Abstract

The invention discloses a novel aluminum alloy auxiliary frame which comprises a front cross beam, a rear cross beam, a left longitudinal beam and a right longitudinal beam, and the front cross beam, the rear cross beam, the left longitudinal beam and the right longitudinal beam are all of a hollow tubular structure formed by extrusion forming of aluminum alloy sections. The auxiliary frame further comprises a left front mounting bracket, a right front mounting bracket, a left rear mounting bracket and a right rear mounting bracket; the left front mounting bracket, the right front mounting bracket, the left rear mounting bracket and the right rear mounting bracket are all formed by casting aluminum alloy. According to the novel aluminum alloy auxiliary frame, through the front cross beam, the rear cross beam, the left longitudinal beam and the right longitudinal beam which are formed through extrusion, the weight is light, the yield is high, the cost is low, and welding is easy to control; the left front mounting bracket, the right front mounting bracket, the left rear mounting bracket and the right rear mounting bracket need to be connected with other parts of a vehicle body or a chassis, structural changes are complex, and the mechanical performance of casting parts formed through casting is improved.

Description

technical field [0001] The invention relates to the field of automobile manufacturing, in particular to a novel aluminum alloy auxiliary frame. Background technique [0002] At present, the global automobile production and ownership are increasing, and the safety requirements for automobiles are also getting higher and higher. The sub-frame is an important part of the current mainstream car chassis. The structural form, stiffness and strength of the sub-frame have a great impact on the durability, comfort and handling of the vehicle. It is an important basis for measuring the design level of the car chassis. Therefore, the research on the structure design and optimization technology of the sub-frame of the automobile has attracted much attention. At present, the subframe is mainly made of steel stamped and welded subframe, and the connection structure of the steel stamped and welded subframe is generally in the form of stamped and welded brackets, which are connected to the...
