Problems solved by technology

As a result, the structures in the prior art (including the steel-aluminum mixed sub-frame structure in the prior art) are limited in platform and modular applications. Vehicles with the same platform often need to adjust the lateral dimension of the sub-frame in order to adjust the wheelbase. The cost of the middle beam mold is the highest. Once the size is adjusted, the mold needs to be redeveloped, which cannot flexibly meet the platform requirements

Embodiment 1

[0024] Such as Figure 2-6 As shown, the modularized steel-aluminum hybrid subframe structure of this embodiment includes four parts: a left beam module 100 , a right beam module 200 , a cross beam module 300 and a reinforcing bracket 400 . The beam module 300 is a hollow beam structure formed by welding an upper plate 3100 with a flange and a lower plate 3200 with a flange at the flange, and the upper plate and the lower plate of the beam module can be punched according to circumstances There are several lightening holes, and the upper plate and the lower plate are stamped from high-strength steel plates. The left end and the right end of the beam module 300 are respectively provided with at least two mounting holes 3170 passing through the upper plate and the lower plate, and the matching surfaces with the left beam module are 3171 and 3172; the left beam module 100 and the right beam module 200 It is a left-right symmetrical structure, the left beam module and the right be...

Abstract

The invention relates to a modularized steel-aluminum mixed auxiliary automobile frame structure and belongs to the technical field of automobile design and manufacture. The modularized steel-aluminummixed auxiliary automobile frame structure comprises a left edge beam module, a right edge beam module, a cross beam module and a reinforcing support module. In order to meet the requirements for theleft and right installation spans of different auxiliary automobile frames, a main module is universal, only the length of a middle cross beam is changed, the middle cross beam can be of a sectionalmaterial or metal plate stamping and welding structure, a main mold is not changed, a reinforcing support can be spliced and welded through steel profiles and aluminum profiles or steel pipes and aluminum pipes according to strength requirements, only the size of a welding fixture is adjusted, the change cost is quite low, the above auxiliary automobile frames are modularized through a bolt connection thought, the universality rate of parts between platform automobile models is increased, and development cost is reduced.

Description

technical field [0001] The invention relates to the technical field of automobile design and manufacture, and more specifically, the invention relates to a modular steel-aluminum mixed sub-frame structure. Background technique [0002] figure 1 It shows the common front subframe structure (yuanbao beam, butterfly subframe) of A0 and A class passenger cars in the prior art. The main body of the subframe is I-shaped when viewed from above, and the upper and lower plates are fastened and welded , forming a large cavity, the front curved arm adopts a pipe or sheet metal snap-fit ​​welding structure, which is inserted into the welding main body of the sub-frame and welded to the upper and lower plates respectively. In order to reduce the weight, the prior art has developed a connection structure comprising a subframe body made of aluminum and a steel material, or a connection structure between a subframe body made of steel and an aluminum material. From a heavy point of view, t...
