The invention belongs to the technical field of new energy vehicles, and discloses a pure electric power system and a vehicle. The pure electric power system comprises a shell, a first power source, a second power source, a first intermediate shaft, a second intermediate shaft and an output shaft, the first power source can be in transmission connection with the first intermediate shaft, the second power source is in transmission connection with the first intermediate shaft, the second intermediate shaft is rotationally arranged on the first intermediate shaft in a sleeving mode, and a planetary gear train without a gear ring is arranged on the second intermediate shaft. The second intermediate shaft is in transmission connection with the first intermediate shaft or the second intermediate shaft is fixed to the shell, so that the output shaft has multiple output states, a gear ring is omitted, the problem that the speed ratio range is small due to the fact that the gear ratio is limited by the gear ring and the sun gear can be solved, the speed ratio range is increased, and the transmission efficiency is improved. The performance is improved, and the vehicle use requirement is met.
本发明属于新能源车辆技术领域,公开了纯电动动力系统及车辆。该纯电动动力系统包括壳体、第一动力源、第二动力源、第一中间轴、第二中间轴和输出轴,第一动力源能够与第一中间轴传动连接,第二动力源与第一中间轴传动连接,第二中间轴转动套设于第一中间轴,第二中间轴上设置有无齿圈行星轮系,进而与输出轴连接,通过将第二中间轴与第一中间轴传动连接或者第二中间轴与壳体固定,进而使得输出轴具有多种输出状态,且取消了齿圈,能够避免受限于齿圈与太阳轮的齿数比,使得速比的范围较小的问题,提升速比范围,进而提升性能,满足车辆使用需求。
