wiper is an ordinary car part, but even such a small part, there are many questions. Whether it is structure, wiper style or interface style, there are many categories of wipers. Today, the Bull Cart Lab will talk to you about the mysteries of wipers.
1. According to the structure classification
1. Bone wiper
Bone wiper, as the name implies, is a "skeletal structure" on the wiper blade. In addition to the main wiper bracket, there is also a secondary bracket to support the wiper blade. Z1z
bone wipers were a relatively common form of wipers in the early years. They have been basically replaced by boneless wipers. Of course, bone wipers are still used in many low-end models.
Because the pressure points between the "bones" are average, the bone wipers are prone to friction noise with the windshield. In addition, because most modern cars use curved glass, the bone wipers cannot fit properly, so they are replaced one after another.
2. Boneless wiper
boneless wiper means that there is no "skeletal structure" on the wiper, but in fact an elastic steel sheet is hidden on the wiper, so that the wiper can be completely attached to the windshield.
The boneless wiper has a better fit to the curved glass, and the force is even, the brush hanging effect is better, and no noise is generated. Now most models have adopted the boneless wiper.
2. Classification according to the wiper type
1. Parallel wipers
can be divided into parallel wipers, split wipers and single wipers according to the wiper wiper types. The two windshield wipers of parallel windshield wipers adopt almost the same swing pattern, so they are called parallel windshield wipers.
Generally, the front windshield has a low height, and models with an aspect ratio higher than 0.7 will use parallel wipers. Its advantage is that the length of the wiper is short, so the load of the wiper motor is relatively lower and the cost is lower.
Since both wipers wipe to the driver's side, there will be a larger blind area above the passenger, which is the biggest disadvantage of parallel wipers.
2. Split windshield wipers
are generally used on coaches. This type of windshield wiper uses a symmetrical wiper direction, which wipes from the center to both sides of the windshield, so it is called a split windshield wiper. .
Generally, the windshield has a higher speed and an aspect ratio of less than 0.7 will use split wipers. Its advantage is that the blind area of the co-pilot area is small, but there will be a certain scratching blind area in the central part. The length of the wiper blade of
split-type wiper is longer, so a slightly higher power wiper motor is required, and the cost will be slightly higher.
3. Single wiper
models with a smaller windshield area will use a single wiper. The models that use a single wiper are basically two extremes, one is a very small miniature car, and the other is a cool sports car.
I believe that the most impressive model for single wipers is the early Beverly. Perhaps only the French would think of such an alternative front wiper design.
Current single wiper models generally use two connecting rods, which are twisted together to increase the wiper area. In fact, no matter which type of squeegee, it must reach 98% of the squeegee coverage directly in front of the driver and 80% of the squeegee coverage directly in front of the co-pilot.
3. According to the interface classification
According to the interface of the wiper, it can be divided into U-hook interface, plug-in interface and dovetail interface.
Among them, the U-shaped hook wiper is the most common wiper interface. The early bone wipers and some boneless wipers use this interface. This kind of interface installation is slightly complicated, and it is no longer the most mainstream installation interface.
It’s easier to replace other interfaces. For example, the plug-in interface often used in Volkswagens can be easily removed and installed by simply pressing the jack. Since
is easy to replace, there is a risk of being stolen, and for the sake of beauty, the wipers of many models are hidden under the cabin cover and cannot be lifted directly. When replacing, you need to enter the wiper repair mode. Entering the maintenance mode is generally to press and hold the wiper after the vehicle is powered offYou can check the actual instructions for specific models.
The above is a complete introduction to car wipers. I believe that according to the classification, you also have a very clear and in-depth understanding of the wipers of your car. Pay attention to the ox cart laboratory and take you to learn more about cars every day.
