How the DSG box works. DSG - What is it? Features and problems of DSG gearbox. Clutch in DSG gearbox

The most famous representative of the new generation automatic gearbox Is a DSG box. In particular, its installation on the Machines of the German production Volkswagen made these vehicles popular among consumers. If you do not know what is on Volkswagen - you can read reviews about these boxes on our website. After reading the material, you will learn the advantages of these gearboxes and the nuances that every car owner may face.

Main characteristics

On the passenger vehicles of the PPP DSG "swinging" from "Formula 1" and first they began to be installed on german cars Volkswagen. Initially, a robotic velocity box with two clutches was a conventional improved "mechanics". But in this mechanical box there were two primary and two secondary shafts, and each of them connected with the engine through a personal multi-disc clutch.

What is the principle of operation of such PPC? When the first coupling speed is turned on, which performs the role of the synchronizer in the manual transmission, performs the speed of the speed gear on the slave pulley. At this time, the adhesion closes, and the torque is transmitted through the inner pulley on the wheels. Including speed, the DSG unit immediately blocks the second steps gears using electronics.

Video from Alexander Kozakova "Heated VW Passat 2.0"

In this video, the process of heating the VW Passat car with an equipped DSG 6 at a temperature of 18.5 degrees Celsius is below zero.

Switching to the second speed, the disks of the first clutch as directed on-board computer Overweight and closure. At this time, the torque begins to be transmitted through the primary pulley and two gears of the second speed. Thus, the vehicle is accelerated. When dumping the DSG box speed operates in reverse order.

All DSG operations manages the electronic unitwhich determines the procedure for all elements transmission system Based on the position of the gas pedal. It should also be noted that using the DSG box with the so-called wet clutch Ensures the functioning of discs in the oil tank.

There may be two DSG options: DSG 7 and DSG 6 with "dry" and "wet" clutch, respectively. Both transactions are used in parallel. DSG 6 is a stronger transmission option, because it can work with a large torque. Therefore, such gearbox are installed on more powerful vehicles. As for DSG 7, less powerful cars are equipped with such boxes.

For the first time DSG 6 appeared in 2003 and she worked on the "wet" clutch, i.e. In the oil tank. The main disadvantage of such a box is the loss of power due to oil. Therefore, five years later, the German car concern Volkswagen. Presented to consumers a new variant of the checkpoint - DSG 7, in which the dry clutch was used.

Advantages of vehicles with equipped DSG:

• the switching rate of one transmission is about 8 ms, which allows to provide a dynamic acceleration of the car;
• depending on the driver's preference, you can automatically monitor switching or yourself;
• the efficiency of gasoline use increases (on average by 10%).

As for the shortcomings, it is immediately worth noting that they are not so much and, as a rule, they appear far from all Volkswagen car owners. In general, it all depends exclusively from vehicleTherefore, it is impossible to clearly allocate certain symptoms of "diseases". However, these minor flaws will not be able to exceed the advantages, in particular, fuel economy and smooth speed switching. As for the working resource of the CAT, it is high enough, that is why some automakers increase the guarantee on DSG to 7-8 years.

Reviews

We invite you to familiarize yourself with the reviews of car owners working on the DSG gearbox.

In general, it can be said that automatic box dSG transmissions It is a reliable unit, which depends on the correctness of operation. In practice, cars with such gearbox confidently and dynamically behave on the road: not only in traffic jams or with a dense traffic flow, but also when making maneuvers on the track.

Judging by the reviews vOLKSWAGEN OwnersThe most common diseases on these cars are a breakdown of mechatronics and clutch. According to experts, they arise as a result properly operation boxes. In particular, we are talking about transmission fluidpoured in DSG: it should be original. Also important is the moment of warming the box in winter time year: to increase the service life, it is desirable not to touch sharply from the place at the beginning of the movement. Of course, for some it will be difficult to refrain from fast driving, because the "automatic" allows, but it is better to do it when the car warmed up to the desired temperature.

