The invention discloses a double-motor double-speed parallel-axis independent suspension electric drive axle. The invention belongs to the technical field of automobile manufacturing. The electric drive axle mainly solves the problems that an existing electric drive axle occupies the arrangement space of a chassis structure and influences the arrangement number of batteries. The electric drive axle is mainly characterized by comprising a first motor, a second motor, a gear box, a transmission shaft assembly and an independent suspension system; the gear box comprises a speed reducer assembly,and the speed reducer assembly comprises a first-gear first-level driving gear, a first-gear driven gear, a second-gear first-level driving gear, a second-gear driven gear, a two-gear gear shifting system, a second-level driving gear and a second-level driven gear, wherein the first-gear first-level driving gear and the first-gear driven gear is meshed, and the second-gear first-level driving gearand the second-gear driven gear are meshed; the first motor and the second motor are mounted on the two sides of the gear box respectively; and motor shafts of the first motor and the second motor are parallel to the transmission shaft. The electric drive axle has the characteristics of relatively small occupied chassis structure arrangement space, no influence on the arrangement number of batteries, wide efficient working area of the motors, high energy utilization rate, long driving range of a vehicle and capability of considering the dynamic property and economy of the whole vehicle, and is mainly used for the double-speed parallel-axis independent suspension electric drive axle.

    本发明的名称为一种双电机双速平行轴的独立悬挂电驱动桥。属于汽车制造技术领域。它主要是解决现有电驱动桥存在占用底盘结构布置空间和影响电池布置数量的问题。它的主要特征是:包括第一、第二电机,齿轮箱,传动轴总成,独立悬挂系统;齿轮箱包含减速器总成,减速器总成包括啮合的一档一级主、从动齿轮和二档一级主、从动齿轮,两档换挡系统,二级主、从动齿轮;第一、二电机分别安装在齿轮箱的两侧;第一、二电机的电机轴与传动轴平行。本发明具有占用底盘结构布置空间相对较小、不影响电池布置数量、电机高效工作区宽、能量利用率高、车辆续驶里程长、以及可兼顾整车动力性和经济性的特点,主要用于双速平行轴的独立悬挂电驱动桥。
