Operation principle
The power source of the wiper comes from the motor, which is the core of the entire wiper system. The quality requirements of the wiper motor are quite high. It uses a DC permanent magnet motor, and the wiper motor mounted on the front gear glass is generally integrated with the worm gear mechanical part. The role of the worm gear mechanism is the slowdown torsion, and its output shaft drives the four-link mechanism, and the continuous rotational motion is changed to the movement of the left and right swing by the four-link mechanism.
The wiper motor uses a 3 brush structure to facilitate shifting. The intermittent time is controlled by intermittent relay, and the return and discharge function of the reactor resistance capacitor is screened according to a certain cycle using the charge and discharge function of the retractor resistance capacitor. The wiper's scraper strip is a tool that directly removes rain and dirt on the glass. The scraper strip is pressed toward the glass by the spring strip, and its lip must be coordinated with the glass angle, and can meet the desired performance.
In general, there is a wiper control twisting on the car combination switch handle, with a low speed, high speed, and intermittent 3 gear. The top of the handle is the scrubber button switch, press the switch with wash water, and the wind glass is washed with the wiper. The scrubber system is a very common device on the automobile, which consists of a water storage tank, a water pump, a water pipe, and a water jet. Among them, the water storage tank is typically 1.5 liters of plastic cans, and the water pump is a micro-electric centrifugal pump that transmits the water storage tank to the water spray mouth, and the extrusion of 2 ~ 4 spray mouth will be Washing water is divided into a small jet spray gear glass, and the wiper functions as a cleaning of the wind glass.
User Manual
Features Factors The Water Wiper of the rubber can maintain sufficient humidity. Only enough wettability can have very good toughness to keep the tightness of the window glass.
Very simple truth, a rice dried in a bowl, if you don't make it soft, don't say the dishwash, just use hardware to scrape, you can't scrape. The use of the wiper is also the case. Many riders often complain that the wiper is unclean, just did not understand this truth.
Using
wiper, wiper, as the name suggests, is used to scratch and rain, not used to scrape "mud".
so properly uses the wiper, not only the life of the wiper is not only the life of the wiper (a few wiper values can't be a few money), but the key is to effectively maintain a good line of sight, more beneficial for driving safety. I want to clear the above two basic points, I generally know the correct usage of the wiper.
Maintenance attention
So there is no car in the garage, should be developed every morning, rubbed a habit of the front window with the wet cloth.
One night, the wiper is dry, I want to use the wiper when you use the wiper, the gray on the front window, such dry grinding, not only hard to achieve good results, it is easy Damage to the wiper. The correct way is: After the wet cloth is finished, the small six sprinkle is shaved once. Because authentic wash glass is volatile, it can quickly let the window dry, thereby avoiding moistive glass absorbing mud.
There is a garage of the riders, should develop the habit of cleaning up a clean front window when returning to the garage every night.
, especially from the rain, the water droplets on the front window, the second after drying into water stains, then participate in the dust, the front window is hard to scratch . If the first day, take the wet wiper and dish the front window clean. The next morning, it can be very easy and clean.
On the way, when you drop the rain, don't hurry to open the wiper.
At this time, the water on the front window is insufficient, and the wiper is dry scraping, which only produces the effects of an appropriate. The pudding of the scratch on the front window is still difficult to scratch. If the rain point is very slow, it does not affect the sight, it is best to wait for the rain point in the front window and then start scratch. The wiper began in the rain, it is best to let the small six-shot glass water after the glass is scraped (spraying glass, not only when parking, not only on the way, it can be used on the way). To ensure that there is enough moisture on the front window to warm the wiper.
The wiper is preferably used for the second gear, and the continuous return is scraped.
Some riders like to use the intermittent mode when they like light rain, which is not very good. Driving on the road, not only the rain on the sky, but also better preparation of mud water splashes. In this case, the batch mode is easy to scrape the front window into a mud pattern, which seriously affects the sight.
on the road is stopped, don't rush to turn off the wiper.
The truth is the same, waiting for the front window to be full of mud ideas, and then rush to open the wiper, then become a scraper.