Video "All about the gearbox DSG 7"

Looking at this video, you will learn what a robotic gearbox DSG-7 and which principle of its work.

Robotic boxes broke into AvtoMir as rapidly as they are completely automatic. For the first time B. mass production And the introduction for buyers these boxes launched the Volkswagen concern. This article will tell you that the DSG box is, the principles of its work, distinguishing with the machine, pluses and minuses, as well as the fact that car manufacturers say about it.

What is a DSG box?

DSG is a second-generation robot gearbox, which switches the speed with two clips and electronics, with the driver's participation. To date, it is considered the best gearbox and most reliable. It switches the transmissions, while not breaking the power and has better dynamic qualities. Also, DSG saves fuel, because the engine does not work well.

DSG is six or seven steps. The first is installed on more powerful carsSince it is more torque. The robot for seven steps is installed on less powerful cars, as well as on some trucks and buses.

Short story

For the first time, the DSG box was developed by Borg Warner. They wanted to create an ideal gearbox that would combine all the qualities of the manual transmission, automaton and the variator and did not have flaws. The disadvantages of mechanics are known to everyone, the automaton is reducing the power, and the variator has a narrow range of work. The robot had to absorb all these shortcomings, and plus the cost of maintenance and repair.

But everything went wrong, as I wanted. It turned out that the six-speed box is not suitable for cars with low power. Then there was an additional box for seven steps, which was suitable for such cars. But the excuse was not confirmed because it was dry.

Year of work, testing, refinement and new DSG was introduced on some Volkswagen cars. Of course, it was not without incident, and the first batch was with defects. But the plant quickly corrected and now the robot is widely applied on many cars.

Principle of operation

The genius of the DSG box is that it combines two boxes in one case. It is equipped with two shafts, on one - even transmissions, on the second - odd. Two clutches, for each shaft, allow you to most effectively switch transmissions without loss of power and short braking, as in the machine.

The clutch DSG is six steps - the robot "wet" type (constantly in oil). This is done in order to cool the discs and constantly attended the lubricant. This feature significantly increased the RESO resource and it is about 300 thousand km. With gentle use, you can stretch to 450,000 km.

DSG-7, or seven-step robot box, equipped with dry clutch. This is done to reduce maintenance and maintenance costs, but the wear has increased and the resource has decreased.

What is the difference between the robot from the automatic transmission?

When buying a car, any motorist thinks, what is the best box to take? Repeatedly it puts a man in a dead end. So what is the difference between the robot and the machine?

The first difference is constructive. The robot is made so that the car does not lose power, and the gear shift does not brake the dynamics. The second is a technical difference: this is what the robot in its structure is mechanics and requires
Participation of the driver in shifting.

Other differences of the machine and robot:

• the robot is easier than the machine, because by nature a robotic box is mechanics;
• at the robot, the presence of electronics, which manages the switching;
• fuel economy by a robot;
• ability to change the settings of the robot for of different types and travel manners;
• manufacturability of the design under modernity;
• high reliability and quality robot.

Pros and Cons DSG

The advantages are:

• saving fuel (only compared to the machine, on the saving variator more);
• instant transmission change;
• no power loss;
• high resource;
• manual control.

Cons DSG:

• the great cost of repair;
• expensive cost of oil replacement (for DSG-6);
• does not tolerate the aggressive driving style;
• the cost of the car is more expensive.

Producers offer in robotic boxes

The Volkswagen manufacturer promises the refinement of robotic boxes, as they are not yet thoroughly. The main problem, which automakers in front of them, is to reduce the cost of maintenance and repair. Leaving
Benefits You need to make repairs and then cheaper, since not every ordinary consumer can afford to serve the car with such a cost of spare parts and materials.

According to many experts, these boxes are the future, although another 40 years ago they were considered not promising and practically deceased options. Now they recruit supporters and those who would like to have a car with a box
DSG, but can not afford it. But manufacturers promise to do everything in order to make the most available to an ordinary consumer.

