Shock Absorber Housing Reinforcement via Extension Panel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional shock absorber housing reinforcement structures fail to effectively absorb and disperse vibrations, leading to increased acceleration noise, road transfer noise, and deteriorated ride and handling performance, noise, vibration, harshness (NVH) performance, and marketability of vehicles due to lack of connectivity between the shock absorber mounting portion and the sub-frame mounting portion.
Innovation Solution
A reinforcing structure for the shock absorber housing that includes a front fender apron inner panel connected to the shock absorber mounting panel and the front side member, with an extension panel extending from the overlapped portion to the sub-frame mounting portion, forming closed sectional surfaces that protrude and are coupled by spot welding, enhancing rigidity without additional components and improving forming efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the conventional shock absorber housing reinforcement structure is used with extension panel connected between front side member and shock absorber mounting panel, then the rigidity of the shock absorber housing is improved, but acceleration noise and road transfer noise increase due to lack of connectivity between shock absorber mounting portion and sub frame mounting portion
Solution Approach 1:
The extension panel is modified to directly connect the shock absorber mounting portion to the sub-frame mounting portion, merging previously separate structural functions into a single continuous load path. This integration enables effective vibration absorption and noise reduction while maintaining structural rigidity.
2Object-generated harmful factors
If additional reinforcing components are added to improve connectivity and reduce noise, then NVH performance is improved, but the number of components and manufacturing complexity increase
Solution Approach 1:
The extension panel is designed to perform multiple functions simultaneously: it reinforces the shock absorber housing rigidity, provides structural connectivity between mounting portions, and acts as a vibration absorption path. This multi-functionality eliminates the need for separate reinforcing components while improving NVH performance.
3Strength
If the shock absorber housing structure is reinforced with multiple separate panels and members, then the structural strength is improved, but the weight and manufacturing cost increase
Solution Approach 1:
Multiple separate reinforcing panels and members are merged into a single integrated extension panel structure that connects the shock absorber mounting portion to the sub-frame mounting portion. This consolidation maintains structural strength while reducing the total weight and manufacturing cost by eliminating redundant components.

AI summary
A structure for reinforcing a shock absorber housing includes a shock absorber housing connecting a shock absorber mounting panel and a front side member. A front fender apron inner panel connects the shock absorber mounting panel and the front side member. The front fender apron inner panel is coupled to an outer surface of the shock absorber housing and overlapped with a portion of the shock absorber housing to form a wheel house with the shock absorber housing. An extension panel is connected from a side of the overlapped portion of the shock absorber housing and the front fender apron inner panel to a sub-frame mounting portion of the front side member.
