The invention discloses a commercial vehicle double-motor three-stage transmission electric drive axle assembly, and belongs to the field of new energy commercial vehicle electric drive axle assemblies, the commercial vehicle double-motor three-stage transmission electric drive axle assembly comprises two sets of motors and two sets of speed reducer systems, a first drive motor drives a first speed reducer assembly to transmit power, and a second drive motor drives a second speed reducer assembly to transmit power; and the two transmit power to the differential mechanism together, and transmit the power to left and right wheels through left and right half shafts to drive the vehicle to run. The two speed reducer assemblies respectively adopt three-stage transmission, so that larger torque is transmitted at a large speed ratio; each speed reducer is provided with two gears for a user to select and shift gears, so that the transmission efficiency is higher; the system is longitudinally arranged and is symmetrical about a half shaft, so that the production cost is saved, the production period is shortened, and the suspension arrangement space can be increased to adapt to different suspension systems; under the condition that the center distance is not changed, the spatial positions of the three shafts of the single speed reducer can be adjusted, and different whole vehicle arrangement requirements can be met.
本发明公开了一种商用车双电机三级传动电驱动桥总成,属于新能源商用车电驱动桥总成领域,包括两套电机及两套减速器系统,第一驱动电机驱动第一减速器总成传输动力,第二驱动电机驱动第二减速器总成传输动力,两者共同将动力传输到差速器,并分别通过左右半轴传递至左右车轮,驱动车辆行驶。两个减速器总成分别采用三级传动,大速比传递更大扭矩;每个减速器设置两个挡位供用户选换挡,传递效率更高;系统纵向布置,以半轴对称,不仅节省生产成本,缩短生产周期,而且可以增大悬架布置空间,以适应选配不同的悬架系统;在中心距不变的情况下,单个减速器三个轴的空间位置可调整,能适应不同的整车布置要求。
