1. during high-speed gear, shift fork 10 stirs the terminal surface tooth meshing of terminal surface engaging gear 9 with high-speed gear input gear 6, and motor shaft 1 clockwise rotation, motor shaft 1 drive spline-coupled terminal surface engaging gear 9 and rotate, and terminal surface engaging gear 9 drives the synchronous clockwise rotation of high-speed gear input gear 6, and high-speed gear input gear 6 drives high-speed gear output one-way gear 8 anticlockwise rotation, and high-speed gear output one-way gear 8 drives output shaft 2 anticlockwise rotation and spreads the moment of torsion, and the vehicle is gone forward. At this time, the outer ring teeth of the low-speed output one-way gear 7 are driven by the motor shaft 1 to rotate clockwise sequentially through the low-speed input gear 5, the low-speed dial gear 3 and the low-speed secondary input gear 4, the inner ring of the low-speed output one-way gear 7 is driven by the output shaft 2 to rotate anticlockwise, the inner ring and the outer ring of the low-speed output one-way gear 7 slip, and the low-speed does not output torque.
2. In a low-speed gear, the shifting fork 10 can shift the end face gear 9 to be separated from the end face teeth of the high-speed gear input gear 6, and also can not do any action, namely the end face gear 9 and the end face teeth of the high-speed gear input gear 6 are always in a meshed state through the shifting fork 10; when the vehicle needs the low-speed gear to move ahead, motor shaft 1 anticlockwise rotates under the motor drives, motor shaft 1 drives low-speed gear dish gear 3 and 4 clockwise rotations of low-speed gear second grade input gear who connects firmly with the low-speed gear dish gear 3 is coaxial through low-speed gear input gear 5, low-speed gear second grade input gear 4 drives 7 anticlockwise rotations rather than the engaged low-speed gear output one-way gear, low-speed gear output one-way gear 7 drives output shaft 2 anticlockwise rotation and spreads the moment of torsion, the vehicle moves ahead. At this time, the inner ring of the high-speed gear output one-way gear 8 rotates counterclockwise under the driving of the output shaft 2, the outer ring of the high-speed gear output one-way gear 8 rotates clockwise under the driving of the high-speed gear input gear 6 meshed with the high-speed gear output one-way gear 8, the inner ring and the outer ring of the high-speed gear output one-way gear 8 are in a slipping state, and the high-speed gear does not output torque.
3. When reversing the shallow, terminal surface engage gear 9 is stirred to shift fork 10, lets terminal surface engage gear 9's terminal surface tooth and high-speed gear input gear 6's terminal surface tooth part, and output shaft 2 clockwise rotation under the reverse push wheel effect:
