Driving system and vehicle

The invention provides a driving system and a vehicle comprising the same. The driving system comprises a shell, and an input shaft, an intermediate shaft, an output shaft, a main speed reducer and a differential mechanism which are arranged in the shell; the input shaft is constructed as a hollow shaft, and at least part of the input shaft is sleeved outside the output shaft, so that the input shaft and the output shaft are coaxially arranged; the input shaft and the intermediate shaft are arranged in parallel, and a gear driving gear is fixedly connected to the input shaft. A gear driven gear meshed with the gear driving gear and a wet clutch are arranged on the intermediate shaft, and the gear driven gear is connected to the intermediate shaft by being connected with the wet clutch; the intermediate shaft is connected with a differential through a main reducer; the output shaft is connected with the differential. According to the technical scheme, through coaxial arrangement of the input shaft and the outp
