In response to the needs of electric tractors under multiple operating conditions, a dual-motor power coupling drive system is matched. According to its power transmission requirements, a dual planetary gear train dynamic coupling structure scheme and a multi-planetary gear train dynamic coupling structure scheme are proposed. Through example design, the specific parameters of the two schemes are obtained. The transmission efficiency formulas of the two schemes in multiple modes are deduced, the transmission efficiency in each mode is calculated, and the final transmission scheme of the dual-motor power coupling device is optimized based on the transmission efficiency. It provides a theoretical basis and method for the design and analysis of the tractor power coupling device.
