Why are car wipers so fragile?

The usage rate of car wipers is very high. Moreover, with the rapid development of today's society, air pollution is becoming more and more serious, as long as the car is exposed to the outside world for more than a day, the windshield will immediately have a thick layer of dust. This also indirectly increases the workload of the wipers.

Most people may understand that wipers are only used when it rains, and the main function of wipers is to clean up the water traces on the windshield. In fact, another very important function of the wiper is to remove the dust on the windshield.

Therefore, whether it is sunny or rainy, wipers are used almost every day. The higher the utilization rate, the corresponding service life will be shortened.

In addition, if there is a lot of dust on the windshield, we should not use the wiper directly, we should first use a rag to clean the dust on the glass, and then use the wiper to clean, otherwise too much dust will stick directly to the wiper, which will accelerate the shortening of the service life of the wiper.

Whether it is a new energy SUV or a fuel SUV, in terms of the appearance of the vehicle, we will find that there is a rear wiper on the rear trunk of the vehicle, and for the sedan, the rear trunk does not have a rear wiper, and it is not difficult to understand from the structure of the vehicle.

In addition, the rear tail of the current SUV adopts an integrated hatchback design, their rear windshield and tailgate are integrated, and it can be easily installed and fixed rear wipers, but it is different for cars, the sedan is in the structure, due to the structural problems of the rear trunk, resulting in the rear wiper can not be installed, and at the same time, it will also interfere with the door and the tailbox due to the sealing and the opening of the tailgate door, the rear windshield is fixed, and the wiper must be installed after it is easy to be misplaced. Secondly, in terms of the aesthetics of the vehicle, the sedan itself is out of tune due to the protrusion of the rear trunk and the presence of rear wipers.

In addition, the water mist generated by the rear wheels during the driving process of the vehicle will be adsorbed on the rear trunk door, and the SUV will be structurally speaking, because of the structure of the rear tail, the muddy water at the rear will be thrown off the rear glass and affect the line of sight, and the SUV needs to install rear wipers to clean the rear glass to prevent the rear glass from being too dirty and affecting the owner's line of sight. In addition, it is related to the flow direction of the air on the upper surface of the car, because the rear part of the SUV will produce a vacuum belt, which is not conducive to the flow of water droplets and affects the line of sight, so the rear wiper is required, and the vacuum belt behind the sedan is under the trunk.

Of course, the last point is also determined by the car manufacturer's own control of the production cost of the vehicle, after all, for the rear wiper, the road conditions are now better, and at the same time, with the heating function of the rear windshield glass, the rain will not have any residue, then the rear wiper for the car is not as significant as the SUV, so the car does not, and the SUV has.

The rear wiper functions similarly to the front wiper, both to clean up water droplets on the glass and make the driver's vision clear. Generally, SUVs will have but sedans will not, the reason is that because SUVs have a higher body, the airflow will accumulate dust through the rear window, so rear wipers are required.

The function of the rear wiper is the same as that of the front wiper, which is used to remove dust and rain from the glass. Generally, SUV models have rear wipers, but sedans do not, mainly because the body structure is different, the rear wipers of the sedan are not easy to fix, and the position of the tail box and the wipers conflict, so there is no rear wiper.

When it's raining, you'll need rear wipers if you want to see the traffic behind you through the rearview mirror. When the car is driving normally in the rain, it generally only pays attention to the traffic conditions in front and left and right, and the rear wiper at this time is dispensable.

When it rains, drivers need to use windshield wipers to maintain the clarity of the windshield, if there is a problem with the windshield wipers, resulting in the windshield brushing is not clean or can not brush off the rain, it is undoubtedly a huge safety hazard for drivers. The wiper can not work normally, it is nothing more than the aging of the wiper strip, the angle offset, the spring failure, etc., after finding that the wiper has a problem, the driver should immediately go to the repair shop to deal with it, to ensure that the windshield vision is clear.

A car wiper is a long black item on the front windshield of a car, which plays an important role in driving safety. On rainy days, dripping rain can block the view from the front windshield, and a car wiper is an accessory that brushes the rainwater onto the windshield to allow the driver to see the road ahead.