Output

Examined robotic gearbox DSG can be concluded that today it is the most ideal box that combines all the advantages of mechanics and a machine gun, while not expensive in maintenance 😉 like a variator. It has a sufficient number of advantages that modern drivers are needed.

DSG is decrypted as Direkt Schalt GetRieb, in a literal translation from the German - "Direct Transmission Box". This is one of the many types of preselective robotic boxes with two clips.

As you know, the "robot" is a manual box, but with automated control. When you need to switch the transfer, the computer gives the command to actuators that disconnect the slave clutch disc from the master, thereby disconnecting the engine and the box, move the shafts with gears, and then connect the disks back, renewing the process of transferring the moment.

I must say that with this operation, the computer does not always cope quickly - often it needs even more than the driver. About the dynamic ride and even more so sport with a conventional robotic box can not be speech.

Quite another thing - box with double clutch! Principal scheme Such a gearbox came up with the French engineer Adolf Kegres. Before the First World War, by the way, he worked in the personal garage of Nicholas II and came up with a cacalyant-wheeled propulsion for the royal "Pakcarde", but this is a completely different story. In the late 30s, when Kegrax described the principle of operation of double clutch, the technology did not allow to make a prototype, and the design was forgotten until the beginning of the 80s. Then the progressive box was tested on Ford Fiesta, Ford Ranger. and peugeot 205, and then put on racing Audi and Porsche.

How does DSG work?

DSG - by no means the only preselection

Not all DSG is equally useful.

Where can I meet DSG

What problems is DSG?

• Jerk when switching up or down - The most common drawback. It caused by the fact that dry clutch discs are closed too sharply. The effect is approximately the same if on the machine with the "mechanics" throw the clutch pedal when switching.
• Outsided sounds in work. Lamb, crosses and other noises.
• Loss of thrust on acceleration. Clutch discs do not start with each other properly, and the car stops responding to pressing the gas pedal. The situation is especially dangerous when overtaking on country tracks.

Usually everyone is used to see mechanical or automatic box Transmissions. But there is a new generation gearbox - DSG. Its structure includes both mechanics and a box of automatic. Otherwise, it is called a semi-automatic or double-grip box. This type has long been used in sports cars. In the production of ordinary cars is still considered a new technology. However, the modern motorist is just necessary to know about the gearbox DSG - what it is and what is the principle of its work.

Car Iron Developers, Borg Warner, decided to create a transmission, combining qualities, as well as the characteristics of the automatic transmission and manual transmission. They created a six-speed box, but she did not work with low power machines. Later, they came up with a seven-speed gearbox, but the grip in it was dry, and the robot quickly heated. After the year of hard work, the company decided to try its development on vOLKSWAGEN cars. The first batch of robots was released with defects, but soon all corrected. Now DSG is popular in the modern automotive world.

Box DSG7.

How is the gearbox DSG?

At the moment there are two modifications of transmission: a six-speed with "wet" clutch and seven. Each has some features or shortcomings, but about them a little later.
7-speed consists of:

1. The first output shaft.
2. Second output shaft.
3. Major transfer.
4. Primary shaft.
5. Mechatronic.
6. Oil filter.

The first cars with the DSG of the Volkswagen AG line machine. They came out from the conveyor and smoothed the world about this technology. At the factory, this day is manufactured by this checkpoint. So what is the DSG box? It is 5 shafts that are connected by gears and 2 clutches. These technology, they form a kind of mechanism that is very different from classic gearboxes. It is he who is responsible for the rapid acceleration of the car and a greater speed, as in machines with mechanics.

Internal device DSG.

Due to the fact that switching gear is very quickly, the DSG gearbox began to be introduced into sports cars, where it is very important.

What is the feature of the CAT with two clutches and mechanical transmission?

