How Do Windshield Wiper Arms Work?
The windshield wiper arm is an integral part of the vehicle's wiper system, tasked with the mechanical movement required to keep the windshield clear. It connects the wiper motor to the wiper blades, allowing for the oscillating motion necessary to sweep the blades back and forth across the windshield. This movement is typically powered by the vehicle's electrical system, with the wiper motor providing the necessary torque to move the wiper arms.
Windshield wiper arms are designed with a pivot point that allows them to move in a semicircular arc. The arm's base is attached to the vehicle's wiper linkage, which is connected to the wiper motor. As the motor turns, it moves the linkage, which in turn moves the arm. The precise movement of the wiper arms ensures that the blades maintain consistent contact with the windshield, effectively removing water and debris.
To enhance the performance of windshield wiper arms, manufacturers often incorporate tension springs or adjustable mechanisms. These features help maintain the correct pressure on the windshield, ensuring that the wiper blades can effectively clean without streaking or missing spots. The combination of mechanical design and material strength makes the windshield wiper arm a crucial component in maintaining clear visibility for drivers.
