Multi-link Suspension Decoupling Damper for Camber Gain
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
MacPherson strut suspension systems limit the range of motion and camber gain in high-performance vehicle applications, failing to maximize handling potential and vehicle stability.
Innovation Solution
A multi-link suspension system is introduced, decoupling the damper from the upright and adding upper links to enhance camber and roll characteristics, while retaining the shock absorber and spring in their original locations, allowing for increased angular displacement and improved vehicle dynamics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a MacPherson strut arrangement is used, then a compact suspension arrangement is achieved, but the range of motion and camber gain are insufficient for high performance applications
Solution Approach 1:
The MacPherson strut assembly is segmented into separate functional components: the shock absorber remains integrated with the strut, while the spring is separated and mounted independently on the upper control arm. This segmentation allows each component to be optimized independently, enabling greater range of motion and camber gain while maintaining compact overall packaging.
Solution Approach 2:
The spring mounting location is moved from the traditional vertical strut position to the upper control arm, representing a dimensional change in the suspension architecture. This repositioning allows the spring to accommodate larger angular displacements and camber changes while the shock absorber maintains its vertical orientation for compact packaging.
2Device complexity
If the MacPherson strut arrangement is used, then structural simplicity is maintained, but handling potential and vehicle stability are not maximized
Solution Approach 1:
By segmenting the suspension system into separate shock absorber and spring assemblies with independent mounting locations, the system achieves MacPherson-like simplicity while incorporating multi-link characteristics that improve handling performance and vehicle stability through enhanced camber gain and range of motion.
Solution Approach 2:
The modified arrangement combines the simplicity of the MacPherson strut with the performance characteristics of multi-link suspension systems. The shock absorber maintains vertical mounting for compactness while the independently mounted spring on the upper control arm provides enhanced camber gain, creating a hybrid system that delivers both simplicity and high-performance handling.
