The first side plate 41 and the first vertical plate 12 are arranged in a close relationship, and the second side plate 42 and the second vertical plate 13 are arranged in a close relationship. The top plate 50 is connected to the cone sleeve structure 20, and the positioning structure 60 and the connecting structure 70 are both arranged between the top plate 50 and the cone sleeve structure 20. Through the above arrangement, the first cone sleeve 21, the second cone sleeve 22, the first buffer 31, the second buffer 32, the third buffer 33, the first side plate 41 and the second side plate 42 are connected as a whole, so that the first buffer 31, the second buffer 32 and the third buffer 33 jointly bear the vertical force, reduce the stress of the first buffer 31, the second buffer 32 and the third buffer 33 under the action of the external load, that is, achieve the purpose of small creep, small permanent deformation of the side bearing device and improve the life of the side bearing. In this way, when the side bearing device is subjected to a vertical force, the first buffer 31, the second buffer 32 and the third buffer 33 can decompose the vertical force into a vertical compression force and a longitudinal shear force, provide a large vertical deflection through the shear deformation of the first buffer 31, the second buffer 32 and the third buffer 33, provide longitudinal stiffness through the compression deformation of the first buffer 31, the second buffer 32 and the third buffer 33, and reduce the creep of the first buffer 31, the second buffer 32 and the third buffer 33. At the same time, under the action of the positioning structure 60, the top plate 50 and the cone sleeve structure 20 are positioned, and the positioned top plate 50 and the cone sleeve structure 20 make it easier to connect the connection structure 70, and under the action of the positioning structure 60 and the connection structure 70, the top plate 50 and the cone sleeve structure 20 have better stability and are not easy to separate. Therefore, the technical solution of this embodiment effectively solves the problem in the related art that the top plate of the elastic side bearing is easily separated from the rubber body, which affects the use effect of the elastic side bearing.

[0031] Specifically, in this embodiment, the first buffer 31, the second buffer 32 and the third buffer 33 are all rubber parts. The first buffer 31 is vulcanized and connected between the first tapered sleeve 21 and the second tapered sleeve 22, the second buffer 32 is vulcanized and connected between the second tapered sleeve 22 and the first side plate 41, and the third buffer 33 is vulcanized and connected between the second tapered sleeve 22 and the second side plate 42.

And when expanding outwards, the load can be transmitted to the side bearing seat 10.

[0033] The rubber material properties of the rubber parts of this embodiment, such as hardness, tensile strength, elongation at break, permanent deformation, ozone aging resistance, UV aging resistance, etc., are improved compared to the rubber used in the existing elastic side bearings to meet the need for long life. Compared with the existing rubber material properties, the hardness value is increased by about 20%, the tensile strength is increased by about 33%, new ozone aging resistance and UV aging resistance test requirements are added, and the vertical fatigue test, longitudinal fatigue test and enhanced vertical test times are doubled.

[0034] It should be noted that the first conical sleeve 21, the second conical sleeve 22, the first buffer 31, the second buffer 32, the third buffer 33, the first side plate 41 and the second side plate 42 are vulcanized together to form a closed and enclosed space, thereby preventing too much of the first buffer 31, the second buffer 32, and the third buffer 33 from being exposed to the atmosphere and eroded by ultraviolet rays, ozone, etc., thereby improving the reliability of the long life of the side bearing device.

[0035] like Figure 2 , Figure 3 as well as Figure 5 As shown, in this embodiment, the positioning structure 60 includes a protrusion 61 and a recess 62, and the protrusion 61 and the recess 62 are interference fit. One of the protrusion 61 and the recess 62 is arranged on the cone sleeve structure 20, and the other of the protrusion 61 and the recess 62 is arranged on the top plate 50. The protrusion 61 and the recess 62 are interference fit, so that the initial connection between the cone sleeve structure 20 and the top plate 50 can be achieved, and when the cone sleeve structure 20 and the top plate 50 are connected by the connection structure 70, the stability of the cone sleeve structure 20 and the top plate 50 can be improved. At the same time, the structure of the protrusion 61 and the recess 62 is simple and easy to process.

[0036] like Figure 2 , Figure 3 as well as Figure 5 As shown, in this embodiment, the second conical sleeve 22 is located outside the first conical sleeve 21, the protrusion 61 is arranged on the top surface of the second conical sleeve 22, and the inner concave portion 62 is arranged on the bottom surface of the top plate 50. The above arrangement makes the arrangement of the protrusion 61 simpler.

[0037] Specifically, in this embodiment, from top to bottom, the cross-sectional area of ​​the first tapered sleeve 21 gradually increases, and the cross-sectional area of ​​the second tapered sleeve 22 gradually decreases.

[0038] like Figure 2 , Figure 3 as well as Figure 5 As shown, in this embodiment, the protrusion 61 includes an annular convex rib, and the inner concave portion 62 includes an annular groove. The annular convex rib and the annular groove are easier to plug and play, thereby reducing the difficulty of assembly.

[0039] like Figure 2 , Figure 3 as well as Figure 5 As shown, in this embodiment, the connection structure 70 includes a plurality of fasteners, which are connected between the top plate 50 and the second conical sleeve 22, and are arranged around the periphery of the positioning structure 60. The arrangement of the plurality of fasteners can ensure the stability of the connection.

