Abstract

The invention discloses an automotive front auxiliary frame structure. The automotive front auxiliary frame structure comprises a front auxiliary frame upper plate (1) and a front auxiliary frame lower plate (2), and flanges as reinforcing structures are respectively arranged on the front auxiliary frame upper plate (1) and the front auxiliary frame lower plate (2) and are connected with each other by seam welding. By the technical scheme, the automotive front auxiliary frame structure is simple, scientific and reasonable in overall layout, convenient to manufacture and simple in machining technology, and the production cost is greatly reduced; based on lightweight design thinking, the use amount of materials is reduced, and the manufacturing cost of the automotive front auxiliary frame is reduced effectively; the weight of an automobile body is reduced, and fuel economy of a whole automobile is improved; the reinforcing structures such as bosses and the flanges are arranged, stress concentration at positions where the front auxiliary frame is connected with a swing arm, a stabilizing rod and the like is reduced, so that risks of fatigue cracking of the front auxiliary frame are greatly reduced, requirements of strength and rigidity are met, meanwhile, the structure is simplified, and safety and stability of the front part of the automobile are improved.

Description

technical field [0001] The invention belongs to the technical field of automobile structure, and relates to an automobile body structure, and more specifically, relates to an automobile front auxiliary frame structure.
