Than the characteristic parameter of the corresponding first planet row P1 of K1, K2 corresponds to the characteristic parameter of the second planet row P2, and K3 corresponds to third planet row
The characteristic parameter of P3, table 1 are each shelves binding member state table for representing three planet rows, four sections of hydraulic machinery infinitely variable transmissions.Wherein
√ represents binding member and is in bonding state.
Each shelves binding member state table of table 1, three planet rows, four sections of hydraulic machinery infinitely variable transmissions
As Figure 2-Figure 5, the specific route of gearbox is as follows:
When first clutch K1 is combined, three planet rows are worked at the same time, and engine is defeated via the progress power of entering spindle 28
Enter, change input speed via the first fixed tooth wheel set i120 and drive variable pump, is adjusted by regulated variable pump output flow
The revolving speed of fixed displacement motor, the revolving speed of fixed displacement motor by the second fixed tooth wheel set i221 pass to first row sun gear 2 carry out it is hydraulic
Power input, while engine also drives first row gear ring 5 to carry out machine power input through entering spindle 28, hydraulic and machinery is dynamic
Power is converged by the first planet row via 3 power output of first row planet carrier；Because first row planet carrier 3, second row gear ring 9,
Third seniority among brothers and sisters carrier 10 and the 5th fixed tooth wheel set i51 are integrated rigid structure, therefore the output rotation of first row planet carrier 3 is same
When also drive second row gear ring 9, third seniority among brothers and sisters carrier 10 and the 5th fixed tooth wheel set i51 output rotation；Other first planet row
Gear ring 5 and second row planet carrier 6 are rigid unitary structure, therefore also drive the second rows of planetary while the rotation of first row gear ring 5
Frame 6 rotates together.9 power of second row gear ring input with 6 power of second row planet carrier input by the second planet row confluence via
The output rotation of secondary sun gear 7, because secondary sun gear 7 and third row's sun gear 13 are duplicate gear, second row
Sun gear 7 also drives third row's sun gear 13 to rotate while rotation, third arranges the input of 13 power of sun gear and third rows of planetary
The input of 10 power of frame is by third planet row's confluence via third planet toothrow circle 11) carry out power output, third planet toothrow
11) circle is connected by first clutch K1 with third fixed tooth wheel set i314, it is defeated finally to carry out power by third fixed tooth wheel set i314
Out.Realize first grade.Then advance Reversing Clutch KV, KR are transmitted power to via jackshaft 27, passes through point of control KV, KR
It is not implemented in combination with advance or backward gear.A biggish transmission ratio can be obtained when first segment, meet the quiet of tractor
Starting is carried, the power of engine is enable to maximize use.
When second clutch K2 is combined, the work of the first and second planet rows, third planet row is in idle running without dynamic
Power input and output, engine carry out power input via entering spindle 28, change input speed via the first fixed tooth wheel set i120
And variable pump is driven, by regulated variable pump output flow come the revolving speed of adjustment quantitative motor, the revolving speed of fixed displacement motor passes through the
Two fixed tooth wheel set i221 pass to first row sun gear 2 and carry out hydraulic power input, while engine is through entering spindle 28 also band
Dynamic first row gear ring 5 carries out machine power input, and hydraulic and machine power is converged by the first planet row via the first rows of planetary
3 power output of frame；Because first row planet carrier 3, second row gear ring 9, third seniority among brothers and sisters carrier 10 and the 5th fixed tooth wheel set i51 are
Unitary rigid structure, therefore second row gear ring 9, third seniority among brothers and sisters carrier 10 are also driven while the output rotation of first row planet carrier 3
And the 5th fixed tooth wheel set i51 output rotation；Other first planet toothrow circle 5 is rigid unitary structure with second row planet carrier 6,
Therefore second row planet carrier 6 is also driven to rotate together while first row gear ring 5 rotates.9 power of second row gear ring input and the
The input of 6 power of two-row planetary frame is exported via secondary sun gear 7 by the second planet row confluence and is rotated, because of the second row sun
Wheel 7 is duplicate gear with third row's sun gear 13, so secondary sun gear 7 also drives third to arrange sun gear 13 while rotation
Rotation carries out power output, and secondary sun gear 7 and third row's sun gear 13 pass through second clutch K2 and the 4th fixed tooth wheel set
I415 connection finally carries out power output by the 4th fixed tooth wheel set i415.Realize second gear.Then it is transmitted via jackshaft 27 dynamic
Power is to advance Reversing Clutch KV, KR, by control KV, KR respectively in connection with realization advance or backward gear.
When clutch K3 is combined, the first planet row work, the second third planet row is inputted in idle running without power
Output, engine carry out power input via entering spindle 28, change input speed via the first fixed tooth wheel set i120 and drive
Variable pump, by regulated variable pump output flow come the revolving speed of adjustment quantitative motor, the revolving speed of fixed displacement motor passes through the second fixed tooth
Wheel set i221 passes to first row sun gear 2 and carries out hydraulic power input, while engine also drives first through entering spindle 28
Toothrow circle 5 carries out machine power input, and hydraulic and machine power is converged by the first planet row via 3 power of first row planet carrier
Output；Simultaneously first row planet carrier 3 and the 5th fixed tooth wheel set i51 be structure as a whole, at this time the 5th fixed tooth wheel set i51 pass through K3 from
Clutch, which combines, carries out power output.Realize third gear.Then via jackshaft 27 transmit power to advance Reversing Clutch KV,
KR, by control KV, KR respectively in connection with realization advance or backward gear.
When clutch K4 is combined, the work of the first and second planet rows, it is defeated without power that third planet row is in idle running
Enter output, engine carries out power input via entering spindle 28, changes input speed and band via the first fixed tooth wheel set i120
Dynamic variable pump, by regulated variable pump output flow come the revolving speed of adjustment quantitative motor, the revolving speed of fixed displacement motor is fixed by second
Gear pair i221 passes to first row sun gear 2 and carries out hydraulic power input, while engine also drives the through entering spindle 28
One toothrow circle 5 carries out machine power input, and hydraulic and machine power is converged dynamic via first row planet carrier 3 by the first planet row
Power output；Because first row planet carrier 3, second row gear ring 9, third seniority among brothers and sisters carrier 10 and the 5th fixed tooth wheel set i51 are integrated
Rigid structure, thus first row planet carrier 3 output rotation while also drive second row gear ring 9, third seniority among brothers and sisters carrier 10 and
5th fixed tooth wheel set i51 output rotation；Other first planet toothrow circle 5 is rigid unitary structure with second row planet carrier 6, therefore
First row gear ring 5 also drives second row planet carrier 6 to rotate together while rotation.The input of 9 power of second row gear ring and second row
The input of 6 power of planet carrier is exported via secondary sun gear 7 by the second planet row confluence and is rotated, because of secondary sun gear 7
It is duplicate gear with third row's sun gear 13, so secondary sun gear 7 also drives third to arrange 13 turns of sun gear while rotation
Dynamic to carry out power output, secondary sun gear 7 and third row's sun gear 13 are connected by second clutch K2 and i6 fixed tooth wheel set 16
It connects, power output is finally carried out by i6 fixed tooth wheel set 16.Realize fourth speed.Then advance is transmitted power to via jackshaft 27 to fall
Clutch KV, KR is recessed, by control KV, KR respectively in connection with realization advance or backward gear.
