I continue to tell you what and how it works in the car. And today I want to tell you what it is -. This is a development of Volkswagen, which is put on many car brands. Such as Volkswagen, Seat, Skoda, Fiat and even some Audi models. So when you read the equipment of a car for all these brands, you can see the abbreviation "DSG", but what do you know? No! Then read on……..
A DSG gearbox or fully Direct Shift Gearbox (synchronized shift gearbox) is a combination of manual and automatic transmissions when an automatic or mechanic is needed. Quite complicated, in the device, but very practical. By the way, this is the first gearbox that uses two clutch discs, due to which the shifting is almost jerk-free and much faster than a classic automatic transmission with a single clutch disc. In addition, along with two clutch discs, there are five shafts in the design. Through these five shafts and two clutch discs, as well as connecting gears, it forms a two-circuit mechanism. Therefore, the car picks up speed as quickly as a manual transmission, and according to the latest test measurements, even much faster. No wonder these boxes are used in all kinds of motorsport competitions, such as rallies. But wait, what about the mechanics, you ask? After all, you wrote that it is combined with mechanics? Yes, indeed, for the first time they began to install the so-called Tiptronic (Manual linear gear shifting), by the way, the Tiptronic control is located not only on the gear lever, but also on the steering wheel of the car, implemented with buttons.
DSG box device
Transmission - designed so that the two shafts are freely located inside. Moreover, they are located on the same axis. The thing is that one shaft is hollow, and the second shaft passes through the first. The first shaft and its group of gears form the first circuit, it switches the second, fourth and sixth gears. The second shaft accordingly creates its own circuit, which is responsible for switching the first, third, fifth and reverse gears. Therefore, the speed of gear shifting is very fast, while one shaft is in first gear, then the second one has already prepared the second gear, and so on. This process is electronically controlled, but with the help of a hydraulic booster.
Now some facts
Turbocharged Volkswagen Golf, with a manual transmission, accelerates to 100 km / h in 6.6 seconds. The same Golf, but with a DSG gearbox, accelerates in 6.3 seconds, despite the fact that its weight is greater. Also, the consumption of a car with such a transmission is 1.3 liters less. It's worth thinking about. Many manufacturers, including the Japanese, adopted a lot from the Germans, Japanese analogues of DSG boxes appeared much later. No wonder the Germans are called the kings of the automotive industry.
