The invention provides a double-electric-drive speed reducer, a pure electric driving force system with the double-electric-drive speed reducer and a vehicle. The double-electric-drive speed reducer is characterized in that a first gear is meshed with an output gear of a first motor; the first connecting shaft is arranged in the first gear, the first connecting shaft can move relative to the first gear along the axis of the first connecting shaft, and the first connecting shaft is selectively connected with a wheel on one side of the Y direction of the vehicle; the second gear is meshed with an output gear of the second motor; the second connecting shaft can move relative to the second gear along the axis of the second connecting shaft, a second spline groove is formed in the second gear, and the second connecting shaft is selectively connected with a wheel on the other side of the vehicle in the Y direction. A first tooth part is arranged at the end, facing the second connecting shaft, of the first connecting shaft, a second tooth part is arranged at the end, facing the first connecting shaft, of the second connecting shaft, and the first tooth part and the second tooth part are arranged in an engaged mode. The problem that an electric drive system cannot meet the requirement for the endurance mileage while meeting the requirement for the strong power performance of the off-road vehicle is solved.
本发明提供了一种双电驱减速器及具有其的纯电驱动力系统、车辆,包括:第一齿轮与第一电机的输出齿轮啮合;第一连接轴设置于第一齿轮内部,第一连接轴沿自身轴线可相对于第一齿轮运动,第一连接轴与车辆Y向的一侧车轮可选择地连接;第二齿轮与第二电机的输出齿轮啮合;第二连接轴沿自身轴线可相对于第二齿轮运动,第二齿轮内部设置有第二花键槽,第二连接轴与车辆Y向的另一侧的车轮可选择地连接;第一连接轴朝向第二连接轴的一端设置有第一齿部,第二连接轴朝向第一连接轴的一端设置有第二齿部,第一齿部和第二齿部可啮合地设置。本申请解决了电驱系统无法在满足越野车辆强动力性需求的同时满足续航里程需求的问题。
