In the design of the car there are parts and devices that provide protection against instability, from light tipping in case of sharp turn. Stabilizer racks are devices designed to create transverse stability car. Therefore, they are called transverse stability stabilizer racks. These are important elements of the machine design, so you need to follow, be able to determine the faults, what problems and in which node.
Front stabilizer
Consider the first thing that such a stabilizer is and what is it needed for? The transverse stability stabilizer serves to reduce the horizontal roll of the car body during turns and sharp maneuvers. The stabilizer itself is attached to the body with a stabilizer racks. The design of the racks is designed in such a way that the stabilizer can move depending on different loads. Auto pendants are different and also racks are made of different types.
Device and principle of operation
The rack is a rod of 5 to 20 centimeters long. From both ends, the rod has hinges for mobility. As hinged connections, the following options can be installed:
- two ball hinge;
- hinge and stabilizer bushing;
- two sleeves;
- on the one hand, the hinge, and on the other - the thread.
As a rule, hinged parts are welded with a rod with a right angle (90 degrees). At the site of the tip of the tip to the rod made of metal has a cervix (thin end). It was done specifically, that is, weeding the structures in this place so that when the allowed MAX loads is exceeded, the device's rack broke down in a refined place. This method can be called a mechanical fuse. If the rack broke in another place, it could break through the bottom of the car, harm the driver or passengers.
Such a well-thought-out design of racks allows you to protect against unnecessary problems. Do not complain that racks often fail, they are specifically made not too thick. Not the original racks in diameter are more often greater than the original. They will last longer, but the safety in this case is reduced.
The most popular desks are racks with ball hinges. The device of this type of rack includes a ball finger made of steel and a landing plastic space with a lubricant having special temperature and dynamic characteristics. The cover from metal or plastic is pressed on the finger on top.
To protect against dust in hinged compounds, sealed rubber anthers with lubrication are always installed. Such a simple detail, like a boot, significantly increases the life of the device and the movable mechanism protects against loss and lubrication. The main property of lubrication for hinges under the boot is frost resistance, so as not to thick in strong frosts.
For a better understanding, how the stabilizer racks work, it is necessary to understand that the racks are connected to the stabilizers not rigidly, that is, they have some mobility relative to each other. During turning, the machine begins to bend (natural roll) and at this time there are alone forces on the car body, and the forces are affected by the suspension that are trying to straighten the body. If the roll strength is much more, that is, the risk of breakdowns of conjugate details: stabilizers and eyelets of the hub. It turns out that the stabilizer rack is a damper that aligns oppositely directional forces. But, since the power that wants to overturn the car (with a sharp turn) and the force, which is against it, both pressing the stabilizer rack, because of which the hinge compounds of the rack are gradually destroyed.
There are manufacturers that make stabilizer racks with self-adjustable. For example, an electronic transverse stability stabilizer is installed on the Nissan Patrol GR (Nissan Patrol of Ji ER), that is, the electronics can turn off the stabilizer.
There are still cars, more often off-road vehicles who have the work of stabilizers are regulated electronic block Management (ECU).
Faults of stabilizer racks
Malfunctions can be determined, knowing the symptoms, signs of incorrect operation. If troubleshooting in the work of stabilizative racks, the following features appear:
- During the movement roven road There is a characteristic knock. This sign is on the machines on which racks with ball hinges are installed. For example, the stabilizer is knocking when moving a "lying policeman" (artificially created irregularity of the road to reduce speed).
- During the movement along the smooth road, the car pulls it left, then right.
- During the usual turn, the car rolls (leans) more than it was.
- There is a transverse swinging of the body of the car when moving along a flat road.
Causes of stabilizer racks
The most vulnerable element in this node is hinged connections. The reasons may be the following:
- The boot was broken, because of which the dust enters lubricant and the connection itself.
- The ball of the ball finger is erased. In this case, the ball finger dangles in the seating.
Repair racks is a complex process. For this you need factory good equipment. You can simply replace the worn item, the finger of the ball or sleeve. The cost of such works is high. Therefore, it is better to buy new stabilizers. It is not necessary to buy original, you can buy ordinary, they also work well.
