The invention relates to the technical field of transmission, in particular to a double-motor four-gear electric drive transmission system and a vehicle. The invention provides a dual-motor four-gear electric drive transmission system. The dual-motor four-gear electric drive transmission system comprises a first motor, a second motor, a first power output shaft, a second power output shaft, a first middle rotating shaft, a second middle rotating shaft, an output shaft, a first middle shaft tooth mechanism, a second middle shaft tooth mechanism, a first gear shifting mechanism, a second gear shifting mechanism, a third gear shifting mechanism and a fourth gear shifting mechanism. According to the double-motor four-gear electric drive transmission system, multiple different working conditions of two sets of motor power sources can be achieved, four power transmission paths are constructed in the power transmission system, and in the gear shifting process, switching among the four power transmission paths is achieved by controlling the four gear shifting devices, so that it is guaranteed that power is not interrupted during gear shifting, and the gear shifting efficiency is improved. The gear shifting pause feeling in the driving process is reduced, power switching is smoother, and the comfort and safety of a vehicle are good.

    本发明涉及传动技术领域,尤其涉及一种双电机四挡电驱动传动系统及车辆。本发明提供的双电机四挡电驱动传动系统,包括:第一电机、第二电机、第一动力输出轴、第二动力输出轴、第一中转轴、第二中转轴、输出轴、第一中间轴齿机构、第二中间轴齿机构、第一换挡机构、第二换挡机构、第三换挡机构及第四换挡机构。本发明提供的双电机四挡电驱动传动系统,可以实现两套电机动力源的多种不同工况,动力传动系统中构建有四个动力传动路径,在换挡过程中,通过控制四个换挡装置,实现四个动力传动路径之间的切换,从而保障换挡时的动力不中断,降低行车过程中的换挡顿挫感,动力切换更加平顺,车辆的舒适性和安全性较好。
