An electric tractor double motor transmission device and its control strategy |
| abstract |
A dual-motor transmission device for an electric tractor and a control strategy thereof relate to the technical field of electric tractors. The present invention transmits power to a PTO output shaft (9-3) and an output shaft gear A (7) respectively through a double planetary row coupling mechanism (6). ‑1), by operating the locking and releasing of the PTO output shaft brake (9‑2), the ring gear brake (6‑4) and the output shaft brake (7‑3), the front row planetary gear mechanism and the rear row planetary gear mechanism The power and torque of the PTO drive motor (4) and the power drive motor (5) can be merged and divided through the shared ring gear (6‑3) of the double planetary row, and the high and low speed switching mechanism (8) can realize high and low speed by changing the gear ratio. The switch makes up for the lack of motor speed regulation, and sets the neutral position at the same time; the utilization rate of the motor is improved through the confluence and shunt control of the motor, and the adaptability of the tractor is increased. |
