AI Technical Summary
In the existing technology, the oil passage layout of the engine body is difficult, which makes it difficult to meet the oil supply needs of various systems. Especially in the compact layout of the front end area, the lubricating oil cannot reach all parts that need lubrication smoothly, which affects the overall operating efficiency of the engine and the coordinated work of various components.
Design a structure for connecting the gear chamber to the engine block, including a gear chamber housing, a gear chamber cover, and a central gear shaft. The output oil passage inside the central gear shaft is connected to the lubrication oil passage on the gear chamber cover to form an independent lubrication oil circuit system, ensuring that the lubricating oil can flow directly to the gear transmission mechanism and the chain transmission mechanism, reducing the dependence on the oil passage inside the engine block.
It achieves full lubrication of various systems in a limited front-end area, reduces the complexity of oil passage design, simplifies the overall engine oil circuit system, reduces manufacturing costs and assembly difficulty, improves lubrication efficiency and transmission system stability, and extends engine service life.
