Abstract

Abstract: Three new oil passage structures were designed to improve the lubricating and cooling efficiency based on the original one. Gas-liquid phase dynamic characteristics of oil passage were solved by VOF(volume of fluid) method in order to study the effects of lubricant flow rate distribution， oil filling efficiency and oil discharge rate of different oil passage structures. The results showed that the eddy can be avoided by arranging the oil passage holes， and these holes can promote the uniform distribution of the oil flow rate. Among them， the V-shaped oil passage structure was superior to other structures in the aspects such as the distribution of oil flow rate， the overall oil filling efficiency of the friction gaps and the circulation rate of the lubricating oil， which is helpful to improve the lubricating and cooling efficiency， reduce the heat generation，and extend the service life of wet clutch.
