Description

A kind of economic benefits and social benefits damper for automobile
Technical field
Auto parts field is the utility model is related to, more particularly, to a kind of economic benefits and social benefits damper for automobile.
Background technology
Damper, also it is attenuator.Common damper includes hydra-shock absorber and mechanical damper.Fluid pressure type subtracts Shake device is divided into hydraulic damper and double-acting shock absorber again.Hydraulic damper is using the compressibility and liquid of liquid in compression The characteristic of dissipation energy, realizes the purpose for reducing or eliminating vibrations when absorbing energy and flowing.Double-acting shock absorber is except can be with Outside being compressed axially, torsional pulse can also be converted into axial impact, reduce or eliminate longitudinal direction using the principle of hydraulic shock-absorption Vibrations and torsional pulse.Mechanical damper has good damping effect, long working life, cost performance ratio.Damping The shape of device is a beam barrel, has a movable beam barrel or an axostylus axostyle again in beam barrel.Damper is placed in pendulum spring Portion, typically all it is connected with compartment and wheel support.Air pressure or its principle of hydraulic shock-absorption are similar.Generally use two kinds of methods are delayed Rush slip of the beam barrel in another beam barrel:One kind is hydraulic shock-absorption, uses special hydraulic oil;Another kind makes air pressure subtract Shake, use pressurization nitrogen.Damper is bidirectional-movement:When wheel sinks because of load or brake, damper just pressurizes;Work as automobile When recovering original load, damper just depressurizes.The principle of damper is in fact very simple.When it pressurizes, connect under wheel Pressure pipe rises, and piston is pushed into another beam barrel in connection compartment;There is standard aperture on piston, oil pressure mouth, profit are installed on hole Lubricating oil plays a part of damping shock absorber rising through oil pressure mouth.Conversely, wheel just recovers original under pendulum spring pressure Position.
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 economic benefits and social benefits damper for automobile 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 economic benefits and social benefits damper for automobile, it is special Sign is that the damper includes piston rod, piston, damper shell, damper inner casing;The piston is arranged on piston rod Bottom;The damper inner casing is arranged on the middle position of the inside of damper shell, and by damper shell divide into upper and lower Two closed chambers;Piston is arranged on the inside of damper inner casing through damper shell and damper inner casing by the piston rod; Being internally located at below piston for the damper inner casing is provided with spring;Fill and be provided with the damper inner casing and damper shell Damping oil.
Further, the economic benefits and social benefits damper of automobile is used for according to above-mentioned design, it is characterised in that the piston Side wall is provided with two circle grooves;Rubber ring is provided with the groove;The rubber ring is tapered towards the side of inside grooves;Institute The maximum outside diameter for stating rubber ring is equal to the internal diameter of damper inner casing.
Further, the economic benefits and social benefits damper of automobile is used for according to above-mentioned design, it is characterised in that the piston rod Top be provided with vehicle frame connection ring.
Further, the economic benefits and social benefits damper of automobile is used for according to above-mentioned design, it is characterised in that the damper The bottom of shell is provided with vehicle bridge connection ring.
Further, the economic benefits and social benefits damper of automobile is used for according to above-mentioned design, it is characterised in that the piston rod Upper end be connected with piston cover;The internal diameter of the piston cover is equal to the external diameter of damper shell;The piston cover, which is set in, to be subtracted Shake the outside of device shell.
Further, the economic benefits and social benefits damper of automobile is used for according to above-mentioned design, it is characterised in that the piston rod With being provided with sealing ring at damper inner casing and damper cage connection and being oriented to torus;The sealing ring is arranged on damper inner casing Or between 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, shape occurs for effect that the rubber ring that is arranged on piston side wall is under pressure Become so that damping oil flows between the inwall of piston and damper inner casing.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.The application is using pressure The excessively oily mode of power coordinates dual-thread buffer gear, can effectively improve buffering effect.
