METHOD OF TURNING BY PROPULSORS AND TRACTOR STEERING DEVICE Russian patent published in 2011 - IPC B62D11/18 

FIELD: transport.

SUBSTANCE: invention relates to automotive industry. Engine crankshaft 1 engages with pump 4 and gearbox 5 actuating right and left propulsor rpm control mechanism 11 incorporating two reduction gears 12 (right and left). Left (right) pinion frame 16 of reduction gear 12 rigidly engages with left (right) shaft 16, pinion frame planet pinions engage with left (right) annular ring and, hence, left (right) gear 18. Said gears are engaged via left and right gears 19 and with gear 20 articulated with engine 21. Engine channels 22, 23 communicate with pump 4 via lock 24. Steering wheel 6 is coupled with proportioning pump shaft 7. Control channels of pump 7 communicate via two-position control valve 9 with pump 7. Left (right) coupling 25 engaged with left (right) universal joint 27 engaged with left (right) propulsor 29 is fitted on extension of left (right) shaft. Shaft of engine 21 is coupled with reduction high-speed shaft, while reduction gear low-speed shaft is coupled with gear 20 of left and right propulsor rpm control mechanism 11. Spool of hydraulic control valve 9 is coupled with gearbox reverse gear yoke slide.

EFFECT: higher maneuverability and simplified control.
