Description
Technical field
The utility model is related to a kind of air spring seal arrangement.
Background technology
The track traffic of green low-carbon is actively developed in current many countries and regions, and Air spring for rail traffic system is
The important component of train composition, plays support car body, reduces vibration and provides transverse direction and torsional deflection, it is ensured that the fortune of vehicle
Row safety.With the development of track traffic, the condition of track circuit also becomes complicated, the particularly more and more applications of air spring
In low temperature environment, minimum temperature can arrive subzero 50 °, and air spring rubber elasticity traditional under low temperature dies down and shrinks,
Sealability declines, easy gas leakage, and this is proposed to air spring ensures the requirement of air-tightness under low temperature environment.
In the prior art, the Chinese invention patent of Application No. 200810032148.8 discloses son on a kind of air spring
Mouth sealing means and its device, rubber pneumatic bag rim of the mouth is placed in the groove of rim of the mouth, and described rim of the mouth groove is by upper cover plate and friction board
Combination formed, rubber pneumatic bag rim of the mouth is placed in the rim of the mouth groove formed between upper cover plate and friction board, and by upper cover plate with
Laminating compression between friction board forms the sealing in rubber pneumatic bag rim of the mouth.Described rubber pneumatic bag rim of the mouth sealing structure is：Upper
A groove-shaped notch is provided with cover plate, also there is a breach with taper on friction board, there is the groove-shaped notch and friction board of upper cover plate
Breach combine to form a cone-shaped cavity for having openings at one side, upper cover plate is linked together with friction board by fastener.Rubber
Glue air bag rim of the mouth is placed in cone-shaped cavity, and the side of rubber pneumatic bag is drawn by the side openings of cone-shaped cavity, rubber pneumatic bag by
Opening is from extending centrally out.The Chinese invention of Application No. 201610770841.X discloses a kind of air-spring bellows with lid
The sealing device of plate connection, including upper cover plate, outer buckle ring, internal buckle ring, center ring, ring-shaped clip, air bag, center ring mainly play branch
Support is acted on, the wedge shaped face in its outer surface, and the wedge-shaped gradient is α；Ring-shaped clip plays clamping action, the wedge shaped face of its inner surface, wedge shape
The gradient is β, and β=α+k；The outer buckle ring circumferentially arranged plays connection function, and outer buckle ring opens before installing, in annular snap after installation
The lower deformation of hoop constraint is tightened up, and is brought into close contact with air bag and clip inner surface.Above prior art is difficult to solve air under low temperature
The technical problem of the easy gas leakage of spring.
Utility model content
The utility model provides a kind of air spring seal arrangement, can be adapted to low temperature environment operation, meets air spring
Seal request in low temperature environment.
The technical solution of the utility model is：A kind of air spring seal arrangement, including upper cover plate, clasp and air bag, institute
Stating air bag includes rim of the mouth on air bag, and upper cover plate and clasp are connected on air bag at rim of the mouth, and the air spring seal arrangement is also wrapped
Include connecting plate and O-ring seal；The connecting plate is sulfided with rim of the mouth on air bag, connecting plate connection upper cover plate and clasp,
The groove for mounting O-shaped sealing ring, O-ring seal are offered on the upper cover plate or connecting plate of upper cover plate Yu connecting plate joint
In groove.
Groove on the upper cover plate or connecting plate has more than 1, and an O-ring seal is respectively provided with each groove.
The connecting plate, clasp, upper cover plate are connected by screw together.
The upper cover plate and connecting plate are tightly connected by O-ring seal.
The air bag forms an entirety with connecting plate.
The utility model is a kind of Air spring for rail traffic sealing device, solves existing air used for rail vehicle
The problem of easy gas leakage under spring low temperature environment.The utility model is to meet air spring low compared with the advantage of conventional air bellows
Seal request in warm environment, the air-tightness of lower air spring is can ensure that in low temperature environment, is vulcanized by rim of the mouth on air bag
One connecting plate, increases O-ring seal sealing between connecting plate and upper cover plate, and O-ring seal uses encapsulant, by air bag
It is to ensure air-tightness by O-ring seal that the air-tightness in rim of the mouth is cleverly shifted, and designs ingenious, with substantive novelty.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the J partial enlarged drawings in Fig. 1；
Description of reference numerals：Upper cover plate 1, O-ring seal 2, connecting plate 3, clasp 4, air bag 5.
Specific embodiment
As depicted in figs. 1 and 2, the utility model air spring seal arrangement is main by upper cover plate 1, O-ring seal 2, company
Fishplate bar 3, clasp 4, air bag 5, secondary spring, screw etc. are constituted.On air bag rim of the mouth vulcanize a connecting plate, on air bag rim of the mouth with
Connecting plate is sulfided, and makes air bag with connecting plate as an entirety.Slotted on upper cover plate or connecting plate, sealing is put in groove
Material（O-ring seal）, O-ring seal is positioned between upper cover plate and connecting plate.With screw by connecting plate, air bag rim of the mouth, clasp,
