Technical Field

[0001] This utility model relates to the field of rail vehicle technology, and in particular to an integrated shock absorber mounting base and a train bogie. Background Technology

[0002] Shock absorbers are an indispensable component of the suspension system of rail transit vehicles. Typically, in the bogie suspension system of urban, intercity and high-speed trains, not only are secondary vertical hydraulic shock absorbers installed, but anti-hunting hydraulic shock absorbers are also installed to improve the running stability of the vehicle.

[0003] Existing train frames are generally H-shaped structures, with crossbeams connected by steel pipes passing through the side beams. The mounting bases for the secondary vertical hydraulic dampers and anti-hunting hydraulic dampers are separately installed on the frame, fixed to the side beams by welding, and then reinforced with stiffening plates. However, providing separate mounting bases for the secondary vertical hydraulic dampers and anti-hunting hydraulic dampers occupies a large amount of space and limits the space for anti-roll and torsion bars on the side beams, resulting in poor installation reliability.

[0004] Therefore, there is an urgent need for an integrated shock absorber mounting base and train bogie to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an integrated damper mounting base with a compact structure, which realizes the integrated installation of the anti-snaking hydraulic damper and the secondary vertical hydraulic damper, optimizes the installation space, and thus improves the installation reliability of the anti-roll torsion bar.

The supporting part is fixedly connected to the vertical edge, the connecting part is fixedly connected to the side edge, and the fixing part is fixedly connected to the horizontal edge.

[0013] As an optional technical solution, the support part is provided with an abutment part, the longitudinal section of which has an inverted triangular structure, and the abutment part abuts against the fixing plate.

[0014] As an optional technical solution, the fixing plate is welded to the upright plate through the insertion slot.

[0015] As an optional technical solution, the support component is welded to the edge of the upright plate, and the support component is also welded to the fixing plate.

[0035] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0036] like Figures 1 to 3 As shown, this embodiment provides an integrated vibration damper mounting base, which includes a vertical plate 1, a fixed plate 2, and a support assembly. The vertical plate 1 has an insertion slot 11 and a mounting hole 12. The mounting hole 12 is used to install an anti-snake-like hydraulic vibration damper 100. The fixed plate 2 is fixedly inserted into the insertion slot 11 and has a connection hole 21 for installing a secondary vertical hydraulic vibration damper 200. The support assembly includes a first fastening plate 3 and a second fastening plate 4. The first fastening plate 3 and the second fastening plate 4 are located on both sides of the fixed plate 2 and fixedly connected to the edge of the vertical plate 1. The first fastening plate 3 abuts against the first end face of the fixed plate 2, and the second fastening plate 4 abuts against the second end face of the fixed plate 2.

[0037] For example, the anti-snake hydraulic damper 100 is horizontally installed on the side beam 300 of the frame, and the secondary vertical hydraulic damper 200 is vertically installed on the side beam 300 of the frame. The secondary vertical hydraulic damper 200 and the anti-snake hydraulic damper 100 are arranged perpendicular to each other.

[0038] The upright plate 1 is fixedly connected to the side beam 300 of the frame by welding. Mounting holes 12 are machined into the upright plate 1, serving as the mounting interface for the anti-snake-like hydraulic damper 100. A insertion groove 11 is formed on one side edge 14 of the upright plate 1. The fixing plate 2 is inserted into the insertion groove 11 of the upright plate 1 and fixedly connected by welding. A connecting hole 21 is machined into the fixing plate 2, serving as the mounting interface for the secondary vertical hydraulic damper 200. The first snap plate 3 and the second snap plate 4 are both fixedly connected to the edge of the upright plate 1 by welding. One end of the first snap plate 3 abuts against the upper surface of the fixing plate 2 and is fixedly connected by welding; the other end of the first snap plate 3 contacts the cover plate 301 of the side beam 300 of the frame. One end of the second snap plate 4 abuts against the lower surface of the fixing plate 2 and is fixedly connected by welding; the other end of the second snap plate 4 contacts the bottom plate 302 of the side beam 300 of the frame. The fixing plate 2 can be fixed relative to the upright plate 1 under the action of the insertion slot 11, and the connection is stable. Furthermore, under the action of the first buckle plate 3 and the second buckle plate 4, the stability of the connection between the fixing plate 2 and the upright plate 1 is further improved, making it less prone to breakage and providing strong support.

[0039] This integrated damper mounting base features a compact structure and integrated design, optimizing installation space and enabling the anti-roll torsion bar 400 to pass through the frame crossbeam, thus improving the installation reliability of the anti-roll torsion bar 400. Furthermore, while installing the anti-snaking hydraulic damper 100, it can also install and fix the secondary vertical hydraulic damper 200, providing strong support for its installation.

