Embodiment Construction

[0039] Such as figure 1 and figure 2 As shown, the embodiment of the present invention provides a dual-clutch automatic transmission for vehicles, including a first input shaft 1 and a second input shaft 2 . Wherein, the second input shaft 2 is coaxially sleeved on the outside of the first input shaft 1 , that is, the first input shaft 1 is a solid input shaft, and the second input shaft 2 is a hollow input shaft.

[0040] figure 1 The shown dual-clutch automatic transmission includes a first clutch K1 and a second clutch K2. Wherein, the first clutch K1 is connected with the first input shaft 1 , and the second clutch K2 is connected with the second input shaft 2 . The first clutch K1 and the second clutch K2 are respectively arranged on the same side of the first input shaft 1 and the second input shaft 2 .

[0041] exist figure 1 Among them, along the axial direction of the first and second input shafts 1, 2, a first driving gear 9, a second driving gear 7, a third dr...

Abstract

The invention provides a double-clutch automatic gearbox for a vehicle. The double-clutch automatic gearbox for the vehicle comprises a first input shaft, a second input shaft, a first clutch, a second clutch and four driving gears. The first driving gear is meshed with a first-gear driven gear and a third-gear driven gear respectively. The second driving gear is meshed with a fifth-gear driven gear and a seventh-gear driven gear respectively. The third driving gear is meshed with a sixth-gear driven gear and an eighth-gear driven gear respectively. The fourth driving gear is used both as a second-gear driving gear and a fourth-gear driving gear and meshed with a second-gear driven gear and a fourth-gear driven gear respectively. By the arrangement, the axial dimension of the eight-gear double-clutch automatic gearbox of the embodiment is reduced to the maximum extent, so that the eight-gear double-clutch automatic gearbox of the embodiment is small in overall size and is more likely to be carried in the vehicle.

Description

technical field [0001] The invention relates to automatic transmission technology, in particular to a dual-clutch automatic transmission for vehicles. Background technique [0002] With the continuous reduction of non-renewable oil resources and the increasing pollution of vehicle exhaust to the environment, countries have increasingly stringent requirements for vehicle fuel consumption and emission regulations. The transmission efficiency of the transmission system has a great influence on the fuel consumption of the vehicle, and the development of high-efficiency and energy-saving automatic transmissions has become the focus of research and development by domestic and foreign car companies. Traditional automatic transmissions (AT) and continuously variable automatic transmissions (CVT) use hydraulic torque converters with low transmission efficiency, and the maximum comprehensive transmission efficiency can only reach about 85%, while the transmission efficiency of dual-cl...
