The invention discloses a light-weight heavy-duty truck frame which comprises two longitudinal beams, the two longitudinal beams are arranged in parallel, and a C-shaped reinforcing plate, a first L-shaped reinforcing plate, a second L-shaped reinforcing plate and an airplane beam reinforcing plate are installed on each longitudinal beam. A first tubular cross beam, a groove-shaped cross beam, a second tubular cross beam, a third tubular cross beam, an airplane beam, a fourth tubular cross beam and a tail beam are sequentially installed between the two longitudinal beams from left to right, tower connection reinforcing plates are installed at the two ends of the first tubular cross beam, the two ends of the second tubular cross beam and the two ends of the third tubular cross beam, and the tower connection reinforcing plates are installed on the longitudinal beams. According to the device, the whole reinforcing beam penetrating from front to back is omitted, the number of the cross beams is reduced, the distance between the cross beams is increased, a light tail beam is replaced, and the mass of the frame is reduced; the tubular cross beams replace groove-shaped cross beams, so that the stress is not concentrated at one point when the frame is twisted, the overall torsion resistance of the frame is improved, the number of the mounting cross beams of the frame is allowed to be reduced, and the quality of the frame is reduced.

    本发明公开了一种轻量化重型载货车车架,包括两个纵梁,所述两个纵梁平行设置,在两个纵梁上都安装有C型加强板、第一L型加强板、第二L型加强板以及飞机梁加强板,在两个纵梁之间从左到右依次安装有第一管状横梁、槽型横梁、第二管状横梁、第三管状横梁、飞机梁、第四管状横梁以及尾梁,所述第一管状横梁、第二管状横梁以及第三管状横梁的两端都安装有塔接加强板,所述塔接加强板安装在纵梁上。本发明该装置通过取消从前到后贯通的整体加强梁,减小横梁数量,增加横梁间距,更换轻量化尾梁,实现车架质量的降低;管状横梁替换槽型横梁,使车架受扭时应力不集中于一点,增加车架整体抗扭性能,允许车架减少安装横梁的数量,实现车架的质量降低。
