It would seem that it may be easier to choose a lubricant for hinges of equal angular velocities. If the packaging is written "Slusa Lubrication", and the like. - It can be safely taken and used. But, as in any other question, there are nuances that you need to know.

What is Sls?

Hinges of equal angular velocities (shoes) are designed to transmit rotational motion from transmission nodes (gearboxes, gearboxes) to wheels with a constant speed. However, it does not depend on the movement of transmission aggregates, suspension or angle of rotation of the wheels.

By design, this node consists of an internal and external hinge, which are attached to the semi-axis. The internal CV is installed in the transmission unit, and the outer wheel is in the wheel hub.

There are four main types of shruses:

• Sharic
• Thip
• Sucharicovye
• Paired cardany

Ball Sls ensures the transmission of rotation using balls that slide in special grooves in the hinge body. Thanks to its ability to transmit a large torque, a large angle of rotation and minimal backlash between the elements, this type of joints is widely used in front-wheel drive vehicles as an outer wheel hinge.

Due to the characteristics of the design, the ball screen does not compensate for the axial movement of transmission and suspension aggregates. For this serve other designs.

Tripod Sls - one of the most common types. It allows you to compensate for axial movements. In the housing of such a node there is a three-beam plug with rollers on needle bearings (tripod, three-type). This design allows axial and angular movements. In case of axial oscillations or turns, the rollers move along the guide grooves of the case. Today, such nodes are used as internal wheel drive hinges.

Sucharic (cam) Sls are susceptible to overheating, so this mechanism It is used primarily B. truckswhere the angular speed of rotation is not high.

Sprayed cardan shafts They are two hinge, which are fastened with each other. Due to this, they are compensated by mutually compensate for the uneven rotation of each other. Initially, such shruses were installed in American cars of the 20s of the last century. Later they were put in American SUVs. Today, this type of hinges is found in some models of trucks, tractors and construction equipment.

Requirements for lubrication Sls

It should be remembered that what kind of lubricant fell, it is impossible to lay in the Sls, since it depends on the resource and performance of the node. Moreover, a certain lubricant must be labzy in different hinge. For example, in ball bearings, a material is required, which has high anti-plasive properties, and in the rods do not use lubricants with solid particles (disulfide molybdenum, graphite). It should also be remembered that for external and internal lubricants should be different.

The shrussum grease should reduce friction, prevent premature wear and protect from the formation of scaling. This is due to the fact that high loads are affected by the node, including vibration and drums, which increase the load and destroy the part without proper lubrication.

If the service is not carried out in a timely manner, the transmission of the torque is reduced and an unpleasant knock appears when the steering wheel is rotated.

In addition, the lubricant must provide protection against corrosion, withstand the temperature differences and to hold well on the surfaces. Another important requirement is to reduce the cost of fuel to transmission losses.

It is also important that the lubricant is compatible with elastomers and polymers from which anthers are made. Otherwise, it will destroy the seals and water, dust and other contaminants will begin to get into the node.

Types of lubricants for Sls

Shrusov lubrication has a lot of varieties. Therefore, an unprepared car enthusiast is quite difficult to understand in all the variety of materials presented and acquire the necessary one. Among all lubricants, lithium, barium and disulfide-based molybdenum can be distinguished.

Lithium lubricants shrus

Lithium lubricants are the most common materials for servicing transmissions. They are made on the basis of mineral or synthetic basic oilwhich is thickened with lithium soap. They are characterized by good anti-corrosion, anti-promotional and anti-wear properties. Such materials are used most often in tripod hinges that require soft lubrication without solid components.

Anthers in hinges, where lithium lubricants are used should be regularly inspected for destruction. The thing is that such materials are filled with abrasive particles and destroy the node.

Many lubricants of this category are neutral to polymers and elastomers from which anthers are performed for the Sls. Nevertheless, some materials can destroy such seals. It should also not be used in lithol-24 lubricants, graphite and with Molybdenum disulfide.

Lubrication Sls with Molybdenum

With the development of technologies, lithium lubricants have become less effective. The problem was solved by adding Molybdenum disulfide into the composition. They were similar to lithium analogues. A distinctive feature was the ability to withstand high loads, as well as improved anti-corrosion properties. New lubricants also differed in better compatibility with tires and plastics from which anthers are manufactured.

