1. Wiper motor works
wiper motor is driven by a motor, the rotational movement of the link mechanism by the motor is converted into reciprocating motion of the wiper arm, the wiper operation in order to achieve, in general ON motor, can make the wiper work by selecting a high-speed low-speed stage, the current size of the motor can be varied, thereby controlling the motor speed and thus the speed control wiper arm. 3 wiper motor using the brush structure to facilitate shifting. The intermittent pause time relay control, the charging and discharging function by the motor of the return relay switch contacts to make the resistance and capacitance of the wiper blade according to a certain cycle sweeps.
the rear end of the wiper motor are enclosed within a housing of the same small gear transmission, the rotational speed of the output is reduced to the desired speed. This device is commonly known as called wiper drive assembly. The wiper assembly connected to the output shaft end mechanical means, reciprocally swing the wiper is achieved by driving forks and spring return.
wiper blade rubber is a direct removal of rainwater and dirt on the glass of the tool. Pressed by the spring blade rubber strip to the glass surface, it must cooperate with the lip consistent performance, in order to achieve the desired angle of the glass. Generally there wiper control knob, with low speed, high speed, intermittent gear 3 on an automobile combination switch lever. Scrubber is the top handle push switch, press the switch discharge wash water, washed with windshield wiper.
wiper motor quality is very high. It uses a DC permanent magnet motor, mounted on the front windshield wiper motor on the glass is generally the worm wheel with the worm integrally formed mechanical parts. Action worm gear reduction by twisting is, an output shaft driven four-bar linkage, the four-bar linkage by a continuous rotational movement about the swing movement changes.
