What is DSG 6. Direct SHIFT Gearbox (DSG) direct shift box. What is common between automatic transmission and dsg

The first cars with DSG robots appeared in Russia in the early 2000s. During this period, the aggregates suffered a variety of conversion operations. Let us consider in more detail how the latest modifications of the two main representatives of the DSG family have been shown, which are not considered the most reliable.

No alcohol law

Most of all called the seven-step robot-robot DSG (DQ200) with double dry clutch. The reason for complaints lies in constructive features such robots. This is a simplified and reduced version of the "wet" type boxes - designed for a significantly smaller torque. From here I. typical shortcomings: More coarse, uncomfortable switching and fast wear of clutch disks.

The seven-step robot DSG has two principal modifications. The early received the 0am index, and later and to this day wears the designation of 0CV, despite numerous subsequent innovations. Large-scale modernization of 2011 touched on all components of the robot: adhesion, mechatronics (control unit) and mechanical part (classical elements mechanical box). Life has shown that all updates went good. DQ200 has become more reliable, but the motorists still looked at it with fear - the number of breakdowns was very significant.

The second serious modernization of DSG7 formally passed in early 2014, although the updated unit appeared back in 2013, for example, on. The manufacturer was so confident in the success of upgrading, which again changed the box. In 2012, due to the mass complaints of the owners, it was extended up to five years or 150,000 km of run. And for cars released after January 1, 2014, it was again reduced by equating the deadlines to the general warranty on the concern cars.

According to representatives groups Volkswagen.After updating the box, the number of claims due to its failures decreased several times. This is confirmed by the employees of the dealership service station. Less rainbow, but still very positive, is the statistics of informal service centers. The reliability of DSG7 as a whole and the quality of its work has increased significantly. However, some repair operations are still demanding.

Major malfunctions DQ200: clutch wear, gear shift bearings and mechatronics death. The clutch node is already upgraded in the sixth or seventh time, and it brings fruits: its average resource is selected to 100,000 km. And Mechatronics still behaves unpredictable: may die at any time. Dealers are obliged to change it assembly on a new one (this is the so-called aggregate repair), but the advanced non-fakes have long been repaired and successfully repair the node. Moreover, according to them, as a rule, the reason for breakdowns is a factory marriage. This explains the fact that they usually refuse mechatronics from certain parties. The nodes suffer both the hydraulic part and electronic. The faulty fees are perepaled, and in the hydraulic part they change the dead valves and, if possible, restore their block. There is a market on the market full set Required spare parts.

DSG7 most often wear the bearings of the forks of the sixth and rear gear. The manufacturer has released even their repair kit. Profile unofficial hundreds are taken for such work, but dealers for malfunctions of the mechanical part prefer to change the box assembly. It is connected with both the manufacturer's policy, according to which the repair implies the full discerning of the robot, often recognize in economically inappropriate, and with the periodic absence of specific parts for ordering through the dealer network. And competent non-states always have access to spare parts, the necessary equipment and special tools.

The manufacturer does not regulate in the mechanical part of the DQ200, it is designed for the entire service life of the box. However, it is desirable to replace the oil about 50,000 km of run - it will extend the bearing resource on the gear shift forks.

DSG7 reliability also increased new versions. software. Fresh firmware has a different gear and clutch control algorithm. In particular, the new program will not give dramatically from the traffic light. No matter how much the driver nor the gas pedal when starting from the place, the car will fly only after a complete closure of the clutch, which is shown smoothly and with a certain delay.

And further. The DQ200 box is calculated for the maximum torque of 250 N · m. Any attempts to make a motor chip tuning will lead to a significant reduction in the robot resource. We will have to change the clutch times two more often, and even to upset on full repair aggregate. Nevochalov, it is estimated at about 100,000 rubles.

Wet

The six-speed DSG with wet clutches (DQ250) has appeared much earlier than the "dry" box. The main modernization of DQ250 was held in 2009, and after that it delivers - it is considered to be in dealer centers and the Moscow representative office of the Volkswagen concern. Neo fakes do not agree with this and assure that in the early years after modernization, the problems with mechatronics were - similar to the fact that the DSG7 appeared, but later the situation was recovered.