The newest PPC works very quickly and smoothly. All transmissions switches instantly - this is a trump card for racing cars, where the speed is primarily. Transmission has differences from mechanics. Let's remind the principle of work mechanical gearbox:

1. When the driver includes a clutch, the motor separation from the transmission occurs, thereby stopping the flow of the power flow to the checkpoint.
2. After moving the gear lever, the transition of the gear coupling from one gear to the other, despite the fact that they are different.
3. During this process, the speed of rotation of the coupling is gradually aligned, which leads to the inclusion of the next transmission.
4. When the adhesion pedal is released, the transmission is again connected to the motor, the torque is started, which goes into rotation of the car's wheels.

Each process is not felt physically to the driver, but if an inexperienced driver is driving, then thanks to the stop of the power flow from the motor to the transmission, the push, which feels the driver with passengers in the cabin. The principle of operation DSG includes the process of working mechanics and automatic boxes. There is no clutch pedal. there is 2 automatic clutchwhich regulate odd (first) and even (second) transmission. Speed \u200b\u200bswitches with irresistible smoothness. This contributes to the electronic control system of the transmission Mechatronic.

In DSG gears are located on different shafts. If there was a single shaft in the mechanics, then there are even and odd placed on the first and second output shaft. In this case, the inner shaft is placed in the external so that even transmissions work from external, and odd from internal.

Robotic DSG box

Opinions of experts and users

Reviews of users on the checkpoint are completely different. We offer detail to consider all the pros and cons of this gearbox. For example, those who enjoyed technology, she soul. There are a number of reasons for this:

• a smaller fuel is consumed. For the car on the DSG box, you need 10.2 liters of fuel at 100 kilometers of the way, which is even less than in the manual transmission;
• fast and smooth speed switching;
• for racing competitions, cars with a box DSG are clearly suitable, because when you turn on the transmission, the following is already ready for activation;
• robotic box can operate both automatic transmission and in mode. manual switching speeds for the convenience of users (like tiptronic);
• no speed loss and power (almost comparable to mechanics).

CPP also has a number of negative factorswho noticed real users during the use of the box. DSG can be found on the transmission negative feedbackwho even dissuade motorists from buying a car with a semi-automatic gearbox:

Now you know why the DSG criticizes in modern worldAs well as the installation of the PPC can turn into with aggressive driving on the roads of large cities.

Let's summarize the above

Semi-automatic DSG gearbox is modern technology, accommodating in one case elements of automatic and mechanical gearbox. Technology is managed electronic system Mechatronic. Used in expensive or sports cars, where you need to quickly switch the transmission. On the one hand, you should take cars with DSG, but on the other - this is not an option for a regular road ride. After all, the car may not behave unpredictable, and reliability is an indispensable factor in which every owner of his four-wheeled friend must be sure. The speed and smoothness of the switching speeds, less fuel consumption - is, of course, well, but everything will go to the background if the car will fall into an accident due to transmission in the traffic jam or any other accident will occur.

When mentioning the robotic DSG-7 transmission with dry clutch, most immediately starts talking about her unreliability. However, as practice shows, the overwhelming part of the respondents has never come across the cars equipped with this gear shift box. To understand the reliability and basic problems of DSG-7 DQ200, we decided to talk and find out opinions real ownerswho exploit VAG cars in 2017 with DSG-7 with dry clutch.

From myself we can add that in our personal order for more than 3 years Skoda Octavia. A7 equipped with a robot and 1.8 liter motor power 180 horse power. For 3 years, a car, more precisely, the Robotic Transmission Direct SHIFT GEARBOX I did not give any problems. Moreover, the car was operated mercilessly, practically in daily mode - "Slippers to Paul" with constant sharp accelerations from the traffic light. And only on mileage of 72,000 once we have experienced a small vibration, and this happened after we defended more than 3 hours in a traffic jam with a constant movement of gas brake.

