[0002] At present, electric vehicles have entered thousands of households as a green and environmentally friendly means of transportation. During daily use, electric vehicles inevitably alternately drive on flat roads and steep roads. For steep roads in mountainous areas, electric vehicle motors with less power often It seems powerless, and the drive structure of the existing gear motor leads to excessive energy consumption, which cannot meet the daily needs of people in mountainous areas;

Embodiment
[0017] Embodiment: the self-induction clutch 6 works in combination with the motor and the reducer 5, the inner motor is powered by the battery of the electric vehicle, the stator coil 12 is energized so that the rotor 8 drives the inner housing to rotate on the main shaft 4, and passes through the inner housing left 9 and the outer housing The self-induction clutch 6 connected to the left end cover 2 and the reducer 5 cooperate to drive the outer shell to rotate on the main shaft 4; When the pressure plate 601 of the self-induction clutch 6 and the clutch plate 602 are separated, the self-induction clutch 6 is in a tight state. At this time, the inner shell drives the outer shell to rotate synchronously through the self-induction clutch 8. The reducer does not work alone, and also rotates synchronously with the motor. In the above process, the main rod of the separation rod 607 is in contact with the cone 606h and slides at the low position of the cone 606h. This is the initia...

The invention provides a self-induction clutch of an automatic speed changing hub motor for an electric vehicle. On the basis of an original clutch, a disengaging rod is improved according to the lever principle, and under the driving of external force, a clutch plate and a platen are fastened and disengaged by the disengaging rod; an automatic induction bracket and a self-disengaging inductor are additionally arranged to serve as inductors of exogenic action and are matched with the disengaging rod to finish the corresponding action; the self-disengaging inductor is combined with the original clutch by virtue of the automatic induction bracket; power difference is formed according to respective rotation states, a limit spring is compressed by virtue of the power difference so as to change the sliding position of one end of a support rod on a cone, the cone is in a high position so as to extrude a main rod, and the main rod drives a driven disc to be disengaged from the platen; and vice versa, automatic disengaging and fastening effects are realized. The self-induction clutch is applied to a motor and is matched with a speed reducer to finish an automatic speed changing effect.
Description
technical field [0001] The invention relates to a self-induction clutch of an automatic variable speed wheel hub motor of an electric vehicle. Background technique [0002] At present, electric vehicles have entered thousands of households as a green and environmentally friendly means of transportation. During daily use, electric vehicles inevitably alternately drive on flat roads and steep roads. For steep roads in mountainous areas, electric vehicle motors with less power often It seems powerless, and the drive structure of the existing gear motor leads to excessive energy consumption, which cannot meet the daily needs of people in mountainous areas; [0003] Therefore, the clutch and the motor in the existing electric vehicle motor are improved, the torque is increased, and the power and climbing ability of the electric vehicle motor are improved. At the same time, the current required by the motor is low, which prolongs the mileage of the electric vehicle and improves th...
