In order to solve the above technical problems, the utility model uses following technical scheme：
A kind of hourglass air spring assembly, including upper cover plate, air bag, upper head plate and bottom plate, outside the upper cover plate
Week is connected by the air bag with upper head plate periphery, and low level hourglass elastomer, institute are connected between the upper head plate and bottom plate
It states and is connected with high-order elastomer at the top of upper head plate.
As being further improved for above-mentioned technical proposal：
The low level hourglass elastomer center is equipped with inner cavity, and the upper head plate bottom centre is equipped with the stop for extending inner cavity
Portion.
The bottom surface that the upper head plate is located at stop portion side is arranged to flat face, and the top surface of upper head plate is by center and outer
Inclined-plane is formed between the flat face of all positions and two flat faces, and the low level of upper head plate top bevel is by the straight of entad
Face.
The outer circumferential surface of the upper head plate is located at the outside of low level hourglass elastomer and high-order elastomer.
The high position elastomeric apex is connected with wearing plate.
The upper cover plate outer circumferential surface bottom is equipped with retaining ring, described air bag one end and retaining ring snapping, the other end with outside upper head plate
Week connection.
Compared with prior art, the utility model has the advantage of：
The hourglass air spring assembly of the utility model, including upper cover plate, air bag, upper head plate and bottom plate, upper cover plate
Periphery be connected by air bag with upper head plate periphery, low level hourglass elastomer, upper head plate are connected between upper head plate and bottom plate
Top is connected with high-order elastomer.In the structure, formed by the low level hourglass elastomer and high-order elastomer of split structure
Cascaded structure adds the elevation of upper head plate top and the bottom elastomer, that is, greatly reduces under heavy loads vertical of secondary spring
Rigidity improves the comfort under heavy loads of secondary spring；In addition, while elevation increase, also increase on upper head plate
The lateral displacement of lower elastomers, the structure is completely separated by low level hourglass elastomer and high-order elastomer by upper head plate, i.e.,
The Cross deformation of secondary spring can be avoided, improves the stability of secondary spring lateral displacement；In the structure, low level hourglass bullet
Property body, high-order elastomer and upper head plate stack gradually, simple in structure, upper head plate will not destroy low level hourglass elastomer when installing
With high-order elastomer, improve the convenience of installation and ensure that the integrality of low level hourglass elastomer and high-order elastomer.

Specific embodiment
The utility model is described in further details below with reference to Figure of description and specific embodiment.
As shown in Figure 1, a kind of embodiment of the utility model hourglass air spring assembly, including upper cover plate 1, air bag 2,
Upper head plate 3 and bottom plate 4, the periphery of upper cover plate 1 is connected by air bag 2 with 3 periphery of upper head plate, between upper head plate 3 and bottom plate 4
Low level hourglass elastomer 5 is connected with, 3 top of upper head plate is connected with high-order elastomer 6.In the structure, pass through split structure
Low level hourglass elastomer 5 and high-order elastomer 6 form cascaded structure, add the elevation of 3 top and the bottom elastomer of upper head plate, i.e., big
The big vertical stiffness under heavy loads for reducing secondary spring improves the comfort under heavy loads of secondary spring；In addition,
While elevation increase, the lateral displacement of 3 top and the bottom elastomer of upper head plate is also increased, the structure is by upper head plate 3 by low level
Hourglass elastomer 5 and high-order elastomer 6 are completely separated, can avoid the Cross deformation of secondary spring, improve secondary spring
The stability of lateral displacement；In the structure, low level hourglass elastomer 5, upper head plate 3 and high-order elastomer 6 stack gradually, structure
Simply, low level hourglass elastomer 5 and high-order elastomer 6 will not be destroyed when upper head plate 3 is installed, improves convenience and the guarantor of installation
The integrality of low level hourglass elastomer 5 and high-order elastomer 6 is demonstrate,proved.
In the present embodiment, 5 center of low level hourglass elastomer is equipped with inner cavity 51, and 3 bottom centre of upper head plate is equipped with and extends inner cavity
51 stop portion 31.The stop portion 31 ensure that the overall deflection of vehicle, it is ensured that when top load and dynamic load, car body
It is not interfered with bogie.
In the present embodiment, the bottom surface that upper head plate 3 is located at 31 side of stop portion is arranged to flat face, the top surface of upper head plate 3 by
Inclined-plane is formed between center and the flat face and two flat faces of circumferential position, and the low level of 3 top bevel of upper head plate is close
The flat face of center.In the structure, the setting on inclined-plane causes secondary spring, and in lateral displacement, opposite inclined-plane can be to it
It is constrained, prevents its Cross deformation；And the setting of flat face can guarantee low level hourglass elastomer 5 and high-order elastomer up and down
The uniformity of 6 vertical stress.
In the present embodiment, the outer circumferential surface of upper head plate 3 is located at the outside of low level hourglass elastomer 5 and high-order elastomer 6.So
It sets so that the whole outside for extending to low level hourglass elastomer 5 and high-order elastomer 6 of upper head plate 3 is easily installed.
In the present embodiment, high-order 6 top of elastomer is connected with wearing plate 7.The wearing plate 7 mainly avoids high-order elastomer
6 losses.
In the present embodiment, 1 outer circumferential surface bottom of upper cover plate is equipped with retaining ring 11,2 one end of air bag and 11 snapping of retaining ring, the other end with
3 periphery of upper head plate connects.In the structure, upper head plate 3 is protected with 2 small rim of the mouth connecting portion of air bag using the vulcanization of rubber, mitigates gas
The abrasion condition of 2 small rim of the mouth of capsule under heavy loads can improve the service life of air bag 2 and secondary spring.
