The invention provides an electrically-driven tractor CVT power assembly with a rear-mounted power take-off (PTO) structure. The structure comprises an engine, a generator, a main driving motor, a transmission, a PTO motor, a PTO transmission case, a front axle, a rear axle, a transfer case and an energy storage unit, the engine is in transmission connection with the generator, the main driving motor is in transmission connection with the transmission, the transmission is in transmission connection with the rear axle, the transmission is further in transmission connection with the transfer case, and the transfer case is in transmission connection with the front axle through a front driving shaft; the PTO motor is in transmission connection with the PTO transmission box; and the energy storage unit is electrically connected with the generator, the main driving motor and the PTO motor. According to the electrically-driven tractor CVT power assembly with the rear-mounted power take-off (PTO) structure, the characteristics that the motor is low in speed, large in torque and wide in rotating speed range are utilized, gear switching of a transmission is not carried out, the motor is directly used for speed regulation, and stepless speed change in the operation process is achieved.

    本发明提供一种后挂电PTO结构的电驱式拖拉机CVT动力总成,包括:发动机、发电机、主驱动电机、变速器、PTO电机、PTO传动箱、前桥、后桥、分动箱和储能单元,所述发动机与发电机传动连接,所述主驱动电机与变速器传动连接,所述变速器与后桥传动连接,所述变速器还与分动箱传动连接,所述分动箱通过前驱动轴与前桥传动连接;所述PTO电机与PTO传动箱传动连接;所述储能单元分别与发电机、主驱动电机和PTO电机电连接;本发明提供的后挂电PTO结构的电驱式拖拉机CVT动力总成,利用电机低速大扭矩、转速范围宽的特性,不进行变速器档位切换,直接使用电机调速,实现了作业过程的无级变速。
