Lubrication for shrus There is a good activity of the equilized corner speeds for a good activity, lowers the rubber level, increases the efficiency of the system and does not give rust for some of the hinge items. Many auto owners are wondering - what lubricant to use for the Slus? We picked up for you material and functions them for comparison, which is in the assortment of lubricants. Also in the text we give info to use them in practice, and what people say on the basis of the personal experience of using the six most common lubricants with many drivers.


We will consider these aspects:

  • varieties Sls and the right quality for lubricants
  • types of used lubricants for hinges of the corner speeds
  • the type of lubricant used in heavy conditions
  • how to make a shred lubricant shift
  • models of lubricants for internal and external shrins
  • sAMI best grease

characteristic Sls, its properties and varieties

before moving to the description of the properties of lubricants, let's talk about the Sls. It is necessary in order to know what qualities should have lubricants for "grenade", as the words are referred to as the words, and with what makeup to use in those or other cases. The hinge exists in order to transmit torque from 1 axis to the second in the event that it is located at an angle, on the contrary. The value can reach up to seventy degrees.

Over the time of existence, the Sls were made by such of them:

Sharic. These are the most popular, specifically, their counterpart-lebro analogue.

Three (Tripod). They often use in the Russian automotive industry as inner solrs (those that are put on the side of the power drive).

Classic tripoda

Sucharicovye (Also called them - cam). They are often heated, therefore are put in trucks, where the speed of rotation angle is small.

Kulachkovo-disk. These are also put on trucks and buildings.

Paired cardan shafts. As a rule, used on construction techniques and trucks.

With considerable corners in the middle of the axes, the effect of the joints of the hinges will fall. In other words, the value that transmits the torque of the hinge activity is less. Therefore, avoid heavy loads with deployed wheels.

A special feature of each hinge of the corner of the angle has large loads of shocks. They appear at the beginning of the car, rises, riding on Ughabam and so on. Special lubricants Solmin All bad consequences are neutralized.

There are current hinges of the same corner speeds a lot (if you observe the tightness of the anther), and even as much as the car will ride. Lubrication must be changed when changing the anther or a total Sls. Although the shrines should be shifted to the shift shift after 100,000 km drive or one time at five years old (which will be required before).

Characteristics of lubricants for hinges of the same corner speeds

Since there are complex working conditions for hinges, lubrication Sls in order to protect the system from negative and provide:

  1. Increased stuffing coefficient of parts inside the hinge;
  2. Minimize the wear of some parts of the shruss.
  3. Reduce the mechanical load on composite nodes.
  4. Protects the surface of metal parts from corrosion.
  5. Neutral reaction with chinar rubber seals (anthers, plugs) in order to not spoil them.
  6. Pushes water.
  7. Durable use.

Based on all the above characteristics, the lubricant for the Sls should have such properties:

  1. Wide temperature Rangewhich will use the substance of extreme temperatures (current lubricants are able to function in degrees to minus forty and plus hundred forty and higher, this level will depend on the type of lubricant).
  2. The high degree of adhesion (it must be able to close with the mechanism, otherwise be a sticky).
  3. Mechanical and physico-chemical. The stability of the composition, which will ensure uninterrupted working processes of lubricant under all operating conditions of the car.
  4. High anti-promotional properties that will provide the desired level of sliding surfaces that smeared.

Thus, the properties of the self-sizing Sls must withstand the required requirements. Today, the industry produces many varieties with such a composition.

Types of lubricants for Sls

Lubricants are produced on the basis of different compositions of their mimic elements. We give and write the properties of the types used now.

LM47 Lubricant for Sls with Molybdenum Disulfide

Lithium lubricants shrus

These are the most old lubricants, they were used immediately after the invention of the hinge. In their composition lithium soap and various thickeners. Color them changes from light yellow to light brown, it all depends on the base oil of lubricants, which was used. They are suitable for use in conventional and maximum degrees. But when cold, viscosity is lost, therefore protect the mechanism is not as necessary. Maybe even hinges will tap with a strong frost.

The usual lithol-24 is also made of lithium lubricants, but it is impossible to pour it into the screen.

Lubrication Sls with Molybdenum

How technologies developed, the use of lithium lubricants has become less people. Therefore, the chemistry industry has developed advanced lubricants based on soap from lithium, but with the addition of disulfide molybdenum. If we talk about the properties of lubrication, then they are similar to the analogues of lithium. But the peculiarity of lubricants with molybdenum is that it has a large anti-corrosion property. This was achieved using a metal salt, replaced a little acid. These substances do not represent hazards for rubber and plastics, of which some details are made of the Sls, specifically, the boot.

