ELECTRIC WIPER AND WINDSHIELD WASHER SYSTEM

SYSTEM DESCRIPTION

The wiper is mainly consisted of the wiper motor assembly, the three-linkage mechanism,
and the pendulum rod and wiper blade with the tri-directional flexible ball joint. See figure
(wiper-1). The wiper motor is shown in figure (wiper-2).

Wiper

1. Permanent magnet DC motor
2. Worm-gear speed reducer
3. Wiper motor output shaft

Wiper motor（wiper-2）

The wiper motor is a speed reducer comprised of a mini permanent magnetic DC motor and a
worm-gear. In order to ensure that the pendulum rod and wiper blade could be positioned
under and parallel with low end of the front window each time after it has stopped. An
automatic stop conducting strip is installed on the back of the worm output shaft of the speed
reducer and 3 conducting contacts that contact with the conducting strip are installed on the
rear cover of the speed reducer. The strip and the contacts jointly perform the automatic stop
function together with the contact of the 0 position of wiper switch.

The washer is consisted of 5 parts which including a mini permanent magnet DC motor,
centrifugal water pump, nozzle, liquid storage container and water pipe. The motor and water
pump make up the assembly of the washer motor and the water pump as shown in figure
(Wiper-3):

1-Water inlet
2-Impeller blade
