Suspension Strut Laminated Mount Without Separate Bearings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional anti-vibration devices are costly and require complex structures that increase the assembly time and material costs.
Innovation Solution
An anti-vibration device comprising an extension and retraction section with a damper rod and cylinder, a strut mount section, a suspension spring section, a support section, and a laminated section with alternating annular rubber and rigid layers, which eliminates the need for bearings and integrates multiple components into a single, cost-effective structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional anti-vibration devices use bearings between strut mount and support member, then vibration absorption is effective, but manufacturing cost and device complexity increase
Solution Approach 1:
The patent combines the bearing function with the suspension spring support structure by integrating the bearing directly into the support member that supports the coil spring. This merging eliminates the need for separate bearing components while maintaining the vibration absorption function, thereby reducing device complexity and manufacturing cost without sacrificing reliability
Solution Approach 2:
The support member is designed to serve multiple functions: it supports the coil spring, provides bearing functionality for the strut mount, and contributes to the overall structural integrity. This multi-functionality reduces the total number of components needed while maintaining effective vibration absorption
2Reliability
If conventional anti-vibration devices use bearings, then vibration absorption is effective, but manufacturing cost increases
Solution Approach 1:
The bearing function is merged into the support member structure, eliminating the need for separate bearing components. This integration reduces the total number of parts that need to be manufactured, assembled, and inventoried, thereby reducing manufacturing cost while maintaining vibration absorption effectiveness
Solution Approach 2:
The patent extracts the bearing function from its traditional separate component form and integrates it into the support member. This extraction and integration approach simplifies the manufacturing process by reducing the number of discrete components while preserving the essential vibration absorption capability