How to check the stabilizer racks
To find out what state is the racks with ball hinges can be very simple:
If the machine installed stabilizers not with balls, but with sleeves, then check even easier. It is enough to see if the tires did not wear only on the one hand. If the rubber is worn out, replacement is required. Rubber wear is better to check when the wheels are pumped. See for your concrete brand and auto models. Mostly for passenger carsPressure is set by 1.9-2 atmospheres.
To save money, you should not immediately go to service service station and carry out paid diagnostics. Some light diagnostic techniques can be held yourself. In addition, not all people are honest, can exaggerate and replace not what you need.
How to change the stabilizer racks
To learn how to change these racks, it is enough to make a replacement once as an assistant. Obviously, depending on the brands and auto models, the design and methods of replacement are slightly different.
Required tools for replacing stabilizer racks:
- jack;
- keys;
- hexagons;
- mount.
Front racks are longer than rear. You should not change only one rack, you need to change or both front, or both rear.
During the replacement, the axis of the machine should be suspended and loaded, that is, after raising the jack and the removal of the wheel, under ball support It is necessary to put a stand. In this case, the rack and the stabilizer will be in a relaxed state.
During the repair, you need to be careful with anthers, not to break them. If you require replacement, it is better to replace them right away.
What racks choose
Now you can buy plastic stabilizer racks. They have less strength, destroyed if they do not harm other parts and passengers of the car.
An important role in choosing the racks is played. You should pay attention to the length. You also need to look at the packaging, it is written for what machines they are suitable. Stabilizers and stands are interchangeable in models of one brand, for example, for Ford Focus (Ford Focus), Ford Fiesta. (Ford Fiesta), Ford Escort (Ford Escort), Ford Ka (Ford Ka) 1995-2001 These details are interchangeable and suitable for each other.
Rating stabilizative racks
Below we give a list of rates of stabilizers by rating:
- LemForder (Lemforder). Country: France. Such racks are purchased from them General Motors, Mitsubishi, Toyota, Opel, Volkswagen, Mersedes-Benz, Audi, BMW, Ford, Volvo, Fiat and some other brands. Authoritative quality and good resource.
Beginner motorists have a question, for which the stabilizer racks are needed, every time you have to change them - and it has to do it quite often. At first glance, it seems that the item is absolutely superfluous, designed exclusively to pull the nerves and money from a person.
Some car owners are in no hurry to change them even with the obvious signs of the wear of the racks. And make a mistake! Of course, some time can be riding with violations in them.
However, noticeable inconveniences are immediately beginning: the car is worse than the steering wheel, it shook it with and lies on turns. In addition, when the racks are faults gradually come out of equilibrium and other details of the chassis, the car begins to grow and rigidly bounce on Ughab and hubbugs (as a result, you go like a washing board, and who will like it).
For which the racks of the transverse stability stabilizer are quite clearly explained by their very very name. Let us turn to the theory and practice of replacement and finding the reasons for the output of these parts details.
Purpose: Suspension - a node is very multi-storey. Among other parts, the stabilizer is included in its kit, which is responsible for reducing the roll of the entire car in turns, holding the line of movement during disks and the absence of braking during braking. In addition, the racks significantly reduce the rocking of the machine in motion.
The racks are part of the stabilizer hosting the most experienced loads. They, as it were, connect the suspension and body into a single whole.
Causes of the cost of racks
Clearly, that with the loads that fall on their share, the racks still beanly wear out. Another thing is that on our roads they break sooner, as, however, the remaining components of the suspension. The main reason is the quality of the canvas. The chassis, designed for mileage at 100,000 kilometers of European roads, on our starts raging at best after 50,000.
The second reason is subjective: Driving abilities of the one behind the wheel. The more experienced driver and the softer handles with his car, the longer the suspension, the stabilizer and its racks serve.
Signs of need for replacement
The resulting rack manifests itself unequivocally. You should react to:
- very characteristic tapping in motion. It is very clearly heard when driving around Ughabam or turns, well, or;
- cARE OF WILL MACHINE (for example,). Many experienced drivers are so checking the wear of the racks: they are released for a few seconds a ram. However, this figure may also testify to the unequal pumping of the skates, and on other faults (for example,);
- one side of the car sat down to asphalt just lower than the second;
- swing at speed, when braking or again in turns.
