Description
Technical field
The utility model relates to a kind of auto parts machinery, relates to specifically a kind of automobile absorber.
Background technique
In the vehicle traveling process, produce vibration because elastic element is hit in the suspension system, for improving vehicle running smoothness, be installed in parallel vibration damper with elastic element in the suspension.At present, common vibration damper is double-barrel structure (being inner core and urceolus) and adopts high pressure sealing gas in the automobile, and its structure and production technology be more complicated all.Owing to adopted high pressure sealing gas, when piston rod is up and down, be bonded at rod seal place if any harder dust granule, easily make piston rod cause cut, cause high pressure sealing Leakage Gas, loss, underpressure, cause the vibration damper cisco unity malfunction, even scrap.Because gas has and expands with heat and contract with cold, so high pressure sealing gas temperature influence is serious, cost is high, and is fragile, and external characteristics, external force speed responsive ability etc. are all very poor.In addition, filling high pressure sealing gas needs the special device High Pressure Gun, complexity is installed, and it is extremely inconvenient to transport such vibration damper, when improper operation is arranged, makes pressurized gas leak into pistons work chamber inner core, causes damping performance to descend.Such vibration damper is scrapped processing and is also very bothered, because after scrapping, remains hazmat, in case be heated, easily sets off an explosion, and causes the accident.
Application number: 201120212428.4, notice of authorization number: the automobile absorber of CN 202140498 U comprises the frame of sealing, valve formula oil hole and needle-like outlet valve are housed on the frame, be provided with piston and piston rod in the frame, be evenly equipped with a plurality ofly vertically through the discharge orifice of piston on the piston, the top of the frame of sealing is passed in the upper end on the piston rod; Bottom in the frame is put into flexible thing and netted lid from bottom to up, is full of hydraulic oil between piston and the netted lid; The bottom of the frame outside of the top of piston rod and sealing is provided with retaining ring respectively; Be equipped with an one-way valve on each discharge orifice, the position of the one-way valve on per two adjacent discharge orifices is top and bottom (discharge orifice is the apical position that one-way valve is located at discharge orifice, and another discharge orifice then is the place, bottom that one-way valve is located at discharge orifice) that is arranged on alternately the place discharge orifice.This automobile absorber has solved the high technical barrier of cost that current shock absorber structure is complicated, adopt high pressure sealing gas to bring.
Be mixed with impurity or foreign matter in the hydraulic oil, during automobile absorber work, the friction between meeting oversize piston and the housing, the wearing and tearing of accelerating piston and housing, the working life of shortening automobile absorber; Simultaneously, impurity or foreign matter may stop up one-way valve, can cause the vibration damper cisco unity malfunction equally.
The hydraulic automobile absorber used after a period of time, inevitably the oil impregnate phenomenon can occur, in order to guarantee the usability of automobile absorber, needed to inject new hydraulic oil.And using a period of time automobile absorber afterwards, valve formula oil hole can be contaminated, and this automobile absorber self does not have filter, when injecting new hydraulic oil, impurity and foreign matter very easily are injected into, and can't guarantee the cleaning of hydraulic oil, thereby have shortened the working life of automobile absorber.
The model utility content
Can't guarantee the problem of the cleaning of hydraulic oil for existing hydraulic automobile absorber, the purpose of this utility model is to provide a kind of automobile absorber that can guarantee cleanliness of hydraulic oil.
The utility model is achieved through the following technical solutions:
A kind of automobile absorber comprises that frame, the frame of sealing is provided with valve formula oil hole, and it is characterized in that: described valve formula oil hole is equipped with dismountable hydraulic oil filter.
The utility model also has following technical characteristics:
Described hydraulic oil filter is filter screen or filter.
Be provided with the needle-like outlet valve on the described frame; Be provided with piston and piston rod in the frame, be evenly equipped with many discharge orifices to connecting on the piston, the top of frame is passed in the upper end of piston rod; Bottom in the frame is put into flexible thing and netted lid from bottom to up, is full of hydraulic oil between piston and the netted lid; The bottom of the top of piston rod and frame outside is equipped with retaining ring; Be equipped with an one-way valve on each discharge orifice, the position of the one-way valve on each discharge orifice is top or the bottom that is arranged on alternately discharge orifice.
The working principle of the automobile absorber that the utility model provides:
In the vehicle traveling process, when automotive wheel shifts near vehicle body, vibration damper is by compression the time, and this moment, the vibration damper inner carrier moved down.The volume reducing of piston lower chambers, oil pressure raises, the chamber of fluid above one-way valve flows to piston.One-way valve forms the damping force that suspension moves by compression to the throttling of oil.Vibration damper at wheel away from vehicle body, the vibration damper Tensile, at this moment the piston of vibration damper moves up.The piston upper chamber oil pressure raises, the chamber of fluid below one-way valve flows to piston.Because the throttling action of one-way valve plays damping function when doing extending movement to being suspended in.Thereby reached the effect of damping.
When the injection liquid force feed, the filtrating equipment that is installed in oil hole can filter out the impurity in the hydraulic oil, guarantees the cleaning of the hydraulic oil in the automobile absorber housing.
Compared with prior art, the utlity model has following beneficial effect:
One, the automobile absorber that provides of the utility model is equipped with hydraulic oil filter at valve formula oil hole, can be in the process of injection liquid force feed, the impurity in the elimination external world and foreign matter can guarantee the cleaning of hydraulic oil, thereby have increased the working life of automobile absorber.
Two, the automobile absorber that provides of the utility model is equipped with dismountable hydraulic oil filter at valve formula oil hole, can be according to use condition, at any time with changing filtrating equipment, to guarantee the cleaning of hydraulic oil.Have characteristics easy to use.
