Shift process for example:
One gear changes the process of reversing gear: dual-clutch transmission is in a gear, the odd number gear clutch C1 work, the even number
It keeps off clutch C2 to open, the 621 gear synchronizer 621 and the gear driven gear 21 combine；It is sent out when receiving driver
It is reversed gear after signal out, after dual-clutch transmission control system (not showing in attached drawing 1) confirms that speed is 0, double clutch speed change
Device control system issues a gear and changes instruction of reversing gear, and the 621 gear synchronizer 621 and the gear driven gear 21 separate, institute
Odd number gear clutch C1 separation, the reverse gear synchronizer RS and the combination of driven gear 20 of reversing gear are stated, shift process is terminated；Instead
Come over, reverse gear and change a gear process, when receive driver issue reverse gear signal after, dual-clutch transmission control system confirm vehicle
After speed is 0, the sending of dual-clutch transmission control system, which is reversed gear, changes gear instruction, and the odd number gear clutch C1 keeps combining,
The reverse gear synchronizer RS and the separation of driven gear 20 of reversing gear, the 621 gear synchronizer 621 and a gear are driven
Gear 21 combines；So whether a gear is changed and reversed gear, still reverse gear and change a gear, the odd number gear clutch C1 is individually to locate always
In working condition, the even number gear clutch C2 is not involved in work always, under some conditions, especially small spaces such as library
Interior, this process meeting frequent progress can reduce the frequent transitions of working condition between different clutches, thus when reducing shift
Between, also reduce the abrasion of clutch disc.
One keeps off the process that shifts into second: dual-clutch transmission is in a gear, the odd number gear clutch C1 closure, the even number
It keeps off clutch C2 to open, the 621 gear synchronizer 621 and the gear driven gear 21 combine, at this time 621 gear
Synchronizer 621 and the second gear driven gear 22 are also to combine；Dual-clutch transmission control system (is not shown) in attached drawing 1
It issues one and keeps off the instruction that shifts into second, the even number gear clutch C2 keeps off clutch C2 still in opening state, i.e., the described even number at this time
Do not transmit power；As shift process continues, odd number gear clutch C1 is gradually opened, at the same time, the even number keep off from
Clutch C2 is gradually closed, this process is not in torque break；Odd number gear clutch C1 is fully opened, the even number keep off from
After clutch C2 is closed completely, terminate shift process.
Four gears change five gear processes: dual-clutch transmission is in five gears, the even number gear clutch C2 closure, the odd number
It keeps off clutch C1 to open, four or the eight gear synchronizer 48 and the four gears driven gear 24 combine；Dual-clutch transmission control
System (not showing in attached drawing 1) issues four gears and changes the instruction of five gears, and gear shifting actuating mechanism is in advance by five or nine gear, 59 He of synchronizer
Five gear driven gears 25 combine, and the odd number gear clutch C1 is opened still in opening state at this time, i.e., the described odd number keeps off clutch
Device C1 and the solid input shaft 2 do not transmit power；As shift process continues, the even number gear clutch C2 is gradually beaten
It opens, at the same time, the odd number gear clutch C1 is gradually closed, this process is not in torque break；The even number keeps off clutch
After device C2 fully opens, odd number gear clutch C1 is closed completely, four or the eight gear synchronizer 48 disengage with four gear from
The combination of moving gear 24 terminates shift process.
The foregoing is merely the preferred embodiments of the invention, are not intended to limit the invention creation, all at this
Within the spirit and principle of innovation and creation, any modification, equivalent replacement, improvement and so on should be included in the invention
Protection scope within.
