Strut Suspension Layout to Reduce Steering Friction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional strut suspension systems face challenges in reducing steering frictional resistance and maintaining control stability while simplifying the mechanical structure and reducing manufacturing costs, particularly in independent suspension systems where the integration of stabilizer bars and links increases complexity and cost.
Innovation Solution
A strut suspension system with a stabilizer link integrally coupled to a support portion, preventing the strut from rotating during steering, thereby separating steering and suspension movements to reduce frictional resistance and enhance steering properties and control stability, while maintaining a simplified mechanical structure and reducing component count.

Engineering Contradiction Analysis
1Device complexity
If the knuckle arm and strut are integrally coupled to perform steering and suspension movements together, then the structure is simple and manufacturing cost is low, but steering frictional resistance increases and steering quality decreases
Solution Approach 1:
The invention divides the movement functions by separating the strut (suspension movement) from the knuckle arm (steering movement). The stabilizer link is coupled to prevent the strut from rotating during steering, allowing the knuckle arm to rotate independently for steering while the strut remains stationary, thus reducing steering frictional resistance and improving steering quality while maintaining structural simplicity.
2Ease of operation
If a double wishbone suspension system is used to separate steering and suspension movements, then steering frictional resistance is reduced and steering quality is high, but the structure becomes complicated and manufacturing cost increases
Solution Approach 1:
The invention extracts only the necessary function from the double wishbone system - preventing strut rotation during steering - and implements it through a simplified stabilizer link mechanism. Instead of using complex top and bottom control arms as in double wishbone systems, the patent uses a stabilizer link integrally coupled to a support portion, achieving the same steering quality improvement with significantly reduced structural complexity.
3Stability of the object's composition
If stabilizer bars and links are integrated into the suspension system, then roll rigidity is increased, but device complexity and manufacturing cost increase
Solution Approach 1:
The invention merges the stabilizer link function with the support portion by integrally coupling them. The stabilizer link is designed as a single piece that connects the stabilizer bar to the support portion, eliminating the need for separate mounting brackets, bolts, and other fastening components. This integration maintains roll rigidity while reducing the number of parts and simplifying the overall structure.

AI summary
The present invention is directed to providing a strut suspension system configured to improve a steering property by reducing steering frictional resistance when a steering wheel is rotationally manipulated and having a relatively simple mechanical structure to reduce the number of components and manufacturing costs and to secure a large space for installing main components such as an engine and the like. Disclosed is a strut suspension system configured to absorb impact and vibrations transferred to a vehicle body from a road surface through a wheel. The strut suspension system includes a strut provided between the vehicle body and the wheel and to which a knuckle arm connecting a steering system of a vehicle to the wheel is connected to be relatively rotatable when the steering system performs steering and a stabilizer link having one end connected to a stabilizer bar configured to increase roll rigidity of the vehicle body and the other end coupled to prevent the strut from rotating.
