Embodiment Construction

[0021] The present invention will be described below in conjunction with the accompanying drawings and specific embodiments.

[0022] see figure 1 , a rear axle of a magnesium alloy car in the present invention includes three parts: a front connection welding assembly 1 , a swing arm support box body welding assembly 2 , and a rear connection welding assembly 3 . The three assemblies are welded to each other and positioned according to four elastic supports.

[0023] see figure 2 , Front connection welding assembly 1 is made up of right front cover 101, left front cover 102, left front support plate 103, right front support plate 104, elastic bushing 105. Connect the left and right front support plates to each other first, then weld the left and right front covers 102, 101 on the front support plates 103, 104 respectively, and then install the elastic bushing 105. Process holes are arranged on the left and right front covers 102, 101, which are convenient for installing th...

Abstract

The invention relates to an automotive part, in particular to a light automotive rear axle, which comprises a front connected and welded assembly, a swing arm supporting box body welded assembly and a rear connected and welded assembly, all of which are made of magnesium alloy materials. The whole rear axle adopts a basically symmetrical structure; the front connected and welded assembly is formed by welding an elastic lining, left and right front supporting plates and left and right front covers; the swing arm supporting box body welded assembly consists of a box body, an insert piece, a bottom plate and a partition plate, and the box body is provided with bolt holes which are used for connecting the two lateral swing arms of a rear suspension system; and the rear connected and welded assembly comprises an elastic lining, left and right cross stabilizing rod supports, left and right rear arms and upper and lower covers. The static performance and dynamic performance of the automotive rear axle of the invention meet service requirements, and the design of introducing the magnesium alloy material into the automotive rear axle has a great significance for improving automotive lightweight technical level and promoting the development of the magnesium alloy industry in China.

Description

technical field [0001] The invention relates to an automobile part, in particular to a lightweight car rear axle. Background technique [0002] At present, with the continuous improvement of people's living standards, the demand for cars is also increasing. The annual output of major automobile companies is on the rise year by year. At the same time, oil resources around the world are becoming increasingly tense, and oil prices are constantly rising. Environmental pollution and energy shortage will become important issues restricting the sustainable development of my country's automobile industry. Regardless of economic or social benefits, low-fuel consumption and low-emission vehicles will be the needs of the development of a conservation-oriented society. Carrying out lightweight design on automobiles and reducing the weight of automobiles is the key to solving the above problems and maintaining the sustainable and healthy development of the automobile industry. There a...
