DCT includes two automatic clutches, which are driven by electric control and hydraulic pressure, and can control the work of both clutches at the same time. When the transmission is running, one set of gears is in the engaged state, and when it is close to shifting, the gear of the next set of gears has been pre-selected, but the clutch is still in the disengaged state; When shifting gears, one clutch is disengaged from the gear in use, and the engagement of the other clutch is pre-selected, so that at least one gear can output power during the whole shifting period without power interruption. In order to cooperate with the above operations, the transmission shaft of DCT is divided into two parts, one is a solid transmission shaft and the other is a hollow transmission shaft. The solid drive shaft is connected to 1, 3, 5 and reverse gear, and the hollow drive shaft is connected to gear 2, 4 and 6. The two clutches are respectively responsible for the meshing action of a transmission shaft, and the engine power will be continuously transmitted by a transmission shaft.
Based on the manual transmission and its unique design, DCT can resist the torque as high as 350 Nm, and the precise computer calculation has more accurate shift control than the general manual transmission, so DCT has also become a more fuel-efficient transmission system. Based on the characteristics and working mode of DCT, DCT system can bring drivers the same feeling as driving a racing car. In addition, the torque interruption during manual gear shifting is eliminated, and driving is more sensitive.

abstract
A dual clutch transmission (1) used in an automobile is provided with a dual clutch device (2), which includes a first clutch (3) and a second clutch (4), and these clutches have the same rotation axis (8); A first input shaft (9) and a second input shaft (10), wherein the first input shaft is connected with the engine (6) through a first clutch, and the second input shaft is connected with the engine through a second clutch; A plurality of interchangeable gear pairs (1 1, 12, 29) connecting the input shaft with at least one output shaft; A first drive unit (37) and a second drive unit (38), through which a series and/or parallel hybrid mode of the dual clutch transmission can be realized. The first drive unit is coaxially arranged with the clutch and surrounds them in the radial direction, and the second drive unit has a drive shaft with a rotation axis (44) different from that of the clutch.
Sovereignty terms
Claim 1. A dual clutch transmission (1), especially for automobiles, has a dual clutch device (2) which includes a first clutch (3) and a second clutch (4), wherein the first clutch (3) and the second clutch (4) have the same characteristics. It has a first input shaft (9) and a second input shaft (10), the first input shaft (9) can be connected with the engine (6) through a first clutch (3), and the second input shaft (10) can be connected with the engine (6) through a second clutch (4); Having a plurality of interchangeable gear pairs for connecting the input shaft (9, 10) with at least one output shaft (1 1, 12, 29); And has a first driving unit (37) and a second driving unit (38), through which a series and/or parallel hybrid mode of the dual clutch transmission (1) can be realized, and is characterized in that the first driving unit (37) is coaxially arranged with the first and second clutches (3, 4) and surrounds these clutches (3) in the radial direction.
