Axle Housing Bracket Positioning Protrusions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing axle housing and brake housing fixing methods require the use of co-fastening bolts and jigs, which are time-consuming to install and remove, and often result in bolt interference and increased manufacturing costs.
Innovation Solution
An axle housing supporting structure that uses a connecting member, such as a retaining bolt, to secure the axle housing and brake housing to the axle bracket without a jig, allowing co-fastening bolts to connect all components simultaneously, reducing the number of bolts and avoiding interference issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If co-fastening bolts are used to fix the axle housing and brake housing to the axle bracket, then the components can be securely fastened together, but the assembly process becomes time-consuming and requires dedicated positioning jigs
Solution Approach 1:
The brake housing is designed with positioning protrusions that fit into corresponding positioning recesses on the axle bracket before the co-fastening bolts are installed. This preliminary positioning action eliminates the need for dedicated positioning jigs and allows the components to be accurately positioned during assembly, reducing assembly time while maintaining fixing reliability
Solution Approach 2:
Positioning protrusions and recesses act as intermediary elements between the brake housing and axle bracket, providing automatic alignment and positioning functionality. These intermediaries enable the co-fastening bolts to be installed without requiring complex positioning jigs, thus reducing assembly time while ensuring reliable fixation
2Strength
If multiple co-fastening bolts are used to secure the axle housing and brake housing, then the components are firmly fixed, but the number of bolts increases leading to interference issues and higher manufacturing costs
Solution Approach 1:
The positioning protrusions and recesses are integrated directly into the brake housing and axle bracket structures, combining the positioning function with the structural components themselves. This eliminates the need for separate positioning devices and reduces the overall number of fastening elements required, thereby reducing interference issues and manufacturing costs while maintaining fixing strength
Solution Approach 2:
The positioning protrusions and recesses serve multiple functions: they provide positioning alignment, structural support, and guidance for bolt installation. This multi-functionality reduces the need for additional dedicated positioning components and minimizes the number of bolts required, thereby reducing device complexity and manufacturing costs while maintaining adequate fixing strength

AI summary
An axle housing supporting structure includes an axle housing, a brake housing, an axle bracket for supporting the axle housing and the brake housing, a connecting member inserted in the axle housing and the axle bracket to connect the axle housing and the axle bracket for preventing the axle housing from falling from the axle bracket, and at least one co-fastening bolt fastening the axle bracket, the brake housing, and the axle housing together.