In 2013, the manufacturer partially changed the box of the box so that it would not interfere with the anticipation of the suspension lever bolt, and also updated the internal and external filters. In addition, the new software versions and modification of the wet clutch are periodically published - the node is upgraded for the fourth time.

Robots with wet clutch have many advantages compared to "dry" boxes. However, DSG6 has serious shortcomings. For example, the oil circuit combines the clutch, the mechatronics and the mechanical part of the box - and often the repair DQ250 implies the replacement of a heap of elements. It happens, the clutch wear products fall into the mechatronics and it begins to fool, quickly admiring the clutch and elements of the mechanical part of the box. Sometimes conspiracy participants change in places in any order. Hence the requirement of the plant to change the oil in the box every 60,000 km. But it is better to be reinforced and reduce this interval to 40,000 km.

The second drawback of DQ250 is known for classic machine guns. Cars with DSG6 are contraindicated long-term slip of the wheels - overheating oil leads to deposits.

Most often, the problems with DSG6 are caused by inadequate operation - engine chip-tuning and aggressive ride. As a result, the clutch resource is reduced several times. But much more terrible that in such conditions the box strongly suffers from the mechanical part. For example, gear gear and main pair are stepping up - and wear products quickly kill the unit.

In this case, DQ250 without interference with the software perfectly feels in ring races. It is only necessary to change the oil in the middle of the season. But the passion for "flights" in the city with a ripped ride mode often turns into serious costs: Full repair of DSG6 in non-states costs about 120,000 rubles.

Head on shoulders

Per last years The manufacturer significantly improved the design of DSG robots with two clips. From the status of unreliable thin, the DQ250 box was separated, and DQ200 is pulled up to it. Concern VW conducts comprehensive work on errors, constantly analyzing the statistics of the operation of cars in russian conditions. Confirmation of this is excellent indicators of the reliability of seven-step DSG with wet clutches (DQ500 index), which from 2014 is installed on some concern machines intended for our market.

Output? Candid problems with German robots are due mainly inadequate operation. Servicemen of all stripes advise to think their heads, do not get involved in aggressive ride and do not interfere with DSG boxes. So it is so, but the Germans conducted work on mistakes at the expense of buyers of their cars.

Engineering thought does not stand still, and the developers of automotive equipment seek to offer their customers all new solutions that should facilitate the life of the motorist. One of these inventions has become DSG Transmission. Translated from the original language, the name decryption sounds like this: to the "direct inclusion of transmissions".

DSG Box - Combination Result mechanical gearbox And Boxes -Avtomat. The principle of operation of this type of checkpoint is the presence of robotic equipment that automatically switches the transmission after the driver makes the lever movement by choosing the transmission.

DSG automatic transmission, currently occurs in two versions: six and seven-seven. The six-speed DSG enrolled in production in 2003 and made it possible to reduce the time of overclocking cars by combining this function with fuel savings. DSG (seven) is a seven-step version of automatic transmission, which is becoming increasingly distributed and is often used on sports carsFor which fast acceleration and smooth speed switching are important.

Let's figure out what the DSG box is and what the differences of its work compared to the familiar automatic and mechanical gearbox.

Description of the principle of operation of the CAT

This automatic transmission has two clips, providing no power loss when switching. This is because at the time of switching one of the clips is turned off and immediately turns on the second, which before that was in complete readiness. Thus, it can be noted that the DSG system includes, in essence, two equal boxes, one of which is responsible for even transmissions, and the second is for odd.

While moving both, they are in working condition, but at each moment the adhesion of only one box is closed, and when switching it swallows, clutch clutch to another. The box is considered robotic, because gear shutdown the electronic unit - Mechatronics. It is electronic devicewhose work consists in timely closure / opening of clutches. The robot tracks information that comes from all sensors: controlling the frequency of rotation that follows the heating and the amount of oil markers in which position are plugs on the transmission.

