The invention provides a double-motor electric driving device and a driving method.The driving device comprises a gear shifting element, a first motor, a second motor and at least two rows of first planetary gear trains which are arranged on a rack, the first planetary gear trains in the front row are in driving connection with the first motor, and second connectors are arranged on the first planetary gear trains in the rear row; when the gear shifting element is in a first gear, the first combining piece is combined with the second combining piece; the differential mechanism is in driving connection with a third connector, the rear row first planetary gear train is connected with the third connector, and when the gear shifting element is located at the second gear, the first connector is combined with the third connector; the second motor is in driving connection with the differential through the second planetary gear train; the problem that in the related technology, under the high-speed driving working condition, due to the unicity of the driving mode and the inflexible motor torque distribution mode, the use efficiency of the motor is low is solved.
本发明提供了一种双电机电驱动装置及驱动方法,驱动装置包括设于机架上的换挡元件,第一电机、第二电机,至少两排第一行星轮系,均设置在机架上,前排第一行星轮系与第一电机驱动连接,后排第一行星轮系上设置有第二结合件,换挡元件处于第一档位时,第一结合件与第二结合件结合;差速器上驱动连接有第三结合件,后排第一行星轮系与第三结合件连接,换挡元件处于第二档位时,第一结合件与第三结合件结合;第二电机通过第二行星轮系与差速器驱动连接;解决了相关技术中的在高速行驶的工况下,由于驱动模式的单一性与不灵活的电机扭矩分配方式,导致电机的使用效率低下的问题。