Lubricants based on disulfide molybdenum are used mainly in ball hinges.

Usually complete with a new boot goes a bag with lubricant. It is not worth trusting to her, since the chance that there may be a fake is very large. Therefore, before applying lubrication, check its consistency. To do this, a certain amount of its amount to the sheet of paper. If the material is not thick enough or causes other suspicions, it is worth refrangic from its application.

The minuses of disulfide molybdenum lubricants include low water resistance. Even with a small moisture, the material turns into an abrasive, which damages the inner surface of the shruss. Therefore, when using such materials in hinges, it is necessary to regularly check the state of the sealing.

Also incorrect is the information that lubrication with the molybdenum disulfide is able to restore the damaged node. If a crunch appeared in a shrus, it means only one thing - the mechanism should be repaired or replaced.

Barium lubricants

Most of the lubricants that were created to serve shruses turned out to be ineffective or expensive. The exception of barium-based lubricants, which are worthy alternative to lithium and molybdenum lubricants. They have high lubricating properties and perfectly protect nodes from wear.

The main advantage barium lubricants lies in high water resistance. In addition, they effectively prevent corrosion, wear and education Zadira. Also, barium-based materials are fully compatible with polymers and elastomers.

The disadvantages of such lubricants are the complexity of production and high cost. The only domestic product that was distributed is SRB-4. Instead, you can buy a foreign analogue, but in this case you should be prepared for large spending.

It should also be noted the low stability of the barium lubricants to low temperatures. With the active operation of the car, it is recommended to check the condition as often as possible. lubricant And to replace it.

What lubricants should not be used?

Lubricant manufacturers claim that it is their lubricant that guarantees reliable operation of the nodes, although in reality the situation is different. For example, it is impossible to use graphite lubricant in hinges, as it is designed to maintain bearings. The service of the node, where a similar material was used will not exceed 20-25 thousand km.

In addition to graphite lubrication in hinges, it is not recommended to use hydrocarbon-based materials, such as technical vaseline. The thing is that, despite the high operational propertiesThey begin to collapse already at +45 ° C. Therefore, such materials are not suitable for working in heavy-loaded nodes.

Also in hinge should not use sodium-based lubricants or calcium. They are suitable for servicing bearings, control cables and other moving compounds, but are not intended to work in shruses and other hard-loaded nodes. It's all about their weak anti-corrosion protection. After such a lubricant, the hinges will become unsuitable after 15-30 thousand mileage kilometers.

Replacing lubricant

Replacing the lubricant in a shooter - a lesson that will require some time and skill. Nevertheless, even an inexperienced motorist is able to do this, the main thing is to respect the procedure.

First of all, it should be removed all the elements that hold the Sls: ball rods, supports. The node should be removed carefully to avoid damage. Then on the hollow case and the place of its landing should be made marks, for which the mechanism can be easily installed on a regular place.

After removing the shrus, it is necessary to disassemble and clean from the old lubricant. For this, the external and inner side node. Internal surfaces can be wiped with a dense rag or paper. It is prohibited to use soap or car supersampunk, as these tools may worsen the quality of lubrication. For such purposes there are special cleaners.

Next is the filling of the node with a new lubricant. The outside of the filling should be up to the limit. Excess lubricant should not be removed, since in the process of work it will go to the hinge. The inner part is filled with 3/4 of the volume. Then the Sls is collected back and installed on a regular place.

A small amount of lubricant must be embedded inside the anther and evenly distribute it over the surface. After all these procedures, the elements of the chassis are installed on regular places.

Remember that the service of a shruss should be carried out every 60,000 mileage kilometers, and with active operation - after 40 tons. Km.

Abbreviation Sls - this is a reduction in the phrase "hinge of equal angular velocities". In the cardan shafts of the rear-wheel drive cars, similar functions are performed, consisting of crosses and cups with needle bearings. The difference between them is only that the cross provides a much smaller than the Sls of the degree of freedom. But the cheapest Slus is much more expensive than the most expensive cross. This circumstance increases the desire to extend the service life. For which, of course, you can use good lubricant And follow the condition of the anther. Therefore, the question of what best grease For Sls, natural. Timely replacement Ripped anther will also extend the service life of the grenade if the lubricant is replaced with it.

