Description
Technical field
The invention belongs to transmission for vehicles technical fields, keep off double-clutch speed changer and vehicle more particularly to one kind more.
Background technique
Double disengaging type automatic transmission are that two gearboxes and two clutches are integrated in a transmission case body, two
Root is rotatably sleeved in inside and outside input shaft together and is connected respectively with one of clutch, and two input shafts transmit respectively
The power of two gearbox speed groups completes shift program by automatically switching between two clutches, therefore can be real
The duration of power in existing shift process, i.e., the shortcomings that interrupting power in shift process, overcome AMT shift shock, vehicle
In shift process, the power of engine can shift gears steady rapidly always for delivery to wheel, not only ensure that vehicle plus
Speed, and due to vehicle no longer generate due to shift gears caused by abrupt deceleration situation, also greatly improve vehicle run
Comfort.But since conventional double-clutch automatic transmission is mostly to use double output shaft or single output shaft and use
Driving gear or linear arrangement gear set are shared, therefore its axial dimension is longer, so for preceding transverse engine, front wheel driving
Dynamic such vehicle, especially compact car, since its installation 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 the more difficult work of engine in optimum working zone, thus to the dynamic property and economy of vehicle
Have an adverse effect.
The Chinese patent application of Publication No. CN103711845A discloses one kind and keeps off double-clutch speed changer more comprising:
The outer input shaft and interior input shaft nested together, the interior input shaft are connect by first clutch with power source, described outer
Input shaft is connect by second clutch with power source, and the outer input shaft and interior input shaft are equipped at least one driving tooth
Wheel；In the outer output shaft of first nested together and first in output shaft and the second outer output shaft nested together and second
Output shaft, output shaft is equipped 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 at 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 output is multiple and different
The speed ratio of gear.The engagement between different driving gears and between different driven gears is controlled by switch element, in this way, most
17 forward gears may be implemented more and one reverses gear.
But in CN103711845A, since 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 correspondence gear on outer input shaft, the rotation of the first outer output shaft and the second outer output shaft cannot be straight
The second output gear passed in the first output gear and second in first on output shaft on output shaft is connect, but needs to borrow
The driven gear and driving gear of other gears are helped, in this way, causing in certain gears, by power source (engine or motor) to
The power transfer path of one output gear or the second output gear is too long, causes the transmission efficiency of speed changer to reduce, also, too long
The power transfer path too long reaction time that also will increase shift, influence vehicle operation comfort.
