The invention discloses an inter-wheel torque distribution electric drive axle with a dual-motor torque coupling function. The inter-wheel torque distribution electric drive axle comprises a main drive motor (100), a main rotation speed reducer (200), a differential mechanism (300), a right half shaft (400), a mode switching mechanism (500), an internal and external meshing duplex planetary gear mechanism (600), a cylindrical gear transmission mechanism (700), a torque distribution motor (800) and a left half shaft (900). According to the invention, the output torques of the main drive motor (100) and the torque distribution motor (800) and the position of the combination sleeve of the mode switching mechanism (500) are controlled; therefore, four working modes including a main driving motor independent driving mode, a torque distribution motor independent driving mode, a main driving motor-torque distribution motor torque coupling driving mode and a main driving motor driving torque inter-wheel distribution mode can be realized. Through reasonable switching of the four working modes, the dynamic property, the economical efficiency and the handling stability of the vehicle under the complex working conditions can be effectively improved.

    本发明公开了一种具有双电机转矩耦合功能的轮间转矩分配电驱动桥,包括:主驱电机(100)、主转减速器(200)、差速器(300)、右半轴(400)、模式切换机构(500)、内外啮合双联行星齿轮机构(600)、圆柱齿轮传动机构(700)、转矩分配电机(800)、左半轴(900)。本发明通过控制主驱电机(100)和转矩分配电机(800)的输出转矩以及模式切换机构(500)的结合套位置,即可实现主驱电机独立驱动模式、转矩分配电机独立驱动模式、主驱电机‑转矩分配电机转矩耦合驱动模式、主驱电机驱动转矩轮间分配模式四种工作模式。本发明通过四种工作模式的合理切换,可以有效提升车辆在复杂工况下的动力性、经济性和操纵稳定性。
