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 3, an oil cylinder 4 and an oil pipe 5. The hydraulic direction power-assisting device is characterized in that a double-piston oil cylinder is adopted as the oil cylinder 4; the support point of the oil cylinders can be arranged on any position of 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.Its complex structure, layout is unreasonable, and piece volumes is excessive, and the mechanical power transmission is dumb, and 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., comprise fuel tank 1, hydraulic gear pump 2, convertible valve 3, oil cylinder 4, oil pipe 5, it is characterized in that: described oil cylinder 4 adopts one twoly to go out the formula oil cylinder, and its strong point is arranged on engine and trailer and joins any one position of the pivot point left and right sides and all can.
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, be oil cylinder
5, be oil pipe
6, be the turnover oilhole
7, be the turnover oilhole
8, be strong point push rod
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 left valve, hydraulic oil enters oil cylinder 4 compression pistons by turnover oilhole 6, Promote to the left direction rotation of strong point push rod 8; When steering wheel turns right, open right valve, hydraulic oil Enter oil cylinder 4 compression pistons by turnover oilhole 7, promote to the right direction rotation of strong point push rod 8. The institute The oil cylinder 4 of stating adopts one pair to go out the formula oil cylinder, and so-called pair goes out the formula oil cylinder, and an oil cylinder has two in other words The turnover oil pipe, the piston of oil cylinder is in the centre, whole the moving of bowing about finishing by the move left and right of piston Do. Its strong point be arranged on engine and the trailer handing-over point of rotation the left and right sides any one position all can, The utility model is selected at the left side. Oil pipe 5 is fuel tank 1 and hydraulic gear pump 2, hydraulic gear pump 2 with turn to To valve 3, switching valve 3 is connected with oil cylinder 4.
The specific embodiment:
