AI Technical Summary

Technical Problem

When improving local modal and fatigue performance, existing gooseneck cast aluminum steering knuckles often require traditional reinforcement methods that result in increased overall weight or complex structural modifications, making it difficult to achieve lightweighting and platform versatility.

Method used

A carbon fiber reinforcing layer is prepared by forming an interface reinforcement structure on the outer surface of the aluminum alloy steering knuckle body and coating it with KH-560 modified nano silica prepreg. The interface connection is synergistically enhanced through mechanical anchoring and chemical bonding.

Benefits of technology

Without increasing the overall weight, the performance of the weakest part of the steering knuckle and the platform adaptability are significantly improved, achieving a balance between lightweight and high strength.

Abstract

本申请提供了一种转向节制备工艺和一种转向节。该转向节制备工艺包括:在铝合金转向节主体的外表面形成具有机械锚定作用的界面增强结构;制备包含KH‑560改性纳米二氧化硅的碳纤维预浸料;将所述碳纤维预浸料包覆在所述转向节主体的外表面;对包覆的预浸料进行固化处理,以在转向节主体外表面形成碳纤维加强层。该方案通过在转向节表面包覆碳纤维加强层,实现转向节在保证结构强度的前提下显著减重;同时,从宏观机械锚定和微观化学粘接两个维度协同增强界面结合,进而在保证满足轻量化需求的同时,有效提高转向节的结构强度。
