wipers

Wipers, short for windshield wipers, are devices designed to clear rain, snow, and debris from a vehicle’s windshield to maintain visibility for the driver. They are commonly fitted on cars, trucks, buses, and many aircraft and marine vessels. Wipers are part of the vehicle’s exterior systems and are operated by the driver, with some models including automatic rain-sensing features that adjust speed.

A typical wiper system comprises a motor, a linkage or linkage-free mechanism, a wiper arm, and a blade assembly. The blade is made of rubber or silicone and is held against the glass by a frame or by a flexible beam. The blades sweep across the windshield in a controlled arc, pushed by the arm, and returned to their resting position when not in use. Advanced designs include beam blades, hybrid or frameless blades, and aero wipers that maintain contact at high speeds and under varying wind pressures.

Wiper blades are available in different configurations. Traditional framed blades have a metal or plastic frame that supports a flexible rubber blade. Beam and hybrid blades use a tensioned central beam for even pressure along the blade. Frameless designs rely on no external frame and use a curved, continuous blade. The choice of blade affects contact, noise, durability, and performance in cold or icy conditions.

Maintenance involves regular inspection and timely replacement of blades and arms. Common signs of wear are streaking, skipping, splitting, or squeaking. Replacements are typically needed every 6 to 12 months, depending on climate, usage, and blade quality. Cleaning the windshield and ensuring proper blade contact helps preserve effectiveness.
