When the car is running, these situations occur and the wiper needs to be replaced

① When there is irregular water mark every time the wiper is used

② When the wiper appears harsh squeaking sound in use

③ When the wiper appears obvious leakage phenomenon

Common wipers can be divided into bone wipers and boneless wipers

And in terms of the cost of the whole construction, the cost of boneless wiper is much higher than that of bone, so most luxury cars have been standard when they leave the factory

The difference between the two

Bone wipers transfer one force on the wiper arm connection point to more force on the wiper through the conduction of the two-stage bracket. So that the wiper arm to the down pressure, evenly distributed to the wiper strip. The multi-point pressure distributed on the wiper strip acts on the steel strip inside, which in turn distributes the force more evenly on the rubber strip. Because of the external skeleton gap, high-speed airflow through, will lead to wiper vibration. Small vibration will bring more noise, and large vibration, will let the whole wiper in an unstable state, and even appear to rush the situation, seriously affect the work efficiency of the wiper. On the other hand, the curved shape of the front windshield of the car is becoming more and more complex, and the fit degree of the wiper is higher, which makes the old guy with bone wiper feel inadequate. Often, because of the uneven force of the rubber strip, the hanging water is not clean, and the wiper beats with noise.

Compared to bone wipers, boneless wipers are very similar in structure to bone wipers, but in terms of the force on the wiper strip, the two are quite different. Due to the use of thicker thickness, wider width and better elasticity of steel, the boneless wiper can do not need to have the skeleton structure of the bone wiper for force, direct force on the steel sheet, can concentrate on a point of force is well dispersed, so that you can remove the skeleton, and maintain the uniform force of the rubber strip.
