The invention discloses a dual-motor driving system for a new energy vehicle. The dual-motor driving system is small in occupied space, light in weight, high in transmission efficiency and large in power density, and the endurance mileage of the new energy vehicle is effectively increased. Research finds that an effective scheme does not exist at present for a commercial vehicle, a motor-speed reducer-transmission shaft-traditional drive axle structure is often adopted, the scheme is simple, only an original engine is replaced by a motor, but the scheme is low in transmission efficiency and large in chassis occupied space, and electric development of the heavy commercial vehicle is limited to a great extent. And the electric trend of new energy commercial vehicles, especially new energy heavy truck vehicles, is facilitated. Along with the research and development and industrialization process of the product, the development process of a new energy heavy commercial vehicle is driven, the dual-motor integrated electric driving force assembly is initiated in the industry, and a brand new development direction is brought to the development of the industry.

    本发明公开了一种用于新能源汽车的双电机驱动系统,本发明占用空间小,且重量轻,传动效率高、功率密度大,有效的提升新能源车辆的续航里程。通过调研发现,针对商用车目前没有行之有效的方案,往往采用电机‑减速器‑传动轴‑传统驱动桥的结构,该方案简单,仅将原来的发动机换成电机,但该方案传动效率低下,底盘占用空间极大,很大程度上限制了重型商用车的电动化发展,有助于新能源商用车,尤其是新能源重卡车辆的电动化趋势。随着该产品的研发及产业化进程,带动了新能源重型商用车的发展进程,在行业内首创双电机集成式电驱动力总成,为行业的发展带来了全新的发展方向。
