Coaxial Bidirectional Electromagnetic Clutch for Compact Torque Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electromagnetic clutches in new energy vehicles can only transmit torque in one direction, requiring two clutches which occupy excessive space and limit spatial configuration.
Innovation Solution
A bidirectional electromagnetic clutch integrating two electromagnetic clutches along the same axis, allowing independent engagement and disengagement at different ends, reducing space occupancy and enabling flexible layout.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two electromagnetic clutches are used to transmit torque in both directions, then torque transmission capability is improved, but space occupancy increases and space layout flexibility is reduced
Solution Approach 1:
The patent merges two electromagnetic clutches into a single integrated bidirectional electromagnetic clutch assembly. The first and second electromagnetic clutches share a common housing, magnetic circuit components, and control system, allowing both to be housed in a compact configuration that would otherwise occupy the space of only one clutch. This combining approach enables bidirectional torque transmission while reducing the total space required.
Solution Approach 2:
The bidirectional electromagnetic clutch assembly serves multiple functions within a single device: it can transmit torque in both directions (forward and reverse), provide independent engagement and disengagement of first and second clutches, and control power flow between different components. This multi-functionality eliminates the need for separate clutch assemblies for different operating modes, thereby reducing space occupancy.