Usually, when purchasing a new anther with him in a set there is a bag of lubricant. As a rule, it can be a fake. Therefore, before it is used, you need to check its composition, pouring a bit on the paper leaf. If she is not nasty or caused doubts - buy another lubricant.

Large flaws of lubricants on molybdenum is that they are afraid of moisture. If there is a little cloth under the boot, the lubrication can turn into abrasive with the consequences (parts are damaged inside the Sls). Therefore, if you use lubricant on molybdenum, constantly check the type of the anther on the frame of the Sls, it is its sealing.

There are such bad sellers who say that self-stalling for a molybdenum hinge will restore the broken node this is a bike. If a crunch appeared in the Sls, you need to spend repair work Either replace at the station that.

Famous species of goods from this series in Russia are lubrication SCLS-4, LM47 and others. About their pluses and minuses, let's talk below, as comparable to them.

SRB-4 Barium Lubrication

Barium lubricants

This type of lubricant today is the most modern and technological. Lubricants with excellent work properties, chemical stamina, are not afraid of water and do not communicate with polymers. They can be used as lubricating for the Solmin inside and outside (tripod).

Minos of lubricants at the barray is a decrease in functions at cold. Therefore, you need to replace each spring. Since the complex and technological production value of these lubricants is higher than those like that on lithium or molybdenum. The most famous Russian lubricant of this variety is SRB -4.

Sls - this system working in difficult conditions. Therefore, its lubrication must be excellent quality. Specifically, the screen is not to smear:

  • lubrication on graphat
  • technical. Vaseline
  • "Lubricant 158"
  • different compositions of hydrocarbon
  • compositions on the basis of sodium or calcium
  • compositions on the basis of iron and zinc

How to use lubricants at low temperatures

Many drivers from the North of Russia are wondering what lubricant to choose, whatever the case with strong cold (for example, minus 50 - minus 40). You need to decide by reading the information that the manufacturer gives. It is increasingly concerns not only Sls lubricants, and all oil substances, and liquids that poured into the car in the north.

Before going to the cold, we advise you to warm the engine very well, so that the oils and fluids, and the lubrication of the Sls, heated and were in working condition. Otherwise, the mechanisms will work for wear, and will be faster.

As the drivers say who live in the north, are good Russian lubricants "and Ravenol Mehrzweckfett Mit MOS-2. About what to choose, we will talk later.

Change of lubricant in shurts

The process of changing lubricants in the hinge of the same corner speeds, usually does not lead to difficulties, even if there is no experience in repairing a car. First you need to remove the silver from the car. In what sequence will act to depend on what car you have. Therefore, we do not give specific advice. We also do not forget that hinges exist external and internal. Their work is radically different from each other. Let's not go into detailed cases, but let's say that the basis of the Sls of external - balls, and the basis of the internal - rollers or bearing needles. Sls, which is inside, with large axial movements. Various lubricants are used for lubricating internal and outer hinge. Example of shifts We will show on the Sls three, as it is the most popular.

Before changing lubricants Sls know how much you need it. This material will be in the manual of your car. Although often this information is neglected, and drivers pour a lot of three into the glass. When the Sls will get, then the shift process passes by this principle:


How many lubricants for a shruss in "glass"

  1. We disassemble the housing. Often the frame is fastened with 2 rings of the stopper (rolled). And of course, to dismantle it, you need to remove these rings with a screwdriver with a flat sting.
  2. Remove the boot and seal rings. The fulfillment of this task should be checked for the antiquity of the antiquity. If necessary, buy new for installation.
  3. After you need to take all the mechanisms that inside, hinge and dismantle them. The tripod itself is held on the semi-axis ring of the stopper, it is gently removed. You will need a screwdriver.
  4. It is a pretty to wash off in gasoline or solvents details that were inside (tripodik, rollers, a semi-axle) in order to remove an old lubricant. The cup inside also needs to be cleaned of it.
  5. We lay down a little lubricant (about ninety grams, although this figure will range from the model of the Solmin) into the cup. What lubricant to choose for a tripode we will learn later.
  6. Mix the tripod on the axis in the cup, on its functional place.
  7. We repeat the lubricant from above, which remains, on the tripod delivered (as a rule, in tripods there are about 120-150 grams of lubricants). Put the lubricant exactly, turn the axis of the tripod in the frame.
  8. Then proceed to the assembly, which is conducted in the reverse order of sequence. Before tightening rings or homutics, lubricate the grooves of Lithol-24, or a durga lubricant.

