Locking Device Synchronizes Power Assemblies for Vehicle Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicle power transmission systems with wheel-side drive, the power assembly occupies excessive space, leading to unreasonable vehicle layout and complex mounting/dismounting processes, and independent power components for each wheel result in reduced vehicle functionality when one wheel slips or a motor fails.
Innovation Solution
A locking device with synchronizing rings and driving components allows for selective synchronization of power components between wheels, enabling synchronized rotation and independent operation, thus maintaining vehicle functionality even if one wheel slips or a motor fails.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If independent power components are used for each wheel, then wheel-side drive functionality is achieved, but vehicle functionality is reduced when one wheel slips or a motor fails
Solution Approach 1:
The patent combines two independent power components into a unified power transmission system through a locking device that can selectively synchronize the output shafts. This merging allows power to be transmitted from one working power component to both wheels when one component fails or one wheel slips, thereby improving operational reliability while maintaining adaptability.
Solution Approach 2:
The locking device provides dynamic connectivity between the two power components, allowing the system to switch between independent operation mode and synchronized operation mode based on actual driving conditions. This dynamic adjustment enables the system to adapt to different scenarios (normal driving, wheel slip, motor failure) and maintain high reliability.
2Ease of operation
If wheel-side drive form is adopted, then power transmission to wheels is achieved, but power assembly occupies large space and vehicle layout is unreasonable
Solution Approach 1:
The patent merges two separate power assemblies into a more compact integrated structure by sharing common components and using a locking device to connect the output shafts. This consolidation reduces the overall space occupied by the power assembly while maintaining the wheel-side drive capability and power transmission efficiency.
3Adaptability or versatility
If wheel-side drive form is adopted, then independent wheel drive is achieved, but mounting and dismounting steps are complicated
Solution Approach 1:
The locking device integrates the mounting and dismounting functions into a unified mechanism that can simultaneously connect or disconnect both power components. This integration simplifies the mounting and dismounting process compared to handling two independent power assemblies separately, while preserving the independent wheel drive capability.

AI summary
A locking device comprising: first and second flanges; and first and second flange locking structures. The first and second flange locking structures are used for selectively locking the first flange and the second flange. Each flange locking structure comprises: a synchronising ring and a driving assembly. The synchronising ring is able to slide relative to the corresponding flange; and the drive assembly is capable of selectively pushing the synchronising ring to slide along the axial direction of the corresponding flange from an unlocked position to a locked position.
