Description
Technical field
The present invention relates to a kind of vibroshock, and in particular to a kind of rail locomotive vehicle oil-pressure damper, more particularly to one
Plant high speed motor car oil pressure air-bag shock absorber.
Background technology
On current rail vehicle, i.e., the vibration damping of railway, urban light rail, subway, the locomotive of high speed motor car and vehicle or keep away
Shake the liquid of widely used liquid flow path direction alternation（Oil）Pressure damper, but what currently used vibroshock was arranged in oil storage intracavity
Airbag apparatus are two or more sets circumferentially uniform devices being made up of double-layer rubber capsule, intracapsular inflation, are stored up outside capsule
Oil, although can reach and oil and air are separated by air bag, it is to avoid the emulsion that oil gas blending is produced, but this kind of structure
Airbag apparatus use double-layer rubber material, and in shoe cream room, rubber is taken up space too big so that gas storage efficiency is too low.
Another cylindric airbag apparatus, cyst membrane employ monofilm, relative to the former double-layer air bag device, account for
With small volume, gas storage naturally can be more, but the airbag apparatus of single layer structure are taken up space for as far as possible many storage gas
It is larger, airbag apparatus is contacted with oil drum, in vibroshock actual moving process, it is impossible to so that fluid is timely returned
Stream, causes oil-pressure damper indicator card deformity occur；Its gas storage sealing device by interior cylinder assembly, cyst membrane, air bag base device, three kinds
Part apparatus realize air seal jointly, and the technological requirement to realizing sealing is higher, somewhat misoperation, it is possible to make to bring about the desired sensation
Body is leaked, and does not reach gas storage effect；Cyst membrane device still uses elastomeric material, and the space for taking shoe cream room is relatively large, gas storage effect
Rate is still very low.When cylindric cyst membrane device causes to need to arrange inside vibroshock other structures, possess limitation, from existing
The experimental performance of vibroshock judges that all vibroshock work are not fully satisfied with the oil storage of existing vibroshock, plenum space
Require.
The content of the invention
In order to solve the above problems, the invention provides a kind of rail locomotive vehicle oil pressure air-bag shock absorber, including subtracting
Shake device body, and airbag apparatus, piston apparatus, interior cylinder assembly, oil storage cylinder assembly, the piston are provided with the damper main body
Device is located at the middle part of absorber main body, and the interior cylinder assembly is arranged at the outside of the piston apparatus, and fills with the piston
Put to form interior oil pocket, the oil storage cylinder assembly is arranged at the outside of the interior cylinder assembly and forms outer oil storage with the interior cylinder assembly
Chamber, the airbag apparatus are arranged in the outer shoe cream room；The airbag apparatus are linearly arranged in multiple row by several ballonets
Form, the size according to outer shoe cream room is added to ballonet in outer shoe cream room, in oil pressure air-bag shock absorber running,
There are arbitrarily small airbag fails to will not affect that the normal use of other ballonets, so as to ensure the stability of vibroshock operation.
Further, the ballonet is a kind of enclosed square plastic bag film, belongs to monofilm setting,
The cavity at middle part is used for storing gas.
Preferably, the length dimension of the square plastic bag film is 60mm, and width dimensions are 60mm.
Further, the ballonet is a kind of enclosed cylindric plastic film bag, belongs to monofilm setting, middle part
Cavity be used for store gas.
Preferably, the length dimension of the cylindric plastic film bag is 60mm, and diameter dimension is 4mm.
Further, Oil Guide pipe device, the oil guide pipe are additionally provided with the interior cylinder assembly and the oil storage cylinder assembly
Airbag apparatus are provided with around device.
Further, composite of the material of the airbag apparatus for PE+PA, with good heat-resisting, cold-resistant, wear-resisting
Performance.
Further, the ballonet is made up of elastomeric material, needs by ballonet stream to vibroshock bottom when there is fluid
During portion, between single ballonet, there is certain gap, fluid will be flowed out from the middle of ballonet；When no fluid is from ballonet
During middle outflow, will be in the state of sealing between single ballonet.
A kind of advantage of rail locomotive vehicle oil pressure air-bag shock absorber of the present invention is：
1st, the material adopted by the airbag apparatus of a kind of rail locomotive vehicle oil pressure air-bag shock absorber of the invention itself is shared
Volume relative to the small volume shared by rubber pneumatic bag device, therefore the gas that may store inside oil-pressure damper is more
It is many.
2nd, airbag apparatus of a kind of rail locomotive vehicle of the invention with oil pressure air-bag shock absorber, single ballonet size are big
It is little for 60mm × 60mm or 4mm × 60mm, it is even if increasing Oil Guide pipe device in the middle of oil storage cylinder assembly and interior cylinder assembly, single
Individual ballonet still can be added in shoe cream room one by one, so as to not affect the setting of Oil Guide pipe device.
3rd, a kind of rail locomotive vehicle of the invention is relative with the diameter of piston rod in piston apparatus in oil pressure air-bag shock absorber
Diameter of piston rod used in prior art is big, is just because having used less ballonet, increased oil guide pipe dress
Oil-gas Separation can also be realized after putting.
4th, a kind of rail locomotive vehicle oil pressure air-bag shock absorber of the invention, works as in later stage oil-pressure damper running
In, airbag apparatus are formed in many linear combinations by several ballonets, even if there is one or two to fail, but do not interfere with gas
The overall normal use of bag apparatus.
