Transmission Strainer Mounting Through a Partition Oil Path
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power transmission devices face challenges in ensuring the support stability of the strainer without increasing the size of the housing, as vibration from vehicle motion can destabilize the strainer, potentially requiring additional parts and enlarging the housing.
Innovation Solution
The power transmission device incorporates a partition section that supports the strainer and a mechanical oil pump, with the strainer connected to both a first and second oil path, allowing it to be securely anchored within the housing, thereby improving stability without enlarging the housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If additional support parts are added to ensure strainer stability, then support stability is improved, but device complexity and housing size increase
Solution Approach 1:
The partition section is designed to serve multiple functions: it divides the housing into separate chambers, supports the pump assembly, and provides support for the strainer through the second connection port. By making the partition section multi-functional, the patent avoids adding dedicated support structures for the strainer, thereby improving stability without increasing device complexity or housing size.
2Stability of the object's composition
If additional support parts are added to ensure strainer stability, then support stability is improved, but housing size increases
Solution Approach 1:
The partition section is designed to serve multiple functions: it divides the housing into separate chambers, supports the pump assembly, and provides support for the strainer through the second connection port. By making the partition section multi-functional, the patent avoids adding dedicated support structures for the strainer, thereby improving stability without increasing device complexity or housing size.
Solution Approach 2:
The strainer is positioned within the housing space in a nested arrangement, with its support structure integrated into the existing partition section. The second connection port of the strainer is received by the partition section, allowing the strainer to be supported within the existing housing volume without requiring additional space or enlarging the housing.
3Stability of the object's composition
If the strainer is supported by the partition section, then support stability is improved, but manufacturing complexity increases
Solution Approach 1:
The housing is divided into separate chambers by the partition section, and the strainer is positioned to span across these chambers. The first connection port connects to the pump in one chamber while the second connection port connects to the partition section. This segmentation allows the strainer to be supported by existing structural elements without requiring complex integrated designs, maintaining ease of manufacture while improving stability.

AI summary
A power transmission device for a vehicle includes a housing that accommodates a power transmission mechanism, a partition section that supports the power transmission mechanism and divides an interior of the housing, a strainer arranged at a bottom of the housing, and a pump supported by the partition section. The housing defines a first chamber located on one side of the partition section in a direction of an axis of rotation of the power transmission device, and a second chamber located on the other side of the partition section. The strainer has a first connection port that connects to the pump, and a second connection port that connects to a second oil path inside the partition section, the second connection port connecting to the second oil path from a direction of assembly of the pump onto the partition section.
