Wheel Suspension Articulated Via Strut to Reduce Weight and Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wheel suspensions for motor vehicles face challenges in optimizing installation space and weight, often requiring additional components and material that increase weight and reduce camber stability, while also limiting the use of space for other essential components.
Innovation Solution
The wheel suspension design eliminates the need for a bearing point on the vehicle body for the upper suspension arm, allowing it to be articulated exclusively via the strut, and flexibly couples the strut to the lower suspension arm, reducing the number of parts and weight, and allowing for more efficient use of installation space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a bearing point on the vehicle body is used for the upper suspension arm, then the suspension structure is stable, but the installation space requirement increases and weight increases
Solution Approach 1:
The patent removes the bearing point from the vehicle body for the upper suspension arm, extracting this component from the traditional suspension structure. The upper suspension arm is now articulated exclusively via the strut, eliminating the need for a separate bearing point on the vehicle body, thereby reducing installation space requirements while maintaining suspension functionality.
Solution Approach 2:
The patent combines the functions of the bearing point and the strut by articulating the upper suspension arm exclusively via the strut. This merging eliminates redundant components and reduces the overall installation space while maintaining the structural stability needed for suspension operation.
2Reliability
If additional components are added to the suspension system, then the structural stability is improved, but the vehicle weight increases
Solution Approach 1:
The patent extracts the bearing point component from the vehicle body, eliminating it entirely from the suspension system. This reduction in component count directly decreases vehicle weight while the strut maintains the necessary articulation and structural stability for the upper suspension arm.
Solution Approach 2:
By merging the bearing function into the strut itself, the patent eliminates redundant components. The strut performs both its primary function and the articulation function previously handled by a separate bearing point, reducing overall weight while maintaining structural integrity.
3Reliability
If the upper suspension arm is articulated via a bearing point on the vehicle body, then the articulation is stable, but the camber stability is reduced
Solution Approach 1:
The patent removes the bearing point from the vehicle body, eliminating the source of camber instability. By extracting this component, the upper suspension arm achieves more stable camber characteristics while maintaining reliable articulation through the strut alone.