Maintenance Precautions
1. Regularly check the wiper blade. When it is found that the wiper blade is seriously worn or dirty, it should be replaced or cleaned in time, otherwise the work performance of the wiper will be reduced, affecting the driver's sight. When cleaning the wiper blade, you can easily remove the dirt on the blade with a cotton yarn with alcohol cleaner
. The blade is not available to gasoline cleaning and soaking, otherwise the blade will deform and affect its work. 2. When the wiper works, the windshield should be used first, otherwise it will scratch the glass, and due to the large friction resistance of the blade, the blade or burnout motor may be damaged. After opening the wiper switch, it should be noted that the motor has no abnum, especially when the wiper motor "嗡" does not rotate, indicating that the mechanical transmission portion has been rusted or caught, should immediately close the wiper switch to prevent burning Motor.
3. After the wiper scraping switch is closed in use, the wiper blade should return to the lower side of the windshield to stop. If the stop position is wrong, adjust it. When adjusting, the cover of the automatic stop can be turned, the stopping stop position is shortened clockwise, and the counterclockwise rotation is stopped.
4. When using the wiper in winter, if its scrape is free to hold or be snapped with a snow group, it should be closed immediately, clear the ice, and the snow group will continue to use, otherwise it will be too large to be too large and burn the motor.
5. Don't remove the motor freely. If you need to remove the motor due to the failure, don't drop the motor, collide. Because the wiper motor mostly utilizes permanent magnet DC motor, the magnetic pole uses ceramic material, which is easily damaged.
6. The wiper motor is more enclosed and cannot be disassembled. When you must be dismantled, you should keep inside to clear, and the contams such as iron filings are not allowed to fall into it; the felt to the oil-containing bearing is less lubricating oil, and the grease in the reducer is replaced.
Other related
In addition to the front windshield windshield, many passenger cars also devices after the glass window wiper, the driver can see the things behind the car rainy day. Some advanced passenger cars also have a cleaning device similar to a wiper. The rear glass window wiper and the head-absorbing lamp cleaning device do not have a special four-link mechanism, and only a compact converter (such as a rack gear or four-link mechanism) is attached to the motor, and the spin is changed to swing. According to the European and American regulations, when the lamp dirty and dirty to illuminate to 20%, the headlight cleaning device shall wash clean dirt in 8 seconds to restore the illumination to 80%. The aforementioned lamp wash water is provided by the windshield wiper water storage tank, and the position of the inlet nozzle is reasonable to make the vehicle can spray the wash water onto the lamp surface at any speed.
Wiper Cleaning
If the windshield is still not clean or working after using the windshield cleaning, it may be on the windshield or the wiper Wax or other substances. Clean the outer surface of the windshield with cleaning liquid or mild cleaning agent. If it is cleaned with water. No longer forming a water droplet. If the windshield has been clean.
wipe the rain blade by wipeling the wipes in the cleaning liquid or mild cleaners. Then use the water to wash the rain blade. If you clean the wiper and use the wiper. The windshield is still not Cleaning. Please replace the wiper blade.
Wiper maintenance
Due to the wiper strip, a small amount of preventing waxy wax is added during the manufacturing process, in the first time I use the rain Before, with a soft cloth dipped a small woven window to the wiper strip "scrape" several times to wash away the wax of its surface. Because any oily substances of windshield and "scraping" surface increase scraping resistance, reduce the scraping of scraping. Of course, the "scraping" of the wiper is not a big success, because the fine substances such as dust in the air and the exhaust of the vehicle exhaust gas will be attached to the windshield and the blade, increase the friction when scraping. At the same time, if a large amount of dust is attached to the surface of "scraping", it will also reduce its flexibility and affect the service life.
In addition to "scraping tongue", everyday use of wiper should also "have something wrong". When the window glass is dry or there is an obstacle, including snow, icing, mud block, hard bird feces, do not use the rain, otherwise the rain scraper, wiper motor and glass will be damaged. Similarly, before the cold weather in winter, the wiper should be checked in the window, if the windshield is hot, please open the windshield heating function, ensure that the windshield between the front and rear windshields and the blade can be used normally . In addition, winter ice and snow weather, if there is a wiper strip, if there is a piece of ice, there is a hardening, hindering normal flipping, it is also necessary to heat the ice sheet on the blade by windows. The elasticity of scraping tongue.
