Boneless wipers of
windshield wiper manufacturers encountered abnormal noise caused by rain and the solutions? When the driver presses the switch of the car wiper, the motor starts, and the speed of the motor drives the swing arm through the deceleration and torsion increase of the worm gear, the swing arm drives the four-bar linkage mechanism, and the four-bar linkage mechanism drives the left and right shafts installed on the front wall Swing, and finally the wiper blade is driven by the rotating shaft to sweep the windshield.
Reasons for the abnormal noise of the boneless wiper:
1. The windshield is large, and the wiper strip needs to be long to ensure that the clean area of the windshield is suitable, and there is only one vertical stress point for the boneless wiper. Therefore, it is difficult to ensure that the end does not tremble, and this tremor is an important factor for abnormal noise
2. Exhaust gas pollution, resulting in a lot of irregular-sized oil films on the glass surface that are not easy to see. The areas with oil films can be scraped smoothly, and the areas where there is no oil film will be very dry, and those oil films will become dirty after dust particles. Astringent, affecting the smoothness of the scraper on the glass
3. The aging blade will bend and harden to a certain extent, which is also an important factor causing sound. The aging wiper blade (because the vertical wiper arm pressure causes the blade deformation) to contact the glass. At this time, the deformed wiper blade, plus the irregular oil film on the glass that is not easy to remove, and other interference factors Directly As a result, the scraper will easily "jump" on the glass surface and then vibrate irregularly. The direct result is noise.
Boneless windshield wipers to solve the abnormal noise:
1. The windshield is large, and the wiper strip needs to be long to ensure that the clean area of the windshield is suitable, and there is only one vertical stress point for the boneless wiper. Therefore, it is difficult to ensure that the end tremor does not occur, and this tremor is an important factor for abnormal noise. For this, in addition to changing a car with a smaller windshield, a better way is to replace it with a bone wiper arm with more pressure. .
2. Exhaust gas pollution, resulting in a lot of irregular-sized oil films on the glass surface that are not easy to see. The areas with oil films can be scraped smoothly, and the areas where there is no oil film will be very dry, and those oil films will become dirty after dust particles. Astringency affects the smoothness of the wiper on the glass. In addition to changing to a better-environmental city life, frequent use of glass water can achieve a certain effect.
3. The aging blade will bend and harden to a certain extent, which is also an important factor causing sound. If you don't want to change the wiper, the better way is to lubricate the glass and let the wiper slide on the glass instead of rough scraping on the rugged 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.
