The dual clutch transmission (DualClutchTransmission) DCT different from the general automatic transmission system, which is based on the manual transmission but is not an automatic transmission, manual transmission in addition to the flexibility and comfort of an automatic transmission, but also can provide uninterrupted power output. The traditional use of a manual transmission clutch, when the shift, the driver must depress the clutch pedal, so that the different gears to make gear meshing operation, and the power interruption occurs during a shift would make intermittent output performance has .
1. The advantages and disadvantages of a dual clutch transmission
Compared with the conventional manual transmission, more convenient, faster, smoother shift ratio DCT manual transmission, uninterrupted power output.
It eliminates manual transmission torque interruption when shifting feeling, the driver more sensitive.
based on their use manual transmission as the basis for its unique design, DCT can withstand up to 350 Nm of torque.
The disadvantages are: the complicated structure of the double clutch transmission, the manufacturing process required relatively high, so the cost is relatively high.
While affordableThe torque, dual-clutch transmission has been absolutely able to meet the general requirements of the vehicle, but not enough for intense use.
2. dual-clutch transmission history
In 1940, Darmstadt University professor RudolphFranke first applied for a patent dual-clutch transmission, the transmission has been tested on a truck, but did not put into mass production.
Subsequently the invention is also dedicated to a Porsche car dual clutch transmission.
In 1985, Audi will double-clutch technology in the racing field, was named “AudiSportQuattroS1 car with dual clutch technology.”
double-clutch technology enables the Audi car was driving in the major cross-country track and win more races.
In 2002, DCT application in Germany, Volkswagen Golf R32 and Audi TTV6.
in 2003, which have been extended to golf and other models.
In 2004, DCT first match with the TDI diesel engine in the Volkswagen Touran (Touran) models.
DCT for its excellent fuel economy and become the “new favorite” in Europe.
BorgWarner DCT new projects put into operation in 2007, mainly luxury passenger cars, sports facilities, annual production capacity of 600,000 sets.
