Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing differential systems, the lubricating liquid flows too concentratedly, leading to inadequate contact with all gears, resulting in increased wear, heat buildup, and noise.
Innovation Solution
A differential cover with a diversion structure that includes multiple diversion regions and corresponding diversion structures, guiding the lubricating liquid to flow multi-directionally and ensure full contact with all gears.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the lubricating liquid flows concentratedly in the differential, then the flow path is simple and easy to maintain, but the lubricating liquid cannot contact all gears adequately, resulting in increased wear and heat buildup
Solution Approach 1:
The patent divides the single concentrated flow path into multiple segmented flow paths by adding diversion structures (diversion ribs and diversion plates) within the differential cover. These structures segment the lubricating liquid flow into different directions, ensuring that lubricating liquid reaches various gears including side gears that were previously inadequately lubricated. This segmentation resolves the contradiction by maintaining reliability through improved gear coverage while managing complexity through modular flow division.
Solution Approach 2:
The patent applies local quality by creating different flow characteristics in different regions of the differential. The diversion structures are strategically positioned to create high-velocity flow regions near side gears and other critical components that require enhanced lubrication. This allows the lubricating liquid to have different flow patterns and contact intensities in different local areas, improving overall gear protection without requiring complete system redesign.
2Temperature
If the lubricating liquid flows concentratedly near the ring gear, then the flow dynamics are simple, but heat dissipation is insufficient and noise increases
Solution Approach 1:
The patent transitions from a single-dimension concentrated flow path to a multi-dimensional flow distribution system. The diversion structures create three-dimensional flow patterns that extend lubricating liquid reach toward side gears and other components located in different spatial dimensions. This dimensional expansion improves heat dissipation by increasing the surface area of gear components exposed to lubricating liquid while managing the complexity through structured spatial arrangement.
3Reliability
If the lubricating liquid is stored at the bottom of the differential, then the storage is simple and space-efficient, but the lubricating liquid cannot reach side gears effectively
Solution Approach 1:
The patent incorporates diversion structures during the manufacturing process itself, rather than adding them as separate components. The diversion ribs and plates are integrated into the differential cover design, allowing lubricating liquid flow redirection to be built-in from the start. This preliminary action ensures side gear lubrication is addressed during manufacturing, improving reliability while avoiding the complexity of post-manufacturing assembly modifications.
