Power Transfer Device Integrated Pipe Holding Partition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing power transfer devices face challenges in the assembly and holding of working oil supply pipes, often requiring additional components like clamps, which increases complexity and reduces assemblability.
Innovation Solution
The power transfer device incorporates a partitioning member with a holding portion on the first case member to securely insert and hold the working oil supply pipe, eliminating the need for additional components like clamps, thereby simplifying the assembly process and reducing the number of components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a clamp member is used to hold the working oil supply pipe, then the pipe can be securely held, but the number of components increases and assemblability deteriorates
Solution Approach 1:
The holding portion is integrated into the partitioning member as a unified structure, eliminating the need for separate clamp members. The partitioning member simultaneously performs its primary function of separating chambers and the secondary function of holding the working oil supply pipe through its integrated holding portion, thereby reducing component count while maintaining holding stability
Solution Approach 2:
The partitioning member is designed to serve multiple functions: it partitions the storage chamber from the differential chamber, structurally supports the working oil supply pipe through its holding portion, and provides a mounting surface for the reservoir plate. This multi-functionality reduces the overall number of components needed in the differential device
2Manufacturing precision
If additional clamp members are used to hold the working oil supply pipe, then the pipe positioning is improved, but the assembly process becomes more complex and time-consuming
Solution Approach 1:
The holding portion is formed as an integral part of the partitioning member, combining the positioning and holding functions into a single structural element. This integration eliminates the need for separate assembly steps for installing clamp members, thereby improving assembly efficiency while maintaining precise pipe positioning
Solution Approach 2:
The holding portion is pre-formed as part of the partitioning member structure, so that when the partitioning member is installed, the working oil supply pipe is automatically positioned and held in the correct location. This preliminary preparation of the holding structure eliminates the need for additional positioning operations during assembly

AI summary
A flange portion of a reservoir plate is provided with a holding portion that holds a working oil supply pipe disposed on a converter housing and that is composed of an overhanging portion formed so as to overhang toward the converter housing and a dented portion formed in the overhanging portion along the working oil supply pipe. Consequently, it is possible to reduce the number of components and achieve better assembly compared to a configuration in which another member such as a clamp member is used to hold the working oil supply pipe. Since the holding portion is formed in a complex shape from the overhanging portion and the dented portion with recesses and projections, moreover, the strength of the holding portion against bending etc. can be enhanced.
