DESCRIPTION OF THE EMBODIMENTS
    The present invention will be further clarified on the basis of the following figures and embodiments.
    As shown in Figure 1 and Figure 2, an embodiment of the combined air spring system in the present invention includes an upper cover plate 1, an air cushion 2, an upper end plate 3 and a plate lower end 4; the periphery of the upper cover plate 1 is connected to the periphery of the upper end plate 3 via the air cushion 2; an hourglass elastomer in the lower position 5 is connected between the upper end plate 3 and the lower end plate 4; a pressure plate 7 is installed at the bottom of the upper cover plate 1; an elastomer in the upper position 6 is connected between the upper cover plate 1 and the pressure plate 7; a limitation plate 71 is arranged at the bottom of the pressure plate 7; a limiting groove 31 is formed in the upper face of the upper end plate 3; the limitation plate 71 is located in the limitation groove 31 in the deflated state. In this structure, hourglass elastomers in the lower position 5 and elastomers in the upper position 6 which are of a divided type structure form a structure in series which increases the elevation of the elastomer between the upper cover plate 1 and the lower end plate 4, thereby considerably reducing the vertical rigidity under heavy load of the secondary spring and improving the comfort of the secondary spring at heavy loads; moreover, as the elevation increases, the transverse displacement of the elastomer between the upper cover plate 1 and the lower end plate 4 is also increased; in this structure, the hourglass elastomers in the lower position 5 are completely isolated from the elastomers in the upper position 6 through the upper end plate 3 and the pressure plate 7, so as to avoid the transverse deformation of the secondary spring and to improve the stability of the transverse movement of the secondary spring; in this structure, the upper end plate 3 and the pressure plate 7 are installed without
    -5 damage the hourglass elastomer in the lower position 5 and the elastomer in the upper position 6; the structure is simple; it improves the convenience of installation and guarantees the completeness of the hourglass elastomers in the lower position 5 and the elastomers in the upper position 6; the limitation plate 71 is located in the limitation groove 31 in the deflated state, the movement of the upper cover plate 1 in the transverse direction is restricted and limited, in order to solve the different requirements in terms of limitation interval for the air spring system in the length and width directions of the body in the deflated state.
    In this embodiment, the limiting plate 71 and the limiting groove 31 both comprise a pair of inclined surfaces and a pair of planar surfaces; the flat surfaces are arranged along the length direction of a body, and the inclined surfaces are arranged along the width direction of the body. Such a configuration makes the limitation interval of the bodywork in the direction of the length greater than that of the bodywork in the direction of the width, in order to adapt to the inertia of movement of the bodywork and to prevent movement too much bodywork to the left and right.
    In this embodiment, the lower part of the upper cover plate 1 is provided with a stop plate 11 outside the elastomer in the upper position 6. The stop plate 11 restricts and limits the transverse movement of the elastomer in the upper position 6, in order to prevent transverse deformation.

The stop part 41 guarantees the overall stabilization of the vehicle and does not keep any interference between the body and the bogie at high loads and dynamic loads, etc.
    In this embodiment, the peripheral face of the upper end plate 3 is located outside the hourglass elastomer in the lower position 5. Such a configuration causes the upper end plate 3 to extend fully. to the outside of the hourglass elastomer in the lower position 5, convenient for installation.
    In this embodiment, the lower part of the peripheral face of the plate
    -6 upper cover 1 is provided with a retaining ring 12; one end of the air cushion 2 is attached with the retaining ring 12, and the other end is connected to the upper end plate 3. In this structure, the small opening of the air cushion 2 is connected to self-sealing with bottom end plate 3, to prevent air leakage.
