The invention discloses an aluminum alloy vehicle body framework which comprises a vehicle body base frame, the vehicle body base frame comprises a plurality of bearing main frames, the bearing main frames are arranged in the length direction of a vehicle body, the plurality of bearing main frames are arranged in parallel, and the plurality of bearing main frames are sequentially provided with a plurality of positioning mounting frames from one end to the other end; the plurality of bearing main frames are fixedly connected through the plurality of positioning mounting frames; the multiple bearing main frames and the multiple positioning mounting frames form a vehicle body, and the front wheel frames, the second treading frames and the rear wheel frames are sequentially arranged on the two sides of the vehicle body from the front end to the rear end. According to the aluminum alloy vehicle body framework, through the cooperative design of multiple structures, the overall structural strength of the vehicle body framework is effectively guaranteed, the overall structure is stable and firm, the structure is compact, aluminum alloy materials are used for replacing steel to serve as manufacturing materials of the middle bus body framework and covering parts, and the manufacturing cost is reduced. And the self weight of the vehicle body is greatly reduced on the premise of ensuring the rigidity and the strength.

    本发明公开了一种铝合金车身骨架,包括:车体基架,车体基架包括承载主架,承载主架沿车身长度方向设置,承载主架的数量为多个,多个承载主架平行设置,多个承载主架从一端至另一端依次设置有多个定位安装架,多个承载主架通过多个定位安装架固定连接;多个承载主架和多个定位安装架组成车身主体,车身主体的两侧从前端至后端依次设置有前轮架、第二踩踏架、后轮架。本发明提供的一种铝合金车身骨架,通过多结构的配合设计,有效确保车身骨架的整体结构强度,且整体结构较为稳定牢固,结构紧凑,通过利用铝合金材料代替钢材作为中巴身骨架和覆盖件的制作材料,使得车身在保证刚度和强度的前提下自重得到较大幅度降低。
