Problems solved by technology

The sub-frame of traditional models is basically made of steel stamping and welding parts, which has the disadvantages of many stamping parts, many welding processes, and heavy weight. Torque loss, bushing installation abnormal sound and other quality problems affect the vehicle performance adjustment
[0003] With the requirements of energy saving and emission reduction in modern society and the requirements of national environmental protection policies, new energy vehicles are gradually popularized. It needs to have good lightweight design requirements to meet the quality target of the vehicle and increase the cruising range of the vehicle. If the existing steel subframe is used in new energy vehicles, the quality is heavy and the accuracy is not easy to guarantee, and it will affect the whole vehicle. The vehicle quality target is achieved, and the cruising range of the vehicle is reduced

Abstract

The invention relates to an aluminum alloy auxiliary frame which comprises an auxiliary frame body, the auxiliary frame body is integrally formed and manufactured by adopting a high-performance aluminum alloy material, a plurality of reinforcing ribs are arranged on the auxiliary frame body, the reinforcing ribs are radially distributed on the auxiliary frame body, and a plurality of lightening holes are formed in the auxiliary frame body. The aluminum alloy structure is adopted, under the condition that the overall strength and rigidity of the auxiliary frame are guaranteed, the weight of the auxiliary frame is greatly reduced, and the requirement for light weight of a vehicle is met.

Description

technical field [0001] The invention relates to the field of automobile subframes, in particular to an aluminum alloy subframe. Background technique [0002] The subframe is the skeleton of the front and rear axles of the car, which integrates the suspension swing arm mechanism and is an important part of the car suspension. The subframe of the traditional model is basically a steel stamping and welding part, which has many disadvantages such as many stamping parts, many welding processes, and heavy weight. Each installation point is a stamping and welding structure, so the dimensional accuracy is not easy to control, and it is easy to produce fasteners. Torque loss, abnormal noise of bushing installation and other quality problems affect the performance adjustment of the whole vehicle. [0003] With the requirements of energy conservation and emission reduction in modern society and the requirements of national environmental protection policies, new energy vehicles are gra...
