Description
Technical field
It the utility model is related to shock absorber, particularly a kind of vane type liquid suitable for being installed and used on heavy track-laying vehicle
Pressure damper.
Background technology
At present, the vane hydraulic shock absorber installed on heavy track-laying vehicle, all it is close using three lips with skeleton
Seal is installed back-to-back, and outside twice are reversely installed, and for dust-proof, inner side is together by compensated cavity work fluid installation, for work
Make the sealing of oil.Because its lubrication and seal condition is good, cost is low, easy to install, in high speed, heavily loaded, large impact dynamic sealing
In be widely used.But this shock absorber, because complicated, internal process pressure is big, and temperature change is big, in heavily loaded favourable opposition
Often occur the failures such as seal damage, oil liquid leakage in the environment hit；In addition because rotate element uses Copper alloy material, in cunning
There is certain gap between dynamic bearing and pivoting leaf bobbin, causes hydraulic fluid leak, vibration damping is unstable；Also exist because each blade into
C fonts are contacted with each working oil chamber inwall, are easily worn in long-term work, and damping force is reduced, and influence the normal use of shock absorber
And the life-span.
The content of the invention
The utility model purpose is to provide the vane type liquid that a kind of sealing property is reliable, and shock resistance is strong, and service life is grown
Pressure damper.
The technical solution of the utility model is completed as follows, and it is on the flange port of a shock absorber cylinder body
A cylinder cap is installed with, being rotatably assorted on cylinder cap to cylinder body interior sealing is provided with a leaf with two symmetrical bladings
Bobbin, a torque arm is extended with to side in the outer end of sharf, a dividing plate is installed in cylinder body between two blades, every
The upper linker of plate is fixed between flange and cylinder cap, is respectively provided with two into the working oil chamber on both sides respectively on dividing plate
Orifice valve in opposite direction, by being communicated with hole into non-conterminous working oil chamber in sharf on sharf, in each work
The contact position of oil pocket internal lobe bobbin upper spacer and sharf is respectively fixed with one layer of wear rib, on the dividing plate of each wear rib contact
Elastic force pad is respectively equipped with, a Contraband font wear rib is separately installed with the blade in each working oil chamber, each Contraband font is resistance to
Abrasive stick is made up of two L-shaped bars, and the centre of two is overlapped with zigzag, is installed respectively in each Contraband font wear rib
There is C font steel ring of the opening against sharf, between sharf and dividing plate linkage section and sharf and end cap and cylinder body
A rotation end socket is separately installed between the support level of inner bottom part.
The utility model has good seal performance, and shock resistance is strong, can ensure the continued reliability of work, greatly prolong
The advantages of shock absorber service life.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；Fig. 2 is Fig. 1 A-A cross section structure diagrams；Fig. 3 is Fig. 2 B-B
Cross section structure diagram.
Embodiment
Embodiment is described in detail with reference to accompanying drawing, it is to be installed with one on the flange port 1 of a shock absorber cylinder body 2
Cylinder cap 12, it is rotatably assorted on cylinder cap to cylinder body interior sealing and a sharf 5 with two symmetrical bladings is installed, in blade
The outer end of axle is extended with a torque arm 13 to side, is provided with a dividing plate 8, the top of dividing plate between two blades in cylinder body
Connection end is fixed between flange and cylinder cap, and it is opposite to be respectively provided with into the working oil chamber on both sides both direction respectively on dividing plate
Orifice valve 9, by being communicated with hole 11 into non-conterminous working oil chamber in sharf on sharf, in each working oil chamber
The contact position of sharf upper spacer and sharf is respectively fixed with one layer of wear rib 10, on the dividing plate of each wear rib contact respectively
Provided with elastic force pad 7, a Contraband font wear rib 4 is separately installed with the blade in each working oil chamber, each Contraband font is wear-resisting
Bar is made up of two L-shaped bars, and the centre of two is overlapped with zigzag, is separately installed with each Contraband font wear rib
The C fonts steel ring 3 of the opposite sharf of one opening, between sharf and dividing plate linkage section and in sharf and end cap and cylinder body
A rotation end socket 6 is separately installed between the support level of bottom.When wheel travels along up-and-down road, torque arm band
Movable vane bobbin rotates to an angle, and due to having dividing plate and sharf to be divided into multiple oil pockets in cylinder body, and fluid is incompressible,
Sharf increases away from the oil pocket space of dividing plate turns into low pressure chamber, and the pressure difference between height pumping cavity makes high pressure chest fluid through dividing plate
On orifice valve to low pressure chamber flow, so as to reach the purpose of vibration damping.Contraband font wear rib is set on the blade of sharf, and
Installation C font copper bands in it, elastic force pad and wear rib are set at the telescopic frame back side, wear rib can be made to be adjacent to its institute as far as possible
The working face to be contacted, even if after abrasion, it also can guarantee that wear rib is brought into close contact in working face, so as to ensure that shock absorber is long-term
Stable sealing；Spin axis end socket is set between sharf and cylinder cap and cylinder base between dividing plate, realizes working oil
The sealing and barotolerance of chamber.
