Now cars are equipped with different types of boxes. The days when machines were the only “mechanics” are long gone. Now, more than half of modern cars are equipped with other types of transmission. Even domestic manufacturers began to gradually switch to automatic transmission. Concern «Audi-Volkswagen” almost 10 years ago introduced a new drivetrain – DSG. What is that box? What is its device? If there are any problems during the operation? All this and not only – further in our article.

Feature DSG

What's this box? DSG is a direct shift transmission. what is a dsgIt is equipped with automatic drive switching speeds. One of the features of DSG "mechatronics" – the presence of two clutches.

Design

This transmission connects to the motor via two coaxially arranged clutch disc. One is responsible for the even-numbered transmission, and the second – for odd and reverse. Thanks to this device the car is going slower. Box provides smooth gear change. How does the machine DSG? Let's take an example. The car goes in first gear. When the gears rotate and transmit torque, the second speed is engaged. It rotates at idle. When the car switches to the next step, is activated the electronic control unit. At this time the hydraulic actuator of the transmission releases the first clutch, and finally closes the second. Torque moves smoothly from one gear to another. And so on until the sixth or seventh gears. When a car attains a high enough speed, the box will switch to the last stage. dsg automaticThis gear penultimate, that is, the sixth or fifth gear, will be “idle” engaged. By reducing the speed of the clutch disks robotic box is shut off the last step and enter into contact with the penultimate gear. Thus, the engine is in constant contact with the box. At the same time, “mechanics” by pressing the pedal pulls the clutch disk and transmission are no longer in contact with the engine. Here if you have two drives, torque transmission is performed smoothly and without interruption of power.

Advantages

Unlike a conventional machine, robotic DSG transmission requires a smaller load, thereby reducing fuel consumption. Also, unlike simple automatic transmission, decreases the time between gear changes. All thanks to two clutches. In addition, the driver can to switch to "Tiptronic" and mechanically control the gear shifting. The function of the clutch pedal will perform electronics. Now the car «Skoda», “Audi” and «Volkswagen» system ECT, which not only controls the shifting, but also controls the throttle opening. Thus, when the drive creates a sense that you are driving one. Electronics also reads a lot of other data, including engine temperature. The manufacturer claims that the use of the ECT system allows to increase the service life of a robotic CAT and engine by 20 percent. dsg mechatronicsAnother plus – choice of operation mode of transmission. There are three: winter, economy and sports. Regarding the latter, the electronics changes the shift point to later. So increasing the engine torque. But fuel consumption also becomes larger.

Problems and faulty transmissions

As robotic DSG transmission is a complex Electromechanical device, it is susceptible to various breakdowns. Let's look at them. So, the first problem – grip. It is worth noting the wear of the basket and the driven disk, and an increased load on the release bearing. The symptom of these mechanisms – slip clutch. As a result of lost torque and deteriorates the dynamics of dispersal of the car. automatic dsgThere is an emergency mode DSG. What does it mean? Light appears on the dashboard, the car gets jerky and bad to start with place.

Aquatory

The DSG Issues relate to acutator. Is an Electromechanical actuator gear shift and clutch. With frequent operation and high mileage wear so-called “brush”. It is not excluded the open circuit of the electric motor. The symptom of acutation – a sharp start and “pulling” car. Also, this symptom occurs due to incorrect settings of the clutch. Therefore, it is necessary to make computer diagnostics. Each brand of car your fault codes.

About the 7-speed DSG

What kind of box, we already know. Fundamental differences in six - and seven-speed “robots” no. dsg problemsBut statistics say that such boxes are most prone to damage. If to consider separately the seven-speed “robot”, it should be noted the problem of the control unit "mechatronics" clutch-dry type. The latter is subject to heavy wear, especially during the transition to a higher or lower gear. As a result, it wears out andbox gets up in “emergency”. Having wheelspin problems at the start and switching speeds. The manufacturer «Volkswagen» gives a warranty period of 5 years. During this time, more than half of the vehicles with this transmission require clutch replacement. This is the whole problem with this transmission. Therefore, if the car more than five years, the responsibility falls squarely on the shoulders of the vehicle owner. And it for your money will change all nodes in this box.

Mechatronics

The Challenges are not only mechanical, but also electrical part, namely the control unit. The element is installed in the transmission. As it is constantly exposed to stress, the temperature inside the node increases. dsg gearboxBecause Of this, burn out the contacts of the unit broken faulty valves and sensors. Also occurs clogging of the channels of the hydraulic unit. Sensors themselves literally minicat themselves the products of wear of the box – small metal shavings. In the result of disrupted electro-hydraulic control unit. The machine starts to slip, badly goes, until the complete stop of operation of units. Also of note is the problem of wear of the clutch fork. In the result box cannot enable one of the transmission. There is a hum when driving. This is due to wear of a rolling bearing. This gearbox is installed on cars of different segment. But even expensive cars are not excluded any of these incidents, although the units are designed for a longer service life and load.

How to extend the life?

In view of the frequent appeals in dealerships, the company began to advise motorists on how to prolong the service life of the box. dsg gearboxTo the elements of the transmission were subjected to less stress, when you stop for more than five seconds, the manufacturer recommends to translate the selector lever in neutral position.

Conclusion

So, we found out that is automated manual. As you can see, despite the many advantages, it has many problems. So ride on such cars is reasonable only if it is in the warranty period. To acquire such cars on the secondary market, if they are more than 5 years, motorists are not advised. The reliability of these boxes is questionable.
