The reason for the abnormal sound 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, while the boneless wiper has only one vertical stress point. Therefore, it is difficult to ensure that there is no tremor at the end, and this tremor is an important factor of abnormal noise

2. Exhaust pollution leads to many irregular oil films that are not easy to see on the glass surface. The places with oil films are smooth to scrape, while the places without them are dry and astringent. Those oil films will also become astringent after being stained with dust particles, affect the smoothness of the blade on the glass

3. The aging blade will bend to a certain extent and become hard, which is also an important factor leading to sound production. The aging wiper blade (due to the pressure of the wiper arm on the vertical side, causing the blade to deform) is in contact with the glass. The deformed wiper blade at this time, coupled with the irregular oil film on the glass that is not easy to remove and other interference factors It directly causes the blade 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 long to ensure that the clean area of the windshield is suitable, while the boneless wiper has only one vertical force point. Therefore, it is difficult to ensure that there is no tremor at the end, and this tremor is an important factor for abnormal noise. For this one, besides changing a car with a smaller wind gear, a better way is to replace it with a bone wiper arm with more pressure.

2. Exhaust pollution leads to many irregular oil films on the glass surface that are not easy to see. Where there is oil film, it will be smooth to scrape, while where there is no oil film, it will become dry. However, the oil film will become astringent after being stained with dust particles, which will affect the smoothness of the blade on the glass. In addition to changing to a better city life, frequent use of glass water can achieve certain effects.

3. The aging blade will bend to a certain extent and become hard, which is also an important factor leading to sound production. If you don't want to change the blade, then the better way is to lubricate the glass and let the blade slide on the glass instead of rudely scraping on the rugged glass. Since it is a lubrication problem between glass and rubber, it is recommended to change the new "soft" blade.
