General type aluminum alloy automobile sub-frame structure

Abstract

The invention relates to a general type aluminum alloy automobile sub-frame structure. The general type aluminum alloy automobile sub-frame structure comprises an aluminum sub-frame crossbeam and end part aluminum castings, wherein the aluminum sub-frame crossbeam is in the shape of a bended arch; the end part aluminum castings are separately and symmetrically connected to two ends of the aluminum sub-frame crossbeam; upper swinging arm connecting seats are arranged on the upper end surface of each end part aluminum casting side by side; a lower swinging arm connecting seat and an oblique pull rod connecting seat are arranged at the lower end surface of each end part aluminum casting; each upper swinging arm connecting seat, each lower swinging arm connecting seat and each oblique pull rod connecting seat are separately formed by two punched vertical plates which are arranged side by side; a U-shaped clamping plate is in sleeving connection to each punched vertical plate to cover two side walls of the corresponding punched vertical plate; and an exhaust pipe lifting hook is also mounted on the aluminum sub-frame crossbeam. According to the general type aluminum alloy automobile sub-frame structure disclosed by the invention, the problem that under the premise that relevant surrounding pieces of a sub-frame are not changed, when a conventional iron sub-frame is switched into the aluminum sub-frame, the changes of the strength and the rigidity between iron materials and aluminum materials are great can be solved; the total weight of an automobile chassis system is reduced; and lightweighting is realized.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a general-purpose aluminum alloy automobile sub-frame structure. Background technique [0002] 60% of all energy consumption of a car comes from its own weight, and every 10% reduction in vehicle weight can reduce fuel consumption by 10% to 15%. Among them, the chassis system is an important part of the car. The weight of the chassis system accounts for more than 30% of the total weight of the car. The lightweight of the chassis system can not only reduce fuel consumption, but also has an important impact on the comfort of the vehicle. [0003] In the existing market, traditional automobile sub-frames are all made of steel substrates, and the sub-frame is made of steel. Although the cost is low, the overall body is bulky, with many components and complicated processes, which is not conducive to energy saving and emission reduction. So now some chassis systems on the market are made of ...
