The invention relates to the technical field of electric vehicle transmission control, in particular to a power-interruption-free multi-mode dual-motor coupling drive axle which comprises a drive axle shell, a left drive motor, a right drive motor, a left mode switching assembly, a right mode switching assembly, a differential mechanism, a left half shaft and a right half shaft. The system has three working modes including a single-motor one-gear centralized driving mode, a dual-motor one-gear centralized driving mode and a dual-motor two-gear distributed driving mode, and can meet the requirements of economy and active safety of the vehicle under complex working conditions. And the three working modes of the non-power-interruption multi-mode dual-motor coupling drive axle can realize non-power-interruption switching, so that vehicle impact caused by mode switching is reduced, and the mode switching time is shortened. The system has a distributed driving mode, and the active safety of the vehicle and the trafficability of the vehicle on a severe road surface can be remarkably improved.

    本发明涉及电动汽车传动控制技术领域,具体是一种无动力中断多模式双电机耦合驱动桥,包括驱动桥壳体、左侧驱动电机、右侧驱动电机、左侧模式切换总成、右侧模式切换总成、差速器、左侧半轴、右侧半轴。本发明具有单电机一挡集中式驱动模式、双电机一挡集中式驱动模式、双电机二挡分布式驱动模式等三种工作模式,可以满足车辆在复杂工况下的经济性和主动安全性的需求。并且所述无动力中断多模式双电机耦合驱动桥的三种工作模式之间可以实现无动力中断切换,减小了因模式切换导致的车辆冲击,缩短了模式切换的时间。本发明具有分布式驱动模式,能够显著提升车辆的主动安全性和恶劣路面的通过能力。
