Gearshift principle：
1 gear
Clutch C → transmission input shaft E4 → 1 is kept off-reverses gear driving gear E5, and → 1 gear driven gear E28 → 1 is kept off-reverses gear
Combined cover E25 → 1 keeps off-reversed gear the gear driven gear E22 of the axle E21 of splined hub E27 → second → 2 → 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
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), left gear ring G39 can not rotate,
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,
It 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, because when being inputted without steering power, left gear ring G39 is locked out with right gear ring G6, both sides power
Equispeed output, farm machinery straight-line travelling.