In general, it is believed that the DSG gearbox is a functional more perfect MCP. Technically, it is, and the main improvement is just a robot that makes switching rapid and uninterrupted. In models released from 2015 to 2017, Mechatronik received additional features to help avoid breakdowns and increase the service life.

How DSG 7 works and what is the difference from previous samples

The main difference between seven- and six-speed boxes is their principle of operation. If the "wet" principle is used in DSG (six), in which the mechanical parts are immersed in the oil are constantly cooled, then in DSG 7, dry clutch is not overwhelmed due to the reduced torque. In this case, oil saves occurs, as it is used only for lubricating disks.

Thanks to these differences, two types of robotic boxes have several different applications. Boxes with wet principle of work more often can be found on more powerful car, for example, such as Skoda Octavia, and on the machine for which the torque does not matter much, the dry box is often installed.

Advantages of DSG PPC

TO positive sides The work of the DSG box can be attributed as follows:

• maximum quick gear shift;
• fuel economy due to the lack of power loss when switching from one transmission to another;
• increasing the speed of overclocking, the impossible in the car on which the standard mechanical or automatic box is installed;
• the possibility of manual transmission switching.

All these positive features made DSG boxes optimally suitable for the development of the modern automotive industry. For example, Skoda has been using these transmissions for different models of Skoda Octavia for several years. So, by the end of 2014, the Skoda managed to release more than half a million DSG boxes.

But, despite the recognition among manufacturers, car enthusiasts continue to argue whether a robotic gearbox DSG 6 or its seventh version is better than the usual automatic transmission.

Disadvantages of using DSG in the car

Among those who have already bought a car with a DSG 7 gearbox, are not only its fans, but also people who have time to test her in action and found some disadvantages of such innovation:

• the complexity of the design of the new PPC increases the cost of the car on which it is installed;
• there are often temperatures that reduce the life of the transmission;
• despite the large number of services, some serious breakdowns are simply impossible to eliminate without replacing the gearbox completely. The same applies to cases when a robot came out - it is simply not subject to repair.

In addition, many motorists argue that the resource of this checkpoint is much less than the manufacturer.

Summarizing all of the above, I want to recall the motorists about the need for a thorough check of all systems when buying. Deciding to acquire a modern car, you need to think about what reserves will require its service.

I decided to talk about one of the most popular automatic boxes DSG, which is equipped with a large number of cars mainly German production. You will learn about the principles of DSG, as well as its strong and weaknesses. I wonder then went!

So, let's start with what DSG is? This abbreviation is decrypted as: " DIREKT SCHALT GETRIEBE. "And translated from the German" Direct Shift Box "or" Direct Turning Box ". Quite often, next to the DSG, you can meet the prefix" Related ", which in the" Human Language "means that the box constantly prepares the following transmission for Switch.

I invented the DSG box French Engineer-inventor Adolf Kegresce in the 30s of the last century. At that time, Adolf collaborated with which one actually was proposed to integrate nEW CPP With two clutches and hydromechanical control. Citroen Traction Avant was selected as the experimental. However, the mass box did not become due to its complexity and high cost.

DSG: How does it work?

The main difference of preselative gearbox from classical analogues is to use two clips, as well as in the shift speed. On mechanical, as well as robotic gearboxes to switch the transmission disk disconnected from, after a driver, or a robot (in the case of robotic gearbox) Selects the necessary gear. After that returns the clutch disc to the place. All these manipulations are somehow connected with the loss of dynamics, since during them from the motor is not transmitted to the box.

As you already guessed, DSG provides switching without loss of dynamics and power through the use of two coaxially arranged shafts. The first shaft is hollow, and the second shaft is located inside it. The motor is connected to each of the shafts by means of a separate multi-disc clutch of external and internal, respectively. On the external (primary) shaft, the non-gear gears (2, 4, 6) are located, on the inner (secondary) - odd (1, 3, 5, as well as reverse).

