Description

Ten keep off two separation and reunion derailleurs and vehicle
Technical Field
The invention belongs to the technical field of vehicle transmissions, and particularly relates to a ten-gear double-clutch transmission and a vehicle.
Background
The double-clutch type automatic transmission integrates two gearboxes and two clutches into a gearbox shell, two inner input shafts and two outer input shafts which are rotatably sleeved are respectively connected with one clutch, the two input shafts respectively transmit power of two gearbox speed groups, and a gear shifting program is completed by automatic switching between the two clutches, so that the continuity of the power in the gear shifting process can be realized, namely, the power is not interrupted in the gear shifting process, the defect of AMT gear shifting impact is overcome, the power of an engine can be always transmitted to wheels in the gear shifting process of a vehicle, the gear shifting is rapid and stable, the acceleration of the vehicle is ensured, and the rapid deceleration condition caused by gear shifting is not generated any more by the vehicle, and the running comfort of the vehicle is greatly improved. However, since the conventional double clutch type automatic transmission mostly uses dual output shafts or a single output shaft and uses a common drive gear or a linearly arranged gear train, its axial dimension is long, so that it is difficult to adopt the above-mentioned transmission for a vehicle such as a front transverse engine or a front wheel drive, particularly a small vehicle, because its installation space is limited, and it is difficult to work the engine in an optimum working area because of its few gears for shifting, thereby adversely affecting the power performance and economy of the whole vehicle.
There is a twin-clutch manual transmission which includes a first input shaft and a second input shaft to which engine rotation is selectively input via separate clutches. A first gearset associated with the first gearbox speed grouping is located between the countershaft and an aft end of the projecting first input shaft. A second gearset associated with a second gearbox speed grouping is located between the second input shaft and the layshaft. The gearbox realizes the speed reduction transmission between the input shaft and the output shaft through only one auxiliary shaft.
Therefore, the conventional double-clutch automatic transmission generally adopts a structural form of a single output shaft or double output shafts, and the whole length of the transmission is long, so that the transmission is difficult to apply to front-transverse front-drive vehicle types. Moreover, the structural form of the single output shaft or the double output shafts leads to that the existing double-clutch automatic transmission has a larger structure, and has fewer gears which can be arranged under the condition of the same transmission size, so that the engine is not beneficial to work in the best region.

The center distance between the inner input shaft and the outer input shaft and between the three output shafts can be designed to be smaller, and the structure is more compact. Reverse gear transmission route is simple, utilizes 2 to keep off driving gear and 2 fender driven gear commutations, has reduced gear engagement quantity, and the transmission is more steady, and efficiency is higher.
In addition, the embodiment of the invention also provides a vehicle which comprises the ten-gear double-clutch transmission of the embodiment.
