Abstract
The utility model relates to a farm tractor, in particular to a hydraulic direction assisting device of single-cylinder vertical articulated tractor. The hydraulic direction assisting device of single-cylinder vertical articulated tractor comprises an oil box 1, a hydraulic gear pump 2, a rotary valve 3, an oil cylinder 4 and an oil pipe 5. The hydraulic direction assisting device of single-cylinder vertical articulated tractor is characterized in that input power of the hydraulic gear pump 2 is provided by a grooved pulley 10 arranged on the outer end of a manual starting shaft of a tractor engine. The hydraulic direction assisting device of single-cylinder vertical articulated tractor has small volume, compact structure, low manufacture cost, reliable and stable work, rational distribution, and light and flexible operation of a steering wheel, the hydraulic direction assisting device of single-cylinder vertical articulated tractor can guarantee that a traversing mechanism can not fail no matter when the vehicle is stopped or a foot treads a clutch under the condition that only a diesel engine is started, and the assurance coefficients are greatly improved.
Description
Technical field
The utility model relates to a kind of farm tractor, relates to the hydraulic directio work-saving device of the vertical articulated steering trac. of a kind of single cylinder 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, safety factor is poor, and transmission link is many, and the bearing circle operation is overweight and manufacturing cost is high.Use the hydraulic directio work-saving device instead in order to overcome above-mentioned shortcoming, also to have, but their all power takings after engine clucht, and the result causes the parking rear malfunctioning to machine, safety factor is reduced greatly.
The utility model content
The purpose of this utility model provides a kind of can the assurance at diesel engine as long as under situation about starting, the direction machine can be not malfunctioning when being parking or pedal clutch, the hydraulic directio work-saving device of the vertical articulated steering trac. of the single cylinder that safety factor improves greatly.
In order to achieve the above object, the technical solution of the utility model is achieved like this: the hydraulic directio work-saving device of the vertical articulated steering trac. of a kind of single cylinder, comprise fuel tank 1, hydraulic gear pump 2, convertible valve 3, oil cylinder 4, oil pipe 5 is characterized in that: the imput power of described hydraulic gear pump 2 is provided by the pulley conical disk 10 that is arranged on trac. engine hand starting axle outer end.
The central shaft hole of described pulley conical disk 10 is installed on the trac. engine hand starting axle, and pulley conical disk 10 is connected with hydraulic gear pump input belt pulley 9 by cone belt 11.
The utility model beneficial effect is:
It is little to the utlity model has volume, compact conformation, low cost of manufacture, reliable and stable work, rationally distributed, bearing circle operation light and flexible, can guarantee to need only under the situation about starting at diesel engine, the direction machine can be not malfunctioning when being parking or pedal clutch, and safety factor improves greatly.

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 any one of the trailer left and right sides The position all can, the utility model is selected at the right side. Hydraulic gear pump 2 is fixed on about the tractor engine two Any one position of side all can, wooden utility model be selected at the left side. Failing of described hydraulic gear pump 2 Entering power is provided by the pulley concial disk 10 that is arranged on tractor engine hand starting axle outer end. Described triangle The central shaft hole of belt pulley 10 is installed on the tractor engine hand starting axle, and pulley concial disk 10 is by three Cuticle band 11 is connected with hydraulic gear pump input belt pulley 9. Switching valve 3 is set together with steering wheel shaft. When steering wheel turns left, open right valve, hydraulic oil enters right oil cylinder 4-2 promotion work by the oil pipe on the right Plug promotes right cantilever 8-2 direction rotation left simultaneously, makes the hydraulic oil of left oil cylinder 4-1 flow back to fuel tank; The side of working as When turning right to dish, open left valve, hydraulic oil enters left oil cylinder 4-1 pushing piston by the oil pipe on the left side, Promote simultaneously left cantilever 8-1 and rotate to right, make the hydraulic oil of right oil cylinder 4-2 flow back to fuel tank. A described left side 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 formula oil cylinder, in other words an oil Cylinder only has a turnover oilhole, and the utility model uses two and singly goes out the formula oil cylinder, and an oil cylinder is responsible for folding Waist, another oil cylinder are responsible for turning right and are bowed, two oil cylinder cooperatings, and that bows about jointly finishing is moving Do, 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 liquid Press gear pump 2, hydraulic gear pump 2 and switching valve 3, switching valve 3 connects with left oil cylinder 4-1 and right oil cylinder 4-2 Connect.
The specific embodiment:
Embodiment 1, behind the diesel engine starting, pulley conical disk 10 drives hydraulic gear pump input belt pulley 9 by cone belt 11 and rotates, hydraulic gear pump changes normal working over to, when bearing circle turns left, open right valve, hydraulic oil enters right oil cylinder 4-2 promotion piston by the oil pipe on the right, promote right cantilever 8-2 direction rotation left simultaneously, make 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.
