Embodiment 1
[0017] Such as Figure 1 to Figure 7 Shown is an embodiment of the hub motor with forward and reverse speed change of the present invention. The electric vehicle transmission includes a hub ring 5, a box body 1 and related transmission mechanisms, and the box body 1 is fixedly connected to the motor 2 and the support shaft 11. , The fulcrum 11 is used to connect and fix the whole machine on the vehicle frame.
[0018] After the motor 2 is energized and rotated, the motor shaft gear 4 at the end of the motor shaft 3 meshes with the main shaft input gear 7 to rotate, and the main shaft input gear 7 rotates to drive the main shaft 8 to rotate.
[0019] Such as figure 1 As shown in , the first gear output gear 10A and the second gear output gear 10 are fixed on the output shaft 25, and the diameters and the number of teeth of the two output gears are different. The corresponding looper on the main shaft 8 has a second gear driving gear 9 meshing with the second gear output gear ...
