Locking Apparatus for Synchronized Power Transmission
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 layouts and complex mounting/dismounting processes, and independent wheel motors result in reduced vehicle functionality when one wheel slips or a motor fails.
Innovation Solution
A power transmission system incorporating a locking device that synchronizes power components for each wheel, allowing the vehicle to operate even if one wheel slips or a motor fails, featuring a simple structure with a three-stage reducer and a locking mechanism that connects the power components for synchronized operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wheel-side drive form is adopted with independent power components for each wheel, then each wheel can be driven independently, but the power assembly occupies large space and vehicle layout becomes unreasonable
Solution Approach 1:
The patent merges two independent power assemblies into a single integrated power transmission system. The first and second power components are combined with a common transmission mechanism, allowing both wheels to be driven from a single power source while maintaining independent drive capability. This reduces the overall space occupation compared to having separate power assemblies for each wheel.
Solution Approach 2:
The transmission mechanism serves multiple functions: it can transmit power to both wheels simultaneously, allow independent wheel operation, and provide differential motion when needed. The locking mechanism adds another function by enabling synchronized operation when one wheel slips or a motor fails, making the system universally adaptable to various driving conditions while occupying less space.
2Adaptability or versatility
If independent wheel motors are used, then each wheel can operate independently, but mounting and dismounting steps become complicated
Solution Approach 1:
By combining the mounting of two independent power assemblies into a single integrated unit, the number of mounting steps is reduced. The first and second power components are mounted together with the transmission mechanism as one assembly, simplifying the installation process while maintaining the capability for independent wheel operation.
3Ease of operation
If power components for each wheel are independent, then each wheel can be controlled separately, but vehicle functionality is reduced when one wheel slips or motor fails
Solution Approach 1:
The locking mechanism acts as an intermediary between the two power components. When one wheel slips or a motor fails, the locking mechanism can engage to synchronize the operation of both wheels, allowing the vehicle to continue functioning by transferring power from the working wheel to the non-working wheel. This maintains vehicle operational capability while preserving separate wheel control during normal operation.

AI summary
The present invention discloses a locking device, a power assembly, a power transmission system and a vehicle. The locking device includes: a first flange, the first flange being adapted to be fixed on the first shaft; a second flange, the second flange being adapted to be fixed on the second shaft; a synchronizing ring, the synchronizing ring being normally connected to the first flange to be adapted to rotate synchronously with the first flange, and the synchronizing ring being slidable relative to the first flange; and a driving component, the driving component selectively pushing the synchronizing ring to slide from an unlocked position to a locked position in an axial direction of the first flange. When the synchronizing ring is in the locked position, the synchronizing ring is connected to the second flange be adapted to rotate the second flange synchronously with the first flange. When the synchronizing ring is in the unlocked position, the synchronizing ring is separated from the second flange. The locking device according to embodiments of the present invention can realize the single-way locking function, and is simple in structure.