Change lubrication on a shruss that outside, VAZ 2108-2115

Replacing lubricant on an internal shrus

As we see, the process of changing is easy, it can make it every driver who owns the simple abilities of the locksmith. The main task is what type of lubricant Sls is better and why? Now let's try to answer these questions.

Application of lubricants for shruses

Since the designs of the hinges that inside and outside, the same corner velocities are different, then lubricants should be different for them. Specifically, for the screen, what inside, we use such lubricant models:

  • Mobil SHC Polyrex 005
  • Slipkote Polyurea CV JOINT GREASE
  • Castrol OptiTemp BT 1 LF
  • BP ENERGREESE LS-EP2

Best lubricant

We found on the Internet the opinions of specific drivers about popular lubricants for the Sls, then they were analyzed. I hope this material will benefit you, and will answer a question - what kind of lubricant is best for Sls? Opinions are shown in the table as they follow their popularity, from strong to small. So we chose the five most popular lubricants Sls:

Patriotic lubricant Shrus-4

Lubrication, which is produced by several domestic enterprises. It was made for use in the 1st Soviet VAZ-2121 Niva. After it began to be used for the front drive VAZ. In addition to use in bearings with balls Sls, that outside, lubricant can be lubricated by carburats, telescope racks, clutch bearing. SHRUS-4 - mineral lubricant based on aquickered lithium. Its temperature properties: degrees of work - from -40 ° C to + 120 ° C, dropping degrees - + 190 ° C. The cost of the tube in 100 gr. It will cost one-day $, and a tube of 250 grams - two or three $. Catalog number sign - Oil Right 6067.

LIQUI MOLY LM 47 LANGZEITIFETT + MOS2.

Lik Moli LM 47 Langzeitfett. + MOS.2. Lubrication has a kind of dense Plastic substance dark gray, almost black color, produced in Germany. As part of lubricants, a set of lithium (like a thickener), as a base oil on a mineral, a set of additives (even against wear), particles for lubricant solid, which reduce rubbing and wear. It is used in the screen that is outside. In addition, it can be used when servicing electric tools, typography and C / x, stroke machines for lubricating the threaded part of the guides, shafts of the slot, high-loading hinges and bearings. Degrees of work - from minus 30 to plus 125. The cost of one for 100 gr. - Four to five dollars (license plate Catalog Liquimoly LM47 1987), and 400 gr. - (Liquimoly LM47 7574) will cost nine ten dollars.

Ravenol MEHRZWECKFETT MIT MOS-2Schedule marks Ravenol are made in Germany. Disulfide Molybdenum, which is part of it, prolongs the time of operation of the Sls and reduces their wear. Lubrication resistant to salted water. Degrees of use from minus 30 to plus 120. The cost of one in 400 gr. About five to six dollars. In the catalog you will find this product with a room with a number 4014835200340.


Sls MS X5

Sls MS X5. Also domestic brand. The class of the composition of NLJs is two thirds. Classic 2 is a transparent penetration of 265-295, lubrication is not hard. It must be said that species 2 and 3 are usually for lubricating bearing (specifically, the type 2 is more common to the medium of lubricants for l / a). Grease color - black. The density is soap on lithium. What is used x5 makes less routing in bearings. Even with a damaged boot, the lubricant will not follow. Degree mode from minus 40 to plus 120. Degrees drop drop - plus 195. It costs one in 200 grams. Three four dollars. You can find it in the book under the sign VMpauto 1804.

Hado for a scrub. Ukrainian production. Excellent and inexpensive. Enjoys for the screen that is outside. There is no disulfide molybdenum in it. Color-amber-amber. A feature is something that there is a revitalizant - a substance that is able to restore the detail geometry that function with the load. You can use not only Sls, but also in other nodes and systems. Class of nice spleens in NLGI: 2. Degree mode from minus 30 to plus 140 (briefly up to plus 150). Handling degrees - plus 280. It costs one at 125 grams about six to seven dollars, costs 400 gr - ten or twelve dollars. Code designation - XADO XA30204.

Lubrication Step Up. - withstands large degrees with SMT2 for the Slus. Made in America. Used both outside and inside. Withstands high temperatures, it has a degree mode from minus 40 to plus 250. It has a CT2 Metal Conder, a lithium complex and molybdenum disulfide. It costs in 453 gr. - Eleven to thirteen dollars. You will delete it under the number of STEP UP SP1623.

Outcome

Conduct the process of changing the hinge lubrication of the same corner speeds according to the recommendations that give manufacturers of your car. Remember, cheaper to purchase lubricant for the screen, than to repair or replace the hinge itself due to breakdowns. Therefore, do not neglect this. If we talk about the choice of the model of a specific, then it recommends not to go for the seeming benefit and not take small at the cost of lubricants. For this money you can buy a good product. I hope that this material was useful to you, and now your decision is to buy - will be correct.

