The power input to the stator armature of the hub motor, as the handle is gradually pushed forward, the output voltage of the power battery increases, then the voltage of the stator armature of the hub motor increases, when the voltage of the armature increases, the motor torque will be When the motor armature voltage decreases, the armature current and the torque of the hub motor will decrease, which will cause the speed of the hub motor to decrease, so that the rotor of the hub motor rotates, connecting the hub motor to The electric wheel integrated with the wheel directly drives the forward rotation to make the electric vehicle move forward. The driver can control the forward speed of the electric vehicle according to the road conditions and the forward rotation angle of the handle; when the electric vehicle is to be controlled in reverse , the driver holds the handle of the handle-type steering rod and pushes it backwards, the handle drives the connecting rod and the rotating disc to rotate backwards, and the rotating disc drives the backward magnetic steel on the front outer wall to rotate, and the backward magnetic steel gradually and the backward linear Hall element (backward) The linear Hall element is a switch-type position sensor) approaching and inductively matching, and the magnetic field detected by the retreating linear Hall element is converted into an electromotive force output, and the switch-type position sensor converts the measured data, such as current, voltage, torque, etc. into The electrical signals are adjusted to appropriate values by connecting the digital controller in the circuit, and then input to the power converter. The power converter uses the data to adjust the energy flow between the power battery and the motor to control the hub motor. Speed, with the gradual increase of the induction area of the receding magnet and the receding linear Hall element, the magnetic field strength changes accordingly, and the electrical signal data of the switch-type position sensor is then input to the power converter, and the power converter converts the power according to the electrical signal data. The power supply of the battery is input to the stator armature of the hub motor. As the handle is gradually pushed back, the output voltage of the power battery increases. Then, the voltage of the stator armature of the hub motor increases. When the voltage of the armature increases, the motor torque increases. will increase, whereby the hub motor speed increases, conversely, when the motor armature voltage decreases , the armature current and the torque of the hub motor will decrease, which will cause the speed of the hub motor to decrease, and when the rotating disc rotates backward, the circular arc rib protruding from the outer wall of the rear side of the rotating disc rotates with it, and the circular arc rib rotates backward. In contact with the small roller, the protruding arc rib drives the small roller to rotate downward, the small roller drives one end of the pendulum rod to rotate downward, and the other end of the pendulum rod drives the lower contact to close with the upper contact, making the electric wheel hub The reverse rotation power supply of the motor is turned on, so that the rotor of the hub motor rotates in the reverse direction, and the electric wheel that integrates the hub motor and the wheel is directly driven to rotate in the reverse direction, so that the electric vehicle is driven in reverse. When the handle is pushed forward or backward, after people release the handle, the left and/or right outer wall of the rotating disc is connected with Under the action of restoring force, the torsion spring between the connecting bases drives the rotating disc to return to its original position, and under the action of the pulling force of the tension spring, the lower contact is disconnected from the upper contact.
