The invention relates to the technical field of electric vehicles, and especially relates to a single-motor pure electric power system and a vehicle. The system comprises a driving motor, a planet row, a system output shaft, a first locking clutch, a second locking clutch and a first clutch, the driving motor is connected with one end of the first locking clutch, the other end of the first lockingclutch is connected with a sun gear of the planet row, one end, used for connecting the driving motor, of the first locking clutch is connected with a system output shaft through the first clutch, aplanet carrier of the planet row is connected with one end of the second locking clutch, the other end of the second locking clutch is connected with one end, used for connecting the system output shaft, of the first clutch, and a gear ring of the planet row is locked on a shell. When the first locking clutch and the second locking clutch are loosened and the first clutch is combined, a direct drive mode is formed, the first locking clutch and the second locking clutch are loosened, and the sun gear and a planet carrier do not rotate synchronously along with the first locking clutch and the second locking clutch, so that energy loss is reduced, and the electric energy utilization rate is increased.
本发明涉及电动车辆技术领域,特别是一种单电机纯电动力系统及车辆。该系统包括驱动电机、行星排、系统输出轴、第一锁止离合器、第二锁止离合器和第一离合器,驱动电机连接第一锁止离合器的一端,第一锁止离合器的另一端连接行星排的太阳轮,第一锁止离合器的用于连接驱动电机的一端通过第一离合器连接系统输出轴,行星排的行星架连接第二锁止离合器的一端,第二锁止离合器的另一端连接第一离合器的用于连接系统输出轴的一端,行星排的齿圈锁止在壳体上,当第一锁止离合器和第二锁止离合器松开,第一离合器结合时构成直驱模式,第一锁止离合器和第二锁止离合器松开,太阳轮和行星架不随之同步转动,因此降低了能量损失,提高了电能利用率。
