Abstract

The transmission structure of the nine-speed dual-clutch automatic transmission and the vehicle of the present invention, the first, second, third, fifth, sixth, ninth and fourth, seventh and eighth gears are arranged on the input shaft; It is set on the first output shaft, the third and ninth gears are set on the second output shaft, the fourth gear is set on the third output shaft, and the first to ninth gears and the reverse driving gear are all synchronized through the synchronizer. shaft gear transmission; the reverse driven gear is fixed to the third output shaft; the first, third and fourth main reduction gears are respectively fixed to the first, second and third output shafts, and the third clutch is connected to the second main reduction gear and the first Output shaft; the first and third main reduction gears mesh with the first differential main reduction gear, the second and fourth main reduction gears mesh with the second differential main reduction gear, the first and second differential main reduction gears respectively The differential assembly is connected through the first and second clutches. The axial dimension is short to meet the needs of power and economy, the shifting time is short, and there is no shifting noise.

Description

technical field [0001] The invention belongs to the field of transmissions, in particular to a transmission structure of a nine-speed dual-clutch automatic transmission and a vehicle. Background technique [0002] Most of the existing dual-clutch automatic transmissions adopt a dual-input-shaft-double-output-shaft structure or a dual-input-shaft-single-output-shaft structure, resulting in a longer axial dimension of the automatic transmission. Therefore, for front-wheel-drive vehicles, the cabin space is greatly limited and cannot be realized. The multi-gear of dual-clutch automatic transmission is not conducive to the power and economy of the vehicle. The shifting process of dual-clutch automatic transmission has high requirements on the control of shift forks and clutches, and the whole vehicle is prone to problems such as shifting noise, clutch engagement and separation noise, tooth knocking noise and shifting shock. Contents of the invention [0003] The technical pro...
