Gearbox Lubrication Chute With Oil Guard Siphon for Fast Restart
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gearbox lubrication systems in vehicles with 'stop-start' systems suffer from prolonged oil supply interruptions due to long oil supply lines, leading to potential premature damage of components like bearings and gears, as the oil pump restart time is delayed, causing insufficient lubrication.
Innovation Solution
A lubrication system with an oil distribution chute and a supply line featuring an oil guard siphon, which includes a collection zone, siphon zone, and distribution zone, along with a U-shaped siphon or reservoir to create an oil reserve, ensuring quick lubrication by minimizing the distance from the tapping point to the lubrication spout.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the oil supply line is made long to extend between the tapping point and the distribution chute, then the oil can reach all components, but the restart time of the oil pump increases and lubrication is insufficient
Solution Approach 1:
The patent introduces a siphon structure that creates a U-shaped oil reserve zone, storing oil in advance in the collection zone. When the pump stops, this pre-stored oil remains in the supply line, allowing immediate lubrication upon restart without waiting for the pump to refill the entire line, thus reducing restart time while maintaining lubrication continuity
Solution Approach 2:
The patent utilizes hydraulic principles by designing a siphon-based oil supply system where the U-shaped configuration creates a hydraulic seal and oil trap. The siphon structure leverages gravity and pressure differential to maintain oil in the collection zone, ensuring rapid oil delivery to the distribution chute when needed without requiring the pump to refill the entire supply line
2Adaptability or versatility
If the distance between the tapping point and the distribution chute is considerable, then the oil can reach distant components, but the oil supply line length increases and restart time increases
Solution Approach 1:
The siphon structure pre-stores oil in the collection zone along the supply line, creating a distributed oil reserve. This allows the system to maintain lubrication capability over long distances without proportionally increasing restart time, as the oil is already positioned in the supply line rather than requiring pump refilling from the tank
Solution Approach 2:
The siphon acts as an intermediary element between the oil tank and the distribution chute. It creates intermediate oil storage zones along the supply line, enabling the system to bridge long distances while maintaining rapid response capability through locally stored oil in the siphon's U-shaped configuration
