The utility model can be applied conveniently and directly on Shanghai-50 Model tractors to realize hydraulic power steering of Shanghai-50 Model tractors to realize flexible and labor-saving steering operations, safe and reliable, thus can improve the work efficiency; besides, the utility model has a compact structure and a regular outlook, and can be blended with the tractor to ensure overall beauty and strong integrity.
Description
Technical field
The utility model relates to a kind of improved tractor hydraulic assisted power steering system, the suitable especially repacking to Shanghai 50 type tractor steering mechanisms.
Background technology
Shanghai 50 type trac.s are types of China's rural area recoverable amount maximum, and for many years, this machine adopts traditional mechanical steering gear mode always, is used for the over-the-road transportation operation.Now, because having withdrawed from transport field, this machine of development of Transport Machinery becomes special-purpose farm working machinery, the main working parts of its main supporting machinery wheat and rice combine harvester, corn combine all is positioned over the trac. front end, increased the farm tractor front axle load, steering operation is very required great effort, influence operating efficiency, and, man-machine accident takes place easily because of turning to overload to cause the damage of steering swivel system parts.
The utility model content
The purpose of this utility model is to provide a kind of tractor hydraulic assisted power steering system, and steering operation is flexible, laborsaving, and is easy for installation, safe and reliable, is beneficial to the raising operating efficiency.
Tractor hydraulic assisted power steering system described in the utility model, turn to assembly, setting is fixed on the oil cylinder permanent seat on the farm tractor front axle, turn to oil cylinder to be fixed on the oil cylinder permanent seat, turning to oil cylinder is double acting two ends reach structures, two ends are respectively equipped with piston rod, the two-piston bar connects the spindle arm of both sides respectively by adjust bar, the other end of spindle arm connects the trac. front-wheel steering spare on the propons, turn to the delivery line of oil cylinder to be communicated with the fluid-link steering assembly, and then be communicated with power steerig pump and turn to fuel tank.
The utility model is realized hydraulic power-assisted steering by hydraulic ram is set, for this reason, need be the fluid-link steering assembly with original mechanical steering unit replacement, main working parts comprises BZZ type cycloid steering valve all-hydraulic steering gear, combination valve block, bearing circle etc. in the fluid-link steering assembly, existing approved product, be used widely on the trac. of automobile or other model, market is on sale, can directly buy; Related accessories can be adjusted as required, satisfies operating needs, as deflector seat, steering shaft, sleeve pipe etc., realizes turning to control.Power steerig pump can be selected CBN type gear type pump for use, realizes supplying with oil of hydraulic efficiency gear.
Steering hydraulic is independent of tractor hydraulic system, and power steerig pump can be installed in the engine speed indicator place of trac. by Connection Block, adopts sliding cross coupling to connect power steerig pump and engines distribution cam axle, obtains power.
Delivery line uses the flexible pipe for one section except that connection turns to oil cylinder, and all the other all use steel pipe, and are safe and reliable.
Principle of work:
Power steerig pump will turn to the hydraulic oil in the fuel tank to supply with the fluid-link steering assembly, the flow direction of fluid-link steering assembly modulated pressure oil, thereby control steering oil cylinder piston rod is flexible, makes the deflection of trac. front-wheel steering spare by adjust bar and spindle arm, realizes turning to of trac..
The utility model tractor hydraulic assisted power steering system can directly be fitted on the 50 type trac.s of Shanghai easily, makes Shanghai 50 type trac.s realize hydraulic power-assisted steering, and steering operation is flexible, laborsaving, and is safe and reliable, is beneficial to the raising operating efficiency.And compact conformation, outward appearance is neat, and molten with trac. is one, and elegant in appearance, globality is strong.
Description of drawings
Fig. 1, the utility model one example structure scheme drawing.
Among the figure: 1, turn to oil cylinder 2, oil cylinder permanent seat 3, adjust bar 4, spindle arm 5, farm tractor front axle 6, power steerig pump 7, delivery line 8, turn to fuel tank 9, fluid-link steering assembly.
The specific embodiment
The utility model is described in further detail below in conjunction with the embodiment accompanying drawing.
As shown in the figure, tractor hydraulic assisted power steering system described in the utility model, the oil cylinder permanent seat 2 that is fixed on the farm tractor front axle 5 is arranged, turn to oil cylinder 1 to be fixed on the oil cylinder permanent seat 2, turn to oil cylinder 1 to be double acting two ends reach structure, two ends are respectively equipped with piston rod 3 etc., the two-piston bar passes through the spindle arm 4 of both sides such as connection such as adjust bar 3 grades etc. respectively, the other end of spindle arm 4 grades connects the trac. front-wheel steering spare on the farm tractor front axle 5, turn to the delivery line 7 of oil cylinder 1 to be communicated with fluid-link steering assembly 9, and then be communicated with power steerig pump 6 and turn to fuel tank 8.