At the beginning of the move, when the car rows from the place, the disk with odd gears is pressed against the rotating flywheel, while the secondary disk on which even transmissions are located are in an open state. When the car begins to accelerate, the special computing unit "DSG" gives the command to prepare the second speed, so that during its inclusion instantly turn off the disk disk and simultaneously connect the disk with even transmissions. Such "reheated" control of gears and shafts allows you to switch in seconds without loss of torque.

In mass production, a robotic DSG 6 box was launched in 2003 company Volkswagen.. Due to the fact that in this box was located in the oil bath, they began to call it "wet." Unlike the "dry" analogue, in a wet clutch boxes, a part of the engine power is spent on the oil, which prevents the rotation, and also increases fuel consumption. Five years later, the Germans presented a modified seven-step DSG 7, in which "dry" clutch was already used.

Pros DSG.

• Thanks to the "smart" speed switching, as well as correctly configured inclusion modes, the DSG box allows (+ -10%).
• Excellent dynamics due to instant gear shift, to increase the transfer, "DSG" spending some 8 ms.
• DSG allows you to use it in manual mode, that is, something like.
• The weight of such a box is 20% less compared to the equipped hydraulicone.

Disadvantages of DSG.

• Price. Cars with DSG are more expensive compared to similar models without this box.
• Replacing the oil in the "DSG" box is expensive, since it is necessary for it special oil in the amount of 6.5 liters. In addition, the replacement itself is regulated after every 60 thousand km. Run.
• Expensive repair. Consider a faulty DSG will be expensive, moreover, not all the hundred are taken for such work. The reason is the complexity of the construction and the unprofitability of the repairs itself, since he takes a lot of time and effort.
• Delays in shifting gear. Despite the fact that above I talked about instantaneous switching, are observed on DSG and delays. This is happening at the moment when the driver presses sharply on gas to accelerate faster. At this point, there is a delay, "Tupun" for the reason that the computing unit has prepared a higher transmission, but at the last moment the driver pressed sharply on gas and in order to give a sharp increase in power, it is necessary not to increase, but to lower the transmission. As a result, a slight delay occurs, after which a sharp jerk and acceleration.

Recasive "DSG Robot" is installed on a large number of car brands that belong to German volkswagen concernAmong them you can highlight: ŠKODA, Audi, Seat, and of course the car itself Volkswagen.

Myths about DSG.

Among the motorists there are various rumors about this box, some she really likes, while others are afraid of her "like the features of Ladan" and do not buy this or that model of the car only because it is completed with a resettlement Robot "DSG". I will not delve into details and argue about who is right, and who is not, I will say only that the earlier modifications of this box really could deliver a lot of trouble, especially on secondary market. However, after serious refinement of the sixth generation DSG.This box has stopped associated with unreliability and expensive repair. The fact is that Volkswagen himself went to meet customers, and to prove the reliability of their boxes expanded on them a guarantee.

Basic malfunctions "DSG".

• One of the most common faults are shocks during the shift of the gear, in which the car pulls forward. It happens because of the too sharp closure of the discs, because of which the car is twitching.
• The second most popular problem is the vibration when starting, as well as foreign sounds when switching gear.

Also found on DSG robots: shocks when switching (box is kicking); The box is buzzing while driving; Some transmissions are not included; Strong vibration when starting.

As a rule, the incorrect work of seven-step Dsg is in the "dry" clutch. Permanent loads lead to rapid wear of working parts. The main wear occurs during long "hard" when the car is slowly moving. To extend the "Life" DSG, it is necessary to avoid frequent combinations of "gas-brake" if possible.

Finally...

In general, as any other mechanism, subject to the rules of operation, the robotic DSG box will not deliver any trouble. A double-clutch box has a lot of advantages over ordinary automatic transmission, which have already rated millions of happy car owners.

What is DSG? With the German abbreviation DSG decrypts as a "direct inclusion box" (DIREKT SCHALT GETRIEBE). Often it is called "preselative", that is, who can keep ready-made transmissions for the next switching.

