Gear Motor Solution for Automobile Wiper

About Automobile Wiper

In almost every modern car, the windshield has a wiper, and these wipers have a battery-driven electric wiper water pump. The function of the water pump is to spray water on the main windshield to prevent dirt. Once sprayed, the windshield wiper can wipe the dirty water to one side. One can find such water pumps in the front hood of the car near the windshield, although their location may be different in some vehicles.

Today, vehicles have more than one wiper pump, one for the front windshield and another for the rear windshield. Some cars even have wiper pumps for the headlights that are sturdy, durable, and waterproof to a certain extent. They are usually operated from the passenger compartment, and their controls are located around the main steering wheel. Usually, the switch is located on the joystick next to the steering wheel.

Under normal circumstances, there is a wiper control knob on the handle of the automobile combination switch, with three gears of low Speed, high Speed, and intermittent. At the top of the handle is the washer button switch. When we press the switch, washing water is sprayed out, and the windshield is washed with the wiper. The scrubber system is a popular device on the car. It consists of a water storage tank, a water pump, a water pipe, and a water spray nozzle.

The water storage tank is generally a plastic tank of 1.5 liters to 2 liters, and the water pump is a miniature electric centrifugal pump, which transfers the washing water from the storage tank to the spray nozzles. The washing water is divided into small jets and sprayed to the windshield, which cooperates with the wiper to clean the windshield.

The World Principle of Automobile Wiper

The automobile wiper pump is composed of a motor, a reducer, a four-bar linkage, a wiper arm spindle, a wiper blade assembly, etc. The function is to remove rain, snow, and dust on the windshield that obstruct the line of sight. When the car wiper pump is working, you only need to turn on the switch, and it will send a signal to the control module. The control module has an automatic relay and can be used with the wiper water pump, which pumps the washing liquid through the pipe to the windshield through the washing nozzle. These pumps are usually driven by 12V motors and are of the DC type.
