When the car is moving, these situations occur and the wipers need to be replaced

(1) When there are irregular water marks every time the wiper is used

(2) When the wiper has a screeching sound when in use

(3) When there is obvious leakage of the wiper

Common wipers can be divided into: bone-based wipers and boneless wipers

In terms of the cost of the whole cost, the cost of boneless wipers is much higher than that of boneless, so most luxury cars are already standard when they leave the factory

The difference between the two

The bone-based wiper converts a little force on the junction of the wiper arm into a multi-point force on the wiper through the conduction of the two-stage bracket. In this way, the downforce given by the wiper arm is evenly distributed to the wiper strip. The multi-point pressure distributed on the wiper strip acts on the steel bar on its inside, which in turn distributes the force more evenly to the rubber strip. Due to the large number of gaps in the external skeleton, the wipers will vibrate when high-speed air flows through. A small vibration will bring more noise, and a large vibration will make the entire wiper in an unstable state, and even a break, which will seriously affect the working efficiency of the wiper. On the other hand, the curved surface shape of the front windshield of the car is becoming more and more complex, and the fit of the wiper is more demanding, which makes the old guy with bone wiper a little powerless, often because of the uneven force of the rubber strip, resulting in the hanging water is not clean, and the wiper beats are noisy.

Compared with bone-based wipers, boneless wipers are very similar in structure to bone-based wipers, but in terms of the force of the wiper rubber strip, the two are completely different. Due to the use of thicker, thicker, wider, and better elastic steel, this boneless wiper can be divided without the skeleton structure on the bone-based wiper, and directly act on the steel sheet, so that the force concentrated at one point can be well dispersed, so that the skeleton can be removed, and the uniform force of the rubber strip can be maintained.