Schlus design

At the beginning of the last century, many decar designs were developed, which is used to this day. For example, cracked or cam, cam-disk, balls with dividing grooves or with dividing levers, with spherical rollers and fork, paired cardan. All Sls have both advantages and disadvantages. The characteristics of each design is better for some conditions and are not so good for others. Therefore, there is no question what kind of design is despite.

For exterior hinges of modern fast drives passenger cars Proved better characteristics Ball cutting with 6 balls. The same amount of grooves for them has a casing of a shruss and an inner ring under a separator holding balls from a shrus. Connecting an inner ring with a drive and a casing with a hub slot. With large corners of the leading wheels, the maximum allowable transmitted torque is much less than at small. Therefore, for long-term trouble-free operation of the shruss, it is necessary to prevent its work with a large load in the extreme positions of the steering wheel. Each SCR is bent protected.

Tripoids often use internal pomegranate. They are less mobile, but more wear-resistant, as needle bearings are used in their designs.

Lubrication composition for Sls

For modern ball cutters, a grease is used, most often based on mineral oils With the content of molybdenum disulfide as an antifriction additive (from 3 to 5%). Because of the black color, it can be confused with graphite lubricantwhich in no case cannot be used in the shurts. An ordinary lithol, due to its weak antifriction qualities, can not lubricate the Slus.

For tripoids, it is impossible to use the lubricant described above. For them, you can only use a special bary-based lubricant. One of its differences is a wide temperature range in which it can work. After all, in winter, the drive cools up to -30, and in the summer he is heated to +160 ○ C.

Greased lubricants are manufactured, thickening base oil with various thickeners, which can be used by the salts of higher carboxylic acids: lithium, calcium, aluminum, sodium and others. Inorganic thickeners, such as a bentonite clay, and synthetic, for example, polytetrafluoroethylene can also be used. As a rule, the composition of the lubricant includes up to 90% of the base oil, the remaining 10% comes to the share of thickener and various additives that determine the main characteristics of the substance.

In what cases is changing the lubricant

If the drive grunted, change the lubricant in it late. You need to change the drive itself. This is explained by the fact that if the hinge clouted, it means that there is already significant development in it and how many lubricant changes in it, it will not be better from it. To determine which of the hinges stumbled, you need to choose a flat asphalt site and drive through it, turning the steering wheel to the left left, and then until the end is right. At this time, the assistant is outside the car should evaluate, in which case crunch louder. If the sound is louder when the steering wheel is turned left, then you need to change the left outdoor drive. When crunch louder when the wheels are twisted, you need to change the right external drive.

How to change the lubricant in the shurts

Proper lubricant replacement. Replacing the lubricant in the shurts is made due to its pollution after the breaking of the anther or the development of the resource, when there are many wear products in it. It is necessary to remove the old hinge lubricant completely to eliminate the possibility of increased wear of the Sls. To do this, it should be disassembled and thoroughly wipe with a clean rag. Wash it without disassembling it, it will not work, because the plastic lubricant is extremely badly washed off.

Retaining ring

With disassembly of the inner hinge, it usually does not arise difficulties, so we describe the outdoor disassembly. If you do not have a special device for removing the outer hinge, then remove the drive assembly and hold it in the tees. Remove the clamps from the anther. Removing, try not to damage them, factory usually better than those coming complete with a new boot. If the cover is torn, cut it with a knife, if not, slide it to the drive stock. Stroke a hammer through the inner ring, run a hinge from the drive. Turn the inner ring with the separator so that the holes in the separator are visible, while the axis of the symmetry of the separator and the hull will be perpendicular. With a flat screwdriver, remove all the balls from the separator. In the separator, two holes out of six are longer than others. Turn the separator so that they turn out to be pressed to the walls of the case and remove the separator with the inner ring of the housing. Featuring the position of the inner ring, remove it from the separator. You can easily remove the remnants of lubrication from the parts, and you can collect a hinge.

Insert the inner ring into the separator. Orient the separator so that the long openings in it are pressed against the hinge housing, and insert the separator with the ring inside the housing. Insert the balls into the separator holes and expand the inner ring so that the hole is located along the axis of the case. The node leaves 120 to 150 g of lubrication. How much will fit in your case depends on the size of the hinge.

