The car wiper is also called wiper, wiper, wiper or windshield wiper. It is a part of the car. It is a device used to wipe off raindrops and dust attached to the windshield of the vehicle to improve the driver ’s performance. Visibility increases driving safety.
3 Segments Spoiler, fit for various curvatures, reduce wind lift, universal adapter fit for 70% cars, UL for left steer, UR for right steer.
Graphite coated rubber, minimized noise and chattering.
Wind bridge structure design, minimized water dragging.
The car wiper is composed of a motor, a reducer, a four-link mechanism, a wiper arm mandrel, and a wiper blade assembly. Its main function is to remove rain and snow and dust on the windshield that obstruct sight. The power source of the wiper is the electric motor, which is the core of the entire wiper system. The quality requirements for wiper motors are quite high. It uses a DC permanent magnet motor, and the wiper motor installed on the front windshield is generally integrated with the worm and worm mechanical part. The function of the worm gear and worm gear is to reduce the speed and increase the torque. The output shaft drives the four-link mechanism. The four-link mechanism changes the continuous rotary motion into a left-right swing motion.
The wiper motor uses a 3-brush structure to facilitate speed changes. The intermittent time is controlled by an intermittent relay, and the wiper wiper is wiped according to a certain period by using the charging and discharging functions of the return switch contacts of the motor and the resistance and capacitance of the relay. The wiper blade of the wiper is a tool to directly remove rain and dirt from the glass. The scraper rubber strip is pressed against the glass surface by the spring strip, and its lips must match the angle of the glass to achieve the required performance.
Classification Wiper is an important accessory installed on the windshield. Its role is to remove rain and snow and dust from the windshield that obstruct vision. Therefore, it plays an important role in driving safety.
Wipers can be divided into mechanical, vacuum, pneumatic, hydraulic and electric according to their driving methods. Modern cars generally use electric wipers, which have the advantages of simple structure and easy control.
The electric wiper is composed of a motor, a crank, a transmission rod, a wiper arm and a wiper blade. When the motor rotates, it drives the crank and the transmission rod to work, so that the scraping arm and the scraper swing on the glass. Modern wipers work in three ways: Intermittent wiper: Wiper every four seconds for drizzle. Low-speed wiper: for medium and light rain and snow High-speed wiper: for heavy rain and snow.