Summing up, we can safely say that it has become much more reliable than the very first version that delivered a huge headache to the owners, especially it was on Volkswagen Passat. B7 first years of release. From the main advantages you can note the lightning gear, excellent fuel economy indicators and certainly the dynamics. On an example of Octavia 3 generations with only 180, a strong motor, the Czech car was able to leave far behind competitors with more powerful and bulk motors. Octavia A7 with a 1.8 liter engine perhaps one of the fastest cars in its class and the price segment, faster only more dear cars In sports modifications.

Reviews about DSG-7 car owners Volkswagen

In order to learn about all the advantages and minuses of the robot, we decided to chat with the owners of Volkswagen car owners and learn their opinion on reliability.

• Volkswagen Passat.

Alexander, with her opinion, shared Alexander with us for more than 4 years in possession of the Sedan Volkswagen Passat with a 1.8 liter engine.

First of all, I'll start with the fact that the car I acquired a new one and for a long time to take with a volume of 1.4 or 1.8 liters, because I often go along the track decided all the same to stop my choice on the larger motor, because I think that he loads at high speeds withstand better than a slightly disciplier, which is more suitable for those who exploit the car only in the city. As for the gearbox, it was originally planning to take the mechanics, because Heard about the problems of the robot, moreover, one of the acquaintances was at 48,000 km run. However, having studied the forums with the reviews of the owners concluded that over the past few years, engineers have managed to save DSG from all flaws and the box has become more reliable, as a result of which the choice fell on a version with a robot, which never regretted. For all the time of operation, the car did not deliver any problems and please me to this day.

Of the minuses, I can only notice the unpleasant sound of the metal when moving through lying police or other irregularities. It seems that in the box, the burdens of the well-established mechanism poured bolts, which when shaking are fighting each other. The trip to the dealer did not give any results, besides, judging by the forums, this is a common problem with which official dealer Nothing can do nothing and meets only excuses - they say that it does not affect the work of the transmission, and the fact that the disconnected rattle is not a malfunction, but only is a feature of DSG 7 with dry clutch.

Passat B8.

All good dayI call Constantine and here is my feedback about the DSG box, which many are so afraid. Before, I want to note that before that I had Octavia A7 which I sat down in everything, but I wanted a bigger car, first I wanted to take a new Superb, but having visited the Volkswagen dealer and rummaged at the new Passat, I decided to stop the choice on it. Funds were enough only to version with a 1.4 liter engine, I wanted of course more powerful version with 180 strong motors, but paying about 1,900,000 for me it is expensive, and 150 hp For ride in the city, it is enough completely.

As for the transmission, the choice was definitely the choice was in favor of the robot, because I am not a lover of "pulling" the handle of the gearbox and harrow on the pedals, I really worst me this occupation, after work I want to get to the house with comfort. Because As I have already written above, I had experience of operating a car with an identical transmission and with reliability and disadvantages I am not familiar with the hearse, everything suits me completely, but I somehow do not want to transplanted to the standard automatic machine. After DSG, the work of the classic automatic transmission seems too thoughtful and fuel consumption played a role. With the correct operation of the DSG should not cause any complaints if you encounter this gearbox for the first time, then be sure to read the instructions for the correct operation in the book, which will avoid breakdowns and failure of mechatronics.

Volkswagen Jetta.

My name is Kirill Vasilyevich and this is my feedback about the robot DQ200. I bought a car not new, but with a mileage of 50,000 km, initially wanted to find with an atmospheric engine and a classic hydrotransformer, but we did not sell such cars in the city. An advertisement for the sale of a version with a turbo engine and a robot DQ200 was caught on the eyes, honestly, two things were bribed - the first price of the car and its second dynamics along with low fuel consumption.

The first time the car was pleased with everything and handling and dynamics and imperceptible gear shifting, but after 6,000 km, problems began - the box began to kick when switching gears from the second to the third, and the pinks are strong enough and tangible. Moreover, a distinct clang of metal comes to ride on the uneven road. The trip to the dealer ended with the sentence of the failure of the mechatronics, the benefit of the car was still under warranty warranty. I am afraid that the breakdown may repeat, and the repair will have to do from his pocket, so I plan to put a car for sale in the near future.