Wiper Replacement
Wiper Replacement Three Steps: Check, Select, Replacement and Installation Easily Get the Replacement of Wheed Wiper, Installing Methods.
First step: Whether the wiper is replaced
to determine if the wiper blade needs to be replaced, that is, when the rain is used, if you find There are noise or have a longer bar, affecting the field, so the rain has problems. When the rain is checked, the owner should first observe whether the wiper itself is broken, crack, rust, rubber hardening. If the wiper is found to have foreign matter, or leave a spotted slice after wiped glass, the owner can first clean the windshield and cleaning the wiper edge, and if the above symptoms are found, they need to be replaced. In general, if the wiper rubber deformed and stent deformation, there is a need to instantly replace the new wiper.
Step 2: Water wiper purchase
The type of wiper piece is not a lot, but there is also a model, how to choose a suitable Water wiper? Car wiper is scaled: swing arm, bracket, connection arms, bracket installation cartoon and strip total four parts, and three types of hooks, plugs and screws. The wiper size of the general family sedan is between 19 inch to 21 inches. There are many wins that can be chosen in the auto parts market. If you don't know the specific model of your car, you can refer to the car manual to see the wiper model indicated above, you can also open the car to the auto parts market, so that the merchant will help you choose.
Step 3: Waterfinder Replacement
Finally, it is time to replace, when replacing, only need to pull out the connection of the car, find The swing arm and the bracket are installed, and the old rain will be dispensed first, and then install the new wiper to the swing arm, and then go back, so that it is very good. After installing new rain, it is best to check and confirm, prevent inappropriate places or problems, affecting post-use, such as checking if there is shaking, abnormal sound, etc., once found, it is necessary to solve it in time.
Selection method
Starting the wiper, many riders may not be intentionally. In the sum of the car, the wiper is a relatively small component. However, according to the international driving safety survey showed that rainy days, the traffic accident rate caused by the aging of the wiper is about 5 times higher than that of usual. If your wiper is there, you have to fix or replace it. There are two kinds of wiper, one is traditional intermittent , this is the most common wiper, there are three sections of four paragraphs, which are adjusted by the driver according to the rain and sight conditions; One is raindrops induction , mostly used in the middle and advanced models. Good wiper must have heat resistance, cold resistance, acid and alkali resistance, resistance, can carry the windshield, reduce the burden of the motor, low noise, strong water, soft, soft, windshield, etc., can make you vision Clear. Maintenance personnel suggest that in order to ensure your driving safety, the wiper is best replaced once a year.
1, first understand which specification of the wiper for your car, you can refer to the car manual to see the wiper model indicated above.
2, pay attention to whether the strut is connected to the wiper rocker arm. Because some of the arm is fixed to the rocker arm with a screw, some is locked by a convex.
3, pull the wiper, touch the rubber rain brush with your fingers, check if it is damaged and the elasticity of the rubber blade. If the blade is aging, hardening, cracking, this wiper is unqualified.
4, in the test, place the wiper switch in various speed positions, check whether the wiper wiper in different speeds maintains a certain speed. Especially in the interruption operation, you should pay attention to whether the wiper keeps a certain speed during exercise.
5, check the wiper state, and whether there is a phenomenon in which the wiper strip has oscillating is uneven or leaking. If there are three situations, this wiper is unqualified. First, the swing is not smooth, the wiper is not jumped properly; the second is that the contact surface of the rubber cannot be completely bonded to the glass surface, and the wiping remains; the three is to show a water film in the glass surface, and a small stripe, fog and in the glass. Linear residue.
6, it should be noted that there is no abnormal noise in the motor, especially should be noted that when the wiper motor "嗡" does not rotate. This shows that the wheeler mechanical transmission part has a place where rusted or stuck, and should immediately close the wiper switch to prevent the motor.
7, some people believe that the longer the length of the wiper, the larger the area of the brush, the better the field of view. In fact, the wiper tablets are not, the longer the better. Although the length of the lean wiper can increase the range visible range, the burdener of the wiper motor and the wiper will also be increased relatively. Of course, it is necessary to extend, but to ensure that the normal work of the wiper must not be hindered.
