Abstract

The invention relates to a steel-aluminum mixed type front auxiliary frame structure, which belongs to the technical field of automobile chassis auxiliary frames, and comprises a left aluminum alloy support, a right aluminum alloy support, a left aluminum pipe beam, a right aluminum pipe beam and a right aluminum alloy support, the two ends of the left aluminum pipe beam are respectively welded with the left front aluminum alloy support and the left rear aluminum alloy support into a whole; the right aluminum alloy support comprises a right front aluminum alloy support, a right aluminum pipe beam and a right rear aluminum alloy support which are sequentially connected from front to back, and the two ends of the right aluminum pipe beam are welded to the right front aluminum alloy support and the right rear aluminum alloy support into a whole respectively; the middle connecting support comprises a front aluminum alloy cross beam and a steel welding support which are fixedly connected between the left aluminum alloy support and the right aluminum alloy support, and the steel welding support is located behind the front aluminum alloy cross beam. The steel-aluminum mixed structure is adopted, the structure is simple, the weight is light, the rusting risk is avoided, the quality of the automobile chassis is improved, and the fuel economy and the endurance mileage of an automobile are improved.

Description

technical field [0001] The present application relates to the technical field of automobile chassis sub-frames, in particular to a steel-aluminum mixed front sub-frame structure. Background technique [0002] The sub-frame of an automobile is a bracket that supports the front and rear axles and suspensions, so that the axles and suspensions are connected to the body through it. effect of noise. The sub-frame of an automobile is a very important component, which has high requirements on the body structure of the area where it is attached, so the structure of the car body connected to the sub-frame and the surrounding load-bearing parts. [0003] The existing rear subframe is usually an iron subframe, which is heavy in weight, rigidity, and mode cannot meet the actual needs, there are many stamping parts, some parts are difficult to form, the welding process is complicated, the design of the welding fixture is complicated, and the welding deformation Large, poor assembly siz...
