Suspension Module Layout Integrating Stabilizer Bar and PE Module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The transition from internal combustion engine vehicles to electric vehicles necessitates reconfiguring suspension systems to accommodate high-capacity batteries and power electronics modules, leading to space inefficiencies and maintainability issues due to separation of components like stabilizer bars and gearboxes.
Innovation Solution
A suspension module design that integrates a stabilizer bar and power electronics module within a unified fixing portion, allowing for optimized space utilization and detachable components for maintenance, utilizing a suspension frame, fixing members, and a penetration member to secure the stabilizer bar and PE module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the stabilizer bar and gearbox are mounted in separate spaces in the suspension system, then each component can be independently positioned, but the utilization of internal vehicle space is degraded
Solution Approach 1:
The patent combines the stabilizer bar and gearbox into a single integrated mounting structure where the stabilizer bar passes through the gearbox housing. This merging of previously separate components into a unified spatial arrangement maximizes the utilization of internal vehicle space by eliminating dedicated separate spaces for each component.
2Power
If high-capacity batteries and PE modules are mounted in the vehicle, then power performance is improved, but the space occupied by these components causes other components to be inevitably detached during maintenance
Solution Approach 1:
The patent segments the suspension system into modular components with independent mounting structures. The stabilizer bar and gearbox are designed as separate but integrated modules that can be independently accessed and maintained. This segmentation allows maintenance personnel to service specific components without necessarily detaching unrelated components, even in vehicles with large battery and PE module installations.
3Volume of moving object
If the stabilizer bar and PE module are fixed to the same fixing portion, then space utilization is maximized, but the structural complexity of the fixing mechanism increases
Solution Approach 1:
The patent designs the fixing portion with multi-functional capabilities where a single structural element serves multiple purposes: it provides mounting for the PE module, guides and positions the stabilizer bar, and maintains structural integrity. This universal fixing mechanism reduces the need for separate dedicated mounting structures for each component.

AI summary
A structure includes a suspension module including a suspension frame, a stabilizer bar provided to face one side of the suspension frame, a fixing portion including one side fixedly coupled to the suspension frame and configured to fix the stabilizer bar relative to the suspension frame, and a power electronics (PE) module fixedly coupled to one side of the fixing portion.