To correctly fill the hinge with lubricant. Hold it in the thieves hole under the drive up. If the lubricant for it is bought by you in the tubes, then press it into the hole under the drive, pressing the tube tightly to the ring, until it seems between the separator and the case. If you have in your other package, then overlap it with a spoon and put into the hole under the drive suitable in diameter with a cylindrical subject; Criterion filling the same.

During the installation of the anther, do not stuff a lot of lubrication into it, otherwise during the work of the anther, it will tear it. Before tightening the twilight clamps, lubricate the grooves for them with lithol.

Testing lubricants

Tests included the following checks:

1. Washing out water and protection of the node from this fluid penetration into it.
2. Fluidity while increasing the temperature to 180 ○ C.
3. Lubricating properties.
4. Resistant lubricating film to pressure.
5. Metal wear protected by lubricant.

Places in the process of testing were not distributed to contestants, simply put out the estimates, so it would be better to determine which lubricant is better than you. Below are the test results plastic lubricants For ball hinges one of the independent researchers.

Correctly grease tripoid hinge

Despite the fact that the design of the tripoid hinge is the use of needle bearings, lubricate them with 158 lubricant, which is usually used for needle bearings, is strictly prohibited. The fact is that for its manufacture, a lithium thickener is used, and it can be used at a temperature not higher than 120 ○ C, and the temperature of the inner grenade reaches 160 ○ C. Since the lubricant for the inner grenade is rather liquid, it is better to pour it inside the anther installed on Drive, and then collect tripoid. You need to pour from 100 to 130 g of lubrication. More precisely, "how much?" Answer manufacturer.

One of the key mechanisms of the car is the hinge of equal angular velocities (Solus). This detail It is quite reliable, however, due to the cyclic rotating load requires timely service.

What is needed for lubrication

The use of lubricant solves a number of vital tasks for the car:

• Reduction of friction;
• Prevents premature wear of parts;
• Reduction of load in general on the part;
• Reduction of fuel costs to transmission loss;
• Corrosion prevention;

With untimely maintenance, the transmission of torque is reduced, an unpleasant knock appears when the steering turns appears.

Types of lubricants

Over time on the market, more and more different lubricants appear on the market. They differ in their composition and properties. The composition of lubricants are divided into two main categories:

1. Lithium;
2. Based on disulfide molybdenum.

Lithium lubricants

Lithium lubricants for a shrus - the most common and affordable option. Photo: a.d-cd.net

The most common type of lubricant for transmission service. Substances have a yellowish substance with excellent viscosity, which thickens at low temperatures.

Lithium compositions are characterized by high conservation properties that carry a pronounced anti-corrosion effect. It is not bad for lubricant and dust and dirt falling into the mechanism, but do not solve this problem as a whole. It follows every 40-50 thousand runs to serve the drive system.

Most lithium lubricants Neutral to polymeric materials, from which modern anthers make for the Sls.

Important: High-strength plastic on an organic basis can be dissolved by lithium compositions.

In such cases, it should be discussed in the instruction manual, in which you must be recommendations for maintenance of the Sls and the compositions used for lubrication.

• Widespread, due to low cost and sufficiently high efficiency;

• React with polymeric materials;

The following products are widespread on the market:

• Renolit;
• Hado;
• Very Lube;
• Litol-24.

Molybdenine Disulfide Based Compositions

In front of the specialists, the tasks of extension of anti-corrosion protection of parts and reducing the likelihood of entry into the reaction with polymer materials of anthemists were faced. The problem is partially solved with the use of molybdenum sulfide.

The use of compositions based on disulfide Molybdenum has become a new step in the automotive industry. Photo: Forum.rcdesign.ru.

• Increasing the stability of corrosion parts is the main feature of compositions based on molybdenum sulfide. Specialists who conducted comprehensive tests in the reports indicated that after a run in 100 thousand, signs of mechanisms wear are not manifested.
• Partial substitution of the salt of organic acids made it possible to reduce the reaction to the reaction with polymers. As a result, manufacturers recommend the use of this lubricant in almost all modern cars.

