Reasons for abnormal sound of boneless wipers
1. The windshield is large, and the wiper strip needs to be very long to ensure that the clean area of the windshield is suitable, and the vertical force point of the boneless wiper is only one. Therefore, it is difficult to ensure that the end does not vibrate, and this tremor is an important factor in abnormal sound.
2. Exhaust gas pollution leads to many irregular-sized oil films on the glass surface that are not easy to see. Where there is oil film, it will be smooth to scrape, and where there is no oil film, it will be very dry, and those oil films will become dust particles after they are stained. Astringent, affecting the smoothness of the blade on the glass
3. The aged scraper will be bent and hardened to a certain extent, which is also an important factor leading to sound. The aged hybrid wiper (because of the vertical pressure of the wiper arm, causing the wiper blade to deform) is in contact with the glass. The deformed wiper blade at this time, plus the irregular oil film on the glass that is not easy to remove, directly As a result, the scraper is very easy to "jump" on the glass surface and then vibrate irregularly, and the direct result is noise.
The solution to the abnormal sound of the boneless wiper
1. The windshield is large, and the wiper strip needs to be very long to ensure that the clean area of the windshield is suitable, and the vertical force point of the boneless wiper is only one. Therefore, it is difficult to ensure that the end does not vibrate, and this kind of vibration is an important factor for abnormal noise. For this one, in addition to changing a car with a smaller windshield, a better way is to replace it with a multi-point pressure bone wiper arm .
2. Exhaust gas pollution causes many irregular-sized oil films on the glass surface that are not easy to see. Where there is oil film, it will be smooth to scrape, and where there is no oil film, it will be very dry, and those oil films will become dust particles after they are stained. Astringent, affecting the smoothness of the scraper on the glass. In addition to changing the city life with a better environment, the frequent use of glass water can achieve a certain effect.
3. The aged scraper will be bent and hardened to a certain extent, which is also an important factor leading to sound. If you don't want to replace the blade, then a better way is to lubricate the glass and let the blade slide on the glass instead of rough scraping on the rough glass. Since it is a lubrication problem between the glass and the rubber, it is recommended to replace it with a new one "Soft" scraper.
