The invention relates to the technical field of large cross-country vehicle manufacturing, in particular to a variable cross-section large-tonnage transfer vehicle frame and a vehicle. The invention provides a variable cross-section large-tonnage transfer vehicle frame which comprises a first longitudinal beam and a second longitudinal beam, the first longitudinal beam and the second longitudinal beam are symmetrically arranged to form a frame body, the frame body comprises a first cross beam mounting part, a variable cross-section transition part, an equipment mounting part and a second cross beam mounting part, and the variable cross-section transition part comprises a transition frame. The transition frames are arranged on the first longitudinal beam and the second longitudinal beam respectively, and the height of one end, close to the equipment mounting part, of each transition frame is larger than that of the other opposite end; the second cross beam mounting part comprises a third suspension cross beam and a vehicle tail cross beam, and the third suspension cross beam is arranged between the tail end of the equipment mounting part and the vehicle tail cross beam. According to the technical scheme, the internal arrangement space of the frame is maximized, the overall arrangement difficulty is reduced, the strength and rigidity are good, and the space avoiding requirement and the overweight bearing requirement of hoisting equipment are met.

    本公开涉及大型越野车辆制造技术领域,尤其涉及一种变截面大吨位转载车车架及车辆。本公开提供了一种变截面大吨位转载车车架,包括第一纵梁和第二纵梁,第一纵梁和第二纵梁对称设置构成车架本体,车架本体包括第一横梁安装部、变截面过度过渡部、设备安装部和第二横梁安装部,变截面过渡部包括过渡车架,过渡车架分别设置在第一纵梁和第二纵梁上,且过渡车架靠近设备安装部一端的高度大于相对的另一端的高度;第二横梁安装部包括第三悬架横梁和车尾横梁,第三悬架横梁设置在设备安装部的尾端与车尾横梁之间。通过实施本公开的技术方案,实现车架内部布置空间最大化,降低总体布置难度,且具有较好的强度和刚度,满足吊装设备空间避让要求和超重承载要求。
