STEERING GEAR OF SELF-PROPELLED MACHINE Russian patent published in 2007 - IPC B62D11/24 B62D55/02 

FIELD: transport engineering.

SUBSTANCE: invention can be used in tractors, self-propelled vehicles half-track prime mover and carriers. Proposed self-propelled vehicle with combination propulsor has engine coupled through gearbox and transfer case with wheel and track propulsor and steering gear providing opposite turning of steerable wheels by means of systems of tie-rods and levers. Drive of track propulsor is furnished additionally with position displacement steering mechanism including adjustable hydraulic pump, hydraulic motor coupled with sun gears of left-hand and right-hand summing planetary gear trains. Device to control delivery of hydraulic pump is mechanically coupled with tie-rod of steering device of steerable wheels. Invention improves steerability of vehicle with combination propulsors owing to combined realization of wheel and track turning schemes, reduces power losses at simultaneous operation of wheel and track propulsors in turning and increases accuracy of steering control owing to involvement of track propulsor into process of formation of turning forces.

EFFECT: improved steerability of vehicle.
