Wipers power source from the motor, which is the core of the wiper system. Quality requirements wiper motor is very high. It uses DC permanent magnet motor, windshield wiper motor is mounted on the front glass on the mechanical parts are generally made with the worm body. The role of the worm body is decelerated by twisting its output shaft driven four-bar linkage, four-bar linkage by a continuous rotary motion from side to side movement for change.

  Wiper motor using three brush structure to facilitate the shift. Intermittent time by intermittent relay control, the use of electrical charge and discharge function return relay switch contact resistance and capacitance according to a certain period so that the wiper sweeps. Wiper blade strip is removed directly on the glass rain and dirt tools. Blade strips pressed by the spring strip to the glass surface, its lip angle must be aligned with the glass, so as to achieve the required performance.

  Under normal circumstances the combination switch in the car there wiper control knob handle with low speed, high speed, intermittent three stalls. Top handle is scrubber key switch, press the switch wash water spray, wash with windshield wipers. Car washing system is currently very common device, which consists of storage tanks, pumps, pipes, spray nozzle components. Wherein the tank is generally 1.5 liters to 2-liter plastic pot, electric water pump is a miniature pump, it will lose the washing water through the tank to the spray nozzle, after 2 to 4 spray nozzle squeezing action will wash water into small jets sprayed the windshield, with the wipers play a role in cleaning the windshield.
