S Tronic Difference from DSG. "Audi" introduced a new generation of the "S Tronic" box. And Option C-Tronic For Audi A7 Sportsback is also equipped with a wet clutch knot

The premium segment of cars is distinguished not only by the exquisite appearance and the highest level of comfort, but also design innovations. S-Tronic is a modern checkpoint installed on such a segment, in particular, on the car "Large German Troika" Audi.

S-tronic - what it is

Transmission is an essential component of the car. There are many varieties of automatic boxes on the market. These nodes around the world are gaining increasing popularity. It is from the correct work of this detail in many ways the ability of the car to move, as well as the comfort of the driver itself and the safety of motion. One of the most modern destinations in the development of new devices is considered to create robotic preselective nodes in combination with an electronic control unit.

The concept predictive S-Tronic means that the next gear (no matter is: the lower or top) is already included by the system, which is much enhanced by driving comfort, increases the dynamics of overclocking, and also consistently saves fuel.

One of the most progressive is the device with two clutches of the AS TRONIC gearbox. This unit is a further logical continuation of the DSG system from German VAG, which also includes Audi. However, this unit is its own development of the company with a support only on the principle of operation and the layout of its "junior" fellow. This node consists of several parts (which differs from other automatic transmissions):

  1. The electronic control unit of the automatic transmission S Tronic is a mass of a variety of sensors and a single block, which synchronizes the operation of the shafts and clips during the movement of the car. This electronic block of the system is the most important part, since it is the electronic algorithm that allows you to quickly and adequately switch transmissions. In this case, this part is one of the most expensive in repair. S-Tronic sensors are constantly signaling and sent to the main unit of the mass of information about the road atmosphere, speed, motor parameters, driver riding style and other indicators that allow the system to quickly adapt. In addition, the cost of this unit at the failure is quite high. However, in the absence of mechanical damage to the block of the system, the problem with it occurs not often.
  2. The clutch of the unit - 2 clutches are installed in this box that work asynchronously. One is responsible for the inclusion of even gear, the second odd. Thus, smoothness and high switching speed is achieved, which is less than 1 second. The data of the nodes is managed by an electronic control unit.
  3. S-Tronic aggregate shafts perform mechanical work inside the box by moving torque and clutch control. Also in the unit there is a hydraulicone, which is responsible for working pressure within the transmission. In low-cost versions of this type of robotic box, an electrical analogue is installed, which is less effective in its indicators. The operation of this unit also manages the electronic unit.

This system allows you to simplify the process of controlling the car, as well as save fuel, besides, such boxes are easily "digesting" a large torque in contrast, for example, from non-dusty competitors (variastors), which allows you to aggregative them with powerful engines of the Audi line. The system has received the most more distribution in conjunction with the Audi A6C model of the Tronik, which made it possible to significantly increase the total sales.

Important! Despite the entire high-tech S-Tronic unit, this system is expensive both in the acquisition and subsequently maintenance, but only the presence of a robot will fully disclose the potential of powerful German engines. This S-Tronic unit is very complicated in its design.

Pros and Cons S-Tronic gearbox

Like any complex unit, such a box has both its advantages and cons. The positive features of the S Tronic Audi A6 C7 system include:

  1. Fast change of aggregate gear due to the constructive features of the transmission and the operation of the electronic unit. The average reaction time of the unit, both when switching to the upper and lower steps, is about 0.7 seconds.
  2. Significant fuel economy of the unit in comparison with competitors. Based on the design of the system itself, in fact such a box is mechanical with an electronic control unit, which squeezes the clutch independently (one of two) and switches the transmission. This allows you to reduce fuel consumption, regardless of the class of the car, by an average of 15-18%, which also depends on the correct operation of the S-TRONIC electronic unit.
  3. Dynamics of acceleration of the car. Given the time of the reaction of the box when switching, the dynamics of overclocking up to 100 km / h does not differ from mechanical competitors and is quite superior to automatic analogs - hydrotransframes and variators. In aggregate with powerful engines, the difference with the bridge from the classic automaton lies in a more dynamic acceleration.

