Wheel Hub Cover Assembly Threaded Connector Elastic Seal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cover assemblies for wheel rim hubs are prone to detachment, allowing dust and moisture to enter and are inconvenient to assemble and disassemble due to reliance on screws and fragile engaging feet.
Innovation Solution
A cover assembly featuring a ring-shaped outer cover, a connector with a threaded connection and elastic rings that securely covers the hub, preventing dust and moisture entry while allowing easy assembly and disassembly through a threaded connection and ergonomic grip features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If engaging feet are used to connect side cover body to main cover body, then assembly is simple, but connection reliability is poor and parts are easily broken
Solution Approach 1:
The connector is divided into a connector body and a connector ear, where the connector body threads onto the hub and the connector ear engages with the main cover body. This segmentation allows the threaded connection to provide reliable fixation while the engaging feet maintain simple assembly operations.
2Strength
If multiple screws are used to fasten main cover body to hub, then connection strength is improved, but assembly complexity increases
Solution Approach 1:
The connector combines the functions of multiple screws into a single threaded component. The connector body with external threads engages with the hub's internal threads, providing strong fixation while eliminating the need for multiple separate fastening operations, thus reducing assembly complexity.
3Device complexity
If engaging feet are used for connection, then device complexity is reduced, but protection against dust and moisture is insufficient
Solution Approach 1:
The first elastic ring acts as a flexible sealing element that fills the gap between the connector body and the hub inner peripheral wall. This elastic seal prevents dust and moisture from entering through the threaded connection interface while maintaining the simple structure of the engaging feet.
4Ease of operation
If simple engaging feet are used, then assembly is easy, but durability is poor due to breakage
Solution Approach 1:
The first elastic ring provides beforehand cushioning by sealing the connection interface between the connector body and hub, preventing dust and moisture from degrading the engaging feet over time. This protective sealing extends the service life of the engaging feet while maintaining easy assembly operations.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively prevents dust and moisture from entering the hub while enabling quick and tool-free assembly and disassembly of the cover assembly, enhancing durability and convenience.
Implementation Method 1
The first elastic ring is sleeved on the connector inner annular wall and is configured to be disposed between and abut against the connector inner annular wall and the hub inner peripheral wall
Implementation Method 2
The connector inner annular wall extends through the cover central hole for connection with the hub inner peripheral wall, and has an outer wall surface provided with a first external thread for threadedly connecting with the first internal thread