Ravon Uzbek production cars will be operated in law enforcement agencies in Russia.

This information was provided as part of the Dealer Conference in Moscow, which was held in honor of the start of sales of brand cars in the Russian market.

The participants of the event was shown updated sedan R4 used in Moscow DPS. From the standard version, the car is distinguished by unusual liveries, as well as the presence of additional functions intended for law enforcement officers.

Cars equipped with front-wheel drive have many advantages - often they are lighter, they are cheaper and easier to produce. Also the front-wheel drive cars have more high passability On slippery areas. But there are certain disadvantages. So, the Sls in the drive not only ensures uniform straightness of the movement, but also causes the rapid wear of parts and transmission nodes.

To increase the reliability of drive and transmission mechanisms, a special lubricant has been developed, with the help of which the situation has improved. Then many different products began to appear on the lubricating materials market, which created confusion, and motorists had to tolerate some inconvenience. To avoid mistakes, you should know what lubrication Sls is most effective.

What tasks solve lubricants Sls

Even a novice motorist knows that lubricant, which is used in most nodes, decides not only the task of reducing friction and wear of parts. It is also designed to reduce the load that mechanisms are experiencing. Lubricants make rotation more easier and free, and the car can move forward without any obstacles. Lubrication Sls In addition to lowering friction also reduces fuel consumption and energy loss in transmission.

The second equally important property of lubricants is the protection of metal components from corrosion impact. It is not a secret for anyone that the bulk of all breakdowns of parts in the mechanisms is the consequences of considerable corrosion. Lubrication must protect the details of the shruses from such processes and thereby ensure the durability of the node. A good product will save the owner of the car from unnecessary costs.

Views of lubricating materials

Front-wheel drive cars, as well as their all-wheel drive bonuses coexist for many decades. During this time, many varieties for the Sls appeared. In general, each composition completely effectively performs its functions. But some of the proposed lubricants have aggressive properties in relation to the rubber or plastic. Many compounds also do not have proper properties to combat corrosion, and this is almost the most important characteristic of the lubricant Sls.

Lithium-based lubricating

This is a mixture of yellowish shade and high viscosity. When decreasing temperatures, viscosity increases. In the frost, lithium lubrication can be labeled with great difficulty. Lithium compositions are perfectly coping with a decrease in friction. In addition, the lubricant in tens of times reduces the loads that affect the drive mechanism and its components.

It is also noted the conservation properties of these materials - it is the products on a lithium-based basis to protect the metal from the effects of moisture and dust, as well as other pollutants. But this can be said far from every composition, it happens that any product does not have the necessary characteristics to combat the destruction of the shruses due to the impact of corrosion. Experts recommend motorists regularly check the status of the drive system and all nodes. The frequency of such checks is 50-60 thousand kilometers.

One of the exceptions that are quite a bit, is the lithium domestic lubricant "Litol-24". Russian automakers recommend not to replace it earlier than in 100,000 km. Lithium-based formulations can be safely used with any polymeric coatings, which are used in the manufacture of anthers in the Sls.

Brands

Today, among producers, domestic lubricants are leading. Many foreign firms gradually refuse these compositions due to the development of newer and modern technologies. Newest Development allow you to provide maximum protection for each part in the transmission.

Despite this, there is always a lithium lubricant Sls from manufacturers such as Hado, Very Lube, Renolit.

Products based on Disulfide Molybdenum

Although lithium lubricant Sls and has high efficiency, the search for new technologies and solutions continues. The composition must be ideal for all cars. As a result, the compositions of the new generation were created. Their feature is Molybdenum Disulfide. This made it possible to increase resistance to corrosion. As the resource tests have shown, even after 100,000 km in the shurts there was no serious wear. But even this unique composition is not eternal - the replacement will be required through a hundred kilometers.

Fear of liquid

It is noted that such compositions have a serious minus. Molybdenum products are very afraid of moisture, which can get from the road inside the mechanism. As a result, the composition completely loses its properties.

Brands

In order to choose the best, you should not pay special attention Price. Often lubricant Sls with a lower price has greater efficiency. Excellent example - domestic products "Slsus-4". As part of a lot of molybdenum, which best affects the durability of transmission nodes. From foreign brands you can recommend BP, Liqui Moly, Mobil, Esso.

Grease

All that is mentioned above is relevant only for external hinges of angular velocities. No lithium products nor molybdenum are suitable for internal nodes. The fact is that work inner scrub passes in more high temperatures. Efficiency lithium lubricants It is lost already at 120 °, and the standard temperature for the internal nodes is 160 °.