Despite the technological advantage of the box and indisputable positive parties, this box has negative features that can become an obstacle to the acquisition of the aggregate for some category of owners. These include:

  1. Uncomfortable switching of the unit in traffic jams. This feature also comes from the design. When moving at low speed, a long time, the S-Tronic clutch can overheat that when switching can lead to shocks, kicks, as well as to chaotic "jumping" from 1 to 2 transmission.
  2. In comparison with competitors, a smaller resource of the main parts of the system and, above all, the clutch, which some drivers have to be changed even before reaching 100 thousand km of run. Constructors are constantly improving the unit and this part of the system, but at the moment at the general level of reliability, a robotic box with a threshing Audi has certain problems with long-term reliability.

Important! When choosing a used car with such a gearbox, close attention should be paid to the unit defecting, as often such cars are sold with problem boxes.

Differences S-Tronic and DSG

Constructive aggregates of the S-Tronic and DSG system are very similar, but there is a single significant difference - in the block of the PPC itself, DSG has a less reliable electrobelle, and the product from the Audi works hydraulicock. These devices adjust the oil pressure and line up the algorithm when the signals are applied from the control device. The hydraulicock of the system is considered a more complex and perfect design, while its reliability is tested not only by the driving tests, but also practice. Cases of failure of the unit of this node in practice are single and most often occur when the system itself is incorrect.

S-Tronic Adaptation

Another advantage of this unit is the training mode of the box itself. The electronic unit of the unit control, accumulating information about the driver's ride manner using various sensors, is trying to adapt to his manner. In certain cases, this is expressed:

  • with an aggressive driving style of Dronic automatic transmission, after passing the training program, it will be faster to fasten the right upper gear, this will affect both the sensations of overclocking dynamics and comfort;
  • with calm movement, mainly in traffic jams, the box will try to drive on low gear as long as possible to avoid pinks.

The system learning mode is counted at the time of the engine start. One cycle takes 8-10 such launches.

S-Tronic Diagnostics

The diagnosis of such a gearbox must be engaged only in the certified service. Given the technological complexity of the unit, checking the state of all systems is carried out in several stages:

  1. Checking the electronic unit control unit for various errors is carried out using only certified equipment. This diagnostics helps to identify various errors, find out the state of most sensors and components of the PPC.
  2. The diagnosis of the mechanical part of the S-Tronic is most often carried out when the symptoms of the malfunction are comprehensively together with electronic check. This method involves the opening of the CAT body, inspection and defecting the components.

Important! You should not check this equipment using primitive scanners to read errors. The incorrect operation of the scanners may not identify most problems, and the electronic block of the box will record the wrong signals, which can lead not only to the loss of the warranty, but also to problems with the electronic part of the box.

S-Tronic Reliability

The reliability of the S-Tronic system will fully depend on the operating conditions and the driving manner of the owner. Thus, with large track runs, a frequent change of high-quality oil on the original and low loads, such an aggregate is fully capable of going out by the rules of mileage of 200 thousand km.

However, in the practice of such a regime it is possible to achieve not always. According to most professionals, this type of box is the least reliable among all automatic competitors, although every year the designers make a lot of changes that improve its endurance. After 5-7 years, according to the results of these upgrades, this type of S-Tronic is equal in terms of reliability indicators with the most endless aggregates of the type of variator and the torque converter.

S-Tronic Resource

The resource announced by the manufacturer of this system is 200,000 km. However, adhering to the regulatory replacement of oil in 60,000 km and combining aggressive ride, it is almost impossible to achieve such an indicator. Separate elements of S-Tronic as a result of faults can manifest on 100 thousand km of run, and overhaul most often overtakes such boxes of 150 thousand. To extend the life, the aggregate must often change the transmission oil and move as much as possible in traffic jams, thereby not allowing the overheating of the system.

