An input shaft structure for connecting a motor () and a gearbox () is provided, wherein the input shaft structure comprises a main shaft (), an input end of the main shaft is located within the motor, and is connected to a rotor of the motor, an output end of the main shaft is located within the gearbox, and is connected to a driving gear () of the gearbox, and all of the two ends and an middle portion of the main shaft are provided with a bearing () to perform axial positioning, wherein a hub (-) of the driving gear extend toward two sides, and an inner bore of the hub matches with a shaft diameter of the main shaft to perform radial positioning, to ensure a concentricity of the driving gear and the main shaft. The motor shaft and the input shaft of the gearbox are designed as an integral input shaft, which reduces the entire axial size of the power section, facilitates the layout of the entire vehicle, and has a smaller weight. The two ends of the driving gear are added radial positioning, to ensure a concentricity of the driving gear and the main shaft, which improves the stability of the system.

Input shaft structure having connected motor and speed reducer

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.
