Power Transmission Apparatus Clutch Chamber Oil Strainer Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing power transmission apparatuses face the risk of oil surface depletion in clutch chambers due to oil being forced into the gear chamber during rotation, leading to insufficient lubrication.
Innovation Solution
The apparatus is designed with a rotating shaft extending along the vehicle's width, featuring gears, clutches, and an oil pump system where the gear chamber includes a gear accommodating portion and a strainer accommodating portion, with one clutch chamber communicating only through the strainer accommodating portion, preventing direct communication with the gear chamber to avoid oil introduction during rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the clutch chamber directly communicates with the gear chamber through a communicating hole, then oil exchange is facilitated, but oil is forced into the gear chamber during rotation causing excessive oil surface decrease in the clutch chamber
Solution Approach 1:
The gear chamber is divided into two separate accommodating portions: a gear accommodating portion for the driven bevel gear and a strainer accommodating portion for the oil strainer. The clutch chamber communicates only with the strainer accommodating portion through the communicating hole, preventing direct communication with the gear accommodating portion. This segmentation isolates the oil circulation path to prevent oil from being forced into the gear chamber during rotation while maintaining oil exchange capability.
Solution Approach 2:
The strainer accommodating portion acts as an intermediary chamber between the clutch chamber and the gear accommodating portion. Oil flows from the clutch chamber through the communicating hole into the strainer accommodating portion, and then to the gear accommodating portion. This intermediary structure prevents direct communication between the clutch chamber and gear accommodating portion, eliminating the problem of oil being forced into the gear chamber during rotation.
2Device complexity
If the clutch chamber directly communicates with the gear accommodating portion, then oil circulation is simplified, but lubrication reliability deteriorates due to insufficient oil volume
Solution Approach 1:
The gear chamber is segmented into gear accommodating portion and strainer accommodating portion. The clutch chamber communicates only with the strainer accommodating portion, creating a controlled oil circulation path. This segmentation maintains relatively simple oil circulation while ensuring that oil is not lost to the gear accommodating portion during rotation, thereby maintaining sufficient oil volume for reliable lubrication.
Solution Approach 2:
The strainer accommodating portion serves as an intermediary that controls oil flow between the clutch chamber and gear accommodating portion. This intermediary structure ensures that oil circulates through the strainer for filtration before reaching the gear accommodating portion, maintaining oil quality and volume for reliable clutch lubrication without overly complicating the circulation system.

AI summary
The power transmission apparatus is a power transmission apparatus mounted on a vehicle. A gear chamber includes a gear accommodating portion used for accommodating a gear and a strainer accommodating portion used for accommodating an oil strainer. The gear accommodating portion and the strainer accommodating portion are disposed abreast in an axial direction. One clutch chamber of a pair of clutch chambers adjacent to the strainer accommodating portion only directly communicates with the strainer accommodating portion of the gear accommodating portion and the strainer accommodating portion, and the one clutch chamber communicates with the gear accommodating portion only by using the strainer accommodating portion.
