The main role of the motor is to control the switch and tightness of the handbrake, including:
1. control switch : control the hand brake on and off by electrical signal.
2. adjust the tightness : adjust the tightness of the handbrake according to the need to achieve parking and parking functions.
The working principle of the handbrake execution motor is based on the principle of electromagnetism, and the specific steps are as follows:
1. magnetic field : When the power supply is energized to the motor, the coils in the motor will produce a magnetic field.
2. attracts the core : This magnetic field attracts the core in the handbrake, which releases the wheel.
3. power off : When the power is off, the magnetic field disappears, and the spring in the handbrake will pull the iron core back to its original position and tighten the wheel.
