There are two most common types of wipers, one is a parallel wiper (ie, the left and right synchronous wiper), and the other is a split wiper (ie, the left and right cross wipes).
The biggest feature of the parallel wiper is that it can use a slightly shorter wiper strip (our common co-pilot wipers are relatively short), and can also be equipped with a slightly smaller wiper motor, so most of these wipers are more economical. The disadvantage of parallel wipers is that the wiper on the front passenger seat is short, so when wiping, the upper right corner of the front passenger seat is more prone to blind spots.
Compared with the normal wiper, the split-type wiper has a longer linkage mechanism than the parallel wiper and requires a larger space for the flow groove to install, so the cost is generally higher than that of the parallel wiper. In addition, the coverage area of the front passenger seat of the split wiper is also larger than that of the parallel wiper, and relatively speaking, there is not such a large blind spot. However, the split-type wipers are more prone to water hanging in the middle of the front windshield, affecting the line of sight.
So, since the cost of split wipers is relatively high, can it be said that parallel wipers are all "cheaps", and split wipers are high-end goods? In fact, this is not the case, parallel wipers are good, split wipers Whether the wiper is good, it needs to be achieved in accordance with the regulations: 98% of the wiper coverage in front of the driver, and 80% of the wiper coverage in front of the co-pilot. As for which wiper method to choose, it has a lot to do with the shape of the front windshield.
On the premise of meeting the coverage rate, car manufacturers can choose which wiper method to use according to the design and positioning of their own models. As for which wiper method is better, we can't compare it with a quantifier. We all decide whether to replace the wiper according to the usage environment of our own vehicle, so comparing the two, no one is more durable than the other.
A few knowledge points about wipers
1. The original car has a bone wiper, can it be replaced without a bone?
If the original car has a bone wiper, it can be replaced with a boneless wiper. But it should be noted that it depends on the pressure of the wiper bracket of the model. For example, the pressure of the wiper bracket of some Japanese cars is relatively low. If a boneless wiper is used, the wiper may be unclear for a long time.
If this happens, it is recommended to use the traditional bone wiper; if the pressure of the bracket is large, the wiper strip can be pressed against the glass surface, so that the effect of the boneless wiper can be better reflected.
2. What's the matter with the wiper upright?
In the hot summer season or on days of heavy snow, we often see that the wipers of many vehicles are erected. What is going on? It turns out that at noon in the midsummer, the surface of the front windshield of the car The temperature can be as high as 50 degrees. If the wiper is exposed to the sun for a long time, it may cause the wiper rubber to deform. In winter, erect the wipers to prevent the wipers from freezing on the front windshield.
3. Is the way to polish the wiper reliable?
The method of refurbishing the wiper by grinding the wiper is reliable, but it is very particular about the technique. If the grinding is too violent, or the type of sandpaper is selected incorrectly, it is easy to deform the shape and surface of the edge of the rubber strip. Not worth the loss.
