The invention discloses a multi-axle off-road vehicle frame structure with a variable axle distance. The multi-axle off-road vehicle frame structure comprises a front bumper, a vehicle body front suspension beam, a front axle structure, a cross beam, longitudinal beams, a vehicle body rear suspension beam, a container supporting structure, a middle axle structure, a rear axle structure and a rearbumper. The two longitudinal beams are oppositely arranged in the left-right direction of a vehicle body and comprise the left longitudinal beam and the right longitudinal beam; each longitudinal beamis a box beam formed by tailor-welding two first channel beams along the left-right direction of the vehicle body; an engine mounting hole, a transmission mounting hole and a suspension mounting holeare formed in each longitudinal beam; each longitudinal beam comprises a vehicle front section, a vehicle middle section and a vehicle rear section which are integrally formed; each vehicle front section and each vehicle rear section are higher than the corresponding vehicle middle section, so that the longitudinal beams are arranged in the front-back direction of the vehicle body with two high ends and a low middle. According to the invention, the distance between the vehicle body front suspension and the vehicle body rear suspension can be adjusted to meet the requirements of vehicle bodieswith different lengths; and the distance among the front axle structure, the middle axle structure and the rear axle structure can be adjusted to adapt to different chassis arrangements and the performance requirements of the whole vehicle.

    本发明公开了一种轴距可变的多轴越野车车架结构,包括:前保险杠、车身前悬置梁、前轴结构、横梁、纵梁、车身后悬置梁、货箱支撑结构、中轴结构、后轴结构和后保险杠;两个纵梁沿车身左右方向相对设置,两个纵梁包括左纵梁和右纵梁;纵梁为由两片第一槽型梁沿车身左右方向拼焊形成的箱型梁;纵梁开设有发动机安装孔、变速器安装孔、悬架安装孔;纵梁包括一体成型的车前段、车中段和车后段;车前段和车后段均高于车中段设置,使纵梁沿车身前后方向呈两端高中间低布置。本发明不仅能实现车身前悬置和车身后悬置的间距调整以适用不同长度的车身需求;还可实现前轴结构、中轴结构和后轴结构之间的间距调整以适用不同的底盘布置和整车性能需求。
