Shock Absorber Bracket Structure for Stable Lightweight Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The efficiency of assembling a shock absorber to an attachment member is not optimal, particularly when using aluminum-based materials for weight reduction, as the stability and surface pressure of the fastening components may not be sufficiently secured.
Innovation Solution
The shock absorber features a bracket with outwardly extending parts that include hole portions and reduced-rigidity parts at specific positions, allowing for easier assembly and enhanced fastening stability without increasing the fastening axial force, while maintaining product strength and preventing interference with other components.

1Weight of moving object
If aluminum-based materials are used for weight reduction, then weight decreases, but fastening stability and surface pressure may not be sufficiently secured
Solution Approach 1:
The extension parts are designed with non-uniform thickness, featuring a first region with greater thickness and a second region with lesser thickness. This local variation in material distribution optimizes the balance between overall weight reduction and localized fastening stability, allowing the aluminum-based bracket to maintain sufficient surface pressure at fastening locations while achieving weight reduction.
Solution Approach 2:
The invention changes the geometric parameters of the extension parts by varying their thickness across different regions. By adjusting the thickness parameter from the first region to the second region, the design achieves optimal fastening characteristics while maintaining weight reduction benefits of aluminum-based materials.
2Productivity
If the bracket structure is simplified for easier assembly, then assembly efficiency improves, but structural integrity may be compromised
Solution Approach 1:
The bracket is segmented into distinct regions with different thickness characteristics - a first region with greater thickness for structural support and a second region with lesser thickness for ease of assembly. This segmentation allows each region to fulfill its specific function while maintaining overall structural integrity.
Solution Approach 2:
The extension parts are pre-formed with the varying thickness configuration during manufacturing, eliminating the need for additional assembly steps or adjustments. This preliminary structuring enables straightforward assembly while ensuring structural integrity is built-in from the start.

AI summary
This shock absorber includes an outer cylinder, and a bracket having a pair of extension parts. The outer cylinder has an opening and into which the inner cylinder is inserted and fixed. The pair of extension parts extend outward in a radial direction of the outer cylinder from different positions spaced apart in a circumferential direction of the outer cylinder. A hole portion and a reduced-rigidity part are provided in the pair of extension parts. The hole portion is provided at a position facing an attachment hole of an attachment member disposed between the pair of extension parts. The reduced-rigidity part is disposed at a disposition position on the outer cylinder side of the hole portion at the same position as the hole portion in the axial direction of the outer cylinder. The reduced-rigidity part has a lower rigidity than a position different from the disposition position.
