The operation principle of each operating mode is as follows：
When input shaft synchronizer 120 is closed, the first input shaft 11 and the second input shaft 21 establish be connected by power.
When first axle wheel synchronizer 101 is closed, the first clutch transmission unit and the first jackshaft 31 establish be connected by power,
Power on first input shaft 11 is transferred to the first jackshaft 31 by the first clutch transmission unit.
When the second axis wheel synchronizer 102 is closed, the second clutch transmission unit and the first jackshaft 31 establish be connected by power,
Power on second input shaft 21 is transferred to the first jackshaft 31 by the second clutch transmission unit.
When third axis wheel synchronizer 103 is closed, third clutch transmission unit and the first jackshaft 31 establish be connected by power,
Power on first input shaft 11 is transferred to the first jackshaft 31 by third clutch transmission unit.
When the 4th axis wheel synchronizer 104 is closed, the 4th clutch transmission unit and the first jackshaft 31 establish be connected by power,
Power on second input shaft 21 is transferred to the first jackshaft 31 by the 4th clutch transmission unit.
When the 5th axis wheel synchronizer 105 is closed, the 5th clutch transmission unit and the first jackshaft 31 establish be connected by power,
Power on first jackshaft 31 is transferred to output shaft 51 by the 5th clutch transmission unit.
When the 6th axis wheel synchronizer 106 is closed, the 6th clutch transmission unit and the first jackshaft 31 establish be connected by power,
Power on first jackshaft 31 is transferred to output shaft 51 by the 6th clutch transmission unit.
When the 7th axis wheel synchronizer 107 is closed, the 7th clutch transmission unit and the second jackshaft 41 establish be connected by power,
First input shaft 11 establishes be connected by power by the 7th clutch transmission unit and the second jackshaft 41.
Since the second countershaft-gear 45 is often engaged with the 6th driven gear or the 5th driven gear, the second jackshaft
By the second countershaft-gear 45, there are be connected by powers with output shaft 51 always, and when the 7th axis wheel synchronizer 107 is closed, first is defeated
Enter axis 11 and power is transferred to by output shaft 51 by the 7th clutch transmission unit and the second jackshaft 41.
For second driving motor 20 not under operating mode, the first driving motor 10 can pass through input shaft synchronizer 120, first
Clutch transmission unit, the second clutch transmission unit, third clutch transmission unit, the 4th clutch transmission unit output power to
One jackshaft 31, and output shaft 51 is outputted power to by the 5th clutch transmission unit or the 6th clutch transmission unit, finally
Power is exported by output shaft 51.
Since the second jackshaft 41 establishes be connected by power by the second countershaft-gear 45 with output shaft 51, in the mould
Under formula, the first driving motor 10 can export power by the axial output shaft in the second centre, you can to pass through the 7th clutch transmission
Unit outputs power to the second jackshaft 41, and outputs power to output shaft 51 by the second countershaft-gear 45, finally
Power is exported by output shaft 51.
For first driving motor 10 not under operating mode, the second driving motor 20 can pass through input shaft synchronizer 120, first
Clutch transmission unit, the second clutch transmission unit, third clutch transmission unit, the 4th clutch transmission unit output power to
One jackshaft 31, and output shaft 51 is outputted power to by the 5th clutch transmission unit or the 6th clutch transmission unit, finally
Power is exported by output shaft 51.
Since the second jackshaft 41 establishes be connected by power by the second countershaft-gear 45 with output shaft 51, in the mould
Under formula, the second driving motor 20 can export power by the axial output shaft in the second centre, you can to pass through input shaft synchronizer
120, the 7th clutch transmission unit outputs power to the second jackshaft 41, and is outputed power by the second countershaft-gear 45
To output shaft 51, power is finally exported by output shaft 51.
Under the equal operating mode of first, second driving motor, the first driving motor 10 and the second driving motor 20 can pass through
Input shaft synchronizer 120 carries out power coupling, therefore in this mode, the first driving motor 10 and the second driving motor 20 it is dynamic
Power is coupled in the first input shaft or the second input shaft, then passes through the first clutch transmission unit, the second clutch transmission unit, third
Clutch transmission unit, the 4th clutch transmission unit output power to the first jackshaft 31, and pass through the 5th clutch transmission unit
Or the 6th clutch transmission unit output power to output shaft 51, finally by output shaft 51 export power.
Since driving motor 10 and the second driving motor 20 can export power to the first jackshaft 31 respectively, at this
Under pattern, input shaft synchronizer 120 disconnects, and the first driving motor 10 passes through the first clutch transmission unit or third clutch transmission list
Member outputs power to the first jackshaft 31, and the second driving motor 20 passes through the second clutch transmission unit or the 4th clutch transmission list
Member outputs power to the first jackshaft 31, the power of the first jackshaft 31 coupling driving motor 10 and the second driving motor 20
Afterwards, output shaft 51 is outputted power to by the 5th clutch transmission unit or the 6th clutch transmission unit, finally by output shaft 51
Export power.
Since the second jackshaft 41 establishes be connected by power by the second countershaft-gear 45 with output shaft 51, in the mould
Under formula, the first driving motor 10 can export power by the axial output shaft in the second centre, you can to pass through the 7th clutch transmission
Unit outputs power to the second jackshaft 41, and outputs power to output shaft 51 by the second countershaft-gear 45, and second
Driving motor 20 outputs power to the first jackshaft 31 by the second clutch transmission unit or the 4th clutch transmission unit, and first
Jackshaft 31 outputs power to output shaft 51 by the 5th clutch transmission unit or the 6th clutch transmission unit, in output shaft 51
Locate the power of coupling driving motor 10 and the second driving motor 20, power is finally exported by output shaft 51.
During shift, since the power output of the first driving motor 10 and the second driving motor 20 is not same
On input shaft, thus when the power of the first driving motor 10 and the second driving motor 20 by the first jackshaft 31 to output shaft 51
When exporting power, when a power source interrupts power output, can power be exported by another power source so that vehicle moves
Power output will not be interrupted in shift process；Particularly, when the power of the first jackshaft is from the 5th clutch transmission unit to output
Axis 51 export powershift arrive from the 6th clutch transmission unit to output shaft 51 output power during, due to the first jackshaft
Be connected by power can be interrupted between 31 and output shaft 51, therefore another power source can be by the second jackshaft 41 to output shaft 51
Export power, it is ensured that the power output of vehicle will not interrupt in shift process；Equally, the first driving motor 10 and second drives
When the power of motor 20 exports power by the second jackshaft 41 to output shaft 51, when a power source interrupts power output,
Can power can be exported to output shaft 51 by the first jackshaft 31 from another power source so that the power output of vehicle exists
It will not be interrupted in shift process.