As lubricating products, it is recommended to use polyurea-based compositions. Among the characteristics highlighted high temperature resistance, resistance before exposure to liquids, overall efficiency. The mixture on the basis of the polyurea is suitable as a lubricant for a triphide shrus. If the inner node is based on the balls, then it is quite possible to do with the product "Slsus-4".

Features of internal tripoid shrusov

As for trypoid hinges, they work at the expense of needle bearings. If there are any solid particles in the lubricant, it will lead to an imminent death of the mechanism. Sellers in stores are trying to sell car enthusiasts.

The lubricant for a triphide scruck can be both domestic and imported. There are suitable products on the polyurea in the Hado assortment. Also, many car owners recommend the Castrol LMX product, which is ideal for working in needle bearings.

What lubrication can not be used

Often, drivers become victims of marketing - they are offered the best and reliable product, which in reality does not have the desired properties. So, in the case of hinges of angular velocities, it is not recommended to apply graphite lubricants. Also do not fit the products on a hydrocarbon basis. In addition, mixtures based on calcium and sodium, as well as iron or zinc, will be destroyed by the mechanism.

How many lubricants in the shrus

So, the external shruses are filled with lubricant so that the composition be a little over the part borders. Internal can be discolored slightly - poured so that about 3-5 mm remains to the edge.

How to choose a good lubricant?

Today is very optimal option - Means with Molybdenum Disulfide. Here and high corrosion protection, and decrease friction in nodes. As a universal lubricant, you can apply "SCLM-4" or "Litol-24". And the best lubricant for shruses is original Materialthat recommends the car manufacturer. So when choosing, be careful.

  • ease and simplicity in production;
  • Shrusi provide uniform movement;
  • excellent permeability on slippery surface.

But with this, the front-wheel drive cars have a significant drawback - the transmission mechanism is quickly wearing. To extend the service life should be used by a special lubricant for nodes. Modern manufacturers offer plenty of lubricant materials. To not be confused and not confused in the proposed assortment, you need to know what a lubricant for a shrus is better.

Attention! In addition, for high-quality replacement of lubricant, you need to know how much lubrication is needed for a shrus.

Requirements for lubricants for shruses

Lubricant, which is used in car mechanisms, reduces the friction of parts, respectively, it leads to the prevention of their wear. Lubrication reduces the load on the mechanisms, makes them rotating more free, and this allows the car to be easily riding. Another positive moment of lubrication is to reduce the consumption of fuel and losses in the transmission vehicle.

Modern lubricants are excellent rust prevention. With the appearance of rust, empty cavities arise in the shurts, due to which the transmission efficiency is reduced, and the knock is clearly heard. Thanks to the lubricant, corrosion does not occur, the shoes serve for a long time, and the motorist does not spend money on the purchase of new details.

An important property of the lubricant used is gentle influence on organic and synthetic polymers. Since the shruses are protected from pollution and dust with rubber or plastic dust, the lubricating composition should not affect them.

A variety of lubricating compositions

Manufacturers are constantly working on improving lubricant for shruses. For a long period from the moment the front and rear drive Many different compositions have been developed. Each of them coped perfectly with the main function - a decrease in loads and friction force in the details of the transmission. But some of them negatively affects polymer compounds and does not have an anti-corrosion action. What lubricant to use for a shruss?

Attention! To pick up the optimal lubricant, you need to know what kind of types there are also the features of each of them.

Modern manufacturers make the following types of lubricants for outdoor and internal shrus:

  • lithium;
  • based on disulfide molybdenum;
  • barium;
  • mineral.

Lithium composition

The most common and demanded compositions are lithium. They are used for automotive mechanisms that are susceptible to high loads, for example, for undercarriage. This material has a yellowish color and a viscous consistency made from lithium solution, which is pre-foamed in an organic acid. The lower the temperature, the thickness becomes the composition and it is harder to smear on the details. The material of this type perfectly prevents the wear of parts, as it repeatedly reduces the load on the drive. In addition, they have a moisture proof on the details, eliminate the dust and dirt that fell inside.

Despite all the advantages of lithium compositions, not all of them can fight against pitting of shruses. Auto mechanics are recommended to systematically check the drive system every 50 thousand km of mileage. The exception is the product based on lithol-24. Experts recommend to change it after 100 thousand km of mileage.

The compositions that are based on lithium are not affected by most of the polymers used for the manufacture of shrusers.But several car manufacturers Made anthers from high-strength plastic organic character. Litol and its analogs dissolve organic materials. When using such products, you should carefully read the instructions for them, there will be indicated what means to apply to protect them.

