Description
Technical field
The invention belongs to transmission for vehicles technical field, and double-clutch speed changer is kept off more particularly to one kind nine.
Background technology
Double disengaging type automatic transmission are that two gearboxes and two clutches are integrated in a transmission case body, two
The inside and outside input shaft that root is rotatably sleeved in together is connected with one of clutch respectively, and two input shafts pass respectively
The power of defeated two gearbox speed groups, by automatically switching between two clutches so as to complete program of shifting gears, therefore can
The continuation of power in shift process is realized, i.e., interrupts power in shift process, the shortcomings that overcoming AMT shift shocks,
Vehicle in shift process, can shift gears rapid steady for delivery to wheel, not only ensure that vehicle all the time by the power of engine
Acceleration, and because vehicle no longer produces the situation that is a significant slowdown caused by gearshift, also greatly improve vehicle operation
Comfortableness.But because existing double-clutch automatic transmission uses double output shaft or single output shaft more, and use
Driving gear or linear arrangement gear train are shared, therefore its axial dimension is longer, so for preceding transverse engine, front wheel driving
Dynamic such vehicle, particularly compact car, because its installing space is restricted, the just more difficult use of above-mentioned speed changer, Er Qieyou
It is less in the gear of its speed change, make engine is more difficult to be operated in optimum working zone, so as to the dynamic property and economy to vehicle
Have a negative impact.
A kind of existing twin-clutch manual gearbox, the gearbox include the first input shaft and the second input shaft, started
Machine is rotated and selectively inputted on these input shafts through single clutch.First tooth associated with the first gearbox speed group
Wheel group is between the rear end of the first prominent input shaft and countershaft.The second gear group associated with the second gearbox speed group
Between the second input shaft and countershaft.The gearbox only realizes that the deceleration between input shaft and output shaft passes by a countershaft
It is dynamic.
It can be seen that existing double-clutch automatic gearbox typically uses the structure type of single output shaft or double output shaft,
The entire length of reduction box is longer, it is difficult to the speed change needs of the vehicle of horizontal forerunner before being applied to.Also, single output shaft is double
The structure type of output shaft causes existing double-clutch automatic gearbox structure more huge, in the feelings of identical transmission dimensions
The gear that can be arranged under condition is less, is unfavorable for so that engine is in best region work.
The content of the invention
The technical problems to be solved by the invention are：For existing single output shaft or pair of double output shaft structure type
Clutch automatic transmission entire length is longer, it is difficult to the defects of speed change of the vehicle of horizontal forerunner needs before being applied to, there is provided

The nine gear double-clutch speed changer shift process explanations of the present embodiment：
One keeps off the process that shifts into second：During 1 gear, 1/7 gear synchronizer 22 and 1 keeps off driven gear 23 and combined, and second clutch 34 closes
Close, first clutch 33 is opened；Dual-clutch transmission control system send 1 gear change 2 gears instruction after, gear shifting actuating mechanism is advance
2/6 gear synchronizer 25 and 2 is kept off into driven gear 28 to combine, now first clutch 33 is still in open mode, i.e. the first clutch
Device 33 and outer input shaft 1 not passing powers.As shift process continues, second clutch 34 is gradually opened, and at the same time
One clutch 33 gradually closes, and during this, has clutch combination all the time, is not in torque break.Second clutch 34 is complete
Complete to open, after the closure completely of first clutch 33, shift process terminates.Now second clutch 34 is in open mode, i.e., and
Passing power, engine are not delivered on 2 gear driven gears 28 via first clutch 33 for two clutches 34, interior input shaft 19.
The mutual switching of other gears is similar with a gear process that shifts into second, and is no longer described in detail.
Nine gear double-clutch speed changers according to embodiments of the present invention, outside the first output shaft and the second output shaft, also set
The 3rd output shaft has been put, reverse gear driven gear and and the idler gear engaged with 4 gear driven gears is set with the 3rd output shaft
3 gear driven gears of engagement, are fixedly installed 2/4 gear driving gear and 6/8 gear driving gear on outer input shaft, on interior input shaft
1 gear driving gear, 5 gear driving gears, 7/9 gear driving gear are fixedly installed, idler gear keeps off driving gear and 3 with 1 simultaneously
Keep off driven gear engagement.So, 2/4 gear driving gear also assume responsibility for the effect of the existing driving gear that reverses gear, 1 gear driving gear
It also assume responsibility for the effect of existing 3 gear driving gear.The nine gear double-clutch speed changer is realizing nine forward gears and one reverses gear
While, reduce the quantity of the driving gear on inside and outside output shaft, can greatly shorten the entirety of dual-clutch transmission
Length, the vehicle of horizontal forerunner before being applicable to.Also, in overall dimensions identical with common six, seven gear double-clutch speed changers
On the premise of, nine forward gears can be set, so as to increase the gear range of speed changer in the case where overall dimensions are constant,
So that gearratio distribution is more reasonable, and then significantly improve the power performance and class of vehicle.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
All any modification, equivalent and improvement made within refreshing and principle etc., should be included in the scope of the protection.
