AI Technical Summary

⚠Technical Problem

Existing car wheel hubs are prone to breakage under special circumstances and have poor functionality, especially when subjected to lateral force, stress concentration leads to instability in the local support structure.

⚗Method used

A high-compression-resistant automotive steel wheel hub was designed, featuring streamlined spokes and a multi-step structure. One end of the spoke is welded to the side wall of the central disc, while the other end is fastened to the multi-step structure and welded in place. A support column is provided in the middle of the spoke to distribute stress and enhance toughness and stability.

🎯Benefits of technology

It improves the compressive strength of the wheel hub, disperses stress by supporting columns to prevent breakage, and enhances the overall stability and compressive strength of the wheel hub.

Abstract

This utility model discloses a high-compression-resistant steel automotive wheel hub, comprising a rim, spokes, and a center disc from the outside in. The rim has a ring structure with symmetrical inner and outer sides. The edge of the rim has a multi-step structure. One end of the spoke is welded to the side wall of the center disc, and the other end of the spoke is engaged with and welded to the multi-step structure. The spokes have a streamlined structure with supporting columns protruding to both sides in the middle. In this application, by casting the steel spokes into a streamlined structure, a certain yield strength is increased, giving it a certain degree of toughness. Under stress, the supporting columns in the middle provide the main support, while the outer parts disperse stress, resulting in more balanced compressive strength. Even when subjected to lateral stress, energy absorption and release can prevent breakage.
