Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a non-circular bushing with strong connection. Background Technology

[0002] As people's living standards improve, they are paying increasing attention to the comfort of vehicles. Bushings play a crucial role in automotive systems such as suspension and steering, reducing friction between components, absorbing vibrations, and ensuring proper component positioning. However, with the automotive industry's ever-increasing demands for comfort and reliability, traditional automotive bushings are gradually revealing some problems. During driving, when subjected to various external forces such as road bumps and steering forces, bushings are prone to loosening and wear, affecting the vehicle's handling and stability. Furthermore, in terms of ride comfort, traditional bushings cannot effectively filter high-frequency vibrations, resulting in noticeable vibrations and noise inside the vehicle, thus reducing the driving experience. Therefore, developing an automotive bushing that achieves strong connection and excellent comfort is urgently needed. Utility Model Content