The idea of \u200b\u200bcreating such a gearbox belongs to the French inventor Adolf Kegresce. In the 30s of the last century, the automotive engineer collaborated with Citroen. He proposed to put an aggregate with two clutches and hydromechanical control on the front-wheel drive Citroen Traction Avant. New Transmission Not received mass use due to complex design.

The technical consultant Volkswagen Favorite Hoff Maxim Ponomarenko told about the advantages and features of the box.

Principle of operation dsg.

The fundamental difference between the preselative ACP from others - in two clutches, promptly switching transmissions. In "Mechanics" or robotic box To change the transmission, the clutch disc is disconnected from the flywheel, the driver or a robotic computer selects the desired "speed", and after that the disc rises in place. During this time, the torque is not transmitted to the box and the car loses in the dynamics.

The DSG system allows you to get rid of power failures. At the heart of the box work of two shafts located coaxially: the first is hollow, and the second is inside it. The engine is connected to each of them through its, separate multi-disc clutch - also external and internal. On the primary, that is, the outer shaft is fixed by the sixte gears (2-, 4-, 6th), on the internal - odd - 1-, 3-, 5th and transmission of the reverse.

When the car starts, a disk with an odd pavement is pressed to the rotating flywheel, and the disc with even "speeds" will open. During acceleration, the computing box of the box gives the command to prepare the second transmission, so that at the time of its inclusion, disconnect the disk of the odd row and instantly put into operation a disc into operation. Customized switching control allows not to lose torque.

The Robotic Gearbox DSG 6 stood on the Volkswagen conveyor in 2003. Double clutch It worked on her oil bath, having received the name "wet". Oil in such a box takes part of the power, increasing fuel consumption. In 2008, German autocontracean presented the seven-step DSG 7 with a "dry" clutch.

Advantages of DSG.

• DSG box due to the optimal mode of inclusion of the desired "speeds" allows to reduce fuel consumption. Cars with it consume about 10% less fuel than cars on which a regular gearbox.
• A distinctive feature of all similar transmissions is a dynamic acceleration. To switch the transfer up the box, you need only 8 ms, it does not have the effect of rubber thrust as on the hydromechanical ACP.
• You can ride on DSG in manual mode, that is, switching transfer manually.
• Such an ACP is 20% easier than similar hydromechanical transmission.

Disadvantages of DSG.

• The cost of the ACP affects the price of a car, significantly increasing it.
• Cheap oil replacement (on a six-speed box) every 60 thousand kilometers. Full volume - 6.5 liters.

Preselerative box is installed on different models and stamps, combined by Volkswagen: Audi TT (A1, A3, A4, S4, A5, A7, A3, Q5, R8), SEAT Ibiza (León, Altea), Škoda Octavia (Superb, Yeti), Volkswagen Polo (Golf, Jetta, Touran, New Beetle, Passat, Passat CC, Sharan, Scirocco, Caddy).

Extended Warranty on DSG

Among the many car owners, dubious fame of the box with two clutches was entrusted. The name of the DSG itself turned into a symbol of an unreliable design with costly repairs. In fact, Volkswagen has long taken to control the situation under control. An important step towards quality control is a large-scale service action.

The concern gives an extended warranty for seven-step boxes issued before January 1, 2014. According to representatives of the autoconcert, the designated period corresponds to the appearance on the conveyor of the modernized transmission without typical problems last generation. Special conditions for maintenance are limited to 150 thousand mileage or 5 years of the mechanism. The service share includes replacement synthetic oil Mineral - less aggressive in relation to electronic components. This updates the firmware of the ACP control unit. Detected faults are eliminated free - it concerns repair, replace individual elements or transmission assembly.

In any case, the DSG abbreviation should not be afraid: with the proper maintenance, it will not submit, and by the number of advantages, the "smart robot" wins in the classical automatic transmission. And another DSG box will require less money for repairs in comparison with the usual "automatic".

