How to Use the Windshield Wipers on a Car?

[StephanieAnn]

Here are the steps to use the windshield wipers on a car: 1. There is a wiper control knob on the car's combination switch handle, which has three settings: low speed, high speed, and intermittent. 2. At the top of the handle is the washer button switch; pressing it will spray washer fluid. 3. Use the wipers in conjunction with the washer to clean the windshield. The principle of the wiper system is: The power source for the wipers comes from an electric motor, which is the core of the entire wiper system. It uses a DC permanent magnet motor, and the wiper motor installed on the front windshield is typically integrated with the worm gear mechanical part. The worm gear mechanism serves to reduce speed and increase torque, with its output shaft driving a four-bar linkage mechanism. This mechanism converts continuous rotational motion into a left-right oscillating movement.
