Wipers, also known as wipers, wipers, wipers or windshield wipers, are devices used to wipe off raindrops and dust attached to the windshield of a vehicle to improve driver visibility and increase driving safety. Because of legal requirements, cars are equipped with wipers almost everywhere. The rear windows of vehicles such as hatchbacks and RVs are also equipped with wipers. In addition to cars, other means of transportation are also equipped with wipers, such as trains and trams. Some engineering tools, such as cranes, are also equipped with wipers.
The wiper scientific name refers to the sheet structure installed in front of the windshield. It is composed of a motor, a reducer, a four-link mechanism, a wiper arm spindle, and a wiper blade assembly. Its main function is to wipe out the gear. Rain and snow and dust on the windshield that obstructs vision.
The intermittent flexible wiper is adjusted by the driver according to the rain and sight conditions. Unlike other wipers installed on ordinary cars, it can automatically increase and decrease the wiper speed according to changes in vehicle speed. Because in the same amount of rainfall, the faster the speed of the vehicle, the more rain will come, and if the vehicle is stopped, the deceleration of the wiper will reduce the noise.
The wiper combines two mechanical technologies: First, the wiper is powered by a motor and a reduction worm gear. Second, the wiper is driven by the motor through the link mechanism.
Windshield wipers can be found on car windshields, some car headlights, airplanes and even spacecraft.
