Abstract

The invention discloses an automobile dual-clutch transmission gear shifting mechanism. The automobile dual-clutch transmission gear shifting mechanism structurally comprises a power input shaft, two clutch input shafts, two middle shafts and an output shaft. The power input shaft is provided with an input shaft gear. The clutch input shafts are respectively provided with clutch input shaft gears and combined hydraulic clutches. Output hubs of the combined hydraulic clutches are respectively connected to a sun gear and a ring gears. The sun gear and the two ring gears are respectively provided with a brake controlling the rotation of the sun gear and the ring gears. The two middle shafts are respectively connected to two planetary gear carriers and provided with a synchronizer and middle shaft output gears. A reverse gear shaft is sequentially provided with a reverse gear shaft input gear, a synchronizer and a reverse gear shaft output gear. Two output shaft output gears are mounted on the output shaft and meshed with the two middle shaft output gears. The automobile dual-clutch transmission gear shifting mechanism has the advantages of having multiple gears and being simple in shifting control and available in gear segment configuration and can achieve 12-gear shift.

Description

technical field [0001] The invention relates to the field of transmissions, in particular to a speed change mechanism of a dual-clutch transmission for automobiles. Background technique [0002] Now domestically produced dual-clutch automatic transmissions are mostly fixed-shaft gears, and the number of shifting gears and the range of gear transmission ratios that can be obtained are relatively limited. Due to the small number of gears in daily driving, the gearbox is faced with the dilemma that there is no gear to increase in the higher driving speed range, forcing the car engine to maintain a high speed, shortening the service life of the engine, and increasing the energy consumption of the engine. The current dual-clutch automatic transmission needs to increase gears, usually by increasing the length or number of transmission shafts and output shafts, thereby putting forward higher requirements on the stiffness of the shafts, resulting in an increase in the overall size o...
