The invention provides an electric automobile wheel hub motor driving device and an electric automobile operating method. The electric automobile wheel hub motor driving device comprises a motor, a left planetary gear train, a right planetary gear train, a brake mechanism and a controller, wherein the motor comprises a motor shaft rotatably connected to a wheel hub; a left clutch and a right clutch are arranged at two ends of the motor shaft respectively and are both connected to the controller; each of the left planetary gear train and the right planetary gear train comprises a sun gear, at least three rotary positioning planetary gears and an inner gear ring fixed on the inner wall of the wheel hub; all the planetary gears are uniformly distributed around the circumference of the sun gear and are meshed with the sun gear; all the planetary gears are located in the inner gear ring and are meshed with the inner gear ring; two sun gears are symmetrically mounted at the left end and the right end of the motor shaft and rotate relative to the motor shaft; the left clutch and the right clutch are controlled to be in connected or disconnected state by the controller. Through the electric automobile wheel hub motor driving device, the rotation stability of wheels of the electric automobiles and the flexibility of the steering control of the automobile can be greatly improved.
Description
technical field [0001] The invention relates to the technical field of driving electric vehicles, in particular to a wheel hub motor driving device of the electric vehicle and a working method of the electric vehicle. Background technique [0002] In recent years, the development of electric vehicles has made great progress, and the application of in-wheel motor drive devices as the core components of electric vehicles is also increasing. Among the currently commonly used hub motor drive devices for electric vehicles, some are non-circumferentially symmetrical in cross section, which affects the stability of the vehicle wheel rotation; flexibility; some structures are too complex, which affects the convenience and economy of automobile wheel tire disassembly and maintenance; the economics of electric vehicles. [0003] Chinese patent 201610100566.0 discloses a new energy vehicle hub motor powertrain drive system, including an axial and disc motor integrated machine, consis...
