The invention provides a novel equal-width straight-through light truck frame which comprises a left longitudinal beam, a right longitudinal beam and seven cross beam assemblies arranged between the left longitudinal beam and the right longitudinal beam, and the left longitudinal beam and the right longitudinal beam are single-layer beams and are of an equal-stress front-back variable cross-section universal structure. The seven cross beam assemblies are sequentially arranged in the length direction of the longitudinal beam and include the head cross beam assembly, the tubular beam assembly, the third cross beam assembly, the fourth cross beam assembly, the fifth cross beam assembly, the sixth cross beam assembly and the tail cross beam assembly. The head cross beam assembly, the third cross beam assembly, the fourth cross beam assembly, the fifth cross beam assembly, the sixth cross beam assembly and the tail cross beam assembly each comprise a C-shaped cross beam. The overall mass of the frame is reduced from the aspect of structural optimization, and the requirements for frame performance and overall arrangement of the whole vehicle can be met.
本申请提供一种新型等宽直通轻卡车架,包括左纵梁、右纵梁以及设置于所述左纵梁与右纵梁之间的七根横梁总成,所述左纵梁与右纵梁为单层梁且采用等应力前后变截面通用化结构,所述七根横梁总成沿纵梁长度方向依次排列且分别为首横梁总成、管梁总成、第三横梁总成、第四横梁总成、第五横梁总成、第六横梁总成以及尾横梁总成,所述首横梁总成、第三横梁总成、第四横梁总成、第五横梁总成、第六横梁总成以及尾横梁总成均包括C型横梁。从结构优化方面降低了车架整体质量,能够满足车架性能及整车总布置要求。
