Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile double clutch gearbox can body blank, especially a can body blank. BACKGROUND

[0002] Double clutch gearbox is called DCT for short, and many people call it double clutch transmission because it has two clutches. The clutch is located between the engine and the transmission and is the "switch" of power transmission between the engine and the transmission. It is a kind of transmission mechanism that can transmit power and cut off power. Its main function is to ensure that the automobile can start smoothly, reduce the impact load of the transmission gear during gear shifting and prevent the transmission system from overloading. On a general automobile, the clutch is separated and engaged during automobile gear shifting, and there is a phenomenon of temporary interruption of power transmission between separation and engagement.
