Steady-State Thermal Analysis of Electric Vehicle Two - Speed Automatic Transmission

An energy loss during the operation of the Electric 2-Speed Automatic Transmission, which will generate heat and make the transmission bear a thermal load. Therefore, it is necessary to make a steady-state thermal analysis of transmission. In this paper, the mathematical model of transmission is established based on the theory of heat transfer. Based on the finite element theory, the temperature field distribution and heat flux distribution of the whole transmission are solved. The results show that the modification of the gear height on the addendum can reduce the temperature of the gear; Transmission lubrication system need to be further optimized; The heat convection between the wall surface of the box has little effect on the temperature. The temperature of each part conform to the requirements of the transmission. The analysis results provide a theoretical basis for the optimization of transmission efficiency.
