Clutch C → transmission input shaft E4 → 2-3 gear splined hubs E8 → 2-3 gear combined covers E9 → 3 keep off driving gear E11
The gear driven gear E22 of the axle E21 of → 3 gear driven gear E20 → second → 2 → centre shaft transmission gear F5 → sun wheel shaft driven tooth
Take turns G23；
Reverse gear
1 gear：Clutch C → transmission input shaft E4 → 1 is kept off-the driving gear E5 → reverse gear idle pulley gear J6 → that reverse gear reverse gear
The gear driven gear E22 of the axle E21 of driven gear E23 → 1 is kept off-combined cover E25 → 1 of reversing gear is kept off-splined hub of reversing gear E27 → second → 2
→ centre shaft transmission gear F5 → sun wheel shaft driven gear G23.
Linear motor principle
Power is transferred to sun wheel shaft G22 by sun wheel shaft driven gear G23, and power is then divided into two to be transferred to respectively
Left sun gear G34 and right sun gear G10, wherein, left sun gear G34 drives left lateral star-wheel G29, because left gear ring G39 is diverted
Transmission mechanism locking (both sides gear ring is diverted power locking equal in magnitude, in opposite direction on axle K5), left gear ring G39 can not revolve
Turn, according to Planetary Gear Transmission principle, left planet carrier shaft G45 is driven by left sun gear G34, and power is transferred to left planet carrier shaft
G45, is being transferred to left planet carrier shaft driving gear G43；Similarly, right sun gear G10 drives right planet carrier shaft G1 rotations, and then drives
Right planet carrier shaft driving gear G3 is moved, because when being inputted without steering power, left gear ring G39 is locked out with right gear ring G6, both sides
Power at constant speed is exported, crawler-type harvester straight-line travelling.
Steering power transfer route：Clutch C → transmission input shaft E4 → hydrostatic stepless speed change device input shaft H1
→ hydrostatic stepless speed change device output shaft H2 → hydrostatic stepless speed change device output gear H3 → jackshaft tooth sector F7
→ steering spindle driven gear K6, then power be divided into two,
1 tunnel：Steering spindle left side gear K4 → left gear ring G39 → left planet carrier shaft G45 → left planet carrier shaft driving gear
G43；
2 tunnels：Steering spindle right side gear K10 → right turn idle pulley gear K16 → right gear ring G6 → right planet carrier shaft G1 → left side
Planet carrier shaft driving gear G3.
Ratio steering principle
As described in steering power transfer route, it is the steering spindle left side gear K4 left gear ring G39 of driving that left side, which is turned to, and right side
Steering is steering spindle right side gear K10 driving right turn idle pulley gear K16, then drives right gear ring G6 to turn to, hydrostatic stepless
Speed change gear H is rotated forward, and hydrostatic stepless speed change device output gear H3 driving jackshaft tooth sectors F7 is rotated, jackshaft
Tooth sector F7 driving jackshafts F4 is rotated, and jackshaft F4 driving steering spindle driven gears K6 is rotated, steering spindle driven gear K6
Steering spindle K5 is driven to rotate, steering spindle K5 driving steering spindle left side gear K4 and steering spindle right side gear K10 are rotated, and steering spindle is left
Side gear K4 drives left gear ring G39 to rotate, and steering spindle right side gear K10 driving right turn idle pulley gears K16 is rotated, and right turn is lazy
Wheel gear K16 drives right gear ring G6 to rotate；Because steering spindle left side gear K4 drives left gear ring G39 to rotate, and on the right side of steering spindle
Gear K10 drives right gear ring G6 to rotate by right turn idle pulley gear K16 so that left and right sides gear ring constant speed opposite direction rotates,
Both sides gear ring is diverted mechanism locking during straight-line travelling, due to hydrostatic stepless speed change device H drivings, destroys both sides gear ring
Dynamic balance, both sides gear ring constant speed in the presence of hydrostatic stepless speed change device H is reversely rotated, in this rotary speed and sun gear
After input speed synthesis so that left planet carrier shaft G45 and right planet carrier shaft G1 exports unequal rotating speed, so as to promote driving wheel two
End output different rotating speeds, and then realize and turned to side；Similarly, when hydrostatic stepless speed change device H is rotated backward, crawler belt dress
It is standby to be turned to opposite side；The angular speed and hydrostatic stepless speed change device H output speed proportion relations of output are turned to, it is quiet
Hydraulic variable speed unit H can be operated by steering wheel or steering linkage, therefore, and the angular speed for turning to output can be with turning to driver
Structure K proportion relations, so as to realize accurately ratio steering.
