The utility model discloses a central drive type electric drive system which comprises a motor, a speed change mechanism and a hub drive sleeve, the speed change mechanism is installed on a motor shaft of the motor, the hub drive sleeve is sleeved on the motor shaft of the motor and located between the speed change mechanism and a rotor of the motor, and the motor shaft transmits power to the hubdrive sleeve through the speed change mechanism. According to the central driving type electric driving system adopting the technical scheme, compared with a central driving type electric driving system designed in the past by a practical team, the problems that a motor assembly, a reduction gearbox and a hub structure are poor in mutual independence and difficult to disassemble and assemble, partconnecting and fixing modes are mutually overlapped, and the number of parts is large are effectively solved; by the adoption of the structure, assembling, disassembling and maintaining are more convenient, the size and weigh