Checking racks
A pair of simple methods that will help you determine the racks without resorting to the services of auto mechanics.
Turn the wheel to the left or right to full stop. Take the rack in the wheel niche and all the power pull it back and forth. You should not be afraid to break it, it usually takes on much more serious loads. A knock or a rack is heard at least a little - forward, repair is needed. The second is checked similarly after the wheel is output in the opposite direction.
If there is a pit, you can do otherwise. Twist the nut from below, the rack is released and again stretches in different directions. If the hinges do not have a stubborn resistance and the action are accompanied by the same knock - the withdrawal is clear. The second rack is checked without twisting with her nuts. Without returning to the place already removed, you swing the car for the stabilizer and listen to what the fixed rack will say. If you knock, you will have to buy both.
The suspension stabilization system is necessary in any car. Moreover, such a system should be in the front and rear suspension. Another thing is how it is structurally performed.
In passenger cars, a transverse stability stabilizer is used. On the front suspension, its presence is necessarily. It is difficult to remember the brand of the car, where the stabilizer was not installed.
But on the rear suspension can be different variants, in particular, on the old domestic models of cars. For example, in VAZ classic The role of the stabilizer is performed by jet thrust. On "Volga" rear suspension represents rear axle On the springs, the stabilizer as such appeared only on GAZ-31105. But now the release of "Volga" ceased.
Stabilizer transverse stability a passenger car It is a long and straight rail rod with rounded edges. Its length is usually a little less than the width of the car itself. On both sides of the rod there are eyeles for fastening stabilizer racks. In turn, the stabilizer racks with another side are connected to the swivel fists (on the front suspension). The stabilizer is usually attached to the front beam with two clamps through rubber silent blocks. The rod is made of high strength spring steel. By itself, it is very durable, as it works on large loads.
For which the transverse stability stabilizer is intended
The word "stabilizer" speaks for itself. Due to the stabilizer, the car confidently feels consistently on the road, it does not wind from side to side. Especially the value of the iron rod increases when the machine is moving on steep turns at high speed, when there is a risk of flying from the road and even turn over. Of course, the stabilizer is not that item, without which it is generally impossible to touch the place, but it is rather problematic without it.
Stabilizer's pole
Stabilizer racks play a role in a steady movement of the car on the way no less than the stabilizer itself. Without them, iron rods like zero without a stick - nothing means. Therefore, rack malfunctions also adversely affect the safety of motion.
Stabilizer stand can be constructively performed in different ways. The most common view is a thin rod with two hinges at the ends, outwardly reminds steering cravings. Often you can hear the expressions: the stabilizer traction, the stabilizer bracket, the stabilizer bone, but the point does not change. We are talking about the same device. If you return to the same "classic", then on the front suspension, there are several other shape racks. There are no hinges - a simple rod with a carving at both ends. The role of hinge perform rubber bushings. On some foreign cars, the stabilizer racks with hinges, but made of plastic. True, plastic is very durable.
Like steering tips, the stabilizer racks can be symmetrical and asymmetric. Asymmetrical racks are suitable only for their part. That is, the left traction of the stabilizer is only suitable on the left side, and the right hand is on the right.
Faults of stabilizer racks
There are characteristic signs in the behavior of the car on the road, on which it can be assumed that the stabilizer racks are faulty:
- - the car is unstable when driving, especially on sharp turns,
- - Rocks the car at turning steering,
- - when passing uneven areas of the road in the suspension, a knock is heard,
- - the car takes to the side if you release the steering wheel.
To come into disrepair of the shock absorber rack can for several reasons. Racks are considered consumables, they must be changed through a certain amount of kilometers traveled - approximately after 20 thousand. These parts are high load, and are subject to rapid natural wear.
The stabilizer racks fail because of the poor condition of the roads, due to the hindrance to the obstacle and when hitting.
If suspicions clusted that the stabilizer thrust is faulty, they are not difficult to check in three simple ways. Generally, B. this case We are talking about the front stabilizer racks.
1. The car needs to stop unscrew the wheels in any direction. Holding your hand for the rack of the stabilizer, with the effort to pull it. Even with the definition of a small backlash, the part is to be replaced - under the load when moving the backlash is more noticeable.
