Abstract
The utility model relates to an agricultural tractor, in particular relates to a hydraulic direction power-assisting device for an articulated steering tractor, comprising an oil tank 1, a hydraulic gear pump 2, a steering valve, oil cylinders (4-1, 4-2) and an oil pipe 5. The hydraulic direction power-assisting device is characterized in that two single-piston oil cylinders are adopted as the oil cylinders 4; the support points of the oil cylinders are arranged on the left and right sides of an engine and the trailer articulated rotary point. The hydraulic direction power-assisting device has the beneficial effects that the hydraulic direction power-assisting device has small volume, compact structure, low manufacturing cost, reliable and stable operation, reasonable layout, and is convenient and flexible in operating the steering wheel.
Description
Technical field
The utility model relates to a kind of farm tractor, relates to a kind of hydraulic directio work-saving device that is used for the articulated steering trac. specifically.
Background technology
Disclosed in the market articulated steering trac., most of worm gearing that adopts turns to complex structure, layout is unreasonable, and piece volumes is excessive, and the mechanical power transmission is dumb, safety factor is poor, and transmission link is many, and the bearing circle operation is overweight and manufacturing cost is high.
The utility model content
The purpose of this utility model provides a kind of simple in structure, and low cost of manufacture is rationally distributed, bearing circle operation light and flexible, reliable and stable work and be used for the hydraulic directio work-saving device of articulated steering trac..
In order to achieve the above object, the technical solution of the utility model is achieved like this: a kind of hydraulic directio work-saving device that is used for the articulated steering trac. comprises fuel tank 1, hydraulic gear pump 2, convertible valve 3, oil cylinder (4-1; 4-2), oil pipe 5 is characterized in that: described oil cylinder 4 adopts two and singly goes out the formula oil cylinder, and its strong point is arranged on the engine and the trailer handing-over pivot point left and right sides.
Described convertible valve 3 is set together with steering wheel shaft.
The utility model beneficial effect is:
It is little to the utlity model has volume, compact conformation, and low cost of manufacture, reliable and stable work, rationally distributed, bearing circle operation light and flexible.
Description of drawings:
Fig. 1 is the utility model side integral structure scheme drawing, also can be used as Figure of abstract
Fig. 2 is the birds-eye view of Fig. 1
Wherein: 1, be fuel tank
2, be hydraulic gear pump
3, be convertible valve
4-1, be left oil cylinder
4-2, be right oil cylinder
5, be oil pipe
6, be left side turnover oilhole
7, be right turnover oilhole
8-1, be left cantilever
8-2, be right cantilever
Bottom is further described the utility model by reference to the accompanying drawings: such as Fig. 1-shown in Figure 2, a kind of for folding Waist turns to the hydraulic directio power assisting device of tractor, and its fuel tank 1 is arranged on the trailer right side, hydraulic gear pump 2 Be fixed on the position power taking that the gearbox right side makes things convenient for power taking, switching valve 3 is set together with steering wheel shaft. When When steering wheel turns left, open right valve, hydraulic oil enters right oil cylinder 4-2 pushing piston by the oil pipe on the right, Promote simultaneously right cantilever 8-2 direction rotation left, make the hydraulic oil of left oil cylinder 4-1 flow back to fuel tank; Work as steering wheel When turning right, open left valve, hydraulic oil enters left oil cylinder 4-1 pushing piston by the oil pipe on the left side, simultaneously Promote left cantilever 8-1 and rotate to right, make the hydraulic oil of right oil cylinder 4-2 flow back to fuel tank. Described left oil cylinder 4-1 and right oil cylinder 4-2 adopt two and singly go out the formula oil cylinder, so-calledly singly go out the formula oil cylinder, and an oil cylinder only in other words A turnover oilhole is arranged, and the utility model uses two and singly goes out the formula oil cylinder, and an oil cylinder is responsible for turning left to bow, Another oil cylinder is responsible for turning right and is bowed, two oil cylinder cooperatings, and the action of bowing about jointly finishing, Its strong point is arranged on the left and right sides of engine and the trailer handing-over point of rotation. Oil pipe 5 is with fuel tank 1 and hydraulic pressure tooth Wheel pump 2, hydraulic gear pump 2 and switching valve 3, switching valve 3 and left oil cylinder 4-1 be connected oil cylinder 4-2 and be connected.
The specific embodiment:
Embodiment 1, when bearing circle turns left, opens right valve, and hydraulic oil enters right oil cylinder 4-2 promotion piston by the oil pipe on the right, promotes right cantilever 8-2 direction rotation left simultaneously, makes the hydraulic oil of left oil cylinder 4-1 flow back to fuel tank; When the bearing circle turning clockwise, open left valve, hydraulic oil enters left oil cylinder 4-1 promotion piston by the oil pipe on the left side, promotes left cantilever 8-1 simultaneously and rotates to right, makes the hydraulic oil of right oil cylinder 4-2 flow back to fuel tank.
Claims (2)
