Problems solved by technology

For example, there are certain limitations in the patent’s use of plastic hoses to replace the lubricating oil passage of the transmission. The patent does not consider the impact of the high-speed rotation of the main oil passage on the lubrication flow, and the device cannot observe the flow field of the lubricating oil in the main oil passage under high-speed rotation. flow state
