Assembly type aluminum alloy gooseneck frame sub-assembly

The invention relates to the technical field of vehicle frames, in particular to an assembly type aluminum alloy gooseneck vehicle frame sub-assembly which comprises gooseneck longitudinal beams, gooseneck transverse beams, a front end beam and a traction assembly. The gooseneck longitudinal beam, the gooseneck cross beam, the front end beam and the traction assembly are fixedly connected throughbolts or rivets; the gooseneck longitudinal beam is a square-tube-shaped aluminum alloy section bar with a cavity, and the gooseneck cross beam is a groove-shaped aluminum alloy section bar. The gooseneck vehicle frame sub-assembly has the beneficial effects that the gooseneck vehicle frame sub-assembly is designed in a subassembly mode, all parts are connected through bolts or rivets in an assembled mode, the technological requirements for deformation control, correction and the like are avoided, the production efficiency is improved, and meanwhile all the parts are easy to maintain and replace; the gooseneck longitu
