Gearshift principle：
1 gear
Clutch C → transmission input shaft E4 → 1 keeps off-reverses gear driving gear E5 → 1 gear driven gear E28 → 1 and keeps off-reverse gear
Combined cover E25 → 1 keeps off-reverses gear splined hub E27 → the second axle E21 → 2 gears driven gear E22 → centre shaft transmission gear F5 → too
Positive wheel shaft driven gear G23；
2 gears
Clutch C → transmission input shaft E4 → 2-3 gear splined hubs E8 → 2-3 gear combined covers E9 → 2 keep off driving gear E7
→ 2 gear driven gear E22 → centre shaft transmission gear F5 → sun wheel shaft driven gear G23；
3 gears
Clutch C → transmission input shaft E4 → 2-3 gear splined hubs E8 → 2-3 gear combined covers E9 → 3 keep off driving gear E11
→ 3 gear driven gear E20 → the second axle E21 → 2 keep off driven gear E22 → centre shaft transmission gear F5 → sun wheel shaft driven tooth
Wheel G23；
Reverse gear
1 gear：Clutch C → transmission input shaft E4 → 1 keeps off-reverses gear the driving gear E5 → idle pulley gear J6 that reverses gear → reverse gear
Driven gear E23 → 1 keeps off-reverses gear combined cover E25 → 1 and keeps off-reverse gear splined hub E27 → the second axle E21 → 2 gears driven gear E22
→ middle 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 and is 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 on axle K5, in opposite direction), 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 input into 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 turns to, and right side
Steering is that steering spindle right side gear K10 drives 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 drives jackshaft tooth sector F7 to rotate, jackshaft
Tooth sector F7 drives jackshaft F4 to rotate, and jackshaft F4 drives steering spindle driven gear K6 to rotate, steering spindle driven gear K6
Steering spindle K5 is driven to rotate, steering spindle K5 drives steering spindle left side gear K4 and steering spindle right side gear K10 to rotate, and steering spindle is left
Side gear K4 drives left gear ring G39 to rotate, and steering spindle right side gear K10 drives right turn idle pulley gear K16 to rotate, 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 steering spindle right side
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 rotation,
Both sides gear ring is diverted mechanism's locking during straight-line travelling, because hydrostatic stepless speed change device H drives, 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 being 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, the angular speed for turning to output can be with steering driver
Structure K proportion relations, so as to realize that accurately ratio is turned to.
