The reasons why Audi a6 allroad uses a dual-clutch gearbox:
1. The dual-clutch gearbox can improve the car's shifting speed and transmission efficiency;
2. One clutch of the dual-clutch gearbox is used to control the odd-numbered gears, and the other clutch is used to control the even-numbered gears;
3. Using a dual-clutch gearbox can improve the fuel economy of the car;
Dual clutch originated from the patent applied for by Kegresse.A in Germany in 1939. It first proposed the design concept of dividing the manual transmission into two parts, one part transmits odd-numbered gears and the other part transmits even-numbered gears, and its power transmission Two clutches connect two input shafts, and the passive gears of adjacent gears mesh with the two input shaft gears alternately. With the control of the two clutches, the transmission ratio can be converted without cutting off the power, thereby shortening the shifting time. Effectively improve shift quality.