S-Tronic Malfunctions

Typical malfunctions due to violation of the rules of operation or design features are as follows:

  1. Cleaning wear from overheating, increased loads, disorders of the electronic algorithm. Such a problem occurs on this unit most often. At the same time, the S-Tronic clutch replacement is the fiscal operation on this type of checkpoint, on average, such an operation will cost the owner of about 60-70 thousand rubles.
  2. The failure of the electronic block S-Tronic, shafts as a result of the distance to the action. Loosening of sensors, moisture entering, as well as mechanical damage to the electronic block S-Tronic can lead to failure of the entire unit. Such a problem in S-Tronic requires professional intervention and large pillows, as it is often the replacement is not only the block itself, but also many sensors.
  3. Tschi hull and S-Tronic glands. Such a problem is quite rare, most often due to the use of poor-quality transmission or mechanical damage to the hull itself. However, with oil starvation of the S-Tronic system, the entire unit may fail and cannot be regenerate. The cost of such a gearbox assembly is about 400-600 thousand rubles.

Conclusion

S -tronic is a technologically perfect CAT for the aggregate of all positive and negative qualities, which, with proper operation, will give the owner a lot of positive emotions.


The seven-step gearbox "S Tronic" The company "Audi" appeared quite recently, but we have already time to try it in the recent "Audi A3" test (Claxon No. 11 '2008). And now the invitation to the presentation of another device with seven gears is fundamentally new. If earlier, similar aggregates were offered only for models with a transverse engine location, the new box is designed for the longitudinal circuit.

The German town of Baden-Baden is known, first of all, as a resort with thermal waters, as well as its famous casino. Another attraction - Located in the suburb of the Test Polygon "Audi", where we had to test the new seven-step "S Tronic", installed on the 349-strong coupe "Audi S5".

The presentation of the device unexpectedly started at all designers, and marketers who put a question quite globally: why do you need such boxes? As it turned out, the usual "mechanic" is less suitable for buyers even in the old world, where drivers used to combine savings on aggregates with an active ride. The average age of consumers is increasing, the number of cars is growing rapidly, and the speed of movement in large cities, on the contrary, is constantly decreasing. In such conditions, drivers would like to see the gearbox as fast as "mechanics", and as comfortable as "automatic" so that it can be controlled by both manual and automatic mode. One of the solutions of this problem is just two clutches.

The principle of operation of the new box remained the same as all "robots" of the family "s Tronic" and DSG. Recall that in such aggregates, two multi-disc clutch couplings operating each with their transfer - even and odd are involved at once. Suppose until the car accelerates on the second gear, the automation connects the third stage in advance. The transmission themselves are switched by opening one clutch and turn on the other. All this takes the hundredths of a second, and the driver subjectively feels a continuous stream of power without any delays and jerks.

From his seven-step fellow of the first generation, the new "S Tronic" differs not only by the longitudinal location. If the predecessor has the usual "dry" clutch, like "mechanics", the new box uses the so-called "wet" clutch, which is filled with special oil for lubrication and cooling working surfaces. Hydraulic drives are also used to change gears. By the way, well-known six-speed "estrins" with cross-arrangement also operate on the "wet" scheme.

Another feature of the new aggregate is two independent oil systems. The first circuit nourishes two-disc clutch, electronic-mechanical module "Mechatronic" and oil pump. The second system provides grease between two differentials - mid-scene and front axles. This made it possible to make the design more reliable.

The box is distinguished by enviable characteristics: it is designed to rotate the speed of up to 9.000 rpm and "digest" torque up to 550 nm. The first six gears are made closest, the seventh, on the contrary, "stretched" for greater efficiency and reducing the number of revolutions. By summing up all of the above - the unit is designed for cars with powerful high-speed engines with a longitudinal location and "Quattro" transmission.

Slip circles

To admit, we expected that acquaintance with a new gearbox smoothly turn into a presentation of a new modification of a powerful coupe "Audi S5", which used to be available only with "mechanics". I must say that such a decision suggested a long time ago. This is definitely the luxury coupe is intended primarily for enjoying all types of driving - from aggressive to ease-relaxed. So the possibilities of the new box as it is impossible to suit the concept of the car.

