Description
Technical field
The present invention relates to a kind of hydraulic cylinder, particularly a kind of linkage hydraulic cylinder.
Background technology
The hydraulic pressure that hydraulic energy is changed into mechanical energy by hydraulic cylinder, do straight reciprocating motion or oscillating motion is held
Units.Hydraulic cylinder is substantially made up of cylinder barrel and cylinder cap, piston and piston rod, sealing device, according to often
By the version of hydraulic cylinder, four types can be classified as: piston type, plunger type, telescopic, swing
Formula.Piston type single-piston-rod hydraulic cylinder only has one end to have piston rod, is a kind of single-piston hydraulic cylinder.Its two ends
Import and export hydraulic fluid port and all can lead to pressure oil or oil return, to realize bidirectional-movement, therefore referred to as double acting cylinder, piston
Being only capable of one-way movement, the motion of its opposite direction need to be completed by external force.Plunger-type cylinder is a kind of single-acting formula
Hydraulic cylinder, can only realize the motion in a direction by hydraulic coupling, and other external force or plunger are leaned in plunger backhaul
Deadweight；Plunger does not only contact with cylinder sleeve by cylinder sleeve supporting, and such cylinder sleeve is easily processed, therefore is suitable to do long row
Journey hydraulic cylinder；Plunger total pressurized during work, thus it must have enough rigidity；Piston is only capable of one-way movement,
The motion of its opposite direction need to be completed by external force, but its stroke is the biggest compared with piston-type hydraulic cylinder.Telescopic hydraulic
Cylinder has two grades or multi-level piston, and the sequential that in telescoping hydraulic cylinder, piston stretches out is from big to small, and unloaded
The order retracted then is usually from small to large；Telescoping cylinder can realize longer stroke, and when retracting, length is shorter,
Structure is the compactest, and this kind of hydraulic cylinder is usually used on engineering machinery and agricultural machinery.Spiral swing hydranlic pressure jar is defeated
Go out moment of torsion and realize reciprocating executive component, also referred to as oscillatory motor, having single blade and twayblade
Two kinds of forms, stator block is fixed on cylinder body, and blade and rotor link together, according to oil-feed direction,
Rotor driven is made reciprocally swinging by blade.Current various single hydraulic cylinder be all hydraulic system perform unit
Part, hydraulic system also includes hydraulic power source and control system, executes control hydraulic pressure by hydraulic power source and hydraulic control system
Cylinder, its hydraulic power source and hydraulic control system configuration are complicated, and cost is higher, and pass through at hydraulic oil
During hydraulic control system, hydraulic pressure often produces a certain degree of loss phenomenon.
