The invention discloses a non-bearing frame longitudinal beam. The longitudinal beam comprises a C-shaped longitudinal beam body (1), and also comprises at least two right square pyramid frames (2) which are arranged on the inner side of the C-shaped longitudinal beam body (1) and are arranged along the axis of the C-shaped longitudinal beam body (1) at equal intervals, two fixedly connected tetrahedron frames (3) are arranged between every two adjacent right square pyramid frames (2), and the two ends of the two connected tetrahedron frames (3) are fixedly connected with the two right squarepyramid frames (2) respectively. The non-bearing frame longitudinal beam is good in collision resistance and light in weight.

    本发明公开一种非承载式车架纵梁,包括匚型纵梁本体(1),还包括设于所述匚型纵梁本体(1)内侧、沿所述匚型纵梁本体(1)轴线等间距设置的至少两个正四棱锥框架(2),相邻两个正四棱锥框架(2)间设有两个固定相连的四面体框架(3),所述两个相连的四面体框架(3)两端分别与所述两个正四棱锥框架(2)固定连接。本发明的非承载式车架纵梁,耐撞性能好、重量轻。