• If moisture gets inside the Sls, it can completely lose its properties, which in turn leads to the conclusion of the entire node.

IMPORTANT: It should be carefully followed by the tightness of the anther so that the lubricant does not have contact with water.

With all the advantages of the composition of this group, the replacement is still necessary to replace every 95-100 thousand mileage.

The market offers a wide range of products that differ in both quality and price. The following compounds are most often used:

• Liqui Moly.;
• Texaco;
• Mobi;
• ESSO;
• Shrew-4.

Barium lubricants

Most of the new funds are either weakly effective or too expensive in production.

An example of an alternative lubricant can be the barray, more precisely, the compositions on its basis.

• Neutrality in the reaction with moisture. In case of damage to the tightness of the anther, there is no need to replace the lubricant. Operation may continue until dirt and dust fall into the Sls.
• Neutrality in the reaction with polymers. Can be used with anthers made from any polymer material.
• Reliable protection against corrosion in extreme operating conditions (off-road, sands, etc.).

• High price. Especially concerns the well-known foreign manufacturers.
• Low frost resistance. When operating in a cold climate requires frequent periodic replacement.

Replacement of lubrication

In the process of replacement, several steps can be distinguished:

1. Disassembling the chassis of the car.

We remove all the elements holding the screen (ball rods, supports). The mechanism is removed carefully to eliminate the possibility of damage.

On the case of the Sls and the support, apply notches, which will serve as guidelines for accurate assembly (will be just combined to combine them).

1. Disassembly directly with the Sls and removal of the old composition. Separate the external and inner part. Clean the details from the old lubricant and dirt. It is enough to wipe with a dense cloth or paper.

IMPORTANT: Do not apply a car supersampoo or soap, the remains of which can worsen the quality of the lubricant. Exist special means Cleaning.

1. Filling the Sls with a new lubricant. The outer part is filled to the limit, better if the lubricant will perform. The inside cost to fill in three quarters.
2. Assembling Sls.
3. Installation on a regular place, installation of anthers. There should be a small amount of lubricant inside the anther and distribute it to the inner surface evenly.
4. Assembling the chassis of the car.

It should be noted that automakers and specialists recommend carrying out work on servicing the Sls not less than a run of 60 thousand kilometers. Manufacturers of lubricating compounds convince the buyer as their product and recommend replacing every 80-90 thousand kilometers. With active operation in difficult conditions, it should be checked running every 40 thousand runs. And on the contrary, if the car leaves the garage rarely, then the replacement can be produced at a periodicity of 4-5 years.

Video instructions for replacing a shruss lubrication you will find here:

Important features and total

When solving such an important task, you should perform several consecutive actions:

• Examine the instruction manual for the car. In this useful book, you can find all the recommendations of specialists in servicing all nodes and aggregates.
• Determine the properties of materials from which the Sls is made.
• Determine the frequency of replacement of lubricants depending on the operational loads of the car.
• It is worth calculating the means that will be spent on the purchase of lubrication.

When buying a lubricant, you should pay attention to the components contained in it. In addition to the above, there are also substances based on graphite, mineral substances, zinc, iron, etc. These products serve mainly for lubricating various types of bearings in other nodes and units.

Summarizing the result, it can be noted that the most optimal price-quality ratio is lubricants Based on Molybdenum sulfide. They have a number of advantages over the rest of the competitors and, while observing the tightness of the anther provide reliable protection Sls.

Rotational power points from car transmission nodes to wheels for aligning angular velocities, special hinges are used, called Sls and a critical lubricant.

Cars of specific brands have different kinds devices that provide the rotation of the leading semi-axes at the same speed. It does not depend on how the steering wheel is turned cool and from the position of the suspension system of the car.

Sls consists of two autonomous nodes:

• the internal node is attached directly to the leading semi-axis;
• the second is integrated into the hub of the drive wheel.

They are used to equalize the angular speed by large balls, moving along special grooves. For inner scrub and an external analog apply, depending on the auto model, specific lubrication. The lack of a mechanical design is that it does not provide axial suspension movements. Needle hinges have such properties.

They were called through the bridges, from the English word Tripod. The hinges of this species compensate for the lack of ball analogs. Alignment of the angular velocity occurs due to the movement of the rollers using special channels when reversal or axial instability.