Golf MK7.

i will immediately say that the purchase made rather not heads rather, and the heart, because A very long dreamed of this German hatchback. Practically with the advent of the first photographs of the seventh generation began to study all the information about him, including about the DQ200's robot, which judging by the numerous dissatisfied reviews of the owners, caused a lot of issues on reliability. By the way, the main problems came to the first year, then the company gradually corrected all the shortcomings of the design. The main problem was overheating the clutch and the exit of it because of frequent switches from 1 to the second transmission and back while traffic. This problem was solved by reprogramming and increasing the first gear, more precisely, the transmission is switched much later, which reduces the number of transmissions to the second. I hope it is clear what I wanted to say. I approached this issue with a full responsibility and read a sufficiently large number of tips on how to extend the life of the DSG DQ200, including manuals for the correct operation in which it is said that it is better at long parking (In the traffic jam or on the traffic light) switch to Non-Non (N), and with a dense motion or use sports mode (S), or manual gear shift mode. Yes, of course, in this sense, the classic automatic machine is much more convenient and easier, but the sensations that DIRECT SHIFT Gearbox gives, I will not miss anything, I really like to feel the constant acceleration and the lack of a sense of gear shift, as on the automatic transmission.

Now my golf raided 33,400 km and for all this time I had no problems (pah-pah-pah), but of course the mileage is completely meager, but now we can say that the DQ200 robot in 2017 has become much more reliable than the first His versions. In the future, I plan to buy a car also on the robot, but I hope that it will be either a 6-step with a wet clutch DQ250, or, with wet clutch and family of transfers, which today is considered the most reliable among robotic transmissions at VAG.

Volkswagen. Polo Sedan. GT.

Before that, I already had a polo sedan, but with an ordinary machine, I liked the car to everyone, but did not have enough speakers. Immediately after the information about the version of the version C, he thought about his purchase. The dynamics are really interesting when taking into account that the motor volume is only 1.4 liters, and the power of some 125 hp I heard that there are specialists who raise the engine power to 180 and 200 hp True, then the question arises about the reliability of the transmission and its ability to cope with the increased power.

To date, the mileage is 13,600 km. And for all this time there were no problems noted. Working PPC, more precisely, gear shifting is much greater than on a classic machine. So buying is happy for all 100 percent. How will the DQ200 behave in the future will show time, I hope that up to 100,000 km, no problems will happen to her.

Reviews about DSG Owners SEAT

Though this brand Once again, our market left, we could not not include the reviews of the owners to our list.

SEAT LEON

The car was chosen between Skoda Octavia, Audi A3, Seat Leon and Volkswagen Golf.. I wanted a quick car with bright appearance and pleasant salon. Audi dropped due to high prices, Golf due to the lack of 1.8 liter motor, strange why the entire VAG line except this hatchka is equipped with a 180 strong motor, but oh well. As a result, the choice was between Octavia and Lyon. Czech Liftbek was much practical at the expense of the trunk, and the salon is much spacious, but appearance And the design of the Seat of Mnya bribed with the result of which my choice was stopped on this brand.

Unfortunately about the DSG on the seat, I knew what I knew, and the information is not so much on the Internet, it is understandable because This brand is not particularly popular in Russia. But I realized that the box and the engine at Leon is completely similar to those that are installed on Octavia. Therefore, forums of versions of versions with 180 strong engine and transmission were thoroughly studied by me. I was immediately pleased that negative reviews It is extremely small and there is no such volume of complaints as it was for the first generation of Passat B7 with DSG.

Of course, I am afraid of the breakdown of mechatronics and clutch, because The campaign is this most common problem, but while the robot seems to cope with its tasks with a bang. It is a pity, of course, that Leon is not equipped with DQ250, which is more reliable and allows you to slightly increase power without concerning the failure of the failure.
