Abstract

The invention belongs to the technical field of aluminum alloy welding, and relates to an automobile power bearing device. The automobile power bearing device is formed by welding thirteen frames which are located at the outermost side, three parallel upper water cooling plates, three parallel lower water cooling plates, three parallel supporting beams, one bottom plate and fourteen mounting supports located at the bottom of the power bearing device; and the upper water cooling plates and the lower water cooling plates are symmetrically installed on the upper side of the bottom plate and the lower side of the bottom plate correspondingly. The welding process comprises the steps of frame welding, upper water cooling plate welding, welding between the supporting beams and the frames, weldingbetween the bottom plate and the frames, welding between the lower water cooling plates and the bottom plate and welding between the mounting supports and the frames. The problem that in the prior art, a new energy automobile power bearing part adopts a steel plate structure, and the self weight is large, so that energy conservation and emission reduction of the automobile are not facilitated issolved.

Description

technical field [0001] The invention belongs to the technical field of aluminum alloy welding, and relates to a welding process for a power bearing device of an aluminum alloy new energy vehicle. Background technique [0002] Aluminum is one of the most abundant elements in the earth's crust, with a content of 8.8%, ranking first among the four major metal elements and accounting for 1 / 3 of the total mass of metal elements. Due to the improvement of aluminum technology, the aluminum industry is developing at an astonishing speed. By 2004, the world's aluminum output reached 29.8 million tons, of which my country's output was 6.8 million tons, ranking third in the world, and there were more than a thousand kinds of aluminum alloys. Due to the development of aluminum materials, the processing technology of aluminum has also been advanced by leaps and bounds. Due to its light weight, high specific strength, good low temperature performance, good plasticity, easy processing an...
