1. during the low-speed gear, shift fork 10 stirs the terminal surface tooth meshing of terminal surface engaging gear 9 and low-speed gear input gear 5, 1 anticlockwise rotations of motor shaft, 1 terminal surface engaging gear 9 that drives the spline hookup of motor shaft rotates, terminal surface engaging gear 9 drives the synchronous anticlockwise rotation of low-speed gear input gear 5, low-speed gear input gear 5 drives low-speed gear dish gear 3 and 4 clockwise rotations of low-speed gear second grade input gear with 3 coaxial solid hookups of low-speed gear dish gear, 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 is gone forward. 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.
2. In a high-speed gear, the shifting fork 10 can shift the end face gear 9 to be separated from the end face teeth of the low-speed gear input gear 5, or the end face gear 9 and the end face teeth of the low-speed gear input gear 5 are always in a meshed state through the shifting fork 10 without any action; when the vehicle needs the high-speed gear to go ahead, motor shaft 1 drives down clockwise rotation at the motor, and motor shaft 1 drives high-speed gear input gear 6 clockwise rotation, 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 goes ahead. 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.
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 low-speed gear input gear 5's terminal surface tooth part, and output shaft 2 clockwise rotation under the reverse push wheel effect:
1) under the drive of the output shaft 2, the inner ring and the outer ring of the high-speed gear output gear 8 (which is set as a high-speed gear output one-way gear) rotate clockwise at the same time, and drive the high-speed gear input gear 6 meshed with the outer ring of the high-speed gear to rotate anticlockwise, and the high-speed gear input gear 6 and the motor shaft 1 are the same part which is coaxially and fixedly connected, so the motor shaft 1 also rotates anticlockwise.
2) Because low-speed gear output gear 7 (establish to low-speed gear output one-way gear) and high-speed gear output gear 8 inner circle output shaft 2 altogether, the unidirectional direction is arranged syntropy again, so the inner circle of low-speed gear output gear 7 also all rotates clockwise with the outer lane tooth, and drive low-speed gear second grade input gear 4 and rather than coaxial solid low-speed gear dish gear 3 anticlockwise rotation that allies oneself with, low-speed gear dish gear 3 drives low-speed gear input gear 5 clockwise rotation rather than the meshing again, because terminal surface gear 9 and low-speed gear input gear 5 terminal surface tooth have separated this moment, so low-speed gear input gear 5 slips the idle running on motor shaft 1. Therefore, when the reverse cart is carried out, the low gear and the high gear can normally rotate and are not interlocked, and the normal reverse cart can be realized by the structural device arranged in the mode.
Compared with the prior art, the two-gear speed change gear shift structure of the electric two-wheeled motorcycle with the reverse pushing function is simple, high-low two-gear quick gear shift of the electric two-wheeled motorcycle is facilitated, specifically, when low-speed gear shift is needed to move forward, the end face gear shift gear is shifted through the shifting fork to be meshed with the end face teeth of the low-speed gear input gear, the motor shaft drives the low-speed gear input gear to synchronously rotate anticlockwise through the end face gear shift gear, the low-speed gear input gear drives the coaxially fixedly connected low-speed gear disc gear and the low-speed gear secondary input gear to rotate clockwise, and the low-speed gear secondary input gear drives the output shaft to rotate anticlockwise through the low-speed gear output gear to transmit torque; when a high-speed gear needs to be shifted to move forwards, the shifting fork can shift the end face gear engaging gear and the end face teeth of the low-speed gear input gear to be separated or do no action, the motor shaft drives the high-speed gear input gear to rotate clockwise, and the high-speed gear input gear drives the output shaft to rotate anticlockwise through the high-speed gear output gear to transmit torque; meanwhile, when the cart is reversed, the low-speed gear and the high-speed gear can normally rotate and are not interlocked, so that the cart can be normally reversed by the structural device arranged in the form.
