What is a tronic box. What is the difference between s-tronic from DSG? Adaptation of the high-speed box

Today, large automakers are increasingly equipping new models of their auto preselective checkpits.
Gradually, the "robot" with two clutches becomes the usual attribute of a premium configuration.

What is the difference between the S-Tronic from the DSG - marketing stroke or different aggregates?

However, Volkswagen and Audi are allocated from the general list - they first went on this path, starting the massive application of preselers in the early 2000s.
The transmission, installed on the Volkswagen machines, received the name DSG (abbreviation from Direct Shift Gearbox).

The invention Audi was represented by the world called S-Tronic.

As you know, both of these companies are divisions of the concern VAG. Given this "kinship" and the simultaneous output of the RCPP, it can be assumed that the developments were conducted together. Confirms this guess and the fact that DSG and S-Tronic does not have obvious structural or technological differences.

Moreover, there is an opinion that the s-bronix is \u200b\u200brebranding DSG.

However, everything is not so obvious. The snag lies in the layout of the motor, which, in the case of Audi, rather non-standard.
A huge part of cars from the Audi model range is distinguished by the longitudinal location of the engine.
As for most passenger cars, including the battle of Volkswagen - there the motor is placed transversely.
All generations and modifications of DSG are also calculated on the transverse layout.
At this stage, it becomes clear what the S-Tronic differs from the DSG.

With Iron confidence you can say that certain changes and improvements of Audi accurately had to make.

Unique modifications of S-Tronic are installed on all all-wheel drive and some front-wheel drive models.
You can distinguish such aggregates by factory label - DL382 and DL501. For service notation, indices are commonly used: 0B5, 0CK, 0CL, 0CJ.

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.

As you know, since 2002, DSG boxes are installed on Volkswagen, Skoda and Seat cars.
At the same time, the Audi began to serve S-Tronic transmission serially.
At the same time, all listed companies enter the Unified Concern - Volkswagen Group.
It is quite expected, such a "coincidence" has become a reason for numerous guesses and disputes. We will try to clarify the situation.

Considering the relationship of companies, it really does not make sense to look for serious differences between s-bronide and DSG.

Moreover, many RCP models are full twins.
This list includes: DSG-7 (DQ-200), DSG-6 (DQ-20) and DSG-7 (DQ-500).
However, there is a brand with four rings and its own developments.
We are talking about transmissions that are designed for the longitudinal location of the engine.

Because of the transverse layout, until 2008, the existing versions of DSG covered not the entire lineup.
To solve this problem, Audi company has released a box version of DL-501.
Its characteristics are coincided with DQ-500, and the design is adapted to the longitudinal placement of the motor.
DL-501 is used only on high-wheel drive AUDI all-wheel drive machines.

The second unique development was DL-382. Having 400 nm of the maximum torque, the box is available in two versions: for front-wheel drive (F) and all-wheel drive (q) auto.

So the question what is the difference between s-tronic from DSGYou can not answer unequivocally.

In general, these are identical aggregates issued under different trade names.
However, some Audi models are still equipped with exclusive boxes that have no analogues in the DSG line.
You can distinguish these PPCs by factory indexes: 0B5, 0CK, 0CL, 0CJ.

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.

Modern diagnostic equipment used in service centers also contributes to rapid definition of malfunction and its elimination, if the problem warning is generally common (there is a warning from a transmission computer, but without concretizing the reasons).

Another specific feature of this preselective box is to ensure greater maneuverability when turning. In maneuvers to the right, the cooking increases due to the compression of friction packets, and when turning to the left, a hydraulic engine is locked, which gives the right wheel an increased torque.

Reliability level S -tronic

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. To do this, there are additional clutches and shafts. 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. Ignoring this recommendation and the desire to save on service as a result will turn into additional costs - probably it will be necessary or fails. S -tronic box is demanding and to the type of oil - only original brands are recommended.

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.

Volkswagen and Audi are rightly considered pioneers in the serial use of robotic gearbox with dual clutch.
Actively install preselective boxes for their cars, manufacturers began in 2003.
Since then, the Volkswagen models are equipped with a transmission called DSG, and the development of AUDI received the name S-Tronic.

Here it looks like now the classic DSG box 7

First of all, it will be fair to note that both companies are the divisions of the concern VAG.
Given this fact, it is almost useless to look for any serious constructive or technological differences in the aggregates.
Moreover, comparing the existing modifications of DSG, it can be noted that most of the versions of C-Tronic are their complete analog.

However, there is still exceptions!

We must not forget that many modern Audi models have a longitudinal location of the motor,
while all versions of DSG are equipped with transversely installed power units.

And this is an option for the RCPP S-Tronic for Audi (Standard)

And Option C-Tronic For Audi A7 Sportsback is also equipped with a wet clutch knot

Thus, under the hood at the all-wheel drive and part of the front-wheel drive models from AUDI, there are unique modifications of S-Tronic,
not having "twins" in the DSG lineup.
Recovered PPCs have the factory labeling DL382 and DL501, and are indicated by the following indices: 0B5, 0CK, 0CL, 0CJ.
