Stabilizer Link Reinforcement Parts Embedded in Housing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing stabilizer link design fails to effectively reinforce the periphery of the ball part while maintaining a reduced external size, leading to increased size for enhanced rigidity, which limits its compactness and efficiency.
Innovation Solution
A stabilizer link with a metal support bar featuring reinforcement parts of nearly annular shape embedded in the resin housing to surround the ball part, combined with a U-shaped or L-shaped cross section for enhanced strength, and a manufacturing process involving press-forming and punching to form the support bar and reinforcement parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the support bar end parts are made simple without surrounding the ball part, then the manufacturing process is simpler, but the tensile breaking strength of the ball part periphery is insufficient
Solution Approach 1:
The support bar is segmented into a body part and separate reinforcement parts. The reinforcement parts are formed by folding the end parts of the support bar to create annular structures that surround the ball part, providing enhanced tensile breaking strength without complicating the overall manufacturing process
Solution Approach 2:
The reinforcement parts extend in the radial direction from the body part to surround the ball part. This dimensional extension creates an annular structure that provides tensile breaking strength in multiple directions while maintaining a compact design
2Strength
If the housing size is increased to enhance section rigidity, then the tensile breaking strength is improved, but the external size of the stabilizer link increases
Solution Approach 1:
Instead of uniformly increasing the housing size, the reinforcement parts are strategically positioned only where needed - at the end parts of the support bar surrounding the ball part. This localized reinforcement provides enhanced section rigidity exactly where the tensile breaking strength is required, without increasing the overall external size of the stabilizer link
3Strength
If the reinforcement parts are embedded in the housing to surround the ball part, then the tensile breaking strength is enhanced, but the manufacturing precision requirements increase
Solution Approach 1:
The reinforcement parts are formed by folding the end parts of the support bar during the manufacturing process itself, rather than being separate components requiring post-assembly. This preliminary formation ensures proper positioning and embedding of the reinforcement parts in the housing, reducing manufacturing precision requirements for separate assembly operations
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design achieves both enhanced tensile breaking strength and reduced external size, ensuring effective coupling of the suspension device and stabilizer while preventing interference and maintaining mobility.
Implementation Method 1

AI summary
This stabilizer link includes a metal support bar, and ball joints that are provided at both ends of the support bar. Each ball joint includes a ball stud one end of which is fastened to a suspension device or a stabilizer, and which has a ball part at the other end thereof, and a housing that rotatably supports the ball part of the ball stud. The support bar includes: a body part extending in a nearly linear shape, and reinforcement parts each having a nearly annular shape and each provided at both ends of the body part. The reinforcement parts of the support bar are each embedded in the housing so as to surround the ball part.
