Description
Technical field
The invention belongs to transmission for vehicles technical field, more particularly to a kind of many gear double-clutch speed changers and vehicle.
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 are transmitted respectively
The power of two gearbox speed groups, by automatically switching between two clutches so as to complete gearshift program, therefore can be real
The continuation of power, i.e., interrupt power in shift process, overcome the shortcoming of AMT shift shocks, car in existing shift process
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 is no longer produced due to abrupt deceleration situation caused by gearshift, also greatly improve vehicle operation
Comfortableness.But, because conventional double-clutch automatic transmission is generally using 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, above-mentioned speed changer is just more difficult to be used, 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 of vehicle
Have a negative impact.
Publication No. CN103711845A Chinese patent application discloses and keeps off double-clutch speed changer one kind more, and it includes：
The outer input shaft and interior input shaft nested together, the interior input shaft is 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 output shaft in the first output gear engaged with differential gear, described second and set in described first
Have the second output gear engaged with differential gear, the first outer output shaft, output shaft in first, the second outer output shaft and
Output shaft is equipped with the driven gear of at least one engagement corresponding with the driving gear in second；Switch element, the switch
Element can control the engagement between different driving gears and between different driven gears, so that speed changer exports multiple differences
The speed ratio of gear.Engagement between different driving gears and between different driven gears is controlled by switch element, so, most
It can realize 17 forward gears more and one reverses gear.
But, in CN103711845A, because the first output gear and the second output gear are to be connected to first
In interior output shaft and second on output shaft, and switch element is only between the different driving gears of control and different driven tooths
Engagement between wheel, thus, the driven gear of the first outer output shaft and certain gear on the second outer output shaft and interior input shaft or
After the driving gear engagement of corresponding gear on outer input shaft, the rotation of the first outer output shaft and the second outer output shaft can not be straight
Connect and pass to the second output gear in the first output gear and second in first on output shaft on output shaft, but need to borrow
The driven gear and driving gear of other gears are helped, so, is caused in some gears, by power source (engine or motor) to
The power transfer path of one output gear or the second output gear is oversize, causes the transmission efficiency of speed changer and reduces, also, long
Power transfer path it is oversize can also increase the reaction time of gearshift, the comfortableness of influence vehicle operation.

Ten gear double-clutch speed changers described above, in the case where mechanical structure is constant, remove the controlling stream of ten gears
Journey, can access nine gear double-clutch speed changers.
Many 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 gears and its residing axle
It is defeated in the combination of output shaft and separation and the second outer output shaft and second with separation, in the first outer output shaft and first
The combination and separation of shaft, to realize phase on the speed changing function of the nine gear above, also, the first outer output shaft and the second outer output shaft
Answer after 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
Need not by other gears driven gear and driving gear, so, shorten by power source (engine or motor) to
The power transfer path of one final gear or the second final gear, improves the transmission efficiency of speed changer, reduces gearshift
Reaction time, improve vehicle operation comfortableness.Meanwhile, six gears share a driving gear with eight gears, and (i.e. six/eight gears are led
Moving gear), it can effectively shorten the axial length of speed changer, be easy to arrangement of the speed changer in front deck.
In addition, one embodiment of the invention additionally provides a kind of vehicle, it includes above-mentioned many 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
Any modifications, equivalent substitutions and improvements made within refreshing and principle etc., should be included in the scope of the protection.
