Sometimes in the rain, with a very difficult road conditions, the timely detection of obstacles can prevent an accident and even save lives. Not the least role in this case, act out the windshield wipers of the vehicle windshield. The effectiveness of the wipers (ie windshield wipers) largely depends on the correct choice in the process of purchasing and installation. About this further in the article.

Wipers for automobiles, which are made of, how long are

wiper brushes are consumable material which ensures proper operation of the vehicle, as well as filters or oil in the transmission and engine. And, as any supplies, they are a limited resource.

Some sources advise to change the wipers twice a year, while others - once in two years. However, most car owners prefer replacement wiper only at a significant unproductive their work.

The life of the wiper affected by many factors:

1. The use of active chemicals to car washes.
2. "Age," the part itself, its quality.
3. Effect of high and low temperatures.
4. Damaging effects of salts, which in winter treated roadbed.

As a result of such influences, tires brushes stiffens and its adjacency to the glass decreases.

The main component of the wiper - rubber element. Now do not make the wipers of pure rubber, because it freezes in the winter and in the summer heats up in the sun, resulting in dry or bursts. Working part of the "gum", as a rule, it is made of wear-resistant and hard rubber or a special silicone-graphite mixture. Because the operating part is bent when moving up and down position of inflection is made of a soft and flexible silicone. Mounting is made of heat-resistant durable rubber. wiper frame is usually made of metal or plastic.

Apparatus automotive wiper

The vehicle is usually equipped with a double wiper on the windshield and a single - on the rear window. Windshield wiper can be operated in three modes:

• Fast work.
• Slow work.
• Intermittent operation, when performed one oscillation every 3-5 seconds.

Windshield wiper comprises brushes arm system, the motor with reducer and control that provides automaticity brushes return to its original position while translating the switch lever in the position "off". Together with the janitor operates the windshield washer and which consists of a nozzle, lines, reservoir, and the liquid pump that is actuated by an electric motor. Included washer wiper arm turn, by means of its movement perpendicular to the plane of the steering column.

As for the rear window wiper, it consists of a brush, a lever, an electric motor with gear and control. Together with wiper operates and rear window washer, which consists of a nozzle pipe and a pump that is driven by the motor. rear wiper is turned together with the washer (there is a separate switch) and operates only at one speed.

Form wipers of a modern car

To date, there are three types of car wiper - hybrid, frame and frameless.

Frame wipers They are the most common in the domestic market. Structurally, a windshield wiper system consists of joints and rocker arm, on which the wiper blade is fixed. Even a decade ago, most of the carcases of such wiper made of metal, but in the mid-2000s, the metal began to replace the more practical and modern materials. This is due to the fact that in the course of work of janitors, which consist of a metal rocker and joints, rocker wear out quickly, which entails a high wear, play and, as a consequence, inefficient work of janitors. In addition, the metal parts of the wipers are prone to corrosion and freezing.

In this regard, most manufacturers began to make the axis of the sleeve and the plastic hinges. This makes it possible to avoid large backlash, frosting that quality affects the precision of the connection frame components. With this data frame wipers have excellent rigidity in the transverse direction and, as a consequence, the rubber blade is effective against the glass surface.

But there are downsides. If plastic is defective, then after a small time interval the influence of external weather factors leads to destruction of its structure. This causes the formation of voids and cracks, which in turn entail scratches during operation and considerable backlash in the joints.

frameless wiper There are plastic or rubber-plastic cast housing, where they are filled, as a rule, two metal plates, between which the rubber blade of the janitor is fixed. Such a wiper in the form is made as a spoiler. In the central part of such a janitor, there is a special bracket for fastening, and plastic plugs are installed at its ends. The advantage of this design is stability to icing, as well as the absence of a set of rubbing parts - sleeves, hinges, axes. In addition, frameless wipers actually work silently on glass during movement and do not have noticeable distortions, which makes it possible to significantly extend the life of such janitors.

But there are also flaws here too. The first and, probably, the most important disadvantage of the data of wipers is not universality. Due to the fact that the metal plates are made with a bend, they can only be installed on those glass whose curvature corresponds to the bend parameters of the janitor. In other words, for each specific glass model produced certain wipers. In addition, the fastener brackets are not unified among various manufacturers, so each specific car model can only be used for it designed for it.

