Problems solved by technology

However, this kind of transmission mechanism has the following disadvantages: since the two wet clutches are respectively fixed on the two input shafts, one of the input shafts is tubular and is sleeved on the other input shaft, and the other input shaft distributes its gears to the tubular Except for the end of the shaft, this arrangement increases the size, weight and price of the transmission mechanism, and is not easy to install on small vehicles

Embodiment 1

[0020] Embodiment 1: as figure 1 and figure 2 As shown, a dual clutch automatic transmission includes an input shaft 25 integrally provided with an input sprocket 1; an intermediate shaft 8; a first layshaft 7; a second layshaft 3; the input shaft 25, the second layshaft A secondary shaft 7 and the second secondary shaft 3 are parallel to each other; a first clutch 6 fixed on the first secondary shaft 7; a second clutch 2 fixed on the second secondary shaft 3; a power input device and power output device; first clutch 6, first clutch sprocket 23, fifth gear driving gear 13, fifth reverse gear synchronizer 22, reverse gear driving gear 14, third gear driving gear 11. First and third gear synchronizer 20 and first gear driving gear 9; second clutch 2, second clutch sprocket 24, countershaft sprocket 4, fourth gear driving gear 12, second gear are arranged in sequence on the second countershaft 3 The fourth gear synchronizer 21 and the second gear driving gear 10; the fourth a...

Embodiment 2

[0034] Embodiment 2: The difference between this embodiment and the embodiment is that the second clutch 2, the countershaft sprocket 4, the second clutch sprocket 24, the fourth gear driving gear 12, the second Fourth-speed synchronizer 21 and second-speed driving gear 10 . Other structures of this embodiment are the same as those of Embodiment 1. The power transmission route of this embodiment is the same as that of Embodiment 1.

Abstract

The invention relates to a double-clutch automatic transmission, which comprises an input shaft (25), an intermediate shaft (8), double countershaft, a first clutch (6), a second clutch (2), a power input device and a power output device, wherein the countershaft comprises a first countershaft (7) and a second countershaft (3); the first clutch (6) is fixed on the first countershaft (7); the second clutch (2) is fixed on the second countershaft (3); and the power input device is a sprocket drive device. The transmission has the advantages of small gear quantity, small axial length and light weight, and is easier to be arranged and used in a small-size front-wheel drive car.

Description

technical field [0001] The invention relates to a vehicle transmission, in particular to a dual-clutch automatic transmission. Background technique [0002] The existing dual-clutch automatic transmission includes two clutches, a shift synchronizer, a shift control system, an electronic control system TCU and a six-gear transmission. The two wet clutches are respectively fixed on two countershafts. The driving gears of the first and even gears are respectively driven and connected with two wet clutches, and the two clutches alternately transmit working power to realize the switching between the gears. However, this kind of transmission mechanism has the following disadvantages: since the two wet clutches are respectively fixed on the two input shafts, one of the input shafts is tubular and is sleeved on the other input shaft, and the other input shaft distributes its gears to the tubular Except for the end of the shaft, this arrangement increases the volume, weight and pric...
