The invention belongs to the technical field of off-road vehicles, and discloses a dual-motor reduction gearbox, a transmission assembly and an automobile. The number of the input shafts is two, and the input shafts are connected with the motor assemblies on the same side in a one-to-one correspondence mode. The middle shafts are in transmission connection with the input shafts in a one-to-one correspondence mode, and the opposite ends of the two middle shafts are coaxially and rotatably connected in a sleeved mode; the output shafts are in transmission connection with the middle shafts in a one-to-one correspondence mode, and the output ends of the output shafts are connected with half shafts used for being connected with wheels; the input shaft, the intermediate shaft and the output shaft are sequentially arranged in the length direction of the vehicle body. The reduction gearbox has the advantages that the axial size of the reduction gearbox is reduced, the included angle between the half shaft and the horizontal plane is reduced, the included angle is improved, the high chassis design of the off-road vehicle is met, friction at the two ends of the half shaft is reduced, noise is low, and NVH performance is improved.

    本发明属于越野车技术领域,公开了一种双电机减速箱、传动总成及汽车,双电机减速箱包括:两套电机组件;输入轴,设有两根,输入轴与同一侧电机组件一一对应连接;中间轴,与输入轴一一对应地传动连接,且两根中间轴的对置端同轴可转动地套接;以及输出轴,与中间轴一一对应地传动连接,输出轴的输出端连接用于连接车轮的半轴;输入轴、中间轴和输出轴沿车身长度方向依次排列。有益效果:缩小减速箱了的轴向尺寸,半轴与水平面的夹角减小,改善夹角问题,满足越野车高底盘设计,减小半轴两端摩擦,噪音较小,提高NVH性能。