However, the organizers did not make any official statements on this account. Say, we now consider this car only as a running platform for displaying "S Tronic". However, from unofficial sources it is already known that in Europe, the sale of such a modification should begin at the end of this year.

While the machines tested the previous group, the track was dry, but closer to our arrows above the polygon charged a serious rain, so we had to test the car in more difficult conditions - with worse visibility and wet road. While I am waiting for a hub flag, I translate the button on the front panel control of the engine settings, gearbox and steering wheel in Dynamic mode.

Start. Without the slightest hint of slipping "ESKA" rushed forward, like a stone, beaten out of slingshot. Now the engine is configured to maintain higher speed, the box is not in a hurry with the switching, and the steering wheel as if he flooded. But ... there is no special extreme. Yes, everything is fast, even very, but somehow quite right and even comfortable, despite the slippery asphalt under the wheels.

The power supply of "S 5" is enough for the sharpest acceleration when leaving the aggregates. If you want to feel more involved in control, you can manually decline the transmission using stealless switches or box levers. By the way, if, say, twice the petal of the selector down, then the box still sequentially moves all the programs, and will not jump at once to two steps. But it will still be faster than if the average driver switched using "mechanics".

After some time, it is boring to have fun with manual switching, especially when you start to understand that the smart electronics is practically not inferior in the speed of your fingers. It seems that most drivers, "tagging" with a manual selector, will soon prefer to put the lever on the automatic mode.

But now for comparison, click the "Comfort" button, switches the electronics into more "relaxed" mode. Such a feeling seemed to be 50 "horses" under the hood under the hood, passing nuts in the steering control. Transfer began to switch significantly later, and the steering wheel became more "blurred." But only in comparison with the same "Eskaya". Against the background of many other powerful cars, this car even in the "comfortable" mode looks very sporty and collected. But still, it seems to me, to press this button will except that very phlegmatic drivers, which, in principle, do not need a similar car. And the "comfortable" settings are just a tribute to marketing, in order to further expand the circle of potential buyers. After all, even in the "Dynamic" mode, the car remains very obedient and predictable.

This modification "Audi S5" is not long to remain the first car with a new seven-step box "s Tronic". It is expected that the family will soon include an updated "S4" and a completely new crossover "Q5". In the near future, such boxes may be equipped with the following generations of "A4" models, "A5" and "A6".

Modern European car brands for improving the safety of movement are equipped with a preselective box, thanks to which improved speed indicators are noted. This unit is worthy of a worthy competition with other well-known species of the CAT.

S-Tronic gearbox. What it is?

S-Tronic gearbox in section

S-Tronic is a kind of robotic gearboxes. Also, it is called preselative box. As a rule, this transmission occurs on machines with full and front-wheel drive. It has two clutches, thereby ensuring operational switching of steps without loss of power.

The design of this box is highly reliable. It is distinguished by small overall dimensions. It is designed for 7 feet, there is a computer control system. Thanks to this, it is possible to track all the parameters of the box. There are hydraulic drives necessary to carry out shifting. The hydraulic module or mechatronics is responsible for synchronizing the clutch operation, as well as the speeds of primary shafts.

Distinctive features of cars that are completed with the bronix:

  • there is an improved transport dynamics on the carriageway;
  • speeding modes are changed instantly;
  • fast start;
  • savings in terms of fuel consumption.

Change the transmission oil on this transmission is recommended in a specialized service. Its crankcase is designed for 6 liters of fuel.

Many popular German car brands are equipped with a S-Tronic gearbox. In particular, it is Volkswagen, Audi. In a number of modifications of data, a car can occur (a type of automatic transmission) can occur. Its construction includes reliable auto parts, the work of which has a positive effect on the handling of the vehicle. They provide a decrease in fuel spending for each km. Also, feature Tiptronic The fact that there is a manual control. The machine, equipped with this box, is more efficiently moving around rough terrain.

Thus, thanks to the above-listed sides of the preselative CP, on cars that are equipped with a potential consumer demand. When changing high-speed modes, jerks and delays do not occur, the most comfortable movement is ensured.

