Abstract

The invention relates to a nine-speed dual-clutch automatic transmission and a vehicle, wherein the nine-speed dual-clutch automatic transmission comprises: an input shaft including a first input shaft, a second input shaft and an input gear shaft; an output shaft including a first intermediate shaft and the second intermediate shaft. The first intermediate shaft is provided with a first output gear, a first double-sided synchronizer, a first output gear shaft, a fourth output gear and a first single-sided synchronizer, and the first output gear shaft is provided with a third output gear and a second double-sided synchronizer. Synchronizer; the second intermediate shaft is provided with the fifth output gear, the third bilateral synchronizer, the second output gear shaft, the eighth output gear and the second single-sided synchronizer, and the second output gear shaft is provided with the seventh output gear and Fourth bilateral synchronizer. The nine-speed dual-clutch automatic transmission is improved on the basis of the existing seven-speed dual-clutch transmission. While completing nine-speed shifting, it can maximize the number of core output gears and synchronizers, and is compact in structure and takes up space. smaller.

Description

technical field [0001] The invention relates to the field of automobile transmissions, in particular to a nine-speed dual-clutch automatic transmission and a vehicle. Background technique [0002] The dual-clutch automatic transmissions currently on the market are mainly 6-speed and 7-speed. With the upgrading of national emission standards, in order to improve the fuel performance of vehicles, major manufacturers are developing and researching gearboxes with more gears. [0003] With the development of today's automobile industry, energy saving and emission reduction have become the main direction of design, and the requirements for the design of transmissions in vehicles are becoming more and more stringent. Therefore, dual-clutch automatic transmissions with high efficiency, high comfort, and high-speed ratio range have gradually become a development trend. The drive train structure and the layout of the parking ratchet in the dual clutch automatic transmission are impor...