2. From any side, the stabilizer stand is disconnected (for example, from swivel fist), I do not need to remove it. Turning the item from side to the side, check on the backlash and free rotation. The more detail wear, the easier it is rotated. To check the second rack, it is enough to swing the car vertically. Bad rack will make a knock. For such an examination, we need an observation pit.
3. In this case, too, without a pit, it is not necessary for two people - one driving, the other in the pit. Who is driving - rushes on the car back and forth, who is below - applies hand to the stabilizer rack. At the time of touching the car from a place in his hand will be felt. Execution participants should be careful to avoid injury.
When the car moves in turns, its body leans to the side. The angle of inclination, correctly called the angle of the roll, depends on the size of the centrifugal force, as well as from the design and elasticity of the suspension. On the left and right elements of the suspension, the load can be distributed equally, and then the roll angle will decrease. An element transmitting force from one rack or from one springs to another is the stabilizer. Details about the device of such stabilizers are told on. Their design, in theory, consists of an elastic bracket and two cras. And the thrust is also called "racks".

Varieties of stabilizer racks
Racks (traction, links) can be completely symmetric (Fig. 1). Then they can "turn over", as well as rearrange from left to right. In the design of most cars used asymmetric racks, which, however, rearrange from left to right is allowed. And the most "complicated" option is when the left and right racks are different (not shown in the photo).
It is clear that the most vulnerable part of the stabilizer is its racks (traction). In some cars, their resource is 20 thousand km. Inspection and verification of these parts are recommended more often - every 10 thousand km. But the breakage may occur in the middle of this interval.
When replacing the threaded connections need to be processed machine oil. Well, driving parts, that is, bushings and axes, it is better to cover with a layer of cyatima-201 or lithol. But know that for rubber bushings does not fit this option. There is a special lubricant, or it is missing at all.
What is the stabilizer rack, was fully explained, but where to search for them in the car, consider it right now.
Replacement of stabilizer racks in BMW E39 do it yourself
Stabilizer stand, or rather the stabilizer racks are important details included in the car suspension. They have quite a lot of names and titles - stabilizer racks, bones, stabilizer traction and even ... Links! In the catalogs I. technical guidelines The first name is most often applied - it is considered the most correct and professional. But those who call the Stabilizer Stabilizer, clearly demonstrate some "no-formation" and ignorance. The rack cannot be called a link, as a last resort, you can say "Link". It will be true because it comes from the English. Link is a link, connection, connection.
What are the stabilizer racks?
The function of the stabilizer racks is to ensure the connection of the transverse stability stabilizer with suspension elements (for example, levers and shock absorbers). The presence of such a connection increases the resistance of the car to the side rolls and improves the responsiveness of the suspension when driving around the uneven road. According to the stabilizer stand design, it can be different - it is a pin with ballpoints along the edges, and an element with two eyeles and silent blocks in them. There are several more execution options, but the functions performed remain the same.
Faults of stabilizer racks and their consequences
In the process of operation of the stabilizer rack, huge dynamic loads are experiencing. Due to its connection with the suspension, most of the energy of the blows when driving around Ughabam and unevenness is perceived by racks. On the technical condition and service life, of course, affects the manner of driving owner, but quality road coatperhaps the main harmful factor.
Stabilizer's pole modern cars Theoretically can "walk" about 100 thousand km run, but in our realities they rarely reach up to 50 thousand km. Signs of fault racks of the stabilizer are pretty visual and tangible:
- unpleasant and obsessive tapping in the front suspension when driving on an uneven road or turning;
- excessive routing of the car when turning;
- algae car aside when driving on a flat road;
Not all of the listed features definitely talk about problems with racks, but each of the signs should be a reason to appeal to the car service - as this is not the normal behavior of the car. In principle, you can try to pre-check the status of the stabilizer racks yourself. For this you need to park the steering wheel in each of the sides and, holding the stabilizer rack, shake out of the side to the side. Tangible beating and backlash will indicate the need to replace!
Soothes in this situation only one thing - the cost of racks and services for their replacement is quite low. Purchase original details Or high-quality analogs will not hit your budget.