To date, world leaders in the production of lithium compositions are russian manufacturers. Abroad preference is given to more modern technologies. Nevertheless, there are still on sale foreign lubricants for HADO, Renolit shruses and other well-known brands.

Molybdenine Disulfide Based Compositions

The lubricant material of the new generation is the compositions made on the basis of the Molybdenum disulfide.In contrast to other species, these compositions provide reliable protection Car mechanisms from corrosion. Tests show that after 100 thousand km of mileage, shruses do not have serious damage. But still specialists recommend replacing lubricant after a hundred thousand kilometers of a run or every five years.

Molybdenum disulfide-based compositions ensure reliable protection of friction mechanisms, and the low organic acid content does not exhibit aggressiveness to the surface of polymers. Despite all the advantages of the composition of this species have one significant minus - it loses its properties when moisture gets into the Sls, and the consequence of this is the destruction of the mechanism.

Therefore, when using products based on disulfide, Molybdenum must be made monthly preventive inspection Anthers. In addition, there must be extraordinary inspections after driving bad roads Or after strikes on the bottom of the car.

Manufacturers of such formulations recommend using them in any cars. When choosing a lubricant based on disulfide Molybdenum should not be guided by the price. Often products with low price is better than materials with high cost. An excellent option is the domestic lubricant Shrus-4, and from foreign analogues, experts recommend using Liqui Moly, Esso, BP.

Barium-based lubricants

Barium compositions for shruses became an alternative to lithium and lubricant materials based on the Molybdenum disulfide. The main plus of barium products is high moisture resistance. It can also be noted such advantages of barium-based lubricant, such as anti-corrosion properties and neutral chemical composition, which is not aggressive in relation to anthers. Minus barium lubricants is low resistance to frost temperatures.

Attention! The compositions containing the bar have not yet become widespread, as they have enough high cost. From domestic products, it is possible to note SRB-4, its foreign analogues are much more expensive.

Mineral formulations

Mineral compositions for shruses have reliable protection against corrosion and moisture. They show excellent indicators regardless of temperature. The lubricant is made on the basis of synthetic substances, lithium thickener, sticky agents and rust inhibitors. The leader among mineral compositions is the lubricant for Chevron shrus.

How to replace lubricant

To replace lubrication in shurts, it is necessary to dismantle running part cars. To do this, remove the supports and ties, then remove the shock absorbing racks and remove the item.

For pressing lubrication into the Sls, it is necessary to divide them into two parts - internal and external. Immediately lubricate the inner part, for this it is separated from the drive mechanism. To prevent damage to the details you need to apply on the body and support shallow notches,which then need to put in line with.

Then you need a dense cloth or paper napkins to wipe the car to remove the old lubricant and apply a new lubricant material. After that, you can move to the lubricant of the external shrus. It also needs to be cleared of pollution.

Many motorists have a question than to rinse the silver from the old lubricant? Experts recommend using special means, and not to apply soap or auto-pump for this. Washing parts need to wipe with a napkin and fill them with lubricant. After that, the outdoor boot of a shrussa with lubrication is set back to the car.

Another logical question - how much lubricant lay in the Slus? The weight of the lubricant for needle bearings of the shruss is approximately 115 g, and for the external node - 135. Visually, it is possible to determine this - on the outer part of the part, the lubricant should be slightly out of its limits, and in the inner - not reach the edge of about 0.5 cm.

How to fill the lubricant into the Sls can be viewed on the video:

What is the hinge of equal angular velocities (Sls)? From a mechanical point of view, this is a rolling bearing with a small number of balls. As a rule, their three in small cars, and six in larger transmissions.

A fundamental difference from ordinary ball bearing - working conditions. Open housing, freedom of movement is obliged relative to each other, other ratio of the diameters of balls and for a row.

Accordingly, the maintenance of these nodes differs from classic bearings. Traditionally, lubricant Sls 4, or similar compositions.

This consumption is designed specifically for the automotive industry, the article corresponds to TU 38 201312-81. Consystem grease This type is laid in the semi-axis on the conveyor, and is offered in a free sale for regulatory work.

Characteristics and application of lubricant Sls on the example of different mechanisms

Why for hinges of equal angular velocities does not suit the usual liquid oil, as in gearboxes or distribution? The design of the hinge does not allow you to fill this node with lubricant even until the middle.

Carter is missing, the outer body is a rubber or composite boof. Tightness is provided by clamps, and the oil is simply leaving under the influence of centrifugal force.


Despite the fact that in the gearbox (or in the rear axle gear) there is a liquid oil, its crankcase and the shell cavity are not communicated to each other. Therefore, mixing lubricants is excluded.

