TRACTOR STEERING DEVICE Russian patent published in 1994 - IPC

FIELD: tractor-building industry. SUBSTANCE: steering gear is connected by rocker arm with valves of bypass directional valve. Said valves are used as a control mechanism. As liquid pressure drops in clutches of one side of tractor, said pressure must be raised proportionately to torque. The energy flows to caterpillar tracks are adjusted to suit the course and the reaction of soil. Device comprises steering wheel with rocker arm connecting it to bypass valves of hydraulic system control. Turning of the steering wheel makes the valves of bypass directional valve to reduce pressure in steering clutches of lagging track and to raise it in steering clutches of leading track thus adjusting pressure and power consumption to suit the torque transmitted to tracks. EFFECT: improved design. 3 dwg
