The purpose of this utility model is achieved through the following technical solutions:
Three-shaft wheeled tractor hoist steering hydraulic device operating principle: at first, calculate parameter and the size of determining front and back steering mechanism by theory, turn to the parameter and the allocation proportion that turns to the hydraulic fluid flow rate that turns to oil cylinder around the time of oil cylinder before and after determining according to the requirement of front and back steering mechanism then, and then the proportion expression flow divider-combiner used of definite steering mechanism, steering mechanism's coordinate synchronization before and after guaranteeing.The differential requirement that left and right sidesing driving wheel rotates during the second consideration Vehicular turn.Make two hand-operated direction valves be in walking position during vehicle to run, steering wheel rotation when turning to, the pressure oil of hydraulic oil pump are leaded up to Monostable valve, steering gear, proportion expression flow divider-combiner and are turned to oil cylinder to front and back, finish the go to action of front and back wheel; Another road is separated oil cylinder with two pilot operated directional control valves to corresponding steering cluth through choke valve, reducing valve simultaneously, and steering cluth separates cylinder action, partially opens corresponding steering cluth, the differential requirement of left and right sidesing driving wheel when realizing turning to.The hydraulic oil oil return of two-way all is back to hydraulic oil container.The working connection pressure of steering hydraulic device is limited by safety valve, and steering cluth separates the operating pressure of oil cylinder to be controlled by reducing valve, and the aperture control of regulating choke valve enters the flow that steering cluth separates oil cylinder, makes Vehicular turn smooth-going.
Three-shaft wheeled tractor hoist steering hydraulic device is by two hand-operated direction valves, after turn to oil cylinder, before turn to oil cylinder, the proportion expression flow divider-combiner, pilot operated directional control valve, all-hydraulic steering gear, Monostable valve, reducing valve, choke valve, steering cluth separates oil cylinder, safety valve, oil pump, strainer, fuel tank is formed, the inlet port of oil pump is connected with fuel tank by pipeline, the oil-out of oil pump is connected with the hand-operated direction valve oil-in by pipeline, the oil-out of hand-operated direction valve is connected with choke valve with Monostable valve respectively by pipeline, the oil-out one tunnel of Monostable valve is connected by pipeline with all-hydraulic steering gear, the oil return opening of Monostable valve directly is connected with fuel tank by pipeline with the oil return opening of hand-operated direction valve, two oil-out each minute two-way of all-hydraulic steering gear: the one tunnel mouthful is connected with the control of pilot operated directional control valve, and one the tunnel turns to oil cylinder to be connected by pipeline with proportion expression flow divider-combiner and front and back; The oil-in of a pilot operated directional control valve is connected with the oil-out of Monostable valve, and the oil-out of this pilot operated directional control valve is connected with another pilot operated directional control valve control mouth.The choke valve oil-out is connected with the oil-in of reducing valve by pipeline, the oil-out of reducing valve is connected with the oil-in of another pilot operated directional control valve by pipeline, the oil-out of this pilot operated directional control valve separates oil cylinder by pipeline and steering cluth and is connected, the oil return opening of two pilot operated directional control valves and all-hydraulic steering gear is connected by pipeline with strainer, strainer places in the fuel tank, safety valve is connected with the oil-out of oil pump by pipeline, and the drain tap of safety valve is connected with fuel tank by pipeline.See Fig. 1 and Fig. 2 for details.
Benefit of the present utility model is: this apparatus structure is reasonable, and is easy to operate, during vehicle ', the front and back vehicle bridge turns to, and left and right sidesing driving wheel is realized differential, makes the Vehicular turn radius little, reduced the tyre skidding when turning to, raising turns to the safety of travelling, and prolongs the application life of tire
