Bearing Bracket Axle Support Mounting for Mixed Drive Configurations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for mounting axle drive units on vehicle axles complicate production logistics in mass production, as they require different axle supports for single-axle and dual-axle drive vehicles, leading to increased material usage and costs.
Innovation Solution
A fastening assembly that includes a bearing bracket arranged between the axle support and vehicle body, which can be screwed on at least one attachment point, allowing for identical axle support production regardless of axle drive presence, with an optional spacer element for non-driven axles, enabling efficient fastening of both longitudinal and transverse forces, torques, and tilting moments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different axle supports are produced for single-axle and dual-axle drive vehicles, then the mounting requirements for different drive configurations are met, but production logistics are complicated and material usage increases
Solution Approach 1:
The patent applies universality by designing a single standardized axle support that can serve both single-axle and dual-axle drive configurations. The axle support includes standardized attachment points that can accommodate different mounting scenarios, eliminating the need for separate axle support variants and simplifying production logistics while maintaining adaptability to different drive requirements
2Adaptability or versatility
If different axle supports are produced for single-axle and dual-axle drive vehicles, then the mounting requirements for different drive configurations are met, but material usage and costs increase
Solution Approach 1:
The patent eliminates redundant material usage by creating a universal axle support design that replaces multiple specialized components with a single multi-functional part, thereby reducing total material consumption while still accommodating different drive configurations through standardized attachment interfaces
Solution Approach 2:
The patent applies segmentation by separating the axle support into modular components with standardized attachment points, allowing the same base structure to be used across different configurations while only adding or removing specific mounting elements as needed, thus optimizing material usage
3Strength
If a bearing bracket is added for mounting axle drive units, then secure fastening of axle drive units is achieved, but the number of components increases
Solution Approach 1:
The patent merges the bearing bracket function with the existing axle support structure by integrating the mounting capabilities directly into the standardized attachment points of the universal axle support, thereby achieving secure fastening of axle drive units without adding separate bearing bracket components
