Description

A kind of hydro-pneumatic spring cylinder
Technical field
The utility model relates to a kind of hydro-pneumatic spring cylinder, belongs to hydro-pneumatic spring cylinder structure technical field.
Background technique
At present, existing vehicle vibration damping is the split oil gas damping that oil cylinder and accumulator combine mutually, and damping effect is not obvious, and cost is higher, and pipeline connects complicated, and it is unreliable to seal, and installation and maintenance are more difficult, take up room larger.
Summary of the invention
The purpose of this utility model is to solve the deficiency that above-mentioned prior art exists, and provides a kind of
Fabricating cost is cheap, easy to maintenance, and good damping result does not need to configure other special device when use
Hydro-pneumatic spring cylinder.
The utility model is achieved through the following technical solutions:
A kind of hydro-pneumatic spring cylinder, its special way is to comprise the air cavity 11, transition oil pocket 12, the oil pocket 13 that are filled with nitrogen, air cavity 11 is isolated by floating piston 10 with transition oil pocket 12, one-way throttle valve 14 and damping hole 9 are installed between transition oil pocket 12 and oil pocket 13, the outside of air cavity 11 is provided with the cylinder barrel 3 with its interlock, transition oil pocket 12 is located in cylinder barrel 3, and the outside of cylinder barrel 3 is provided with cylinder tube 4, and oil pocket 13 is located in cylinder tube 4;
In order to ensure that air cavity 11 does not communicate with the external world, on described air cavity 11, be also provided with gas charging valve assembly 2;
Described cylinder barrel 3 is provided with the upper journal 1 due to connecting vehicle frame, and cylinder tube 4 is provided with the down journal 6 for connecting vehicle frame, and down journal 6 is fixed on the outer wall of cylinder barrel 4 by locking nut 5.
Hydro-pneumatic spring cylinder structure of the present utility model is reasonable in design, be used in conjunction with by air cavity, transition oil pocket, oil pocket three, can effectively avoid because injustice is jolted and various vibrations and impact that automobile is caused in ground, effectiveness in vibration suppression is good, can ensure steadily transporting safely of accurate load-bearing instrument, be the developing direction of high-tech product.
Brief description of the drawings
Fig. 1: the structural representation of a kind of hydro-pneumatic spring cylinder of the utility model;
Fig. 2: the structure for amplifying schematic diagram of the utility model one-way throttle valve and damping hole.
Embodiment
Provide embodiment of the present utility model below with reference to accompanying drawing, be used for the utility model to be described further.
Embodiment 1
A kind of hydro-pneumatic spring cylinder of the present embodiment, comprise the air cavity 11, transition oil pocket 12, the oil pocket 13 that are filled with nitrogen, air cavity 11 is isolated by floating piston 10 with transition oil pocket 12, one-way throttle valve 14 and damping hole 9 are installed between transition oil pocket 12 and oil pocket 13, the outside of air cavity 11 is provided with the cylinder barrel 3 with its interlock, transition oil pocket 12 is located in cylinder barrel 3, and the outside of cylinder barrel 3 is provided with cylinder tube 4, and oil pocket 13 is located in cylinder tube 4; Ensure that air cavity 11 does not communicate with the external world, on described air cavity 11, be also provided with gas charging valve assembly 2; Cylinder barrel 3 is provided with the upper journal 1 due to connecting vehicle frame, and cylinder tube 4 is provided with the down journal 6 for connecting vehicle frame, and down journal 6 is fixed on the outer wall of cylinder barrel 4 by locking nut 5.
Working principle: when work, in air cavity 11, be filled with the industrial nitrogen of 3.2MPa, air cavity 11 is sealed rear formation gas spring by floating piston 10, in transition oil pocket 12, has been full of hydraulic oil, with oil pocket 13 joint work, the high pressure oil of supplying with, directly enters oil pocket 13, enters transition oil pocket 12 by one-way throttle valve 14, promote floating piston 10, compression air cavity 11, also promotes cylinder barrel 3 and stretches out, jack-up load simultaneously; After release, cylinder barrel 3 bounces back under the effect of external force, and pressurized gas promote floating piston 10 simultaneously, through transition oil pocket 12, is relaxed and is discharged by one-way throttle valve 14, forms a cyclic process.
