The hybrid drive train has three kinds of drive patterns：Engine is operated alone, pure motorized motions and engine
With motor combination drive, and can be completed under three kinds of drive patterns power failure-free gear shift action, realize smooth-going gear shift.Under
Face is described in detail for power failure-free gear shift action under three kinds of drive patterns, is specially:
(1) engine acts with the power failure-free gear shift under motor combination drive pattern：
When drive pattern is combination drive pattern, by control synchronizer I 7, synchronizer II 20, assisted clutch 25,
The separation of clutch 17, brake 26 completes power failure-free gear shift action with engaging.Due to two grades to fourth gear, six grades to nine grades
Between lifting shelves it is similar with the power failure-free gear shift process between one grade and two grades, in unpowered between fourth gear and five grades
Disconnected power failure-free gear shift process between gearshift procedure and nine grades and ten grades is similar, and main clutch 2 remains engagement, one grade
Clutch 17 keeps separation during to five grades, and brake 26 remains engaged with, and clutch 17 keeps connecing during six grades to ten grades
Close, brake 26 keep separation, only describe here under combination drive pattern by one grade rise two grades, fourth gear rise five grades, five grades rise six
Shelves, two grades of one grade of drops, five grades of drop fourth gear, the power failure-free gear shifts of six grades of five grades of drops act.It is specific as follows：
(1) one grade rises two grades of power failure-free gear shift actions:
Synchronizer I 7 is moved to middle separation point position by bonding station, while the engagement of assisted clutch 25 is in sliding wear shape
State, engine 1 adjusts square, speed governing jointly with motor 14, when the speed discrepancy of two/seven grades of driving gears 21 and jackshaft II 22 reaches
During the requirement that synchronizer II 20 engages, synchronizer II 20 slides to two/seven grades of driving gears 21, while assisted clutch 25 to the left
Separation, complete one grade and rise two grades of power failure-free gear shift gear shift actions.
(2) fourth gear rises five grades of power failure-free gear shift actions:
Synchronizer II 20 is moved to middle separation point position by bonding station, while assisted clutch 25 starts engagement in cunning
Mill state, engine 1 adjust square, speed governing jointly with motor 14, when the rotating speed of engine 1 and motor 14 and torque meet currently
During driving demand, assisted clutch 25 is completed fourth gear and is risen five grades of power failure-frees by sliding wear status transition to the state that is completely combined
Gear shift gear shift acts.
(3) five grades rise six grades of power failure-free gear shift actions:
Brake 26 is transformed into released state by engagement state, while clutch 17 is transformed into joint shape by released state
State, assisted clutch 25 adjust square, speed governing jointly to sliding wear state, engine 1 by being completely combined State Transferring with motor 14, when
When one/six grade of driving gear 6 reaches the requirement that synchronizer I 7 engages with the speed discrepancy of jackshaft I 9, synchronizer I 7 slides to the left
One/six grade of driving gear 6, while assisted clutch 25 separates, and completes five grades and rises six grades of power failure-free gear shift gear shift actions.
The one grade of power failure-free gear shift action of (4) two grades of drops:
Synchronizer II 20 is moved to middle separation point position by bonding station, while the engagement of assisted clutch 25 is in sliding wear shape
State, engine 1 adjusts square, speed governing jointly with motor 14, when the speed discrepancy of one/six grade of driving gear 6 and jackshaft I 9 reaches same
When walking the requirement that device I 7 engages, synchronizer I 7 slides to one/six grade of driving gear 6 to the left, while assisted clutch 25 separates, and completes
Two grades of drops, one grade of power failure-free gear shift gear shift action.
(5) five grades of drop fourth gear power failure-free gear shift actions:
Assisted clutch 25 is initially separated in sliding wear state, and engine 1 adjusts square, speed governing jointly with motor 14, when four/
When nine grades of driving gears 19 reach the requirement that synchronizer II 20 engages with the speed discrepancy of jackshaft II 22, synchronizer II 20 is slided to the right
To four/nine grades of driving gears 19, while assisted clutch 25 completes five grades of drops four by sliding wear status transition to the state that is kept completely separate
The gear shift action of shelves power failure-free gear shift.
The five grades of power failure-free gear shift actions of (6) six grades of drops:
Synchronizer I 7 is moved to middle separation point position by bonding station, while the engagement of assisted clutch 25 is in sliding wear shape
State, clutch 17 is transformed into released state by engagement state, while brake 26 is transformed into engagement state by released state, starts
Machine 1 adjusts square, speed governing jointly with motor 14, and assisted clutch 25 completes six grades by sliding wear State Transferring to the state that is completely combined
Five grades of power failure-free gear shift gear shift actions of drop.
(2) the power failure-free gear shift action under pattern is operated alone in engine：
It is to lack a power source on the basis of engine and motor combination drive pattern that pattern, which is operated alone, in engine
Motor 14, therefore lack in gearshift procedure tune square, the speed governing of motor 14, but it is synchronizer I 7 in gearshift procedure, synchronous
Device II 20, assisted clutch 25, clutch 17, the separation of brake 26 and joint action and engine and motor combination drive
Gear shift manner of execution under pattern is the same, with reference to above engine and the power failure-free gear shift of motor combination drive pattern are moved
Make, be not repeated to describe herein.
(3) the power failure-free gear shift action under pure electric Drive Mode：
When drive pattern is pure electric Drive Mode, main clutch 2 separates, and assisted clutch 25 separates, synchronizer I 7,
Synchronizer II 20 is located at middle released state, by controlling the separation of clutch 17, brake 26 real with engaging in gearshift procedure
Existing power failure-free gear shift action between one grade and two grades.It is specific as follows：
(1) one grade rises two grades of power failure-free gear shift actions:
Brake 26 is transformed into released state by engagement state, while clutch 17 is transformed into joint shape by released state
State, motor 14 carries out tune square, speed governing in whole transfer process, realizes that power failure-free gear shift acts.
The one grade of process power failure-free gear shift action of (2) two grades of drops：
Clutch 17 is transformed into released state by engagement state, while brake 26 is transformed into joint shape by released state
State, motor 14 carries out tune square, speed governing in whole transfer process, realizes that power failure-free gear shift acts.
Pattern and engine and motor combination drive, which is operated alone, in engine can provide ten drive shifts, engine list
Only drive pattern power source is engine 1, and engine and motor combination drive mode power source are gone back apart from the engines 1
There is the motor 14 between basic transmission output shaft 15 and auxiliary transmission input shaft 16.Therefore, engine, which is operated alone, transmits road
