary frame has high strength, NVH and operation stability; in addition, the reinforcing pieces are only located at the two corners of the rear auxiliary frame, a large enough space is reserved in the middle of the rear auxiliary frame, the space requirements of driving motors of multiple models can be met, and the universality of the rear auxiliary frame is enhanced. Due to the multifunctionality of a motor mounting bracket and a rear cross beam hole, different power configuration requirements are met, and the platformization of the rear auxiliary frame is realized.
本发明公开了一种平台化后副车架结构,后副车架中部呈中空的框形结构,且由前横梁、后横梁、左纵梁和右纵梁焊接相连而成,后副车架框形结构内设有至少两个加强件;两个加强件的一端均焊接在前横梁上,另一端分别焊接在左纵梁、右纵梁上,使得加强件在后副车架上围成两个三角状空间。采用本发明,通过加强件使得后副车架上形成两个三角状空间,三角形的结构稳固,保证了后副车架有较高的强度、NVH、操稳性能;此外加强件仅位于后副车架的两个角落,后副车架的中部位置留有足够大的空间,可满足多型号驱动电机的空间需求,增强了后副车架的通用性;电机安装支架及后横梁孔洞的多功能性,满足了不同动力配置需求,实现了后副车架的平台化。
