Abstract
The application relates to a pure electric driving system and a vehicle. The pure electric driving system comprises a shell, a motor installed in the shell and provided with a rotor and a stator, an input shaft fixedly connected with the rotor and capable of rotating under the driving of the rotor, wherein the input shaft is provided with a first-gear driving gear and a second-gear driving gear, a differential coaxially arranged with the input shaft, a half shaft coaxially arranged with the input shaft and in driving connection with the differential, an intermediate shaft coaxially arranged with the input shaft and capable of being in engagement with the differential, and a multi-mode clutch arranged on the intermediate shaft and capable of being selectively coupled or decoupled with one of the first-gear driving gear and the second-gear driving gear. The pure electric driving system has the advantages of compact structure, reasonable layout, wide power regulation range and high transmission efficiency.