[0040] Furthermore, referring to Figures 1 to 3 The first buckle plate 3 includes a support part 31, a connecting part 32 and a fixing part 33. The two ends of the connecting part 32 are respectively connected to the support part 31 and the fixing part 33, and the connecting part 32 is set at an angle to the support part 31 and the fixing part 33. The support part 31 abuts against the fixing plate 2.

[0041] The upper half of the upright plate 1 has a vertical edge 13, a side edge 14, and a horizontal edge 15. The support part 31 is fixedly connected to the vertical edge 13, the connecting part 32 is fixedly connected to the side edge 14, and the fixing part 33 is fixedly connected to the horizontal edge 15. The aforementioned fixed connections are all welded together by a combination of bevel welding and fillet welding. The connecting part 32 and the support part 31 are set at an obtuse angle, and the connecting part 32 and the fixing part 33 are also set at an obtuse angle, corresponding one-to-one with the angles between the vertical edge 13, the side edge 14, and the horizontal edge 15. That is, the first fastening plate 3 is perfectly fixedly connected to the edge of the upright plate 1 and can support the fixing plate 2, thereby ensuring the installation support of the secondary vertical hydraulic vibration damper 200. It should be noted that the structure of the second buckle plate 4 is the same as that of the first buckle plate 3. The edge structure of the lower half of the vertical plate 1 is the same as that of the upper half. The connection structure will not be described in detail. The second buckle plate 4 can support the fixed plate 2, thereby further ensuring stronger support for the installation of the secondary vertical hydraulic shock absorber 200.

[0042] Furthermore, referring to Figures 1 to 3 The support part 31 is provided with an abutment part 34. The longitudinal section of the abutment part 34 is an inverted triangular structure, and the abutment part 34 abuts against the fixed plate 2.

[0043] The support portion 31 has a protruding abutment portion 34. The longitudinal section of the abutment portion 34 has an inverted triangular structure, meaning that the cross-sectional area of ​​the abutment portion 34 gradually decreases from the support portion 31 to the fixed plate 2. The abutment portion 34 can provide strong support for the fixed plate 2, enabling the fixed plate 2 to have better connection structural strength relative to the upright plate 1, thereby providing strong support for the installation of the secondary vertical hydraulic vibration damper 200. Preferably, the fixed portion 33 has a protruding abutment portion 34. The longitudinal section of the abutment portion 34 has an inverted triangular structure. The fixed portion 33 contacts the frame side beam 300 through the abutment portion 34 and is fixedly connected by welding.

[0044] Furthermore, referring to Figures 1 to 3The fixing plate 2 is welded to the upright plate 1 via the insertion slot 11, and the support component is welded to the edge of the upright plate 1, and also welded to the fixing plate 2. Both the fixing plate 2 and the support component are connected to the upright plate 1 by a combination of bevel welding and fillet welding, resulting in a firm connection, high structural strength, and long service life.

[0045] Furthermore, referring to Figures 1 to 3 There are two connecting holes 21 and two mounting holes 12. The two mounting holes 12 are spaced apart along the vertical height direction of the upright plate 1, and the two connecting holes 21 are spaced apart along the horizontal direction perpendicular to the upright plate 1. The upright plate 1 also has a clearance hole 16, which is located between the two mounting holes 12. The clearance hole 16 is used to avoid the lifting ring of the anti-snake hydraulic vibration damper 100.

[0046] Mounting hole 12 serves as the mounting interface for the anti-snake hydraulic damper 100, and connecting hole 21 serves as the mounting interface for the secondary vertical hydraulic damper 200. The two spaced mounting holes 12 are vertically distributed, and the two spaced connecting holes 21 are horizontally distributed, so that the anti-snake hydraulic damper 100 and the secondary vertical hydraulic damper 200 are perpendicular to each other. The integrated design is compact and optimizes the installation space of the frame side beam 300.

[0047] This embodiment also provides a train bogie, including a frame side beam 300 and an integrated damper mounting base as described above. The frame side beam 300 includes a cover plate 301, a base plate 302, and a side upright plate 303. The two ends of the side upright plate 303 are respectively connected to the cover plate 301 and the base plate 302. The integrated damper mounting base is fixedly disposed in the U-shaped groove formed by the cover plate 301, the side upright plate 303, and the base plate 302. The upper and lower edges of the upright plate 1 are welded to the cover plate 301 and the base plate 302, respectively, and one side edge 14 of the upright plate 1 is welded to the side upright plate 303. This integrated damper mounting base can simultaneously install an anti-snaking hydraulic damper 100 and a secondary vertical hydraulic damper 200. It has a compact structure, integrated design, and optimized installation space, thereby enabling the anti-roll torsion bar 400 to pass through the frame crossbeam and improving the installation reliability of the anti-roll torsion bar 400.

[0048] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