What can the problems predictive box be expressed?

The need for diagnostic and repair work

The main reason for the occurrence of problems with the functioning preselective box is the absence from the driver of proper care. Its service costs the car owner is expensive. As the components of the KP parts are worn, it is expected to be heard from its part, noises. As a rule, the data of manifestations are noted clearly when moving from medium speeds to higher.

With the active operation of the car in severe conditions of rough terrain, increased fuel consumption may be occurred against the background of slowing the reaction to the speed change. Repair S-Tronic in this case is required. Its diagnosis should be carried out with the help of specialized programs, equipment. This seems possible to accurately determine the nature of the problem. After that, you can proceed to the removal of the box and its defect.

The car with such a box requires a regular oil change. This procedure is usually carried out once in 40000 (50,000) km of mileage. At the same time, it is necessary to remove the crankcase protection, unscrew the drain plug, then the empty container is set, where the spent transmission fluid will be flushed. Adding a fuel occurs through a sapun with a refueling syringe. Use original types of oils with optimal viscosity.

Replacing the clutch may be needed after 30000 km. To do this, dismantle the box. It should be armed with a set of clutch tools. All shafts need verification. As a rule, if the clutch has a breakdown, proceedings and characteristic vibrations are noted because of this. It is recommended to purchase branded spare parts necessary for repairing the box (filter element, pallet laying, etc.).

In such a way that the installed mechanisms in the engine compartment function for a long time, the driver needs to use high-quality fuel, check its condition, not neglected by visiting the stations, then, the timely service of the car.

Adaptation of the high-speed box

Repair S-Tronic is necessary if there are shocks (strikes) when switching transmissions, the vehicle has become worse than accelerated. In some cases, normalize the functioning of the box allows special adaptation. This procedure is relevant after conducting planned repair work and begins with a clutch check, mechatronics. Also, adaptation is needed in motion.

Adaptation contributes to the extension of the life of this box. The need for this procedure occurs every 15,000 km of run. Deviations from normal operation can be marked at this temporary gap. In particular, the car can start twice when switching speeds.

Thus, the S-Tronic box contributes to elevated comfort when making movement. Thanks to its features of its functioning, the operation of the vehicle is simplified, the system can signal in a timely manner on the presence of breakage in the box, therefore, the cost of maintaining this unit is reduced. The S-Tronic Adaptation allows you to solve a number of faults available in the automotive system.

If you are going to buy or already you are the owner of a car with a robotic preselative PPP DSG. or S-TronicThat, for sure, already persistent about the different sides of these aggregates, both positive and negative. It is impossible to definitely say that DSG. - Evil and it is necessary to avoid cars with this type of checkpoint.

DSG (from it. DirektschaltGetriebee or eng. Direct Shift Gearbox) - a family of preselective robotic transmissions with double clutches installed on Cars of Concern Vag (Audi, Volkswagen, Skoda, Seat). In general understanding, users are accustomed to sharing these boxes on 6-speed (DSG6) and 7-speed (DSG7), as well as on gearbox with dry and wet clutches. The classification is generally true, but there are a number of nuances that should be considered when choosing a car, since not everything is as easy as it may seem.

How is S-Tronic Audi different from DSG Volkswagen / Skoda / SEAT? - Nothing, with the exception of longitudinally located boxes 0B5, 0CK / 0CL and 0CJ, which are installed only on AUDI.

Also you could hear the scary word of mechatronic (Mechatronic) is the same hydraulicone. What are mechatronics and what do they differ? Mechatronics is an electron-hydraulic control unit of the KP. Perhaps the most important, but at the same time the most unreliable knot throughout the transmission. Each DSG type has its own type of mechatronics. Mechatronics from different types of DSG are not interchangeable. Moreover, for some types of DSG there are several generations of mechatronics, which also differ from each other. And for each type and generation of mechatronics, there are many versions of software designed for various engines and different gear ratios in KP. In some cases, the mechatronics of the same type can be reprogrammed (reflash) to install on different cars.