Since the initious idea of \u200b\u200bengineers is not stiring, crews have been created with hinges of the ball mechanism, allowing you to create axial movement. As an example, it is worth leading domestic car Volga Automobile Plant Modifications 2108-2110. We were produced with a needle variant and ball.

What is required for lubrication?

It should be understood that the conversation is about the lead front bridgeBecause buildings leading bridge align the angular velocities using differential. Shrucils work under huge multidirectional power points, in an increased temperature zone. In order for the tripod to function for a long time, composite details are lubricated.

The required consistency of the pasty species is integrated into the node and is carefully sealed by reliable anthers. They can be plastic or made of rubber.

The prerequisite is never, even with a lot of need, do not use the lubricant at hand. The recommended type of lubricant will provide long-term operation of hinges.

A knot with balls of working elements is lubricated with products with universal anti-plates capable of working in the zone of elevated temperatures.

A similar condition is made for three tripods (node \u200b\u200bwith needle rollers) requiring that the lubricant does not have solid particles in the consistency structure with abrasive characteristics. The use of a non-specific lubricant product is a direct way to destroy important nodes for cars. The use of non-recommended graphite lubricants, leads to a rapid hinges output from the functional state.

Drivers make a rough error when using a lubricant intended for ball hinges for lubricating needle roller hinge.

Types of lubricant

In specialized online stores, standard trade enterprises You need to buy lubricating products with NLGI 2 abbreviation on the package.

The consistency contain anti-mailing additives MOS2 (Molybdenum Disulfide). Lubrication actively opposes hinges wear with instantaneous power influences when welding of moving balls on constructive gutters is possible. Practice showed, lubrication of the hinge ensures its long-term operation.

Recognize a lubricant containing molybdenum disulfide, easy to appearance. Consistencies are represented with black or gray-dark fold.

The lubricant packaging material contains the following inscriptions:

• for ball shrines;
• MOS2;
• with Molybdenum Disulfide;
• Schlus-4 (Lubrication of domestic production).

In retail, wholesale, there are other suggestions that deserve the attention of motorists. The main thing is to choose to mitigate the abrasiveness of the rubbing parts of the joints the desired lubrication product that is well affecting the functionality of the worker.

Lubricating materials for tripodes

The design features of the tripods, where the main wear elements are needle-type bearings, requires the use of other stamps of the lubricant product.

Practice is proved that it is better to use lubricant consistencies containing on the packaging of the inscription:

• Nlgi 1;
• NLGI 1.5;

Presented funds do not have solid addition enclosures. In the context of the instructions, it is said that it is impossible to use lubricant for this type of hinges under the SHRM-4 sign and other analogues containing molybdenum supplements in the structure.

The operational practice of cars proves that it is better to buy and use the following lubricants:

• Tripod Joints;
• "For raise";
• INBOARD;
• Inner and others.

Lubricant list is great. You are physically impossible to bring on the list available on sale. Imported lubricants are easy to buy in numerous stationary outlets and online stores. Today, the universal lubricant for the ripode is a liquid imported product due to high technological characteristics.

Lubricating products requiring detailed clarification

Liquid market platforms offer products requiring refinement where they can be used. That is, lubricants for the inner nodal element, a tripode, or apply as a universal product.

• The first in the list on the analysis is a lubricant consistency called Redline CV-2, containing molybdenum red. The instructions for use explains that the material contains molybdenum atoms organic in the molecular structure. In English, approval is accompanied by a phrase of Red Moly.

On the forums about lubrication different interpretations. Ohhh praise, what it is cool! Others get up to the front, proving that it is suitable exclusively for ball hinges. Opinions are opposite, but not critical on the emotional heat, which ultimately leads to a neutral conclusion - can be used for ball valves and for rejuvenations.

Lubrication on a distance

Advertising rollers of manufacturers of lubricants for special automotive knots, attract the attention of motorists. Of particular interest causes lubricants made on polyurea. First we decipher the complex name, that is, what it means.

These are synthetic polymers, in the structure of which contains particles of the product (urea). The substance is represented by the chemical formula of NH-CO-NH. Lubricant Polyuctural Creates a special anti-promotional protective film.

