Talking aboutWiper, Many riders may disagree.existcarIn the sum, the wiper is a relatively small part. However, according to the International Driving Safety Survey: When driving in rain, the traffic accident rate caused by the aging of the wiper is about 5 times higher than usual. Summer is the rainy season. If your wiper is faulty, repair or replace it as soon as possible.
There are roughly two types of wipers. One is the traditional intermittent wiper, which is the most common wiper. There are three to four stages, which can be adjusted by the driver according to the rain and sight conditions; the other is the raindrop sensor. , In recent years, it has been mostly used in middle and high-end vehicles.A good wiper must have heat resistance, cold resistance, acid and alkali resistance, corrosion resistance, fit the windshield, reducemotorBurden, low noise, strong water repellency, soft and not scratching the windshield, etc., can make your vision clear. The maintenance personnel suggest that in order to ensure your driving safety, it is best to replace the wiper once a year.
1. First find out which type of wiper your car uses, you can refer to the manual that comes with the car to see the wiper model indicated above.
2. Pay attention to whether the way the support rod is connected to the wiper rocker arm is matched. Because some support arms are fixed to the rocker arm with screws, and some are locked with convex buckles.
3. Pull up the wiper and touch the cleaned rubber wiper with your fingers to check for damage and the elasticity of the rubber blade. If the blade is aging, hardened, and cracked, the wiper is unqualified.
4. During the test, set the wiperswitchPlace it at various speeds and check whether the wiper maintains a certain speed at different speeds. Especially in the intermittent working state, pay attention to whether the wiper maintains a certain speed when it is moving.
5. Check the state of the wiper, and whether the wiper rod has uneven swing or missed scraping. If the following three situations occur, the wiper is unqualified. The first is that the swing is not smooth and the wiper is abnormally beating; the second is that the contact surface of the rubber cannot be fully attached to the glass surface, resulting in wiping residue; the third is that the glass surface is in a water film state after wiping, and small stripes, fog, and fog are produced on the glass. Linear residue.
6. During the test, pay attention to whether the motor has abnormal noise, especially when the wiper motor "buzzes" and does not rotate. This shows that the mechanical transmission part of the wiper is rusty or stuck. At this time, the wiper switch should be turned off immediately to prevent the motor from being burned.
7. Some people think that the longer the length of the wiper blade, the larger the area of the wiper, and the better the field of vision. In fact, the wiper blade is not as long as possible. Although extending the length of the wiper blade can increase the visible range of the field of view, it will also increase the burden on the wiper motor and the wiper rod. Of course, it can be lengthened, but it must not hinder the normal operation of the wiper.