Car wiper drive mode.

The driving mode of automobile wiper can be divided into mechanical, vacuum, pneumatic, hydraulic, and electric. At present, electric wipers are commonly used in automobiles, which are composed of motors, crank degrees, transmission rods, wiper arms, and wiper blades. Its advantages are simple structure and convenient control.

The role of car wipers.

Car wipers are devices used to brush off raindrops and dust attached to the windshield of vehicles, which can improve the driver's vision and increase driving safety in rainy and snowy weather. Nowadays all cars are equipped with wipers, in fact, trains, trams, and light railways are equipped with wipers.

Car wiper switches**.

The wiper switch is located on the lever at the lower right of the steering wheel, and the wiper usually has some functions such as moving, stopping, intermittent, low speed, high speed, etc., which is to control the working frequency of the wiper. There is also knob lever adjustment, which adjusts the working frequency of the wiper by the position of the icon.

Saying goes. Sparrows are small and complete. The same goes for cars.

In our daily lives, we use cars a lot. They have evolved from a travel tool to an indispensable companion for us. With the improvement of people's living standards, people's requirements for cars are getting higher and higher.

So today, let's learn about the features of car wipers!

What is the function of car wiper — &mdash Profile.

Most wipers include real air wipers, electric wipers, and wipers with electronically controlled tease control units. The disadvantage of vacuum wipers is that the wiper blades move at an unstable speed. When the vacuum level of the engine drops, such as when a car climbs a hill, the wiper blades stop, which blurs the driver's vision.

True empty wipers were phased out in 1972 and replaced by electric wipers.

What is the function of car wiper — &mdash basic structure.

Electric wipers are driven by electric motors, most of which are composed of wiper arms, wiper brush assembly, rubber brushes, brush grips, brush grips, wiper arm spindles, wiper floor plates, motors, deceleration mechanisms, drive rod systems, drive rod hinges, wiper switches and wiper switch knobs, etc. Of course, wipers with rain wiper ECU are also equipped with an ECU. Electric wipers are driven by an electric motor.

The upper and lower wiper blades of the wiper are pressed against the outer surface layer of the windshield by the wiper arm. The motor drives the deceleration mechanism to rotate, and does reciprocating motion through the drive rod system, driving the wiper arm and wiper blade to swing to the right to scrape the windshield.

What is the function of the car wiper high content — &mdash principle of operation.

The motor on the electric wiper drives the output shaft through the worm gear on the armature shaft, and drives the output gear through the idler pulley and idler shaft, and then the output shaft operates the output arm connected to the wiper linkage. When the motor rotates, the drive output arm and connecting rod move back and forth. The resistance on the regulating switch is connected with the armature winding of the motor to adjust the speed of the motor, and the driver can turn the switch so that the current enters the input circuit of the motor.

The above is a brief introduction to the function of the car wiper by the car, and a brief introduction to the function of the car wiper. The car briefly introduced three aspects for friends, namely the introduction, basic structure and working principle of the car wiper. From the brief introduction above, we can see that the function of the wiper is to clean the car windows.

So how much do friends know?

Millions of car purchase subsidies.

Here's how:

1. Pull up the wiper and touch it with your fingers on the cleaned rubber wiper to check whether there is any damage and the elasticity of the rubber blades. If the blades are aged, hardened, and cracked, the wiper is unqualified and needs to be replaced in time.

2. Place the wiper switch at various speed positions to check whether the wiper maintains a certain speed at different speeds. Especially in intermittent operation, it is also necessary to pay attention to whether the wipers maintain a certain speed when moving.

3. When wiping, if there is uneven swing left and right, noise or abnormal beating of the wiper; The wiper strip does not fit perfectly to the windshield surface, and the wiper is not clean, and the appearance of water film, fine streaks and residual status conditions all indicate that the wiper is damaged or unqualified.

