Wheel TD29 is rotated, and right turn idle pulley gear TD29 drives right gear ring TR23 to rotate；Because left steering gear TD27 drives left gear ring
TL23 is rotated, and right turn gear TD28 drives right gear ring TR23 to rotate by right turn idle pulley gear TD29 so that left and right two
Gear ring constant speed in side is reversely rotated, during straight-line travelling left and right sides gear ring by ratio steering mechanism locking, due to hydrostatic stepless change
Fast mechanism H drives, and destroys the dynamic balance of left and right sides gear ring, and both sides gear ring is in the presence of hydrostatic stepless speed changing mechanism H
Constant speed is reversely rotated, after this rotary speed and the synthesis of sun gear input speed so that left planet carrier shaft TL12 and right lateral star
Frame axle TR12 exports unequal rotating speed, so as to promote driving wheel two ends to export different rotating speeds, and then realizes being turned to side, together
Reason, when hydrostatic stepless speed changing mechanism H is rotated backward, crawler equipment to opposite side is turned to；Turn to output angular speed with it is quiet
Hydraulic stepless speed changing machine structure H output speed proportion relations, hydrostatic stepless speed changing mechanism H can be drawn by steering wheel or steering
Bar is operated, therefore turns to the angular speed and hydrostatic stepless speed changing mechanism H speed governing amplitude proportion relation of output, so as to realize
Precisely ratio is turned to.
