A variety of dual-motor dynamic coupling structure schemes based on planetary gear mechanism are designed,and the quantitative relations of various dynamic coupling devices are obtained by using lever analysis method.Then,the transmission characteristics of each scheme are compared and analyzed,and two better schemes are selected for power matching and parameter calculation.Based on Simulation X,the simulation model of the dual motor dynamic coupling device is built,the kinematics simulation analysis is carried out,and the final transmission scheme is optimized.The results show that the proposed method can effectively reduce the number of coupling transmission schemes,and the selected dynamic coupling transmission scheme has excellent speed and torque performance,which can meet the operating requirements of electric tractor under multi-working conditions of electric tractors.This research has important theoretical significance to the development of planetary gear train and automobile transmission.
