Gap 16 and through-hole 2 15 between 713 and through-hole 2 15 enter eventually into gas chamber 6, during the work time, remain close
In the state that is in contact between envelope block 1 and through-hole 1, there are gaps 16 between sealing block 2 713 and through-hole 2 15, i.e.,
Remain that through-hole 2 15 is in the open state, so that being connected between gas chamber 6 and air flue 2 13, with the change of car body total weight
Change, the gas in gas chamber 6 can be filled with or be discharged from air flue 2 13.In addition, being installed when reversing the present embodiment, i.e., upper elasticity
Link block 1 is connect with bogie, when lower elastic connection block 2 is connect with car body, at this point, during the work time, sealing block 2 713 with
In the state that is in contact between through-hole 2 15, there are gaps between sealing block 1 and through-hole 1, that is, remain through-hole one
14 is in the open state, so that being connected between gas chamber 6 and air flue 1.Therefore, the present embodiment by above-mentioned design so that
In the course of work, there is an air flue to be in connected state with gas chamber always, so that the indoor tolerance of gas can be total with car body
The variation of weight and change, further improve the smooth row of vehicle driving and the comfort of carriage.In addition, the present embodiment passes through
Above-mentioned symmetric design can be installed between car body and bogie rapidly, without should be noted positive and negative position, both improved installation effectiveness or
Increase practicability.
As shown in figure 4, the sealing block 1 and sealing block 2 713 be all provided be set to it is hemispherical, correspondingly, through-hole 1
Spherical surface is also respectively provided with into the inner peripheral surface of through-hole 2 15.Setting is in this way convenient for sealing block and through-hole contact sealing.
Hemispherical sealing block 1 and hemispherical sealing block 2 713 can be used metal material and be made, in hemispherical sealing block
1 and hemispherical sealing block 2 713 spherical surface on be additionally provided with one layer of rubber layer 17.
As shown in Figure 6 and Figure 7, there are also sealed grooves 1 on one end of the sealing ring 5, cover 9 at upper conical spring bottom
Step 1 is provided on the lateral surface of one end, by the way that the bottom of upper conical spring is covered 9 one ends and close to upper conical spring bottom set 9
The rubber bodies 10 of one end are inserted into sealed groove 1 together and utilize a side of sealed groove 1 and the step
One 911 are in contact, so that the rubber bodies 10 being inserted into sealed groove 1 to be pressed on to the other side of sealed groove 1
Bian Shang；
Identical reason, there are also sealed grooves two in the other end of the sealing ring, cover one end at inferior pyramidal spring bottom
Step two is provided on the lateral surface in portion, by the way that the bottom of inferior pyramidal spring is covered one end and covers the rubber of one end close to inferior pyramidal spring bottom
Colloid is inserted into sealed groove two together and is in contact using a side of sealed groove two with the step two, thus will insertion
Rubber bodies in sealed groove two are pressed on (not shown) on the other side side of sealed groove two.The present embodiment is by setting
Above-mentioned sealing structure is set, to ensure that the air-tightness of gas chamber.
As shown in fig. 6, the upper conical spring 3 bottom set 9 and horizontal line between angle theta and inferior pyramidal spring bottom set with
Angle between horizontal line is 70-90 degree.It is arranged to such angle, extruding when can further increase sealing to rubber bodies
Power, so that sealing performance is more preferable.
As shown in fig. 7, in addition the vertical height of a side of the sealed groove 1 is less than sealed groove 1
The vertical height of a side；The vertical height of a side of sealed groove two is less than the vertical of the other side side of sealed groove two
Highly.Setting easily facilitates the compression to rubber bodies in this way, guarantees sealing performance.
There are gaps between the top surface on the other side side of step 1 and sealed groove 1 in upper conical spring 3
16；Also there are gaps between the top surface on the other side side of the step two in inferior pyramidal spring and sealed groove two.At work, it needs
Vertical deviation is realized using upper and lower volute spring, the present embodiment is by the way that in above-mentioned position, there are gaps, so as to bore above and below
Shape spring reduces the impact force between bottom set and sealing ring when realizing vertical deviation, avoid damaging, further prolong the service life.
Embodiment 2: as shown in Figure 8 and Figure 9, compared with Example 1, the difference is that: the upper elastic connection block 1 is
Rubber metal pad, including top plate 18, bottom plate 19 and the elastic rubber 20 being arranged between the top plate 18 and bottom plate 19, in elastic rubber
One or more layers partition 21 is provided in 20.Through hole, as gas are provided in the middle part of top plate and bottom plate, elastic rubber and partition
Road.The structure of lower elastic connection block is as the structure of upper elastic connection block.The bottom plate 19 of upper elastic connection block 1 with it is upper conical
Spring 3 connects, and the bottom plate 19 of lower elastic connection block 2 is connect with inferior pyramidal spring 4.General bellows type air spring is same using air bag
Shi Shixian vertical deviation and lateral displacement, so after a period of operation, it is easy to shorten the service life of air bag, and this reality
It applies example and lateral displacement is realized using upper and lower rubber metal pad, realize vertical deviation using upper and lower volute spring, thus extend air
The service life of spring reduces maintenance cost.
To sum up, the utility model does not use air bag, but uses and enclose shape between upper conical spring, inferior pyramidal spring and sealing ring
At gas chamber, vehicle driving is improved so as to avoid there is the problems such as air bag is damaged after long-time service using gas chamber substitution air bag
Smooth row and carriage comfort.It is designed by structure, so that during the work time, thering is an air flue to be in always with gas chamber
Connected state further improves vehicle row so that the indoor tolerance of gas can change with the variation of car body total weight
The comfort of the smooth row sailed and carriage.In addition, the utility model is designed by symmetrical structure, it can be installed to car body rapidly and turn
To between frame, without should be noted positive and negative position, installation effectiveness is both improved and having also increased practicability.By the way that sealing structure is arranged, from
And it ensure that the air-tightness of gas chamber.Lateral displacement is realized using upper and lower rubber metal pad, realizes vertical deviation using upper and lower volute spring,
The service life of air spring is thus extended, maintenance cost is reduced.
" multiple " described in above embodiments refer to the quantity of " two or more ".Above embodiments are only for explanation
The utility model is used, rather than limitations of the present invention, and person skilled in the relevant technique is not depart from this practical new
In the case where the spirit and scope of type, it can also make a variety of changes or convert, therefore all equivalent technical solutions also should
Belong to the protection scope of the utility model, the protection scope of the utility model should be limited by each claim.
