Technical field
The utility model relates to a kind of dust guard, specifically a kind of oil-pressure damper dust cover belongs to track
Traffic equipment technical field.
Background technique
When EMU is run, due to the excitation by various factors, between vehicle and track, each vehicle of EMU it
Between will necessarily generate interaction, pass through interaction and generate horizontal and vertical out-of-balance force.In addition in the fabrication process, iron
Rail absolutely straight, absolute rigidity, the wheel of EMU can not be also impossible to be circular ideal.Just because of this out-of-balance force
With foozle, the complicated characteristics of motion can be presented when running along rail for EMU, therefore vibrates and just inevitably generate,
The safety in operation of EMU is had an important influence on.In order to reduce vibration frequency and amplitude, the safety of EMU operation is improved
Property, in EMU oil-pressure damper with more and more extensive, but in air due to damper exposure, the dust in air holds
Easily enter inside damper, will be greatly reduced the service life of damper.
There are mainly two types of dust-tight manners for existing oil-pressure damper, and one is install one on dust cover and oil storage cylinder outer surface
A rubber bellows, for preventing the entrance of dust, but since bellows covers oil storage cylinder most surfaces, it has not been convenient to check
Whether damper there is the phenomenon that oil leak；Another kind be dust cover bottom be arranged sponge friction block, but due to vibration when sponge
Block with oil storage cylinder external wall friction, generates heat always, and the sponge block service life is caused to decline, and dirt exclusion capabilities die-off, therefore now more next
More customer requirement dust guards are built-in or do not use dust guard.
Utility model content
Technical problem to be solved in the utility model is, the shortcomings that for the above prior art, proposes that a kind of oil pressure subtracts
Shake dust plug,, can be perfect under the premise of not influencing to check damper leakage by the way that dirt-proof boot is arranged in dust cover
Blocks dust enters on the piston rod inside damper, improves the service life of damper.
In order to solve the above-mentioned technical problem, the utility model provides a kind of oil-pressure damper dust cover, including damper
Dust cover and built-in dirt-proof boot, the shock absorber dirt shield are socketed on the oil storage cylinder of oil-pressure damper；It is described built-in dust-proof
Set is hollow ring set, and one end of the built-in dirt-proof boot passes through the oil storage cylinder upper end stationary phase of fixed mechanism and oil-pressure damper
Even, the other end of the built-in dirt-proof boot is fixedly linked by the lower end of fixed mechanism and the shock absorber dirt shield.
The utility model further limits technical solution, oil-pressure damper dust cover above-mentioned, the built-in dirt-proof boot
In hollow truncated cone-shaped, the smaller diameter end of the built-in dirt-proof boot is solid by the oil storage cylinder upper end of fixed mechanism and oil-pressure damper
Fixed to be connected, the larger diameter end of the built-in dirt-proof boot is fixedly linked by the lower end of fixed mechanism and the shock absorber dirt shield.
Oil-pressure damper dust cover above-mentioned, the built-in dirt-proof boot are made of natural rubber, built-in dirt-proof boot
With a thickness of 0.5-1.5mm, the tensile elongation of built-in dirt-proof boot can achieve 350%.
Further, the middle section of oil-pressure damper dust cover above-mentioned, the built-in dirt-proof boot is fold ripple
Shape structure；The fixed mechanism is German-style clip.
A kind of oil-pressure damper is equipped with oil-pressure damper dust cover above-mentioned on oil-pressure damper.
The utility model has the beneficial effect that the utility model by the way that dirt-proof boot is built in dust cover and oil storage cylinder
Between, while meeting effectiveness in vibration suppression, it can prevent dust from entering and be attached to piston rod surface inside damper, prevent piston rod
It is scratched when moving up and down, so as to improve the service life of damper.Since built-in dirt-proof boot is made of natural rubber, use
When can have biggish range of stretch, in the stroke range of oil-pressure damper have enough stretching surpluses, be hardly damaged；It adopts
Built-in dirt-proof boot is installed with German-style clip, it is easy for installation, fastness is connected, making for oil-pressure damper dust cover is fully met
With.

Specific embodiment
The utility model is described in further detail below:
Embodiment 1
A kind of oil-pressure damper provided in this embodiment, structure is as depicted in figs. 1 and 2, by piston rod assembly 1, dust cover
2, end-cap assembly 3, built-in dirt-proof boot 4, oil cylinder 5, piston component 6, oil storage cylinder 7 form.Dust cover 2 is connected to piston rod assembly 1
On, oil liquid is full of inside oil cylinder 5, oil cylinder 5 is divided to for upper and lower two chamber by the piston component 3；2/3 oil liquid is filled inside oil storage cylinder 7；When
When Vehicular vibration, piston rod assembly 1 drives piston component 6 to move up and down, and is pushed inside oil cylinder 5 and oil storage cylinder 7 by positive/negative-pressure
