Is the principle of conventional at and dual clutch s-shift the same?

The principle is pretty much the same, but the 2 have different controls.

The concept of dual clutch transmission has been around for 60 or 70 years by now. As early as 1939, Germany's Kegresse.A first applied for a patent for dual clutch transmission, put forward the manual transmission is divided into two parts of the design concept, one part of the transmission of odd-numbered gears, the other part of the transmission of even-numbered gears, and its power transmission through the two clutches coupled to the two input shafts, the passive gears of the neighboring gears staggered with the two input shafts gears mesh with the two clutch control, can be realized without cutting off the power. With the control of two clutches, it can realize the conversion ratio without cutting off the power, thus shortening the shift time and effectively improving the shift quality.

The clutch is located between the engine and transmission, is the engine and transmission power transfer "switch", it is a kind of power transfer, but also cut off the power transmission mechanism. Its role is to ensure that the car can start smoothly, gear shift to reduce the impact of the gear wheel load and prevent the transmission system overload. In general automobiles, the automobile shift through the clutch separation and engagement to realize, in the separation and engagement between the power transmission temporary interruption of the phenomenon. This has no effect on ordinary cars, but in the race car, if the clutch is not good enough to keep up with the power, the car will slow down, affecting the results.
