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, farm machinery straight-line travelling.
