The wiper control of the Volkswagen Polo has a knob for controlling the rear wiper. By twisting the head of the control button and slowly lifting it upward, you can turn off the rear wiper. Here is some related information: 1. Structure: The car wiper is a four-bar linkage mechanism, divided into front and rear wipers. It consists of a motor, reducer, four-bar linkage mechanism, wiper arm spindle, wiper blade assembly, etc. 2. Main function: The main function is to remove rain, snow, and dust that obstruct the view on the windshield. 3. Working principle: The power source of the wiper comes from the motor, which is the core of the entire wiper system. The wiper uses a DC permanent magnet motor, and the wiper motor installed on the front windshield is generally integrated with the worm gear mechanical part. The worm gear mechanism is used to reduce speed and increase torque, and its output shaft drives the four-bar linkage mechanism, which converts continuous rotational motion into left-right swinging motion.
