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
Output shaft is equipped with least one driven gear being engaged 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 fast 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 to control between different driving gears 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 to reduce, also, long
The power transfer path oversize reaction time that can also increase gearshift, influence vehicle operation comfortableness.

Eight gear driven gears 19.Second outer output shaft is transferred torque to by the engagement of the eight gear synchronizers 20 of driven gear 19 and the 5th
The 6th synchronizer 25 on 18, then the engagement by the 6th synchronizer 25 and seven gear driven gears 27, are transferred torque to outer defeated
Enter seven/nine gear driving gears 32 on axle 28, seven/nine gear driving gears 32 transfer torque to nine gear driven gears 3;Pass through nine
The engagement of the synchronizer 4 of driven gear 3 and first is kept off, transfers torque to the first final gear 2 on output shaft 1 in first,
Again by differential mechanism gear ring 24, and power is finally exported by differential mechanism 23.
Power transmission of reversing gear route:
First, the 3rd synchronizer 8 and two gear driven gears 7 engage;Second synchronizer 6 engages with the driving gear 5 that reverses gear;The
Four synchronizers 16 and the second outer output shaft 18 engage;6th synchronizer 25 and three gear driven gears 22 engage, other synchronizers point
From.Second clutch 30 closes, and engine torque passes to the two gear driving gear of interior input shaft 14 by second clutch 30
13, pass to two gear driven gears 7 via two gear driving gear 13.Will by the engagement of two gear driven gears 7 and the 3rd synchronizer 8
Moment of torsion is delivered to the second synchronizer 6 on the first outer output shaft 10, then connecing by the second synchronizer 6 and the driving gear 5 that reverses gear
Close, three gear driven gears 22 are transferred torque to by the driving gear 5 that reverses gear;Pass through the three gear synchronizers 25 of driven gear 22 and the 6th
Engagement, transfer torque on the second outer output shaft 18, then the engagement by the second outer synchronizer 16 of output shaft 18 and the 4th,
The second final gear 26 on output shaft 17 in second is transferred torque to, then by differential mechanism gear ring 24, and finally by difference
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.Meanwhile seven keep off and the shared driving gear of nine gears (i.e. seven/nine gear masters
Moving gear), six gears share a driving gear (i.e. six/eight gear driving gears) with eight gears, can effectively shorten the axle of speed changer
To length, it is 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 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.
