Gearbox Oil Line Layout for Variant-Reduced Injection Lubrication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transmission systems face challenges with limited installation space due to the use of pipelines for injection lubrication, which also require separate designs for each transmission variant, leading to inefficiencies and increased complexity.
Innovation Solution
A transmission system with an oil line featuring two structurally identical outlet openings that can be selectively closed using a closure element, allowing for adaptable oil supply to lubrication points without the need for separate pipeline designs for each transmission variant.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If pipelines are used for injection lubrication, then lubrication can be supplied to transmission components, but installation space is limited and separate pipeline designs are required for each transmission variant
Solution Approach 1:
The oil line is designed with multiple outlet openings that can be selectively closed using closure elements. This universal design allows a single oil line structure to serve multiple transmission variants by simply closing different outlet openings, eliminating the need for separate pipeline designs for each variant while maintaining adaptability to different lubrication requirements
Solution Approach 2:
The oil line is segmented into multiple outlet openings along its length. Each outlet opening can be independently controlled by a closure element, allowing selective activation of specific lubrication points based on the transmission variant. This segmentation enables flexible adaptation without requiring complete redesign of the pipeline system
2Ease of manufacture
If separate pipeline designs are implemented for each transmission variant, then each variant can be optimized, but manufacturing efficiency decreases and complexity increases
Solution Approach 1:
A single universal oil line design with multiple outlet openings can be manufactured once and used across all transmission variants in a series. The adaptability to different variants is achieved through selective closure of outlet openings rather than through separate pipeline designs, significantly improving manufacturing efficiency while maintaining customization capability
Solution Approach 2:
The system allows adaptation to different transmission variants by changing operational parameters (which outlet openings are closed) rather than changing the physical structure of the oil line. This parameter-based adaptation maintains manufacturing efficiency while providing versatility across different transmission configurations
3Adaptability or versatility
If multiple outlet openings are provided in the oil line, then adaptability to different transmission configurations is improved, but the structure becomes more complex
Solution Approach 1:
The oil line features multiple outlet openings positioned at different locations along its length, creating an asymmetric structure that can be adapted to different transmission configurations. This asymmetric design with selectively closable outlets provides flexibility in oil supply configuration while maintaining a relatively simple overall structure compared to having completely separate pipelines for each variant

Function Achieved in This Case
This solution enables efficient lubrication of transmission systems by allowing the oil supply to be adapted to different transmission configurations without structural changes, ensuring effective lubrication of rotating components.
Implementation Method 1
The closure element can be used to close either the first or the second outlet opening in an oil-tight manner
Implementation Method 2
The cavity conducts the oil from the inlet opening to the at least one outlet opening