4. You can also distinguish the quality of the wiper by listening to the sound, when the wiper motor "buzzes" and can not rotate, it means that the mechanical transmission part of the wiper is rusted or stuck, then the wiper switch should be turned off immediately to prevent the motor from being burned, indicating that the wiper is unqualified.

If the wiper is unqualified, it will directly affect the driver's driving sight, rain and snow day is not very good, if the wiper is not forceful, it poses a great threat to driving safety.

After using it for a little longer, there will be various small problems with the car wiper, and replacing it is of course the best measure, but we also have to analyze the reasons and know what to do. Generally speaking, the wiper of a vehicle will have the following fault phenomena: Fault 1:

Fine streaks, fog and linear residues are formed on the glass.

Causes: Attachment of foreign bodies, sand, dust or damage to the triangular tip of the triangular edge.

Solution: Clean the sharp edge or replace the wiper blades.

Fault 2: The swing is not smooth, and the wipers are not beating normally.

Reason: The tip of the wiper blade is curved and wavy, and there are other attachments such as wax or oil film on the glass surface.

Solution: Wipe the glass part clean or replace the wiper blades.

Fault 3: The contact surface of the rubber and the glass surface cannot be completely fitted, resulting in wiping residue.

Cause: After a long period of use, the rubber hardens and loses its elasticity or breaks.

Solution: Replace the wiper blades Custer.

Fault 4: After wiping, the glass surface is in a state of water film.

Reason: Deformation of the wiper rod due to rust or external force.

Solution: Replace the wipers.

It sounds like the wiper has just been installed in the car, and the number of times it is not used is high, and when it is used on a rainy day, it is found that the wiper is not clean.

I have met many car owners in the repair shop to report this situation, which is roughly divided into two reasons:

Air impurities and oil stains are attached to the wiper adhesive strip on the glass, resulting in a thin line of scraping and brushing: Wash the glass thoroughly with oil film cleaning agent.

The rubber strip cracked and aged in the sun.

Countermeasures: If you can change the rubber strip alone, you can try it, the cost is not high, and if it doesn't work, replace the wiper.

However, you can pay attention to it when purchasing, a pair.

One or twenty yuan wipers are very cheap to buy, but they really break down after not using them a few times, which is equivalent to buying them for nothing.

Looking at the wipers of foreign brands on the Internet is too expensive, and finally I gave myself a Sylphy car to install Shan Duoli, checked it, several years of the company, there are manufacturers supporting the car factory, at least the original factory certification, the quality is relatively guaranteed, used for half a year, the quality is very good, cost-effective.

How to distinguish the quality of the wipers, a small way to get it.

Good material is not the same, how much hardness is high, and the toughness is also high There are good sales of the joint venture factory is almost the same It also depends on the workmanship of the plastic workmanship is good, the burrs are very few, and you can't see it, you take it and bend it to try (it was bent by others, hehe) The toughness is high, the resilience can be good, it is good, do you want to why your wiper can't be clean, it is deformed, indicating that the toughness is not good, and it is easy to be affected by the weather to deform.

-.-Lavida's wipers are too fragile! Is it that the fixing screws of the wipers are loose when driving, or if they are cracked somewhere. It's hard to say.

The original wiper is really not good.

It may be that the wiper arm is convex and concave, and the hanging is not clean. It may also be that the wiper strip is damaged, and the wiper strip can be replaced.

Change to a special wiper for special cars, or wiper strips.

Roadview auto supplies franchise store, ****, you can go and see, things are good.

When you buy a car, the car may have been produced and put away for a period of time, during this time, although the wiper has not been used, the usual sun and rain spray strip may have been aged, (the wiper strip itself is a fragile product, and it is also very afraid of direct ultraviolet rays). Created the kind of situation you just said.

In order to ensure the safety of driving in rainy days, it is recommended that you can replace a pair of new wipers, and you can check what are the well-known wiper brands before buying them, and choose a big brand.

Among the domestic brands, Sandoli is doing very well, ** is also more reasonable, you can buy it online or in physical dealerships, you can buy a pair to try.

The wipers equipped with the original car are garbage, so forget it.
