Each gm tech2 company's dual-clutch transmission

Volkswagen DSG (Direct Shift Gearbox). Mentioned  gm tech2 dual-clutch transmission, most riders first thought is Volkswagen's DSG ® dual-clutch transmission technology. Indeed, Volkswagen's DSG ® is a motor racing today the most widely used dual-clutch transmission technology, is the most suitable for the mass production of the transmission technology, which uses six or seven forward gears traditional gear transmission as power transmission components , the main platform with the high torque engine with use.
Volkswagen in Wolfsburg, Germany, in 2002 for the first time to show the world the representative works of this technological innovation - the Golf GTI. DSG ® transmission shaft is divided into two, one is placed on the inside solid drive shaft, and the other outside the hollow drive shaft; the inside solid drive shaft connected to the 1,3,5 and after files, and outside the hollow drive shaft connected to 2,4 and 6-speed, two clutch engagement action each responsible for a drive shaft, engine power will make a seamless transfer by which a drive shaft. Judging from the layout, this transmission length is very short (equivalent to half the length of the traditional six-speed transmission), so can be used to pre-precursor models.
Equipped with the DSG ® transmission engine fast gear conversion can immediately generate traction and greater flexibility, the   launch x431 acceleration time is faster than the manual transmission. Golf GTI with DSG ® models 0-100 km acceleratioin just 6.9 seconds, this result is faster than the manual transmission models, to reach a maximum speed of 235 kilometers per hour, while at the same level. More impressive is the improvement in performance at the same time, with the DSG ® models 100 km fuel consumption of only 8.0 liters of manual models.
To manipulate the DSG ® transmission, the driver can use the shift piece on the gear lever or the steering wheel to the sequential manual shift, shift process clutch DSG ® computer-controlled operation completely by. Use the manual mode, whether moving or D or S automatic shift mode, as long as Pat the shift piece on the steering wheel, DSG ® immediately switch to manual mode and shift programs, there is no traditional automatic transmission hard acceleration when The lag a sense.

Audi S Tronic. S-Tronic technology is known as a direct shift transmission, S-Tronic uses two sets of clutch series. Transmission   renault can clip shift fast compared with ordinary transmission, equipped with this transmission vehicle acceleration and fuel economy is greatly improved. At present, only the Audi TT and Audi A3 is equipped with this technology, so that they can be completed within 0.2 seconds arbitrary switching between six stalls, and will not cut off the power output.