Types of hinges:

  • ball - the most common and universal design;
  • Sls Tripoid applied in domestic (and some foreign) cars with innerwhere the break of the hinge is minimal;
  • sukharikovy are applied on trucks: characterized by a high torque and low angular rotation speed;
  • kulachkovo-disk hinges "digest" monstrous torque, and work at low speeds;
  • shrusa Replacement - Paired cardan Val. (The lubricant is only inside the cross).

When working the corners of the shafts can reach 70 °. Technical characteristics of plastic lubrication must provide normal performance of the hinge.

  • reducing the friction coefficient on contacting surfaces;
  • improving the wear of the hinge;
  • due to antifriction additives, mechanical losses inside the node are minimized;
  • non-failed properties (perhaps the most important characteristic): Zadira index is at least 550 N;
  • protection of steel cuttings from internal corrosion;
  • zero hygroscopicity: when the temperature drops, condensate can be formed, which does not dissolve in lubrication;
  • water repellent properties (from moisture penetration through damaged anthers);
  • chemical neutrality in relation to rubber and plastic details;
  • durability of use (replacement of lubrication is associated with a large amount of work);
  • neutralization of abrasive properties of dust and sand falling inside the hinge (for obvious reasons, oil filter It is impossible to use);
  • wide temperature range: from -40 ° C (ambient temperature) to + 150 ° C (normal heat heating temperature);
  • high temperature dropping;
  • strong adhesion to hold lubricant on the surface at centrifugal splashing power;
  • preserving the laid characteristics with short-term overheating, and returning viscosity rates after cooling to operating temperature (loading load at least 4900n, and the critical load is at least 1090n);

For an internal shrus specifications There may be less demanding, but usually the same composition is laid in both "grenades". Just a more frequent oil update is required for an outdoor shrus.

Varieties of plastic lubricants for hinges

Lubrication Sls 4 has long become a none name, although the composition of different manufacturers is different.

Slus 4m

The most popular is the lubricant Sls with disulfide Molybdenum (Actually, GOST or TU Sls 4m). This additive provides excellent anti-corrosion properties due to the presence of metal salts that neutralize the acid.

This property is especially useful in the case of the loss of the tightness of the anther. An explicit gap is easily noticed, but the weakening of the clamp is practically not diagnosed. However, the lubricant itself when moisture gets starts to lose properties.

Molybdenum disulfide does not affect rubber or plastic, does not react with non-ferrous metals.

The notorious lubricant "Supethek" for the shruses is simply restores the smooth surface, the new metal does not grow. Lubrication S. molybdenum additives Well tolerate low temperatures. Even at -50 ° C, the hinge confidently turns and does not swallow due to thickened oil.

Barium additives

Cams are durable and technological. Imported (expensive) options are quite a lot, and for economical drivers there is a domestic version: lubricant Sls for the tripode SRB-4

This advanced composition in principle is not afraid of moisture. Even if the fluid falls through the damaged boot, the properties of the lubricant will not deteriorate, and the hinge metal will not be corrosive. Chemical neutrality is also on high level: Anthers do not dub and do not swell.

The only problem of barium additives - Reduced quality at low temperatures. Therefore, in the conditions of the Far North, use is limited. For the middle strip, with short-term frosts, it is recommended to warm up a hinge at low speeds. For example, maneuvering in the parking area.

Lithium lubricants

The oldest option arising with the screen. For thickening basic oil Lithium soap is used. They work well with medium and high temperatures, have strong adhesion.

Quickly return characteristics after short-term overheating. However, at minus temperatures, viscosity increases sharply to the state of paraffin. Accordingly, the working layer is breaking, and the hinge begins to wear out.

Is it possible to lubricate the silver with a lithol?

Trying to understand what a lubricant is better for shruses in the middle lane, drivers look at Litol-24. Despite lithium additives, this composition for hinges of equal angular velocities is not suitable.

The only way of application (taking into account the price availability), "fill" the node after replacing the torn anther, and follow the place of repair. Then rinse the hinge, and fill it with correct lubricant.

To determine which lubricant is better to use for the shruse, I recommend to watch this video

The principle of "porridge oil will not spoil", in this case does not work. Information on how much lubrication is in the Sls, in technical documentation No car. Principle Next:

  • the hinge cavity is filled plastic lubricant completely, without the formation of air bubbles;
  • then the part of the node is made, which is closed with a boot;
  • it puts on the boot, and slightly crimped with hands: the extra lubricant is squeezed along the semi-axis;
  • after removing it, you can crimp the clamps.