There is a third class of janitors - hybrid. This design combines elements, both from frameless and framework wipers. These wipers have a frame with hinges and rockers, as well as a plastic casing that looks like a spoiler. But compared to classical frame janitors, hybrid possesses a small height frame. With this combination of two designs, the wiper wipers of this type have the positive properties of the two previous classes.

The only lack of hybrid wipers is a high cost, although a long service life blocks it. In addition, it is in hybrid windshield wipers that manufacturers apply only high-quality materials, especially this relates to the blades and their working edges. Most of the janitors of this type for a complete year do not lose its original geometry and elasticity.

Criteria for the choice of new janitors

There are several main points that should be considered when choosing new janitors:

1. The shape of the wiper brushes.
2. The size of the wiper brushes.
3. Type of fastening wiper brushes.
4. Information on the package.

the shape of the wiper brushes is important

The form of modern vehicles has become more streamlined in comparison with past generations of cars. Together with the amendments of the aerodynamic characteristics of the bodies of new cars, the form of the front (windshield) glass is changed. Therefore, most modern cars have not simple straight wipers, but the deposited as a result of a special glass configuration. It is very important to take into account this parameter when choosing janitors for your car, otherwise the brush will not be perfectly seamless to the curved surface of the windshield. Therefore, before buying, it is necessary to pay attention to the shape of the brushes - directly or with bend.

brushes size, how to find out the size of your own car brushes

Of course, to buy brushes to suit your car, you need to know their size. To do this, it is necessary using a roulette or a ruler to measure the length of each brush installed on your vehicle. If you purchase wipers too large, they can touch each other during work and, on the contrary, if you buy too small wipers, the glass cleaning area will decrease.

what fastener have wiper brushes

But even if you picked up the shape and size of the brushes, it does not mean that they are suitable for your car. It's all about fasteners that differ depending on the vehicle brand. There are several types of fasteners: "Hook" - "Hook", "Side Pin" - "side pin", "Push Button" - Mount "Button", "Pin Lock" - "Castle", "Side Mounting" - "Side mount ", Pinch Tab" - "side clamp", "Bayonet ARM" - "Baykow Castle", "Top Lock" - "Top Castle", "Claw" - "Cleash". Fastening the "hook" type is the most common not today.

universal fastening

Many wikist manufacturers are put in packing together with brushes special universal adapters for attaching brushes to leashes that allow you to secure brushes on a specific vehicle model.

information on the package (take note)

Pay attention to the packaging of wipers. It should have an informational inscription indicating the model of your car. If there is no such inscription, most likely, these wipers will not suit your car.

Installation of wiper brushes with their own hands (step by step)

1. We raise the metal leash, for which it is necessary to push it away from the surface of the glass to the extreme position. It is necessary to do it very carefully, you can not let the leash, otherwise it can damage the glass (because of the spring).
2. After removing the brush from the leash (for this you should pull it down), take the tissue napkin or a towel and put it on the glass, lowering the wiper without brush back.
   
3. Before applying new brushes, we process the gum of new brushes and windshield with a soap solution. Then wipe all the napkin or a dry cloth.
   
4. Installing new brushes by dismantling the protective elements (if any) and after opening the adapter latch.
   
5. Latch the adapter fastener and lower the brush on the glass.

How to check the work of the wiper brushes

1. We turn on the glass wipers on the middle speed (if there is a mode switching). Let them work for three to five minutes, making sure that new brushes can clean dust, dirt and other contamination. If the brushes are high-quality, then they even should not leave the pass, divorces, and also should not creak. Checking the brushes, turn off the wipers.
2. If there is an adjustment of the speed or speed mode, turn on this mode for three to five minutes. Make sure that the brushes cope with their work at high speed. Turn off the wipers.
   
3. We repeat steps 1 and 2 alternately, first turning the windscitters on the middle speed, and then to a large to test the operation of the brushes on the wet surface, for which it is necessary to water the windshield with water during the work of the janitors.

Council Pro: Change only the gum of the wiper brushes, and not completely brushes

The most important part of the wiper brush is its gum, since it is she who erases with glass all dirt and water. As soon as the rubber blade of the wiper is very worn, most of the car owners immediately runs to buy new wipers, but it is not necessary to change the wipers in such situations completely, it is enough to replace the gum itself, which is much cheaper and more practical.
