The synchronizer slip mechanism in the slip ring and cone of the automated manual transmission(AMT) is investigated with respect to relative velocity, fluid gap magnitude and lubricant supply flow rate in order to find better design parameters for less drag torque and higher power transfer efficiency. Fluid spaces inside the gaps of the AMT synchronizer module are modeled in detail for CFD(FLUENT) analysis. Fluid flow behaviors through the gap space of AMT synchronizer module are calculated in terms of volume of fluid and dynamic pressure. This study focuses on the formation of fluid fraction of fluid space inside the synchronizer module and drag torque on the synchronizer friction surfaces, which are investigated according to the design and operational parameters of the synchronizer module. Computational results based on real design and operational parameters are compared to yield useful design guides on the less drag torque of the synchronizer system. |
