The invention discloses an electric tractor transmission system, and particularly relates to a new energy vehicle, comprising a main motor in transmission connection with an output shaft through a speed reducer; the speed reducer comprises a first planetary gear set and a second planetary gear set which are coupled; the energy storage flywheel is driven by the auxiliary motor to rotate; and the auxiliary coupling mechanism comprises an auxiliary gear which is movably arranged, and the auxiliary gear moves along with insufficient torque of the main motor. Through the energy storage flywheel, when a heavy load occurs in the output process of the main motor, the auxiliary motor drives the energy storage flywheel to rotate and store energy, and then when heavy load driving is carried out for the first time, the auxiliary gear moves along with insufficient torque of the main motor; and the auxiliary gear is driven to be close to and coupled with the first planetary gear set and the energy storage flywheel, so that the power of the energy storage flywheel is transmitted to the first planetary gear set, the output torque of the speed reducer is increased, the torque of the main motor is compensated, and load driving is carried out.
本发明公开了一种电动拖拉机传动系统,具体涉及新能源车辆,包括:主电机,其通过减速机与输出轴传动连接;减速机,其包括耦合的第一行星齿轮组和第二行星齿轮组;蓄能飞轮,其提供辅电机驱动旋转;辅耦机构,其包括活动设置的辅齿轮,所述辅齿轮随所述主电机扭矩不足而移动。本发明通过蓄能飞轮,在主电机进行输出的过程中,出现重负载的情况时,通过辅电机驱动蓄能飞轮进行旋转蓄能,而后进行第一次重负载行驶时,辅齿轮会随主电机的扭矩不足而移动,驱使辅齿轮向所述第一行星齿轮组和所述蓄能飞轮靠近耦合,从而传递蓄能飞轮的动力至第一行星齿轮组上,以增加减速机的输出扭矩从而补偿主电机的扭矩,以进行负载行驶。
