Ten-speed dual-clutch automatic transmission

Abstract

An automatic ten-gear double-clutch transmission comprises an inner input shaft, an outer input shaft, a first inner output shaft, a first outer output shaft, a second inner output shaft and a second outer output shaft, wherein the inner input shaft is embedded in the outer input shaft, the first inner output shaft is embedded in the first outer output shaft, and the second inner output shaft is embedded in the second outer output shaft. According to the automatic ten-gear double-clutch transmission, the two sets of embedded type output shaft structures are adopted, the two output shafts arranged in an embedded manner in each set transmit power through a synchronization device, and through a gear borrowing manner, ten advancing gears and one reverse gear are achieved; and the whole transmission is compact in structure, small in axial size, small in required mounting space, simple in structure and easy to machine, ten gears can be set on the premise that the profile size is the same as that of a common seven / eight-gear transmission, and transmission ratio distribution is more reasonable, so that an engine can work on the optimum region as much as possible, and dynamic property and economical efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of vehicle transmissions, in particular to a ten-speed dual-clutch automatic transmission. Background technique [0002] Dual Clutch Transmission (DCT) integrates two gearboxes and two clutches into one gearbox, two rotatably nested input shafts are respectively connected to one of the clutches, and two The input shaft transmits the power of the two gearbox speed groups respectively, and the gear shifting procedure is completed by automatically switching between the two clutches, so the power shifting process of the shifting process can be realized, that is, the power is not interrupted during the shifting process, and the overcoming The shortcomings of the electric control mechanical automatic transmission (Automated Mechanical Transmission, AMT) shift shock, the power of the engine can always be transmitted to the wheels during the shifting process of the vehicle, and the shifting is fast and smooth, which...

Problems solved by technology

[0003] However, most of the existing dual-clutch automatic transmissions adopt dual output shafts or single output shafts, so their axial dimensions are relatively long, so for vehicles such as front transverse engines and front-wheel drives, especially small cars, due to their installation Due to the limited space, the above-mentioned transmission is difficult to adopt, and because it has fewer shifting gears, it is difficult to achieve a reasonable distribution of the transmission ratio, making it difficult for the engine to work in the optimal working area, thus affecting the power and economy of the vehicle.
