Abstract:
A vehicle electrically driving assembly, connected to the rear or front axle half shaft of the vehicle, that includes: an electric motor, a speed reducer, an electromagnetic tooth-mounted clutch and a differential. The speed reducer has multiple stages of gears, an input shaft and an intermediate shaft; the differential is connected between the axle half shafts; the electromagnetic tooth-mounted clutch is installed on the input shaft or the intermediate shaft of the speed reducer or on the axle half shafts. When the electromagnetic tooth-mounted clutch is in engagement, driving force of the electric motor is transmitted to the vehicle axle via the speed reducer and the electromagnetic jaw clutch, to provide an auxiliary driving force to the vehicle. When the power of the entire vehicle is insufficient at the acceleration phase, the electrically driving assembly, by using the electromagnetic jaw clutch, provides an auxiliary driving force to the entire vehicle.
