Abstract
The utility model discloses an elastic positioning sleeve for railway passenger train and aims to provide an improved elastic positioning sleeve for railway passenger train. The utility model overcomes the defects that stretching stress exists in the elastic positioning sleeve; rubber can be separated from the inner and outer metal sleeves easily in prior art so that the service life of elastic positioning sleeve and the vehicle running state are improved. The elastic positioning sleeve for railway passenger train comprises an outer sleeve, an inner sleeve and a rubber layer, and is characterized in that the rubber layer is integrated with the inner sleeve into a whole through vulcanization and is pressed into the outer sleeve. The elastic positioning sleeve for railway passenger train is applicable to elastic positioning sleeve of railway passenger train.
Description
Technical field
The utility model relates to a kind of elastic locating sleeve, relates in particular to a kind of improved railroad coach vehicle elastic locating sleeve.
Background technology
On the existing railroad coach bogie of car, all generally adopt elastic locating sleeve, realize the elasticity location between draw gear and the framework, and realize flexibly connecting and transmitting operating tractive force, braking force and absorb the vibration that passes to car body by bogie truck, to improve the riding quality of passenger vehicle vehicle.
The elastic locating sleeve that adopts on the present passenger car bogie, owing to be that overcoat and interior cover directly sulfide by rubber, after rubber shrinks, bigger drawing stress is arranged between rubber layer and the metallic sheath, product breakage is many in real-world operation, and service life is short, and to be this kind structure exist radial drawing stress to its reason when big displacement, be easy to produce rubber and the metal inner and outer cover is peeled off, thereby influence its service life.
Summary of the invention
The purpose of this utility model is to provide a kind of improved railroad coach vehicle elastic locating sleeve, in order to eliminate drawing stress that present elastic locating sleeve exists, easily to produce rubber and metal inner and outer cover and shortcoming such as peel off.
For achieving the above object, technical solution of the present utility model is: for the elastic locating sleeve that comprises overcoat, interior cover and rubber layer, with rubber layer and interior cover sulfuration (or claiming vulcanization of rubber body) in aggregates and be pressed in the overcoat, this vulcanization of rubber body by radial compression 1-5mm, the radial compression amount of this vulcanization of rubber body and rubber hardness can be adjusted with the technical parameter of elastic locating sleeve.
The utility model comprises overcoat, interior cover and rubber layer, it is characterized in that: described rubber layer 3 vulcanizes in aggregates with interior cover 2 and is pressed in the overcoat 1.
The utility model and existing elastic locating sleeve are relatively, its advantage is: cover is with rubber layer sulfuration (or claiming vulcanization of rubber body) in aggregates and be pressed in the overcoat in using instead, this vulcanization of rubber body by radial compression 1-5mm, prestress radially is being provided, thereby particularly when big displacement radially, drawing stress can not occur and cause endurance failure, avoid rubber and metal inner and outer cover drawback such as to peel off, prolonged the service life of product, improved the riding quality of passenger vehicle vehicle.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Among the figure: cover in the 1-overcoat, 2-, 3-rubber layer.
The specific embodiment
Below in conjunction with accompanying drawing the utility model and the specific embodiment thereof are described in further detail.
Referring to accompanying drawing, the utility model comprises overcoat, interior cover and rubber layer, it is characterized in that: described rubber layer 3 vulcanizes in aggregates with interior cover 2 and is pressed in the overcoat 1.
Concrete implementation step is: earlier interior cover 2 is placed in the mould, injecting rubber then vulcanizes, make the rubber of injection form rubber layer 3 and form an integral body (vulcanization of rubber body) with interior cover 2, this vulcanization of rubber body squeezes in the overcoat 1, it radially has been compressed 1-5mm, and the radial compression amount of this vulcanization of rubber body and rubber hardness can be adjusted with the technical parameter of elastic locating sleeve, for example: when the operation diametral load is 1 ton hour, hardness is 68, and the radial compression amount is 2mm.
Claims (1)
1, a kind of railroad coach vehicle elastic locating sleeve comprises overcoat, interior cover and rubber layer, it is characterized in that: described rubber layer (3) vulcanizes in aggregates with interior cover (2) and is pressed in the overcoat (1).
