[0019] Example: see figure 1 , the whole system is composed of two sets of subsystems connected in series, the first subsystem is a 2K-H planetary gear transmission system, and the overall structure is a single-row planetary layout, which are: motor 1 and motor output shaft I, front sun gear 2. The front planetary gear 3, the front planet carrier 4, and the front ring gear 5; the front sun gear 2 is installed on the motor output shaft I through a spline (the motor output shaft is also the axle of the front sun gear), and the sun gear The planetary gears 3 meshed with the wheels are supported on the front row planetary carrier 4 through bearings, and the front row ring gear 5 is fixed on the case and meshed with the front row planetary gears 3 .
[0020] The second subsystem is also a 2K-H planetary gear transmission system, which is a single-row planetary layout, which are: rear sun gear 6, rear planetary gear 7, rear planetary carrier H and rear ring gear 8; The sun gear 6 i...
