The invention relates to a double-motor power coupling device and a control method thereof. The double-motor power coupling device comprises a driving motor, a PTO motor and a double-row planetary gear coupler, wherein the driving motor is mainly used for transmitting power to a variable-speed drive axle, and the PTO motor is mainly used for driving a rotary tillage mechanism. By arranging a firstplanet row gear coupling mechanism, a second planet row gear coupling mechanism, a stepless transmission mechanism, an electromagnetic lock and a synchronizer, confluence and shunt of power of two motors are controlled; and the double-row planetary gear coupler can coordinate two power working areas so that the problem that a high-power driving system is large in size can be solved, the application range of an electric tractor can be enlarged, and therefore the dynamic property and economical efficiency of the electric tractor are improved.
本发明涉及双电机动力耦合装置及其控制方法,包括主要把动力传递给变速驱动桥的驱动电机、主要用于驱动旋耕机构的PTO电机和双排行星齿轮耦合器,通过设置第一行星排齿轮耦合机构、第二行星排齿轮耦合机构、无级传动机构、电磁锁止器和同步器以实现控制两个电机动力的汇流与分流;双排行星齿轮耦合器能够协调两个动力的工作区域,不仅可以有效解决大功率驱动系统体积大的限制,还可以增加电动拖拉机的应用范围,提高了电动拖拉机的动力性和经济性。
