Description
Technical field
The invention belongs to transmission for vehicles technical field, and double-clutch speed changer and vehicle are kept off more particularly to one kind more.
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 transmit respectively
The power of two gearbox speed groups, by automatically switching between two clutches so as to complete program of shifting gears, therefore can be real
The continuation of power, i.e., interrupt power in shift process in existing shift process, the shortcomings that overcoming AMT shift shocks, car
In shift process, the power of engine can be shifted gears rapid steady for delivery to wheel all the time, not only ensure that vehicle plus
Speed, and because vehicle no longer produces the situation that is a significant slowdown caused by gearshift, also greatly improve vehicle operation
Comfortableness.But because the double-clutch automatic transmission of routine is mostly to use double output shaft or single output shaft 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.
Publication No. CN103711845A Chinese patent application discloses one kind and keeps off double-clutch speed changer more, and it includes：
The outer input shaft and interior input shaft nested together, the interior input shaft are connected by first clutch with power source, described outer
Input shaft is connected by second clutch with power source, and the outer input shaft and interior input shaft are equipped with least one driving tooth
Wheel；In the first outer output shaft nested together and first in output shaft and the second outer output shaft nested together and second
Output shaft, output shaft is provided with the first output gear engaged with differential gear in described first, and output shaft is set in described second
Have the second output gear engaged with differential gear, the first outer output shaft, output shaft in first, the second outer output shaft and

Fast device 23 exports power.
Ten gear double-clutch speed changers described above, in the case where mechanical structure is constant, remove the controlling stream of ten gears
Journey, nine gear double-clutch speed changers can be accessed.
More gear double-clutch speed changers according to the above embodiment of the present invention, are provided with two gears, three gears, four gears, six gears, seven
Gear, eight gears and nine keep off this seven groups of principals and subordinates and move shift gear, and sychronisation controls the combination of all driven gear and its residing axle
With separation, it is defeated in the combination of output shaft and separation and the second outer output shaft and second in the first outer output shaft and first
The combination and separation of shaft, to realize the speed changing function of the nine gear above, also, phase on the first outer output shaft and the second outer output shaft
After answering the driven gear of gear and the driving gear engagement of the corresponding gear on interior input shaft or outer input shaft, pass through synchronous dress
The combination of output shaft in output shaft or the second outer output shaft and second in control the first outer output shaft and first is put, will can be moved
Power is directly passed in first the second final gear on output shaft in the first final gear or second on output shaft, and
So, it need not be shortened by the driven gear and driving gear of other gears by power source (engine or motor) to
The power transfer path of one final gear or the second final gear, the transmission efficiency of speed changer is improved, reduce gearshift
Reaction time, improve vehicle operation comfortableness.
In addition, one embodiment of the invention additionally provides a kind of vehicle, it includes above-mentioned more gear double-clutch speed changers.
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.
