The invention relates to the technical field of all-terrain vehicle design, in particular to a multi-axle unmanned all-terrain vehicle frame. Comprising an upper frame, a bottom frame, a front frame, a rear frame, a front support frame, a middle support frame and a rear support frame, the upper frame comprises two upper longitudinal beams and four upper cross beams, and upper reinforcing ribs are arranged at the joints of the upper longitudinal beams and the upper cross beams; the bottom frame comprises three bottom longitudinal beams, four side beams and six bottom cross beams, and bottom reinforcing ribs are arranged at the joints of the bottom longitudinal beams, the side beams and the bottom cross beams; according to the structural form that the frame is wide in upper portion and narrow in lower portion and locally protrudes, the problem that the overall dimension or appearance modeling of the whole vehicle does not meet the requirement due to the fact that the size of an engine is large is solved, the frame type frame structure reduces the weight of the whole vehicle, improves the heat dissipation performance of the whole vehicle, is convenient to overhaul, and meanwhile can meet the using requirements of transportation, loading and serialization expansion.
本发明涉及全地形车辆设计技术领域,具体涉及一种多轴无人全地形车车架;包括上车架、底车架、前车架、后车架、前支撑架、中支撑架和后支撑架;上车架包括两个上纵梁和四个上横梁,且上纵梁和上横梁的连接处均设置有上加强筋;底车架包括三个底纵梁、四个边梁和六个底横梁,且底纵梁、边梁和底横梁的连接处均设置有底加强筋;本设计的车架上宽下窄、局部凸出的结构形式,解决了因发动机尺寸较大导致整车外形尺寸或外观造型不符合要求的问题,框架式车架结构,减轻了整车重量,提高了整车散热性和便于检修,同时能满足运输、上装和系列化拓展使用需求。
