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

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, in opposite direction), 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 input into without steering power, left gear ring G39 is locked out with right gear ring G6, both sides power
Equispeed output, crawler type talents for agri-mechanization straight-line travelling.
