Description
Technical field
This utility model belongs to absorber technical field, relates to the oil sealing dustproof construction of a kind of vibroshock.
Background technology
Equipped with vibroshock inside the suspension system of most of automobiles, vibroshock reduces vibrations, flat to improve the traveling of automobile
Pliable.
Existing vibroshock, such as Chinese patent literature data disclose automobile absorber [application number: 99216227.0；
Authorization Notice No.: CN2382587Y], it includes connecting rod, the oil sealing that is provided thereon, guider, buffer stopper and to be located at it outer
Working cylinder is also connected with oil storage chamber through bottom valve, is located at oil sealing in the front end of guider and steps down chamber, and it is built-in with the supporting of oil sealing steel plate
Oil sealing, and the front end of fuel tank bag be equipped with dust cover.
The vibroshock of this kind of structure, dust cover plays dust-proof and sediment prevention effect, but owing to the quantity of oil sealing only has one
Individual, arranging when traveling is paddled on the chassis of automobile of single oil sealing, the silt in water still can enter into vibration damping by dust cover
In the oil sealing of device, invading a large amount of silt in oil sealing, silt scratches oil sealing, so that oil sealing loses the effect of closure, causes vibration damping
The leakage of device fluid, causes absorber damping force to lose efficacy.
Summary of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, it is proposed that the oil sealing of a kind of vibroshock
Dustproof construction, solves the technical problem that it is how to make the vibroshock will not leakage of oil.
The purpose of this utility model can be realized by following technical proposal: the oil sealing dustproof construction of a kind of vibroshock, subtracts
The device that shakes includes that fuel tank, piston rod, guider, described guider are fixed on the top of fuel tank, and described piston rod is through guiding
Device, it is characterised in that described oil sealing dustproof construction includes main oil sealing, secondary oil sealing and dust cover, described main oil sealing is positioned at secondary oil sealing
With between guider, described main oil sealing is fixed on the inner side on fuel tank top, the inner side of described main oil sealing and the circumference of piston rod
Outside fits, and described dust cover is fixed on the outside on fuel tank top, has recessed installation cavity in described dust cover, described
Secondary oil sealing is fixed in installation cavity, and the described secondary inner side of oil sealing fits with the outer circumferential of piston rod.
This oil sealing dustproof construction includes main oil sealing, secondary oil sealing and dust cover, and dust cover plays dust-proof and sediment prevention effect,
Even if paddling in the chassis of automobile during traveling, the silt in water passes through dust cover, but due to the existence of secondary oil sealing, secondary oil sealing also rises
To dust-proof and sediment prevention effect, secondary oil sealing stops that silt enters in main oil sealing, by dust cover with secondary oil sealing to main oil sealing
Duplicate protection, make main oil sealing to damage, the fluid of vibroshock will not leak, and the service life of vibroshock is long.
In the oil sealing dustproof construction of above-mentioned a kind of vibroshock, described secondary oil sealing is connected with dust cover tight fit.Close-fitting
Close and be connected, be connected convenient, simple in construction.
In the oil sealing dustproof construction of above-mentioned a kind of vibroshock, metallic framework that described secondary oil sealing includes being positioned at inner side and
Being positioned at the rubber sealing boot in outside, the side that described rubber sealing boot and dust cover fit has the anti-slip part of concave-convex surface.
Metallic framework plays the effect of support, and rubber sealing boot plays the effect of sealing, and the setting of anti-slip part makes rubber sealing boot with anti-
It is more tight that dust hood is fitted, and the firmness simultaneously making secondary oil sealing install is high, and pair oil sealing will not fall after being fixed on installation cavity
Go out, make the vibroshock will not leakage of oil.
In the oil sealing dustproof construction of above-mentioned a kind of vibroshock, between described main oil sealing and secondary oil sealing, there is gap.Between
Can fill lubricating oil at gap, piston rod is played the effect of lubrication by lubricating oil.
In the oil sealing dustproof construction of above-mentioned a kind of vibroshock, described dust cover is by POM material or elastomeric material system
Become.POM material is match Steel material, alleviates the weight of dust cover.
Compared with prior art, the oil sealing dustproof construction of the vibroshock that this utility model provides is by arranging dust cover and pair
Oil sealing, dust cover and secondary oil sealing all play air-prevention, the dust-proof and effect of sediment prevention, dust cover and secondary oil sealing and play main oil sealing
Dual protective effect, makes silt etc. will not enter at main oil sealing, and main oil sealing will not damage, and the fluid of vibroshock will not be let out
Leakage, the service life of vibroshock is long.
