Segmented Cushion Ring for Shock Absorber Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shock absorber systems require disassembly for replacing damaged cushion rubber members, which is inconvenient and time-consuming.
Innovation Solution
A cylinder device with a piston rod and annular cushion ring formed by linking ring segments, allowing for easy replacement of the cushion ring without disassembling the shock absorber by restricting radial movement through linkage portions and facilitating cleaning and water discharge through groove passages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a cylindrical cushion rubber member with an axial core hole is used, then the piston rod can be inserted through it, but the shock absorber must be disassembled to replace the cushion rubber member when damaged
Solution Approach 1:
The cushion ring is divided into multiple arc-shaped ring segments that can be separated and reassembled. Each ring segment can be independently removed and replaced without disassembling the entire shock absorber, allowing maintenance personnel to quickly replace damaged segments by simply opening the linkage portions.
2Ease of repair
If the cushion ring is formed by linking multiple ring segments, then individual segments can be replaced without disassembly, but the structure becomes more complex with linkage portions
Solution Approach 1:
The linkage portions are designed with movable and adjustable characteristics, allowing them to be easily opened and closed. The first and second linkage portions can be separated to remove ring segments and reconnected to form the complete annular structure, providing dynamic accessibility for maintenance while maintaining structural integrity during operation.
3Ease of manufacture
If groove passages are added to discharge water and allow cleaning, then maintenance is improved, but the manufacturing complexity increases
Solution Approach 1:
The linkage portions are designed with groove passages that create channels for water and cleaning fluid flow. These grooves allow cleaning solutions to penetrate through the linkage portions to reach and clean the inner surfaces of the cushion ring and piston rod, facilitating easy maintenance without disassembly.

Function Achieved in This Case
Enables easy replacement and maintenance of the cushion ring without disassembling the shock absorber, maintaining operational repulsive force and improving productivity by allowing individual segment manufacturing and cleaning.
Implementation Method 1

AI summary
A cylinder device includes an annular cushion ring that prevents collision between the cylinder head and the rod head at stroke end during contraction. The cushion ring is formed by linking a plurality of ring segments in a circumferential direction so as to have an annular shape. The ring segments have a main body portion and linkage portions formed on both ends of the main body portion in the circumferential direction, the linkage portions linking the neighboring ring segments. The linkage portions of the neighboring ring segments are mutually overlapped in an axial direction of the cushion ring and linked such that relative movement in a radial direction of the cushion ring is restricted.
