Description

Technical Field

[0001] This utility model belongs to the field of bogie technology, and specifically relates to a bogie system and its integrated mounting bracket. Background Technology

[0002] The bogie system of rail transit vehicles is equipped with a sand-spraying device, an obstacle remover, and a wheel flange lubrication device. These three components are fixed to the bogie via their respective mounting brackets to ensure safe train operation under complex conditions. Specifically: the sand-spraying device sprays sand particles onto the rail surface under low-adhesion conditions such as rain and snow, instantly increasing the friction coefficient between the wheel and rail, thereby ensuring sufficient traction and emergency braking capability; the obstacle remover, installed at the front of the bogie, removes small obstacles from the track to prevent them from impacting the wheelsets and bogie frame, reducing the risk of equipment damage; and the wheel flange lubrication device continuously supplies a small amount of lubricant to the contact area between the wheel flange and the rail, significantly reducing wheel flange wear and rail side wear, extending wheel and rail service life, and reducing operating noise.

[0003] However, in the existing technology, the three sets of functional components mentioned above all use independent mounting brackets, which results in a dispersed overall structure of the bogie, a large number of parts, and low space utilization. This not only increases manufacturing and maintenance costs, but also hinders the lightweight and modular design of the bogie.

[0004] Therefore, how to achieve sand spreading, obstacle removal and wheel rim lubrication functions on the same mounting frame to simplify the structure is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0033] 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.

[0034] The core of this utility model is to provide a bogie system and its integrated mounting bracket, which realizes sand spreading, obstacle removal and wheel flange lubrication functions on the same mounting bracket, so as to simplify the structure and improve maintenance efficiency.

[0035] To enable those skilled in the art to better understand the technical solutions provided by this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] Please refer to Figures 1-7 The present invention provides an integrated mounting bracket for a bogie system, including a bracket body 100. The bracket body 100 has a certain degree of bending in order to meet the installation space requirements of different components, and mainly includes an upper end, a middle section and a lower end.

[0037] Specifically, the upper end of the support body 100 is provided with anti-detachment screw holes 110 for overlapping with the side beam of the bogie system, and is fixed to the side beam of the bogie frame 500 by anti-detachment bolts. The upper end of the support body 100 extends a portion towards the upper surface of the side beam, overlaps the upper surface of the side beam, and is connected to the side beam of the bogie frame 500 by anti-detachment bolts to achieve the purpose of preventing detachment.

[0038] The middle section of the support body 100 serves as a transition, and the lower end of the support body 100 has a flange set towards the wheel side of the bogie system. The flange is offset towards the wheel side of the middle section so that the mounting position is closer to the wheel. The flange is used to connect the wheel flange lubrication device 200, the sand spreading device 300 and the obstacle remover 400 respectively.

[0039] This utility model provides an integrated mounting bracket for a bogie system. Utilizing a single bracket body 100 as a load-bearing base, it provides mounting positions for three devices: a wheel flange lubrication device 200, a sand spreading device 300, and a obstacle remover 400. It possesses sufficient structural strength and rigidity, reducing the number of bogie components. Furthermore, the bracket body 100 is installed at the end of the bogie system, optimizing the bogie layout and improving space utilization. The bracket body 100 is a one-piece molded structure, simplifying installation and maintenance processes. Its modular design supports overall or separate disassembly and assembly, reducing maintenance time by more than 30% and effectively improving maintenance efficiency.

[0040] To balance connection strength and lightweight design, the upper and middle sections of the support body 100 utilize hollow beams, with the thickness of the hollow beams gradually decreasing from top to bottom along the height direction. Thicker hollow beams have higher structural strength, while thinner ones have weaker structural strength. This is particularly true at the upper section where the support body 100 connects to the side beams and in the transitional middle section, where increased connection strength is necessary.

[0041] Furthermore, such as Figure 1As shown, the upper and middle sections of the bracket body 100 have an L-shaped structure. Its shape is first bent along the axle direction and then bent along the vehicle's forward direction, forming an overall L-shape.

[0042] In a specific embodiment, the flange at the lower end of the support body 100 is a plate-like structure. The flange and the middle section of the support body 100 are reinforced by stiffening plates 140. The use of stiffening plates 140 further strengthens the connection between the flange and the middle section of the support body 100, preventing deformation or breakage and improving the overall strength of the integrated support body 100. The number of stiffening plates 140 can be one or multiple plates spaced apart. The stiffening plates 140 are perpendicular to the flange and the middle section. Through topology optimization design, the support body 100 reduces redundant materials, especially by arranging the stiffening plates 140 in stress concentration areas, achieving a balance between strength and weight.

