Heavy-Vehicle Torque Distributor Layout for Multi-Axle Adaptability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current torque transmission systems in heavy vehicles are inflexible, bulky, and costly, requiring redesign for different traction configurations and struggling to efficiently distribute torque to multiple axles.
Innovation Solution
A compact and versatile torque distributor system that uses a transmission assembly with differential mechanisms and power take-offs, housed within a single casing, allowing for adaptable torque distribution to multiple axles without the need for extensive redesign.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a transmission is specifically designed for one single traction configuration, then the transmission can be optimized for that specific configuration, but the transmission cannot be adapted to other traction configurations without redesign
Solution Approach 1:
The patent implements a universal transmission system that can operate with different numbers of driving axles (2, 3, or 4 axles) by selectively connecting power take-offs to different axles. The transmission assembly includes multiple power take-offs that can be engaged or disengaged based on the required traction configuration, allowing a single transmission design to serve multiple functions and configurations without requiring redesign.
2Adaptability or versatility
If a transmission is designed to split torque to a plurality of axles, then the transmission can distribute torque to multiple axles, but the transmission becomes particularly bulky and heavy
Solution Approach 1:
The transmission system is segmented into modular components including a transmission assembly, multiple differentials, and multiple power take-offs that can be independently connected or disconnected. This segmentation allows the system to distribute torque to multiple axles when needed while maintaining a compact design, as each component is optimized for its specific function and can be selectively engaged rather than requiring a continuously complex multi-axle configuration.
3Volume of moving object
If the transmission is housed within a single casing defining a space, then the transmission components are compactly arranged, but the space utilization must be optimized to accommodate multiple power take-offs and differentials
Solution Approach 1:
The patent combines the transmission assembly, multiple differentials, and multiple power take-offs within a single casing, merging these components into an integrated unit. The casing is designed to house all necessary components in a compact arrangement, with the transmission assembly positioned to efficiently connect to the differentials and power take-offs, reducing the overall volume required compared to separate housing arrangements.