"Excess" lubricant when heating a hinge can break the boot.

How to rinse Sls from Old Lubrication - Video

Some motorists do not know the names of the nodes of the machines. Therefore, in the process of repairing or during communication with specialists, difficulties may arise. Sls - this is a hinge of angular velocities.

There are two types:

  • external - for rotation directly hubs;
  • internal - to transfer torque from the engine to wheels.

Composite parts of the node

The knot is known to humanity for a long time and indispensable in cars. The design is simplicity and, with proper maintenance, will serve correctly and for a long time.

Composite parts of a shrus:

  • housing - in the form of a bowl;
  • owl with oil - is inside;
  • separator - ring opening;
  • six balls - as in the bearing.

For trouble-free operation of the device requires its timely service. Since the node has fading details, it is required to be lubricated in order to:

  • reduction of friction;
  • reduction of wear;
  • lowering loads on rubing parts;
  • protection of metal from corrosion.

The oil is short-lived and periodically should be changed. But questions appear:

  1. What mixture to choose?
  2. How to do it?
  3. How much mixture to fill in the screen?

About lubricant

Each node of the car has its own features of operation and care. Before purchasing something, you should read the instructions and find out the recommended lubricant.

Lubrication selection

If the manufacturer does not indicate which lubricant to use for shruses, you can use a universal agent. You should choose carefully because the device is operated under serious loads.

To minimize! All lubricants are made of oil. Fake fakes.

In the auto shops you can purchase a special mixture, which is different:

  • high viscosity;
  • strength.

This is required to hold the substance on the surface of moving parts even at high temperatures. Oil features:

  • the invariance of characteristics under changeable conditions;
  • anti-corrosion properties;
  • the ability to save your initial characteristics for a long time.

When changing lubricant

Replacing a viscous substance in shruches is made in the following cases:

  • when mileageing a node over 100 thousand km.;
  • when replacing the anther knot;
  • when replacing the shrus itself.

The number of required lubricant when replacing is indicated:

  • in the car manual - not always;
  • on the package - always.

Disaster node and its promissory

Disbanding an internal shrus (tripod)

Attention! Memo seats of parts of the node. Take marks. Everything should be back into place, especially balls.

Replacement algorithm when replacing:

  1. Unscrew the nave nut.
  2. Throw balls.
  3. Loosen the coupling of the inner shrus.
  4. Become racks.
  5. Get the item.
  6. Remove the lock ring.

Lubricant

Attention! Prepare the materials for cleaning from the old lubricant. You can not use the solvent.

Details removed must be cleaned up to shine. To remove the old lubricant, it is advisable to use paper, and for final cleaning and polishing - towel.

The algorithm for lubricating parts during its replacement:

  1. Score the bottom of the grenades with a mixture.
  2. Collect a hinge.
  3. Install a lock ring.
  4. Lid axis.
  5. Check the coincidence of the rods of the tripode.
  6. Score the whole knot.
  7. To exit lubrication to outward its small amount in the boot.

Disaster of an external scrub

  1. Press the separator with balls.
  2. When tight a melting can be knocked through a plastic or wooden part.
  3. Taking the balls to remember their places. For this purpose, cardboard with holes are useful, you need to insert them there to not confuse the place when you return.

Lubricant

Lubricant Replacement Algorithm:

  1. Remove all parts from the old substance.
  2. Rinse and dry.
  3. Inspect the details for damage.
  4. Lay lubricant into a glass.
  5. Lubricate the clip and insert balls exactly to the place.
  6. Insert the clip into the glass, fix the separator.
  7. Remove excess lubricant.

Remember! The external node will require 120-150 grams of oil, internal - 100-130 grams.

For clarity, you can use the video material:

Replacing without parsing

Replace lubricant in a shooter and without removing it component parts. For this you need:

  1. Remove the shrus itself from the car.
  2. Insert the tip of the Tyuba and press the oil inside the node.
  3. Tightly press the Tube and wait until the color of the substance changes to fresh.
  4. Wash the detail, removing excess substances.
  5. Put the item in place.

Attention! This method has one drawback - a thin layer of the old substance remains on the walls of the parts inside.

No need to rush to use a blurred knot when driving. Worth it scroll the node in place while the car is suspended on jacks. It is necessary for the uniform distribution of lubrication in detail.

Attention! On the car with automatic transmission with hung wheels, the pressure in the system will quickly subsides.

The process of replacement is not so complicated and in the presence of a minimum set of tools and skills to simply do it yourself. It will save money and make it better to feel the car. And remember quality replacement No lubricants are not done without removal. If it is not possible to remove the node, it is better to go to the car service to those skilled in the art.
