Research and Analysis on Lubrication and Energy Loss of New Energy Vehicle Reducer
The new energy vehicle reducer is an important part that affects the transmission efficiency of the powertrain,and it is of great significance to study the lubrication and energy loss of the reducer.When the lubri-cating oil volume is changed from 0.8 L to 0.7 L,the lubrication effect of the two oil volumes is analyzed in this paper,and it is calculated that the positive 0.7 L stirring power of 0.107 kW is better than that of 0.8 L stirring power of 0.135 kW.Inverting 0.7 L oil mixing power to 0.115 kW is better than 0.8 L oil mixing power to 0.181 kW.By using MASTA software to calculate the minimum efficiency without considering the oil mixing loss of 98.6％,using 0.7 L oil to consider the minimum efficiency of 98.2％,and the maximum efficiency differ-ential was only 0.4％,0.7 L can be selected as the oil volume.
