Description
Technical field
Auto parts field is the utility model is related to, more particularly, to a kind of hydra-shock absorber for automobile shock.
Background technology
Damper, also it is attenuator.Common damper includes hydra-shock absorber and mechanical damper.Fluid pressure type
Damper is divided into hydraulic damper and double-acting shock absorber again.Hydraulic damper is being compressed using the compressibility and liquid of liquid
When absorb energy and flowing when dissipation energy characteristic, realize reduce or eliminate vibrations purpose.Double-acting shock absorber is except can
It is outer to be compressed axially, torsional pulse can also be converted into axial impact, reduce or eliminate using the principle of hydraulic shock-absorption and be vertical
To vibrations and torsional pulse.Mechanical damper has good damping effect, long working life, cost performance ratio.Subtract
The shape of shake device is a beam barrel, has a movable beam barrel or an axostylus axostyle again in beam barrel.Damper is placed in pendulum spring
Inside, typically all it is connected with compartment and wheel support.Air pressure or its principle of hydraulic shock-absorption are similar.Two kinds of methods of generally use are come
Buffer slip of the beam barrel in another beam barrel：One kind is hydraulic shock-absorption, uses special hydraulic oil；Another kind is air pressure
Damping, use pressurization nitrogen.Damper is bidirectional-movement：When wheel sinks because of load or brake, damper just pressurizes；Work as vapour
When car recovers original load, damper just depressurizes.The principle of damper is in fact very simple.When it pressurizes, wheel is connected
Lower pressure pipe rises, and piston is pushed into another beam barrel in connection compartment；There is standard aperture on piston, oil pressure mouth be installed on hole,
Lubricating oil plays a part of damping shock absorber rising through oil pressure mouth.Conversely, wheel just recovers former under pendulum spring pressure
The position come.
The hydra-shock absorber of prior art, it is complicated, it is high for technological requirement, and the hydraulic shock-absorption of prior art
Device is the damping pattern using single thread, it is impossible to which damping step by step by different level, damping effect is not good enough, and it is small to be applicable pressure limit.
The content of the invention
Problem to be solved in the utility model is, for it is above-mentioned in the prior art the shortcomings that, propose improvement project or
Alternative, especially a kind of hydra-shock absorber for automobile shock that dual-thread damping can be provided.
To solve the above problems, the scheme that the utility model uses is as follows：A kind of hydra-shock absorber for automobile, its

Lower two closed chambers；Piston is arranged in damper inner casing by the piston rod through damper shell and damper inner casing
Portion；Being internally located at below piston for the damper inner casing is provided with spring；Filled in the damper inner casing and damper shell
Provided with damping oil；The side of the piston is provided with sealing ring；The piston is provided with the curved hole through piston upper and lower surface.
Further, the hydra-shock absorber of automobile is used for according to above-mentioned design, it is characterised in that described to run through
The curved hole of piston upper and lower surface is N font structures；The internal diameter of curved hole on the piston is less than 0.5 millimeter.
Further, the hydra-shock absorber of automobile is used for according to above-mentioned design, it is characterised in that the piston
The top of bar is provided with vehicle frame connection ring.
Further, the hydra-shock absorber of automobile is used for according to above-mentioned design, it is characterised in that the damping
The bottom of device shell is provided with vehicle bridge connection ring.
Further, the hydra-shock absorber of automobile is used for according to above-mentioned design, it is characterised in that the piston
The upper end of bar is connected with piston cover；The internal diameter of the piston cover is equal to the external diameter of damper shell；The piston cover is set in
The outside of damper shell.
Further, the hydra-shock absorber of automobile is used for according to above-mentioned design, it is characterised in that the piston
Bar is with being provided with sealing ring and being oriented to torus at damper inner casing and damper cage connection；The sealing ring is arranged in damper
Between shell or damper shell and guiding torus.
Technique effect of the present utility model is as follows：The hydra-shock absorber of the application is by inside and outside setting outside two layers of damper
Shell, two damping threads are set.Damper inner casing is arranged on to the inside of damper shell first, by damper shell divide into
Upper and lower two closed chambers, and filled in intracavitary and set damping oil, piston rod is arranged on and subtracted through damper shell and damper inner casing
The inside of device inner casing is shaken, when piston rod movement, is provided in the piston of piston rod end first in the inside of damper inner casing
Motion, by fill the damping oil being located in damper inner casing to vibrations pressure enter row buffering, the buffering thread be for pressure compared with
Small vibrations, when vibrations pressure is non-really big, piston is when the internal motion buffering of damper inner casing can not discharge the pressure, then
Damper inner casing moves in damper shell, and this is the second thread pooling damping, and the dual-thread bumper and absorbing shock of the application can
It is highly effective to solve the problems, such as that prior art perfect solve for the vibrations pressure that span increases.
The piston of the damper of the application is arranged on the inside of damper inner casing, and is filled in damper inner casing and set damping
Oil, when piston rod stress pushes down on piston, it is arranged on the curved hole on piston through piston upper and lower surface and is used for damping of circulating
Oil so that damping oil can be flowed to above piston in damper inner housing inner below piston by curved hole.So as to play one-level
Cushioning effect.
What the damper inner casing of the damper of the application was arranged on damper shell is internally located at centre position, by damper
Shell divide fills damping oil or lubricating oil into upper and lower two chambers, and in intracavitary, and the volume of damping oil is the body of chamber
Long-pending 1/3rd.When damper inner casing is after by the pressure of piston, damper inner casing is moved, to damper shell
Gas and damping oil or lubricating oil the release vibrations pressure of intracavitary.So as to realize second level cushioning effect.
