Description
Technical field
Automobile absorber field is the utility model is related to, more particularly to a kind of high-comfort damper single cylinder guider.
Background technology
Automobile is when by uneven road surface, although the shock-absorbing spring in suspension system can filter the vibrations on road surface, bullet
Spring itself also has reciprocating motion, and damper is exactly back and forth to be jumped for suppressing this spring.The structure of damper is band
Have in the piston rod insertion tube of piston, full of oil in cylinder.There is throttle orifice on piston so that the two parts separated by piston are empty
Between in oil can complement each other.The operation principle of damper is to work as phase occurred by vibrations between vehicle frame and vehicle bridge or vehicle body and vehicle bridge
During to motion, the piston in damper moves up and down, and the fluid in snubber cavity just repeatedly passes through different holes from a chamber
Clearance flow enters another intracavitary, and the now friction between hole wall and fluid and the intermolecular interior friction of fluid form damping force to vibrations,
Thump energy is converted into fluid heat energy, then be dispersed into by absorber in air.Guider is the weight in damper
One of part is wanted, its motion to piston rod in damper plays good guide effect, ensures piston in the process of running flat
It is pliable, while connected working cylinder with oil storage cylinder by the oilhole of guider during piston movement.
In actual use, due to much time using, lubricating oil can be remained in piston rod surface, causes damper
The increase of oil sealing pressure, while be piston rod surface lubricating oil film it is uneven, damper service life is short, a kind of existing band oil
The guider of oil-scraping ring, provided with the oil-scraping ring being slidably matched with piston rod, oil-scraping ring side is by being located in guide way mounting hole
Bushing it is spacing in mounting hole, mounting hole side, which is provided with, to be used for the oil that scrapes oil-scraping ring and is directed to the fuel-displaced of guider side
Passage, but the guider still suffers from following shortcoming：Bushing is easily driven and skids off guider, causes the guiding of guider to fail,
And cause damper to shake, and the lubricating oil on piston rod is all directed to guiding when piston rod moves back and forth by oil discharge passage
The side of device, cause the oil pressure of guider both sides uneven, cause oil sealing pressure to increase, cause damper operator unstable, influence
The comfortableness of damper.
The content of the invention
Technical problem to be solved in the utility model is：There is provided a kind of bushing be not easy abjection and guider both sides oil pressure it is equal
High-comfort damper single cylinder guider even, comfortableness is high.
The technical scheme in the invention for solving the above technical problem is：A kind of high-comfort damper single cylinder is oriented to
Device, including guider, the guider center are provided with mounting hole, bushing, the end face of the mounting hole are provided with the mounting hole
The oil-scraping ring for being used for being slidably matched with piston rod is provided between bushing, footpath is provided between the oil-scraping ring periphery wall and mounting hole
To gap, be provided with axial gap between the oil-scraping ring and bushing, the end face of the mounting hole be provided be used for by fluid export to
The first of guider side goes out oil groove, and the hole wall of the mounting hole, which is provided with, to be used for the jump ring of bushing axial limiting, the installation
The hole wall in hole is circumferentially distributed multiple axially disposed gaps for being used to connect oil-scraping ring and the second of guider opposite side
Go out oil groove.
Compared with prior art, the utility model has the advantage of：Bushing one end is another by oil-scraping ring axial limiting, bushing
One end is spacing by jump ring, avoids bushing from deviating from guider under the reciprocating of piston rod, when piston rod is movable vertically upward
When, oil-scraping ring is driven the upper surface with mounting hole to lean vertically upward, and the fluid on piston rod is swept and erected by oil-scraping ring
It is flow to oil groove is gone out along first upwards on the upside of guider, when piston rod is movable vertically downwards, oil-scraping ring is driven by vertically first lower
Offset and examine with the upper surface of bushing, the fluid on piston rod, which is swept by oil-scraping ring and goes out oil groove along second vertically downwards, flow to guiding
On the downside of device, the lubricating oil of guider both sides goes out oil groove and second by first and goes out oil groove connection, and both sides oil pressure is uniform, avoids oil sealing
It is destroyed because pressure is uneven, improves the overall service life of damper.
As it is of the present utility model it is a kind of improve, the guider upper end be provided with vertically to mounting hole orient diameter sequentially
The stepped hole of reduction, by the improvement, in the prior art, projection is provided with the stepped hole of guider end face to mounting hole, held
Easily assemble lubricating oil and cause the lubricating oil of aggregation can not participate in lubrication, influence the guiding of piston rod, stepped hole is arranged to straight
Footpath sequentially reduces so that lubricating oil is all directed to piston rod, ensures the reciprocating lubricity of piston rod.