[0043] To make more reasonable use of space, a wheel flange lubrication mounting hole 130 is provided at the top of the flange, a sand spray nozzle mounting hole 160 and a obstacle remover mounting hole 150 are provided at the bottom. The wheel flange lubrication device 200, the sand spray device 300 and the obstacle remover 400 are installed in the above three mounting holes, so that the above three devices are installed on the side beam of the bogie frame.

[0044] The support body 100 is designed with topology optimization, and a weight reduction hole 120 is opened in the middle section of the support body 100 to reduce redundant materials.

[0045] In a specific embodiment, the support body 100 is an aluminum alloy support. It is made of high-strength, lightweight aluminum alloy as the main frame. Through material selection and structural optimization, the weight of the support body 100 is reduced by 20% compared to traditional split designs, while still meeting strength requirements.

[0046] For each wheel, an integrated mounting bracket can be used to install three devices: a wheel flange lubrication device 200, a sand spreading device 300, and a obstacle remover 400. Figure 2 and Figure 3 As shown, there are multiple integrated mounting brackets, and each integrated mounting bracket corresponds one-to-one with each wheel of the bogie system.

[0047] In addition, this utility model also provides a bogie system, including a bogie frame 500, a wheel flange lubrication device 200, a sand spreading device 300, a obstacle remover 400, and an integrated mounting bracket for the bogie system as described in the above specific embodiments.

[0048] The nozzle of the sand spreading device 300 is mounted on the support body 100 via a nozzle adjustment mechanism. The sand spreading device 300 is installed at the front end of the support body 100, and the height of the nozzle from the rail surface is adjusted using the nozzle adjustment mechanism.

[0049] The obstacle remover 400 is detachably connected to the support body 100 via an obstacle remover plate. The obstacle remover 400 is located below the nozzle of the sand spreading device 300, and an elastic buffer assembly is provided between the obstacle remover 400 and the obstacle remover plate. Specifically, the obstacle remover 400 is mounted on a detachable obstacle remover plate extending from the lower part of the support body 100 and is connected via the elastic buffer assembly to reduce vibration transmission.

[0050] The lubrication nozzle of the wheel flange lubrication device 200 is mounted on the support body 100 via a nozzle adjustment mechanism. The distance between the nozzle and the wheel is adjusted longitudinally using the nozzle adjustment mechanism, where "longitudinal" refers to the forward and backward direction of the rail vehicle. This allows for optimization of the lubrication effect according to actual needs.

[0051] like Figure 5 As shown, the nozzle adjustment mechanism includes a support plate, a support base, and a locking mechanism. One end of the support plate has a barrier removal device mounting hole 150, the middle section has a strip groove, and the other end has a support base. The support base has mounting holes for the nozzles of the sand-spreading device 300 to pass through. The locking mechanism restricts the relative movement of the nozzles on the support base. By adjusting the relative position of the strip groove on the support plate and the sand-spreading nozzle mounting hole 160 on the support body 100, the height of the nozzles and barrier removal device 400 from the rail surface can be adjusted. Finally, the support plate and the support body 100 are tightened with bolts.

[0052] By mounting the nozzles of the sand-spreading device 300 and the obstacle remover 400 on the same support plate and using an upper-lower arrangement, longitudinal space can be effectively utilized, reducing the lateral dimensions of the bogie and facilitating train passage through narrower track areas. Simultaneously, functional zoning can be optimized, ensuring no overlap between the nozzle's sand-spreading area and the obstacle remover 400's cleaning area, achieving functional separation and preventing mutual interference. Furthermore, sharing the rigidity of the support plate enhances the overall load-bearing capacity. Using the sand-spreading device 300 to pre-treat the rails reduces the risk of the obstacle remover 400 getting stuck on obstacles. The obstacle remover 400's arrangement also protects the sand-spreading device 300 from impacts by large obstacles, thereby improving the overall performance and safety of the system.

[0053] Of course, the above-mentioned nozzle adjustment mechanism and spray head adjustment mechanism can also be used in conjunction with other telescopic adjustment components to achieve height adjustment, which will not be further limited here.

[0054] Therefore, the integrated mounting bracket in this case enables sand spreading, obstacle removal, and wheel rim lubrication functions to be performed on the same mounting base, thereby simplifying the structure, reducing weight, and improving maintenance efficiency.