[0040] like Figure 2 As shown, in this embodiment, a first chamfered structure 411 is provided at the bottom corner of the side surface of the first side plate 41 facing the first vertical plate 12, and a second chamfered structure 421 is provided at the bottom corner of the side surface of the second side plate 42 facing the second vertical plate 13. Both the first chamfered structure 411 and the second chamfered structure 421 can achieve the function of avoiding, that is, they can avoid the corner in the side bearing seat 10 to prevent interference.

[0041] like Figure 2 and Figure 5 As shown, in this embodiment, the side bearing device further includes a plurality of first pads 81, the thickness of the plurality of first pads 81 is different, and the plurality of first pads 81 are selectively arranged on the bottom plate 11 and support the first side plate 41, the second side plate 42 and the cone sleeve structure 20. The arrangement of the first pads 81 can adjust the height of the side bearing device, thereby being able to adapt to different usage scenarios.

[0042] like Figure 2 and Figure 5 As shown, in this embodiment, the side bearing device further includes a plurality of second pads 82, the thickness of the plurality of second pads 82 is different, and the plurality of second pads 82 are selectively arranged on the bottom surface of the bottom plate 11. The function of the second pads 82 is the same as that of the first pads 81, that is, the height of the side bearing device can also be adjusted.

[0043] like Figure 2 and Figure 5As shown, in this embodiment, a drainage hole 111 is provided on the bottom plate 11, and a through hole 141 is provided inside the boss 14. The provision of the drainage hole 111 can achieve drainage, that is, avoid water accumulation in the side bearing seat 10. Similarly, the through hole 141 can also achieve drainage, avoiding water accumulation in the cone sleeve structure 20.

[0044] like Figure 1 , Figure 2 , Figure 4 as well as Figure 5 As shown, in this embodiment, the side bearing device further includes a first roller structure 90, which is arranged on a side of the first vertical plate 12 away from the second vertical plate 13, and the axis of the first roller structure 90 is perpendicular to the direction from the cone sleeve structure 20 to the first roller structure 90. The first roller structure 90 can realize load bearing. Specifically, as the vertical pressure of the vehicle body increases on the side bearing device, the side bearing device is compressed and deformed downward, generating vertical and longitudinal displacements to bring the first cone sleeve 21, the second cone sleeve 22, the first buffer 31, the second buffer 32, the third buffer 33, the first side plate 41 and the second side plate 42 close to the side and bottom surfaces of the side bearing seat 10, providing the vehicle body with appropriate vertical, longitudinal and transverse three-dimensional stiffness to ensure appropriate rotational moment. When the vehicle passes through a small curve, the vehicle body rolls to a certain extent, and when the distance between the top plate 50 and the first roller structure 90 in the height direction is zero, the first buffer 31, the second buffer 32 and the third buffer 33 no longer continue to deform, and the first roller structure 90 bears the responsibility instead. The structural form of the first roller structure 90 makes it easier for the vehicle body to pass through a small radius curve relative to the bogie, which ensures that the vehicle passes through the curve smoothly and avoids the first buffer 31, the second buffer 32 and the third buffer 33 being crushed due to excessive force.

[0045] In other embodiments, the side bearing device further includes a second roller structure, which is disposed on a side of the second vertical plate 13 away from the first vertical plate 12, and the axis of the second roller structure is perpendicular to the direction from the cone sleeve structure 20 to the first roller structure 90. The function of the second roller structure is the same as that of the first roller structure 90, that is, it ensures that the vehicle passes through the curve smoothly and prevents the first buffer 31, the second buffer 32 and the third buffer 33 from being crushed due to excessive force.

[0046] In this embodiment, the side bearing device also includes a wear plate, which is interference-connected with the top plate 50, that is, the wear plate is provided with a mounting hole, and the top plate 50 is provided with a mounting column, and the mounting column and the mounting hole are interference-fitted.

[0047] Specifically, in order to adapt to different vehicle spacing, deadweight and other requirements, the side bearing device needs to have different stiffness parameters. Under the same side bearing interface size, the side bearing device of this embodiment is easy to design different side bearing stiffnesses by changing the thickness and angle of the cone sleeve structure 20 and the first side plate 41 and the second side plate 42. A top plate 50 is provided on the top surface of the side bearing device. The top plate 50 and the cone sleeve structure 20 are interference fit, and the top plate 50 and the cone sleeve structure 20 are fastened by four countersunk screws. After assembly, the top plate 50 is connected to the wear plate by interference press fitting. The form design of the side bearing device of this embodiment facilitates the daily inspection and maintenance of the cone sleeve structure 20, the top plate 50 and the wear plate components. In addition, a traceable QR code mark is provided on the cone sleeve structure 20 to achieve rapid tracing of product model, name, specification, batch, production date, etc., which is convenient for inspection and quality tracing.

[0048] According to another aspect of the present application, a bogie is provided. The bogie of this embodiment includes a side bearing device, and the side bearing device is the above-mentioned side bearing device. The above-mentioned side bearing device can ensure the stability of the connection between the top plate and the cone sleeve structure, and can achieve small creep and small permanent deformation of the side bearing device and improve the side bearing life. Therefore, the bogie with the above-mentioned side bearing device also has the above-mentioned advantages.

[0049] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present utility model; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0050] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0051] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.
