Abstract
The utility model discloses a steering oil cylinder for a forklift, which comprises cylinder barrel, a piston is arranged in the cylinder barrel, and two ends of the cylinder barrel are respectively covered by a cylinder cover. A piston rod penetrates through two ends of the piston and extends out from two ends of the cylinder barrel by passing through the cylinder covers, and two sides of the piston is the cylinder barrel are respectively provided with an oil port. The steering oil cylinder for the forklift is simple in structure, convenient to manufacture and reliable in steering and has no damage caused by mechanical friction. In addition, the piston rod is flexible in back and forth movement along both sides.
Description
Technical field
It mainly is that a kind of fork truck is with turning to oil cylinder that the utility model relates to a kind of hydraulic jack.
Background technique
Need control direction of travel during fork truck work, thereby just need to turn to in-oil cylinder piston rod just need to control through connected commutator and multi-way valve more like this to the both sides back and forth movement by turning to oil cylinder to drive the swing about wheel.
The model utility content
The utility model technical problem to be solved provides a kind of fork truck with turning to oil cylinder, and it is simple in structure, and is easy to make, and piston rod is sensitive to the both sides back and forth movement, turns to reliably, does not have the infringement that the machinery friction causes.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is:
A kind of fork truck includes cylinder barrel with turning to oil cylinder, and piston is installed in the cylinder barrel, and cylinder cap is stamped at the two ends of said cylinder barrel respectively; Have piston rod to pass the two ends of piston and stretch out from the two ends of cylinder barrel through cylinder cap, the both sides of said cylinder barrel inner carrier are respectively equipped with hydraulic fluid port.
The cylinder cap that be stamped at said cylinder barrel two ends contacts and is provided with the O RunddichtringO with inner wall of cylinder; The said piston rod that stretches out through cylinder cap with the surface of contact of cylinder cap on be provided with pad and U RunddichtringO.
Sealing that adopts in the utility model and pad make the utility model compact structure, good seal performance, the working life of improving oil cylinder.
The hydraulic fluid port of cylinder barrel inner carrier both sides can exchange as oil inlet and outlet in the utility model.
The utility model is to realize turning to of fork truck by gear pump supply pressure oil through the control back and forth movement drive shimmy of multi-way valve and commutator.
The necessary cleaning and removing burr of all parts will be coated with lubricant oil before the assembling of relative movement face before the utility model assembling, and the oil cylinder assembling is accomplished, and piston must not have the retardance phenomenon when total travel moves.
The utility model has the advantages that:
It is simple in structure, easy to make for the utility model, and piston rod is sensitive to the both sides back and forth movement, turns to reliably, does not have the infringement that the machinery friction causes.
