Study on Flow Characteristic of Lubricant in the Main Shaft of Transmission in Commercial Vehicle

In this study, numerical simulation has been performed to investigate the flow characteristic of lubricant in the main shaft of transmission in commercial vehicle. It was confirmed that the mass flow rate of lubricating oil depends on the length of branch and the rotating rate of shaft. As a result, it could be verified that the discharged flow rate is considerably influenced by the length of the branch of main shaft. This study suggests the optimal design data for the lubrication system of the transmission in commercial vehicle.