• This technology made a product SlipKote® Polyurea CV Joint. Used to lubricate nodes and parts of hinges aligning angular velocities. It is used in cars with drive leading front axle, in the cars of individual models with the rearmost bridge.

Lubricate the node for the entire service life. Change when passing. This lubricant consistency has a number of advantages over the rest of the counterparts. Lubricant is holding high temperatures, does not destroy thermoplastic, waterproof. The thickener is polyured in sublimation with basic lubricant consistencies, unconventional additive materials, guarantees durability, resistance to uncomfortable use conditions.

When using this lubricant, it is necessary to systematically control the hinges on the possibility of leakage of the liquid.

Domestic manufacturers

In North Palmir, the production of NPVTO lubrication in the range has begun. New product called "MS-Sls Tripod". The instructions for use state that the lubricant is recommended for universal use at temperature modes up to +160 C °. Dana and other positive information. Little is told about the shortcomings.

Manufacturers of lubricant NAMPATI "Forgot" in detail specifications Product. It seems that the buyer must believe the seller for the word. To some extent, the lack of a branded enterprise, buyers are not clear.

In the selling product, it is not mentioned whether lubricant has a test test. What side inclusions are integrated into the consistency? The lack of elementary descriptions of the goods cannot but disturb customers. They want to know about the domestic product of Nampavto, almost everything.

What is Sls?

The hinge of equal angular velocities (Solus) is an important detail used in front-wheel drive and all-wheel drive vehicles. Sls transmits torque from transmission to wheels, while exposed to serious shock loads; Therefore, special lubrication is necessary: \u200b\u200bit ensures the protection of the shruses from premature wear and corrosion.

What are shrurs?

Hinges of equal angular velocities are of different designs, but in modern automotive industry two main types are used. The first type is the classic "Rapt-Lebro" hinge with 6 balls. This type of shrus is now most common as outer wheel drives of front-wheel-water passenger and off-road all-wheel drive cars, less often used as internal or cardan joints. The second type is a tripod hinge having smaller angles of rotation, but allowing higher speeds and axial offsets, is mainly used as internal passenger car hinges. These two types of hinges require two absolutely of different types Lubricants.

Lubrication selection:

The ball hinge, due to very significant contact pressures, requires lubricant, depending on the load containing from 3% to 5% Molybdenum disulfide. The lubricant is made on a mineral base basis, a lithium complex soap is used as a thickener, EP additives are often added to increase the bearing capacity. The resource of such a hinge and the lubricant itself is very large and approaches the resource of the car itself, if non-rubber covers. Quite often covers are rushing due to mechanical effects. If the tip of the cover can be quickly determined, it is enough to simply change the case and lubricant, if not, the hinge itself falls under the replacement. Most manufacturers deliver in spare parts covers, along with a shruss lubricant in an impersonal plastic package, often in insufficient quantity. Sls may be needed from 40 to 90 grams of lubrication. Lubricants for shruses from various manufacturers can differ significantly from each other, both in price and properties and should not be thought that products are supplied from maximum quality. That is why Liqui Moly offers a special lubricant for LM47 LANGzeITFETT + MOS2 shrusses in separate packages 100 and 400 gr. LM47 significantly exceeds standard lubricants and is suitable for the highest load and turnover, contains additional (except for disulfide molybdenum), antisaded additives based on zinc-phosphoric compounds.

Tripod type hinge, due to elevated temperature (proximity to gearbox and design feature), require high temperature lubricant Without solid inclusions, the penetration (viscosity) of such a lubricant is slightly lower than that of the classic lubricant for shruses. The bridges use lubricant with a polyurethane thickener, first-class penetration, top temperature range up to + 180 ° C and mandatory EP-complex.

The right choice of lubricant for hinges of equal angular velocities is the key to a long service life, as well as a comfortable and secure trip.

How often to change lubricant?

Lubrication is laid at the factory for the entire service life of the hinge, but someone is not insured against surprises. A rubber or plastic casing of a shrussa can break from contact with outsiders or overheating. Then the hinge inevitably gets dirt and water. If you do not detect the problem on time, then an expensive hinge will have to be replaced and, accordingly, lay fresh lubricant into a new item. If you regularly monitor the cover covers, it is enough to simply replace the case itself and, naturally, lubricant.
