The invention relates to the technical field of vehicle engineering, in particular to a vehicle body side wall and a truck, the vehicle body side wall comprises a longitudinal beam assembly, a door frame skeleton, a container skeleton and a reinforcing piece, and the longitudinal beam assembly comprises a longitudinal beam front section, a longitudinal beam middle section and a longitudinal beam rear section; the door frame skeleton is annular and is fixed on the middle section of the longitudinal beam; the container framework is fixed to the longitudinal beam rear section and fixed to the door frame framework, and the container framework and the longitudinal beam rear section form a first annular structure. The front end of the reinforcing piece is fixed with the front section of the longitudinal beam, and the rear end of the reinforcing piece obliquely extends upwards and backwards and is fixed with the middle of the front end of the door frame skeleton; the reinforcing piece, the longitudinal beam front section and the door frame framework form a second annular structure, the second annular structure, the door frame framework and the first annular structure form three annular force transmission structures which are sequentially fixed from front to back, and the overall bearing capacity and impact resistance of the vehicle body are enhanced.
本发明涉及车辆工程技术领域,特别是涉及一种车身侧围及货车,车身侧围包括纵梁总成、门框骨架、货箱骨架和增强件,纵梁总成包括从纵梁前段、纵梁中段和纵梁后段;门框骨架呈环状且固定在纵梁中段上;货箱骨架固定在纵梁后段上且与门框骨架固定,货箱骨架与纵梁后段形成第一环状结构;增强件的前端与纵梁前段固定,增强件的后端向上、向后倾斜延伸并与门框骨架前端中部固定;增强件与纵梁前段和门框骨架形成第二环状结构,第二环状结构、门框骨架以及第一环状结构构成从前至后依次固定的三个环状传力结构,增强了车身的整体承载能力和抗冲击性。
