Description
Technical field
The invention belongs to the Manufacturing Technology for Automotive Parts field, specifically, relate to a kind of vehicle shock absorber.
Background technique
At present, extensively adopt vibration damper in the automobile suspension system.Its principle is, does when moving back and forth in the cylinder barrel of reciprocal relative movement youngster piston at vibration damper when vehicle frame and vehicle bridge, and the fluid in the shock absorber casing just flows into another inner chamber from inner chamber by some narrow holes repeatedly.At this moment, the interior friction of the friction of liquid and inwall and fluid molecule just forms the damping force to vibration.
For the travelling comfort of vehicle is provided, the automobile chassis system all adopts vibration damper to carry out damping, buffering, because being hit, elastic element produces vibration in the vibration damper suspension system, for improving vehicle running smoothness, be installed in parallel vibration damper with elastic element in the suspension, be attenuation vibration, adopt vibration damper to be mostly hydraulic shock absorber in the automobile suspension system.The at this moment friction between hole wall and fluid and the intermolecular interior friction of fluid forms damping force to vibration, makes automobile vibrational energy be converted into fluid heat energy, absorbed by vibration damper to be dispersed in the atmosphere again.The fluid channel cross-section and etc. factor when constant, damping force increases and decreases with the speed of related movement between vehicle frame and the vehicle bridge (or wheel), and relevant with oil viscosity.Vibration damper and elastic element are being born the task of buffer and vibration damping, and damping force is excessive, and suspension elasticity will be degenerated, even the vibration damper link is damaged.Because face is wanted adjustable elastic element and this contradiction of vibration damper.(1) compression stroke (vehicle bridge and vehicle frame are mutually close), absorber damping force is less, in order to give full play to the elastic reaction of elastic element, relaxes and impacts.At this moment, elastic element plays a major role.(2) in the suspension extension stroke (vehicle bridge and vehicle frame mutually away from), absorber damping force should be large, rapidly vibration damping.(3) when vehicle bridge (or wheel) and interaxle relative velocity are excessive, require vibration damper automatically to strengthen flow quantity, damping force is remained within the certain limit, to avoid bearing excessive impulsive load.
In the middle of existing suspension system, the effect of vibration damper is very important, also seem very necessary for the dustproof of vibration damper, general vibration damper all is equipped with dust-proof cover, the dust-proof cover of rear shock absorber of the prior art is open (non-vibration damper and spring is integrated), and namely the dust-proof cover bottom is developed, and with the vibration damper urceolus certain gap is arranged, therefore, there are many technical problems in shock absorber dirt shield of the prior art:
1, because dust-proof cover of the prior art employing is open, and open dust-proof cover has dust or silt is deposited on oil sealing and the piston rod by lower openings, causes the scuffing of piston rod and oil sealing, causes leakage of oil, thereby reduces working life.
2, because dust-proof cover of the prior art employing is open, cause the vibration damper hair fastener, when serious, will make the vibration damper cisco unity malfunction, greatly affect the comfort property of car load.
3, spend when shrinking when vibration damper of the prior art more, often cause the excessively long-term extruding of dust-proof cover and damage.
Summary of the invention
Technical problem to be solved by this invention is, because it is open that dust-proof cover of the prior art adopts, with the vibration damper urceolus certain gap is arranged, open dust-proof cover has dust or silt is deposited on oil sealing and the piston rod by lower openings, cause the scuffing of piston rod and oil sealing, cause leakage of oil, thereby reduce working life; Cause the vibration damper hair fastener, when serious, will make the vibration damper cisco unity malfunction, greatly affect the comfort property of car load, dust-proof cover pushes and the technical problems such as damage excessively for a long time, and a kind of vehicle shock absorber is provided.
Technical conceive of the present invention is, for solving above-mentioned vehicle shock absorber leakage of oil, hair fastener, reduction working life, cisco unity malfunction lamp technical problem, and design a kind of novel damper means, damper means comprises the dust guard that is combined by a weak section and firm section, remove and install conveniently, can effectively carry out dustproof effect, reduce damper leakage and the probability that causes losing efficacy.
Technological scheme provided by the present invention is, a kind of vehicle shock absorber, comprise damper cylinder, piston assembly, seal element, upper connection hole and lower connection hole, a described piston part is arranged in the described cylindrical shell, described damper cylinder and described piston joint are provided with seal element, described vibration damper also is provided with dust guard, and described dust guard is made of flexible part and rigid portion.
Described dust guard is arranged in the upper end portion of described damper cylinder, the periphery of described piston assembly in the described dust guard parcel.
Described dust guard flexible part is provided with some folds, and the upper end of described flexible part is provided with closing-in structure.
Described piston assembly comprises the piston rod draw-in groove, and described piston rod draw-in groove is arranged in the coupling shaft bottom that vibration damper is connected with car body.
The closing in of described dust guard flexible part cooperates installation with described piston rod draw-in groove, and described flexible part closes up and is fixed in the described piston rod draw-in groove by clip.
Described dust guard rigid portion is a cylindrical shell, and described cylindrical shell is connected with described damper cylinder top suit.
Be provided with sliding ring between described cylindrical shell and the described damper cylinder, the internal surface of described cylindrical shell lower end is provided with seal groove, and described sliding ring is fixed in the described seal groove.
The flexible part of described dust guard is connected with described rigid portion, and described rigid portion upper end is provided with connecting groove.
Described flexible part lower end is fixed in the connecting groove of described rigid portion by clip.
Described piston assembly comprises the piston rod draw-in groove.
Adopt technological scheme provided by the present invention, can solve effectively that open dust-proof cover of the prior art has dust or silt is deposited on oil sealing and the piston rod by lower openings, cause the scuffing of piston rod and oil sealing, cause leakage of oil, thereby reduce working life; Cause the vibration damper hair fastener, when serious, will make the vibration damper cisco unity malfunction, greatly affect the excessively long-term extruding of comfort property, dust-proof cover of car load and the technical problems such as damage also have good dustproof effect simultaneously, long service life, low cost of manufacture, the advantages such as good operating stability.
