Abstract

The invention discloses a nine-speed double-clutch type automatic speed changer transmission structure and a vehicle. First-gear, second-gear, third-gear, fifth-gear, sixth-gear, ninth-gear, fourth-gear, seventh-gear and eighth-gear driving gears are arranged on an input shaft; first-gear, second-gear, fifth-gear, sixth-gear, seventh-gear and eighth-gear driven gears and a reverse-gear driving gear are arranged on a first output shaft; third-gear and ninth-gear driven gears are arranged on a second output shaft; a fourth-gear driven gear is arranged on a third output shaft; first-gear, second-gear, third-gear, fourth-gear, fifth-gear, sixth-gear, seventh-gear, eighth-gear and ninth-gear driven gears and the reverse-gear driving gear achieve corresponding shaft-gear transmission through a synchronizer; a reverse-gear driven gear is fixed to the third output shaft; first, third and fourth main reduction gears are respectively fixed to the first, second and third output shafts; a third clutch is connected with a second main reduction gear and the first output shaft; the first and third main reduction gears mesh with a first differential mechanism main reduction gear; the second and fourth main reduction gears mesh with a second differential mechanism main reduction gear; and the first and second differential mechanism main reduction gears are connected with a differential mechanism assembly through first and second clutches respectively. The axial size is short, the dynamic property and economical efficiency requirements are met, the gear shifting time is short, and the gear picking and shifting noise is avoided.

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...
