AI Technical Summary

Technical Problem

The existing suspension system of new energy vehicles has problems such as insufficient rigidity, increased weight and insufficient adaptability of the front subframe, which affects the handling accuracy and safety, especially under extreme driving or complex road conditions.

Method used

Design a front subframe structure for a new energy vehicle suspension system. The front crossbeam, left longitudinal beam, right longitudinal beam, and rear crossbeam are all made of round tubes and are connected by welding and bolts to form an integrated U-shaped structure. This structure connects the vehicle body to the suspension system control arm and supports the steering system. Sheet metal brackets are used to improve connection strength and reduce weight.

Benefits of technology

A front subframe of the suspension system with simple structure, light weight and low cost has been achieved, which improves the overall rigidity and torsional resistance, and meets the lightweight and safety requirements of new energy vehicles.
