Electric Motor and Worm Gear Reduction – The combination of the two give power to the windshield wipers.

Parts of Best Windshield Wipers

Windshield wipers consist of more than a few parts, like most systems in a vehicle. The main parts of a windshield wiper that makes it work perfectly are:

Windshield Wiper Internal Controls – You can find these particular controls on the core dashboard panel to the left side of the main dash display or the control arm protruding from the steering wheel.

The Windshield Wiper fluid pump, Tubes and Tanks – These are the components in charge of spraying out the windshield wiper fluid, giving drivers the opportunity to clean any grimy windshield.

Wiper Arm – This is the part that fixes the wiper blade to the wiper transmission, allowing for unimpeded movement over a big patch of the windshield.

Wiper Blades – This is the part of the windshield wipers that get rid of moisture from the windshield.

The Wiper Transmission – This is the part of the device that controls the movement of the wiper arm

Wiper Motor – Gives power to the fluid pump and wiper transmission

How Wiper Blades Work

Nowadays, vehicles come with an incredible piece of technology (wiper blades) that a lot of vehicle owners take for granted. Windshield wipers are an essential part of the vehicle that gives the people on board of a vehicle safety.

Windscreen blades have come a long way from the earlier handmade versions. The early blades made use of buttons or hand cranks located within the car. from the 1920s to 1960s, windscreen wipers were vacuum powered. The intermittent or blinking windshield wiper of these days was manufactured in the early 1960s.

How the device works are that it is moved by a motor sited at the pedestal of the window for clearing the window of rain, debris and other materials to make the driver see clearly. Windshield wipers can be programmed in more than a few ways, depending on the brand of vehicles.

Nearly all vehicles are with two wipers which move about in sync with one another, while other models have only one wiper that covers a wider swatch of the windscreen.

On the other hand, there are more than a few models of vehicles that have wipers on the back window. It is equally necessary to note that there are few older types of vehicles that have wiper blades located on their headlights.

This is part of the wiper that pivots at one end with a long blade attached to the other. The arm works with an electric motor, even though pneumatic power is also used in a number of vehicles. It works by swinging the blade to the front and back of the glass, sweeping rainfall off its surface.

You can easily adjust the speed, considering many incessant speeds and more sporadic settings. Most vehicles make use of two synchronized radial arms as a lot of commercial vehicles use two coordinated pantograph arms.

The Wiper Controls

There are many different types of controls or switches for wipers. Some of the vehicles have only one sporadic speed, others have ten discrete settings and yet, others have a sliding scale that you can set for nearly any time interval.

Whichever type of windshield controls you have in your vehicle, setting them right can be complicated. Set them very fast and the windshield gets dry and the wipers squeak or set them too slow and get your visibility blocked by raindrops.

The quantity of water striking the windshield changes as your vehicle increases its speed and slowing down will even compound this problem. To keep you’re your wipers functioning very well needs regular attention. The car manufacturers have finally conquered this problem with the rain-sensing wiper.

Rain-sensing Wipers

The automakers have tried in the past to either get rid of the wipers or to have their speed controlled automatically. Some of the schemes entail identifying the vibrations originated by applying special coatings that didn’t let drops to form, letting individual raindrops hit the windshield or even ultrasonically quivering the windshield to break up the droplets.


A small cam is fixed to the output shaft of the gear reduction. As the wiper motor evolves, this cam spins around. The cam is fixed to a lengthy rod and as the cam rotates it moves the rod back and forward. The lengthy rod is attached to a small rod that triggers the wiper blade on the driver’s side. Another lengthy rod conveys the force from the driver-side wiper blade to the passenger-side wiper blade.

The Automatic Windshield Wipers

These windscreen blades work without the intervention of the driver. They comprise of a wiper control module and a sensor. An infrared beam targets the windshield continually when the vehicle is working. The beam mirrors off the glass and strikes the sensor. On the other hand, when wetness lands on the windshield, it disrupts the infrared beam. As a result, it cannot get to the windshield, prompting the sensor and prompting the wiper control module to switch the wipers on.

For the system to work, drivers must activate automatic windshield wipers after turning on their vehicles. It is necessary to activate the system in order for the wipers not to turn in wrong situations. For instance, a permanent damage could happen to the wiper motors and windshield wiper blades if a sensor switches on the wipers to clean an ice-covered windshield or during a car wash.


The windshield wipers are particularly made to clear the windshield of your vehicle in harsh weather to aid visibility. Your safety and visibility can be compromised if all the components of this device are not working very well. The complete guide on how windshield wipers work will help you to understand your wipers and what to do when they are not working properly.
