Problems solved by technology
The structure of the electric vehicle shifting motor mentioned above is complex, production and assembly are difficult, and the manufacturing cost is high.
The motor is connected with the shifting mechanism. When the motor is working, it will drive some movable parts in the shifting mechanism to move. These movable parts will inevitably have some mechanical friction during the movement, thereby reducing the motor's power utilization

Embodiment Construction
[0024] The electric vehicle motor transmission device of the present invention is located between the motor rotor 3 and the wheel hub 5, the motor includes a stator 6 and a rotor 3, the stator 6 is fixed on the wheel shaft 4 of the wheel, and the rotor 3 and the wheel hub 5 are rotatably sleeved on the On the wheel shaft 4 , a rolling bearing 7 is arranged between the rotor 3 and the wheel hub 5 and the wheel shaft 4 .
[0025] A non-contact and inductive transmission structure is provided between the hub 5 and the rotor 3. The transmission structure is a split structure, including a permanent magnet 2 and an induction body 1. The induction body 1 is made of magnetic and conductive materials. There is a space between the induction body 1 and the permanent magnet 2, and the space between them can be as small as millimeters. When the transmission structure participates in the transmission between the rotor 3 and the hub 5, the permanent magnet 2 and the induction body 1 will not...
