The concept of dual-clutch transmission has a history of sixty or seventy years. As early as 1939, Germany's Kegresse.A was the first to apply for a patent for a dual-clutch transmission and 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 is connected to two input shafts through two clutches. The driven gears of adjacent gears are interleaved with the two input shaft gears and cooperate with the two clutches. The control can realize the transmission ratio conversion without cutting off the power, thereby shortening the shifting time and effectively improving the shifting quality.

Characteristics of dual clutch
1. DSG vehicles will not feel power interruption during acceleration, making the vehicle's acceleration more powerful , sleek. The acceleration time to 100 kilometers is shorter than that of a traditional manual transmission.
2. The power transmission component of the DSG transmission is a three-shaft traditional gear transmission with 6 forward gears, which increases the distribution of speed ratios.
3. The multi-plate wet dual clutch of the DSG transmission is controlled by an electronic hydraulic control system. ※The use of dual clutch allows the transmission to engage two gears at the same time, making the gear shifting operation faster.
4. The DSG transmission also has two control modes: manual and automatic. In addition to the gear lever, the steering wheel is also equipped with a manually controlled shift button. During driving, you can switch between the two control modes. Switch anytime.
