The invention relates to a multi-motor power system and an electric tractor, the power system comprises a front drive motor, a rear drive part, a front axle input shaft and an output shaft, the front axle input shaft can rotate around the axial direction of the front axle input shaft, and the front axle input shaft is connected with a first transmission assembly; the front drive motor is installed at the rear end of the front axle input shaft, and the drive end of the front drive motor extends in the axial direction of the front axle input shaft and is in transmission connection with the front axle input shaft through a second transmission assembly. The output shaft is mounted outside the rear end of the front axle input shaft, is coaxial or parallel to the front axle input shaft, and can axially rotate around the output shaft; the rear driving part is installed at the front end of the output shaft and is in transmission connection with the front end of the output shaft through a third transmission assembly, the rear end of the output shaft communicates with a fourth transmission assembly, and the fourth transmission assembly is used for being connected with two rear wheels. The tractor is compact in structure and reasonable in design, switching of multiple working modes is achieved, the working efficiency is improved, the energy utilization rate is increased, and the gear shifting problem of a traditional tractor is solved.

    本发明涉及一种多电机动力系统及电动拖拉机,该动力系统包括前驱电机、后驱动件、前桥输入轴和输出轴,前桥输入轴可绕自身的轴向转动,其与传动组件一连接;前驱电机安装在前桥输入轴的后端,其驱动端沿前桥输入轴的轴向延伸,并通过传动组件二与前桥输入轴传动连接;输出轴安装在前桥输入轴的后端外,其与前桥输入轴同轴或平行,且其可绕自身轴向转动;后驱动件安装在输出轴的前端,其通过传动组件三与输出轴的前端传动连接,输出轴的后端与传动组件四连通,传动组件四用于连接两个后车轮。本发明结构紧凑,设计合理,实现多种工作模式的切换,提高作业效率,提高能量利用率,解决传统拖拉机换挡等问题。