What faults are characteristic of DSG?

SAMI frequent problem - Shocks when changing transmission accompanying movement. Clutch discs are too sharply closed and pulls the car. The second known drawback is the vibration at start, clang, grinds and other extraneous noises during the change of speeds.

The main reason for the incorrect work of the seven-step transmission is its "dry" clutch. It is quickly wearing because heavy Conditions operation in tight urban traffic, with coughes at low speed. Therefore, the question "How to exploit DSG?" There is one obvious answer - avoid the "gas-brake" regime, because the main enemy of the robot is a traffic jam.

Among other problems: wear of the sleeves of the shafts, the plugs of the clutch, disturbed by solenoids, dirt on sensors and oil in antifreeze.

How to determine the malfunction of DSG when buying a car with mileage?

• Separate programs are not included - the box "jumps" them.
• The gear shift is accompanied by shocks - the box "kicks".
• When driving heard a buzz.
• The machine vibrates at the start.
• Inspection on the lift shows that oil leaks out of the box.

If there is a suspicion of incorrect box work, you should order an additional check, or postpone this option.

Find out what this is a DSG gearbox, its advantages and disadvantages, a scheme and principle of operation. What cars installed DSGs. Description of the ECT system. Video.

DSG (the full name "Direct Shift Gearbox" - a direct switching transmission) is a mechanical 6 or 7-speed box. She has automatic drive to turn on gears and two clips. The peculiarity of such a box is that its connection with the motor occurs through two clutches. They are located coaxially.

DSG gearbox operation principle

In this case, through one clutch, such programs are functioning: rear and odd. Through another clutch - you work. Thanks to such a device between the steps, a smooth transition is performed. This is similar to the synchronous triggering of the frictional range of transmissions operating in mechanical "automata".

While on the first program, there is still overclocking, the gear of the second stage is already in engagement, despite the fact that so far is rotated. On the computer is determined by the moment of switching. At this point, the DSG hydraulic rods are made simultaneous release of the first clutch and the complete closure of the second. The transition of torque that comes from the engine, from the first transmission to the second one. The process continues in the same way until the last sixth stage. After that, the opposite happens. When the sixth gear is turned on simultaneously with it, the gear of the fifth is rotated.

Video about the principle of work:

Advantages of DSG.

The advantages of this box are also in reducing overclocking time, and in fuel economy. And this is important today. It is even more important that when operating the DSG switching, the illusion is not commemorated and the illusion that riding is constantly on one transmission. In the cabin there are only two pedals - brake, gas. This is enough. Transmission selector is such as automatic gearbox. If you suddenly do not like it, it is always possible to use manual mode, in which the box lever is translated up or down.

Disadvantages of DSG (its problems):

• The cost of the car with this PP system is significantly increasing due to the technical complexity of the equipment itself.
• According to the reviews of some car owners, it can be noted when setting the speed and when switching gear, small car jerks.
• There are small delays in a sharp acceleration - the PPC does not have time to immediately jump through the transmission. For example: you eat on a 4-time transmission and suddenly decided to dramatically dial the speed, respectively, the box should be pulled out through the fifth on the sixth stage, but it is already configured to a smooth transition to the 5th speed, as a result, a delay occurs.
• Control blocks (mechatronics) are quickly wearing and require premature repairs.

What is "ect"?

IN recent models Automatic gearbox there is an innovation. They are installed on them (an electronic system, with which you can control the switching gear). This system It makes it possible to smoothly switch the transfer along with taking into account the speed of the machine, the engine temperature and the opening values \u200b\u200bof the throttle valve.

Due to this, the life of the engine, as well as the transmission increases significantly. Depending on the taste of the car owner, you can choose different switching schemes: sports, economical or winter. For example, when using sports mode, the inclusion of each transmission occurs a little later. As a result, it is possible to develop high power of the engine and its faster acceleration. It is convenient when you need to join the stream of machines, which is moving fast. However, the fuel consumption is also rising. therefore final choice Always remains for the driver.
