[Auto Repair Knowledge]About car boneless wiper blades

1. The development of boneless wipers

The first since 1903carSince the birth of the wiper blade, people have been trying to make the traditional wiper blade better match the increasingly curved car windshield by combining the bead. The structure of the wiper blade is becoming more and more complex and precise. At the same time, higher requirements for use also call for the blade Technological changes... In the 1960s and 1970s, some manufacturers tried to cancel the bead structure and manufacture integrated scrapers, but due to the limitations of the material science at the time, the effect of the use of such scrapers was not ideal. At the end of the 1990s, technological progress made it possible to produce a new type of blade. The direct result of this technological change was the birth of a frameless blade (also called Aerotwin or beam blade abroad).
1. Because the traditional windshield wipers have multiple pressure points, they cannot adapt well to the curved windshield glass of modern cars. Then there will be some places where the wipers are not clean (there are water marks), and some places are scratched too hard ( There are scratches on the glass). And these places with high friction will produce noise.
2. Traditional windshield wipers usually use wind pressure to reduce wind resistance and wind noise (many Japanese and Korean cars even omit this). But doing so will have a bad effect on the vision.
3. Because of the complete elimination of movement jitter and wear, coupled with uniform force, anti-sun, simple structure and weight reduction, the service life of the motor and the wiper is longer than the traditional one.
This product has been widely used by European manufacturers in new high-end models, and is the second-generation wiper to replace traditional wipers in the future!
2. Advantages of boneless wiper:

1. The boneless wiper is closely attached to the curved glass and the force is evenly applied. The blade is coated with carbon film to ensure a quieter, smoother and cleaner scraping.
2. Designed by the principle of aerodynamics, the scraper will not be lifted by the air flow when the vehicle is running at high speed, ensuring a clearer wipe.
3. Optimized wiper structure design, the middle strip is flat and wide, which has the effect of sunshade and anti-aging.
4. Adopt non-framework floating steel sheet structure to eliminate movement shaking. Long life, light weight, and stronger adhesion than traditional wipers.
5. The rubber strip and the cover spring are all made of ozone and ultraviolet resistant rubber, which can adapt to different climatic conditions.
