Engine Lubrication Structure Using Clutch Oil Spray
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lubrication systems for mission gear mechanisms are complex, leading to increased crankcase complications and the number of parts, requiring a forced lubricating system like an oil jet, which complicates the engine design.
Innovation Solution
A lubrication structure with oil introduction ports between the clutch and mission chambers, positioned to allow upward oil recovery and efficient supply to the main shaft, utilizing a countershaft with a hollow portion as an oil path and extension walls to collect and direct lubricating oil, simplifying the oil supply and avoiding crankcase complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a forced lubricating system such as an oil jet is used to supply lubricating oil to the main shaft and countershaft, then reliable lubrication can be achieved, but the crankcase becomes complicated and the number of parts increases
Solution Approach 1:
The clutch mechanism itself generates the oil spray through its rotational motion, eliminating the need for external oil jets or forced lubrication systems. The rotating clutch plates automatically atomize and distribute lubricating oil to the main shaft and countershaft, making the system self-servicing and reducing crankcase complexity while maintaining reliable lubrication
2Reliability
If a complicated oil supplying path is formed in the mission case or mission holder to supply lubricating oil to the main shaft and countershaft, then lubrication can be achieved, but the structure becomes complex and requires additional parts
Solution Approach 1:
The oil supply function is extracted from the mission case and mission holder structures and relocated to the clutch mechanism. By removing the complicated oil paths from these components and using the clutch mechanism's rotation to generate and distribute oil, the patent simplifies the overall structure while ensuring reliable lubrication supply to all necessary components
3Productivity
If oil introduction ports with upward openings are provided in the clutch chamber to recover oil mist, then oil recovery efficiency is improved, but the clutch chamber structure becomes more complex
Solution Approach 1:
The clutch chamber structure serves multiple functions: it contains the clutch mechanism, generates oil spray through rotation, and recovers oil mist through strategically positioned upward openings. By integrating these functions into a single multi-functional component rather than adding separate systems, the patent improves oil recovery efficiency without significantly increasing overall structural complexity

AI summary
A lubrication structure is provided for supplying lubricating oil to a transmission of an engine. The engine includes a mission holder which includes a power transmission mechanism between a main shaft and a countershaft as a unit and is removably mounted in a mission chamber, and a clutch chamber having a clutch mechanism is provided adjacent the mission chamber for transmitting rotation of a crankshaft to the transmission. Two oil introduction ports are provided on the mission holder, which is between the clutch chamber and the mission chamber. The two oil introduction ports enable the two chambers to communicate with each other. Each of the oil introduction ports has an opening provided therein which opens upwardly on a clutch chamber side of the mission holder.
