The invention relates to a double-motor single-speed two-stage speed reduction parallel-axis electric drive axle. The invention belongs to the technical field of new energy vehicles. The problems thatan existing single motor is high in energy loss, low in transmission efficiency and poor in power performance are mainly solved. The electric drive axle is mainly characterized by comprising a firstmotor, a second motor, a first half shaft, a second half shaft, a first speed reducer assembly and a second speed reducer assembly; the first motor and the second motor are respectively arranged on the first speed reducer assembly and the second speed reducer assembly; the first speed reducer assembly and the second speed reducer assembly each comprise an input gear, a first-stage speed reductiongear, a second-stage speed reduction gear, an output gear and an intermediate shaft; the first-stage reduction gears and the first second-stage reduction gears are arranged on the intermediate shafts;the first half shaft, the second half shaft, the first motor shaft and the second motor shaft are parallel. The electric drive axle has the characteristics of dual-motor driving, mutual independenceof left and right transmission systems, elimination of a mechanical differential mechanism and saving of chassis space, and is mainly used for single-speed two-stage speed reduction parallel-axis electric drive axle.

    本发明为一种双电机单速二级减速平行轴电驱桥。属于新能源汽车技术领域。它主要是解决现有单电机存在能量损耗高、传输效率低和动力性较弱的问题。它的主要特征是:包括第一、二电机,第一、二半轴,第一、二减速器总成;第一、二电机分别安装在第一、二减速器总成上;第一、二减速器总成均包括输入齿轮,一、二级减速齿轮,输出齿轮和中间轴;一级减速齿轮和第一二级减速齿轮设置在中间轴上;第一、二半轴、第一、二电机轴相互平行。本发明具有双电机驱动、左右传动系统相互独立、取消机械差速器和节省底盘空间的特点,主要用于单速二级减速的平行轴电驱桥。
