A Study on Modeling the Temperature of Vehicle Transmission Device

In order to study the components temperature and the transmission oil temperature that flowing through the components of vehicle transmission device, based on the basic theory of heat transfer, this paper establishes heat production model, component temperature model and transmission oil temperature model of the vehicle transmission, calculates the models coupling and iterative, compares the calculating results with testing results. The results show that the maximum relative error of transmission temperature between the calculating results and the testing results is less than 10%.
