one of the wiper blade is standing car body attachment, its main function is used in the rain rain gear scraping the windscreen, is also used for washing the windshield, the environment provides a clear view for the driver, ensure safe driving.
1. The wiper blade type
common wiper blade is generally divided into two types, one is the traditional batch, which is the most common wiper blade, by the driver the rain and the situation in accordance with the line of sight to make adjustments; the other is the raindrop-sensing, multi-use in recent years on the senior models.
2. Features
The wiper blade must have good heat, cold, acid, corrosion resistance, can be bonded to the windscreen, to alleviate the burden on the motor, low noise, strong water-repellent, soft and so does not scratch the windshield can make your vision clear.
3. Wiper motor
power source from the motor of the wiper blade, the wiper blade which is the core of the system. Quality wiper blade motor is very high. It uses a DC permanent magnet motor, the wiper blade mounted on the front windshield glass is generally on the motor and the worm integrally formed mechanical part of the worm wheel.
Working principle: wiper motor is driven by the motor, the rotational motion of the link mechanism by the motor is converted into reciprocating motion of the wiper arm, in order to achieve the wiper operation, the motor is turned in general, to make the wiper work , by selecting a low gear a high speed, the motor current magnitude may be varied to control 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.
