Stress caused by caused vibrations in operation process, but the abrasion of rubber layer can be bigger so that rubber layer is frequently changed,
It is very inconvenient.
Utility model content
The technical problems to be solved in the utility model is to overcome the rubber layer inside existing elastic locating sleeve over time can
Produce the problem of larger abrasion needs frequently to change, there is provided a kind of rail vehicle truck elastic locating sleeve.
In order to solve the above-mentioned technical problem, the utility model provides following technical scheme：
The utility model provides a kind of rail vehicle truck elastic locating sleeve, including elastic locating sleeve overcoat, rubber
Layer, elastic locating sleeve inner sleeve and reinforcement, it is sequentially arranged with the elastic locating sleeve inner sleeve, the rubber layer and institute from inside to outside
State elastic locating sleeve overcoat, the rubber sulphur that the elastic locating sleeve inner sleeve and the elastic locating sleeve overcoat pass through the rubber layer
It is integral to change consolidation, the inside of the rubber layer is provided with the reinforcement.
As a kind of optimal technical scheme of the present utility model, the flexibly positioned overcoat is that outer layer is made by metal material
Rubber layer contact portion is the shape and structure on inclined-plane.
As a kind of optimal technical scheme of the present utility model, described elastic locating sleeve overcoat of metal material by being made up
's.
As a kind of optimal technical scheme of the present utility model, the reinforcement is some groups, some groups of reinforcements
It is uniformly distributed in inside the rubber layer.
The beneficial effect that the utility model is reached is：The elastic locating sleeve is strengthened by being provided with the inside of rubber layer
Muscle so that rubber layer increase the intensity of product and it is rigid while, to save quantity of plastics, mitigate weight, reduce its cost,
So that the service life of rubber layer is increased.
Brief description of the drawings
Accompanying drawing is used for providing further understanding to of the present utility model, and a part for constitution instruction, with this practicality
New embodiment is used to explain the utility model together, does not form to limitation of the present utility model.In the accompanying drawings：
Fig. 1 is structural representation of the present utility model；
In figure：1st, elastic locating sleeve overcoat；2nd, rubber layer；3rd, elastic locating sleeve inner sleeve；4th, reinforcement.
Embodiment
Preferred embodiment of the present utility model is illustrated below in conjunction with accompanying drawing, it will be appreciated that described herein excellent
Select embodiment to be merely to illustrate and explain the utility model, be not used to limit the utility model.
Embodiment 1
As shown in figure 1, the utility model provides a kind of rail vehicle truck elastic locating sleeve, including elastic locating sleeve
Overcoat 1, rubber layer 2, elastic locating sleeve inner sleeve 3 and reinforcement 4, it is sequentially arranged with elastic locating sleeve inner sleeve 3, rubber from inside to outside
The vulcanization of rubber that glue-line 2 and elastic locating sleeve overcoat 1, elastic locating sleeve inner sleeve 3 and elastic locating sleeve overcoat 1 pass through rubber layer 2
Consolidation is integral, and the inside of rubber layer 2 is provided with reinforcement 4, and the elastic locating sleeve in the inside of rubber layer 2 by being provided with reinforcement
4 so that rubber layer 2 increase the intensity of product and it is rigid while, to save quantity of plastics, mitigate weight, reduce its cost,
So that the service life of rubber layer 2 is increased.
Flexibly positioned overcoat 1 is that the shape and structure that outer layer rubber layer contact portion is inclined-plane is made by metal material.Elasticity
Positioning sleeve overcoat 1 is made of metal material.Reinforcement 4 is some groups, and some groups of reinforcements 4 are uniformly distributed in rubber layer 2
Inside, reinforcement 4 have under conditions of product wall thickness is not increased, and increase the intensity and rigidity of product, to save quantity of plastics,
Mitigate weight, the advantages of reducing cost, multigroup reinforcement 4 can carry out certain booster action to rubber layer 2, avoid rubber
The defects of layer 2 needs repeatedly to be changed.
The device is a kind of rail vehicle truck elastic locating sleeve, when needing to use the elastic locating sleeve, elasticity
Positioning sleeve overcoat 1 and elastic locating sleeve 3 consolidate integral, the reinforcement 4 inside rubber layer 2 by the vulcanization of rubber of rubber layer 2
Fixed protective effect can be played to rubber layer 2.
The elastic locating sleeve in the inside of rubber layer by being provided with reinforcement so that rubber layer increase product intensity and
While rigid, to save quantity of plastics, mitigate weight, reduce its cost so that the service life of rubber layer is increased.
Finally it should be noted that：Preferred embodiment of the present utility model is the foregoing is only, is not limited to this
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
For, it can still modify to the technical scheme described in foregoing embodiments, or to which part technical characteristic
Carry out equivalent substitution.All any modification, equivalent substitution and improvements within the spirit and principles of the utility model, made etc.,
It should be included within the scope of protection of the utility model.