An unambiguous answer to this question, which DSG is more reliable - does not exist. Each DSG has its advantages and disadvantages. The duration of "life" of any DSG in most part depends on the conditions of its operation: all DSG do not like overheating, it usually concerns a DSG with "dry" clutches in which the mechatronics has a separate oil circuit and no cooling. For those who every day for several hours spend in traffic jams, the chances of coming to replace the mechatronics more than those who are mainly driving on the highway. Fans "light", the probability of replacing the clutch and differential, is much higher than those who prefer a quiet ride.

So, there are 7 main variations of DSG robots (including S-Tronic):

The Volkswagen concern began its work on the creation of preselective automatic checkpoints in the first half of the 80s of the last century. In 2002, the developed box of S -tronic with a pair of clutch debuted in serial production. During this time, this unit is significantly improved and improved, and even its new generations due to a long periodically, qualified repair and maintenance (for example) are required. About what features s -tronic and the reviews of the owners of the car with it, we will talk more.

Concept and design preselective boxes

Any transmissions are characterized by certain strengths and weaknesses. The main minus of the classic "automaton" is the opening of power during the transition from one transmission to another. To eliminate this deficiency, auto industry representatives are developing upgraded automatic transmission, where transmission change is possible without this opening (rupture). This led to the appearance of preselective boxes.

Their idea is quite simple. As a basis for creating the work of the manual transmission with a pair of shafts. In fact, this box has two clips, allowing to exclude the power break during transition between the transmissions. This decision not only helped to increase dynamic characteristics, reduce gasoline consumption and / or diesel engine, but also improve the safety of the car during overtaking and the implementation of other maneuvers at speed.

Today, 7-speed preselective robotic boxes are put on AUDI brand cars, which are called S -tronic. This unit has proven itself in the market, is considered reliable, technological and such that contributes to increased comfort when driving a car.

Compact sizes

One of the strengths of preselective 7-speed boxes created by the Volkswagen concern are relatively small overall dimensions of the aggregate. Due to this feature, this robotic checkpoint can be applied on compact vehicles that differ in limited subcarrane space. That is why S -tronic is in demand today and in various small car cars, where the installation of a full six or seven-step "automaton" is extremely difficult.

Thus, in the urban compact car of the Audi brand, thanks to the development of a preselative unit, it became possible to use multistage automatic transmission or RCPP, which contributes to the implementation of the dynamic potential of the engine, and the efficiency of fuel consumption, and increased safety.

How does s -tronic work?

Constructively, this development of the Volkswagen concern is closer to the mechanical CAT, which are equipped with a robot - an automatic device switching steps. In vehicles with S -tronic, it is assumed to use stealless "petals" (switches for manual shift), although it is quite effectively coping with the tasks and automatic mode. The process and automatic, and manual switching takes the fraction of a second, and the power loss does not occur, as two clutches are involved.

The 7-speed S -Tronic box for Audi is characterized by the presence of a computer control system that tracks all transmission operation parameters. If any problem occurs, for example, fails, the computer will display a warning to the dashboard. Thanks to this feature, the operation of the car is not only simplified and the driver's comfort increases, but it also appears to respond to breakage and reduce the cost of maintenance and / or repair of the aggregate.

With all the advantages of this box "AUTOMAT" for Audi cars, the minuses of the unit also have, we should consider the owners of a car with such a transmission. First of all, this automatic transmission has a complicated design, which allows you to achieve a smooth transition between speeds without jerks and gaps in power.

An increase in the number of rolling parts leads to an increase in the risk of breakage even, despite the fact that all elements are made of durable and reliable materials.

The second important feature of the 7-speed box is an urgent need for timely qualified service. So, first of all, the unit requires a regular replacement of oil, which is worth performing every 40-50 thousand mg of mileage.

Another specific feature of this box is constructive differences from classic "automata". Because of this, a number of specialists and masters of car services are not taken for working with this unit, which should also be taken into account by potential buyers of auto audi with this automatic transmission.
