referring to fig. 1, 2 and 3, the present embodiment provides a ball and cone combined spring 100 that can be used on a railway vehicle bogie to facilitate damping. The ball-cone combined spring 100 mainly includes a first elastic body 110, a second elastic body 120, an intermediate connecting body 130, a first mounting seat 140, and a second mounting seat 150. The first mounting seat 140 and the second mounting seat 150 are arranged at an interval, and the first elastic body 110, the second elastic body 120 and the intermediate connecting body 130 are arranged between the first mounting seat 140 and the second mounting seat 150; the upper portion of the first elastic body 110 is connected to the lower portion of the first mounting seat 140, the lower portion of the first elastic body 110 is connected to the second elastic body 120 via the intermediate connecting body 130, and the second elastic body 120 is connected to the second mounting seat 150.
With continued reference to fig. 1 and 3, the first mounting base 140 includes a first mounting plate 142 and a mounting portion 144, the mounting portion 144 is a protrusion disposed at a lower portion of the first mounting plate 142, and a groove is disposed on the mounting portion 144, and an inner surface of the groove is a portion of the spherical surface. The first mounting plate 142 is further provided with a plurality of bolt holes for connecting with the components on the upper portion of the rotating frame.
Referring to fig. 1 and 4, the first elastic body 110 is a portion of a spherical shell, and corresponds to a shape cut along a plane perpendicular to a diameter direction of the spherical shell. The upper surface of the first elastic body 110 is a convex curved surface, and the lower surface is a concave curved surface, and for convenience of description, the upper surface is named as a first curved surface 111, and the lower surface is named as a second curved surface 112. The first curved surface 111 is used to connect with the groove on the first mounting seat 140, and the second curved surface 112 is used to connect with the intermediate connecting body 130. The first elastic body 110 is a laminated structure of a rubber layer 113 and a metal sheet 114, that is, the first elastic body 110 comprises a plurality of rubber layers 113, the metal sheet 114 is arranged between adjacent rubber layers 113, and the rubber layers 113 and the metal sheet 114 are vulcanized and connected into a whole. On the section where the rotation axis of the first elastic body 110 is located, the rubber layer 113 is in a sector ring shape, and the metal sheet 114 is in a circular arc shape.
With continued reference to FIG. 2, the intermediate connecting body 130 is a solid of revolution component made of metal material, and includes a spherical connecting portion 132 and a conical connecting portion 131 connected to each other, and the spherical connecting portion 132 is disposed above the conical connecting portion 131. The spherical connecting portion 132 is a portion of a sphere, which corresponds to a portion cut from the sphere in a direction perpendicular to the diameter direction. The spherical portion of the spherical connecting portion 132 is used for vulcanization connection with the second curved surface 112 of the first elastic body 110. The tapered connecting portion 131 includes a large end and a small end, the large end is connected with the spherical connecting portion 132 in a planar manner, and the outer conical surface is used for connecting with the second elastic body 120. In this embodiment, the intermediate connecting body 130 is integrally formed. In other embodiments, to facilitate the manufacturing of the spherical connecting portion 132 and the conical connecting portion 131 separately, the spherical connecting portion 132 and the conical connecting portion 131 may be detachably connected, and specifically, a lower portion of the spherical connecting portion 132 and an upper portion of the conical connecting portion 131 are both provided with flanges, and the spherical connecting portion 132 and the conical connecting portion 131 are connected by the flanges. Alternatively, the spherical connecting portion 132 and the tapered connecting portion 131 are separately machined and then connected by welding. In order to reduce the weight of the intermediate connecting body 130, a blind hole is further provided on the lower end surface of the tapered connecting portion 131.
The second elastic body 120 is frustum-shaped as a whole, and the large end thereof is arranged close to the first mounting seat 140 and the small end thereof is arranged close to the second mounting seat 150; the above-described design enables the second elastic body 120 to be mounted in the bell-mouth-shaped mounting tube 154 on the second mount 150, so that the mounting tube 154 can receive the pressure from the second elastic body 120. Specifically, the second elastic body 120 is a nested structure of a conical rubber cylinder 121 and a conical metal cylinder 122; the tapered rubber tube 121 and the tapered metal tube 122 are each formed in a bell mouth shape with an opening facing upward. The adjacent conical rubber cylinder 121 and the conical metal cylinder 122 are connected in a vulcanization manner. The second elastic body 120 is provided with a conical mounting hole, the axis of the conical mounting hole coincides with the axis of the second elastic body 120, and the conical mounting hole is used for being matched and connected with the outer conical surface of the conical connecting portion 131.
The second mounting seat 150 comprises a mounting cylinder 154 and a second mounting plate 152, and the mounting cylinder 154 is connected with the second mounting plate 152; the second mounting plate 152 and the first mounting plate 142 are arranged at an interval, and the mounting cylinder 154 is overall in a bell mouth shape, that is, the aperture of the mounting hole at the end close to the second baffle is smaller than that at the end far away from the second baffle. The outer wall of the second elastomer 120 is vulcanised to the inner wall of the mounting cylinder 154. Because the mounting tube 154 is in the shape of a bell mouth, the mounting tube 154 can bear the pressure from the second elastic body 120 in the vertical direction and can also bear the force generated by the torsional oscillation of the second elastic body 120. After the second elastic body 120 is connected with the second mounting seat 150, a buffer gap is left between the bottom of the second elastic body and the second mounting plate 152, so that a deformation space is left for the second elastic body 120, and the vibration damping performance of the second elastic body 120 is improved. In order to prevent the deformation of the second elastic body 120 from being affected by the sealing of the deformation space, a through hole is formed in the middle of the second mounting plate 152. In addition, the second mounting plate 152 is provided with a plurality of bolt holes for connection with a lower part of the bogie.
The ball cone combined spring 100 provided by the embodiment has the following beneficial effects:
the common damping spring applied to the railway vehicle bogie at present can only absorb vertical, transverse, longitudinal and other vibration forces generally; on the other hand, the railway vehicle bogie generally generates vibration force in the rotating and swinging directions, and other suspensions (such as air springs) are generally required to be mounted for absorbing the vibration force in the rotating and swinging directions. This results in a relatively complex and large sized bogie system and a relatively high maintenance cost for the entire system. The ball-cone combined spring 100 provided by the embodiment has a simple overall structure, and can simultaneously bear acting forces in vertical, transverse, longitudinal, rotational and swinging directions; two sets of independent damping springs are not needed for buffering and absorbing vibration; this directly simplifies the entire bogie system, reducing overall size and weight while ensuring a shock absorbing effect.
It should be noted that the terms of orientation such as "upper", "lower", "vertical" or "horizontal" are used in this disclosure for convenience of description, and are used as references to the drawings, and are not intended to limit the installation orientation of the corresponding parts. In addition, the ball-cone combined spring 100 can be used not only on a railway vehicle bogie, but also in other devices requiring vibration damping.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
