Abstract

The invention discloses a lightweight structure of a subframe, which comprises a subframe body, wherein the subframe body is provided with a weight reducing hole; the lightweight structure further comprises a cross reinforcing rib structure for connecting mounting points on the subframe body to form an integral structure; and the cross reinforcing rib structure is arranged on the subframe body. The whole subframe of the invention is butterfly-shaped, and the main body is designed in the form of box-shaped cross-grid reinforcing ribs, so that the rigidity and strength of the subframe are increased and the mode of the subframe is lifted at the same time. Multiple irregular hollowed-out weight loss design to minimize weight loss.

Description

technical field [0001] The invention belongs to the technical field of auto parts, and in particular relates to a lightweight structure of an auxiliary frame. Background technique [0002] In recent years, energy and environmental issues have become the focus of human attention. Under the background of increasing energy shortage and increasingly serious environmental pollution, reducing vehicle weight to achieve energy conservation and emission reduction has become an important task for automobile companies. Among them, the subframe is an important part of the automobile, and its weight and performance are increasingly valued by various vehicle manufacturers. The stamping and welding deformation of the traditional subframe is not easy to control. How to meet the performance requirements in the limited layout space of the vehicle, It can also achieve the goal of reducing weight and has high precision, which has become a key breakthrough point in the lightweight design of the ...
