Two-Core Damping Valve Assembly for Adjustable Shock Absorbers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shock absorbers with single damping values fail to meet the increasing demands for improved ride comfort and adaptability to different road conditions and driving modes, necessitating adjustable damping solutions.
Innovation Solution
A damping valve device with a simplified structure, featuring fixedly connected or integrally formed components, including a valve sleeve, first and second valve cores, and an elastic element, which allows for adjustable damping without relative movement, enhancing assembly efficiency and reducing costs while maintaining stable damping performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single damping value is used in the shock absorber, then the structure is simple, but it cannot meet the increasing demands for improved ride comfort and adaptability to different road conditions
Solution Approach 1:
The damping valve is segmented into multiple independent valve cores (first valve core and second valve core) that can move relative to each other along the axial direction. Each valve core has different damping characteristics, allowing the system to adapt to different road conditions by selecting which valve core is active, thus providing adjustable damping without significantly increasing structural complexity
Solution Approach 2:
The valve cores are designed to be movable relative to each other, transforming the static single-damping-value system into a dynamic adjustable system. The first valve core can move along the axial direction relative to the second valve core, enabling real-time adjustment of damping characteristics based on road conditions and driving modes
2Adaptability or versatility
If multiple valve cores are used to achieve adjustable damping, then adaptability improves, but assembly complexity and potential assembly issues increase
Solution Approach 1:
The first valve core is nested within the second valve core, with both valve cores located within the valve sleeve. The orthographic projection relationship ensures proper positioning and nesting of components, simplifying the assembly process while maintaining adjustable damping capability through the relative movement of the nested valve cores
3Ease of manufacture
If the end cap part and annular main body part are separately assembled, then manufacturing flexibility is maintained, but assembly issues and production costs increase
Solution Approach 1:
The end cap part and annular main body part are fixedly connected or integrally formed as a unified second valve core structure. This merging eliminates the need for separate assembly of these components, reducing assembly steps and potential assembly issues while maintaining manufacturing flexibility through the choice of fixed connection or integral formation
