[0004] With the continuous acceleration of urbanization, the expansion of urban scale, the rapid development of urban transportation, and population growth, space resources are constantly decreasing, making the operation of ground rail transit more difficult. As a result, the transportation operation solution of suspended monorail trains has emerged.

[0005] Compared with traditional rail transit such as subways, light rail, and trams, monorails have lower construction costs and require less land. They can be erected between cities, and the columns can be dismantled and reused, which helps alleviate traffic congestion and also provides tourists with a new sightseeing experience.

[0006] The weight of the monorail is crucial to its operational status. Currently, monorails are quite heavy. The design of traditional monorail structural forms for weight optimization has reached its limit. Therefore, a new structural form is needed to meet the lightweight design requirements of monorails.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0041] The embodiments of this application are described below with reference to Figures 1-4. This embodiment provides a frame including a top plate 100, two web plates 200, two side plates 300, and a bottom plate 400. The top plate 100 is concave from both ends towards the central axis. The two web plates 200 are respectively connected to both sides of the top plate 100 in the width direction. The upper surface of the web plates 200 is adapted to the top plate 100, and the middle portion of the lower surface of the web plates 200 extends away from the top plate 100, forming an extension section 210. The two side plates 300 are respectively connected to both sides of the top plate 100 in the length direction, and the two side plates 300 are respectively connected to the lower surfaces of the two web plates 200. The side plates 300 have a bent portion 310 at the position of the extension section 210, and the bent portion 310 is connected to the extension section 210. The bottom plate 400 is connected to the two web plates 200 and the two side plates 300.

[0042] In this embodiment, by making the top plate 100 concave from both ends toward the central axis and extending the middle of the lower surface of the web plate 200 away from the top plate 100, the web plate 200 is installed on the lower surface of the top plate 100, and the top plate 100 and the web plate 200 can form a "Y"-shaped structure. With the installation of the side plates 300 and the bottom plate 400, a "Y"-shaped frame is formed. Based on the "Y"-shaped frame, the structure of the frame can be more compact and occupy less space. The "Y"-shaped frame can meet the operational needs of the frame while greatly reducing the use of structural components such as plates and beams, thus greatly reducing the weight of the frame. In addition, the "Y"-shaped frame can also reduce the thickness of the plates, and the frame can be formed by welding thinner plates to meet the operational needs of the frame, further reducing the weight of the frame.

[0043] As shown in Figure 1, the height of both ends of the top plate 100 is higher than the height of the central axis. The two ends of the top plate 100 are raised upwards, and the middle part of the top plate 100 is recessed downwards. The middle part of the top plate 100 also has a straight section and an inclined section, thus forming an irregular top plate 100 structure.

[0044] As shown in Figure 1, the upper surface of the web 200 is connected to the top plate 100. To ensure the stability of the overall structure, the shape of the upper surface of the web 200 is the same as that of the top plate 100. The lower surface of the web 200 is connected to the side plate 300. To ensure the stability of the overall structure, the shape of the lower surface of the web 200 is the same as that of the side plate 300. The web 200 itself is also Y-shaped. The extension segment 210 in the middle of the lower surface of the web 200 extends downwards, matching the curved shape of the upper surface of the web 200, thus forming a Y-shaped web 200. When assembling to form a frame, a Y-shaped frame structure can be formed, making the frame structure compact and lighter. The extension segment 210 of the web 200 can be integrally formed or welded to the upper structure of the web 200.

[0045] The side plates 300 are located on both sides of the top plate 100 along its length and are used to close the opening areas of the top plate 100 and the web plate 200.

[0046] The top plate 100, web plate 200, side plate 300, and bottom plate 400 are connected by welding. All components, including the top plate 100, web plate 200, side plate 300, and bottom plate 400, can be made of domestically produced S355 steel plate. The plate thickness of all components can be set to 8mm, which, compared to the 12mm plate thickness of traditional monorail frames, allows for a more compact structure, reduced space requirements, and significantly reduced plate thickness. This ensures structural stability and operational safety while greatly reducing the weight of the frame.

[0047] According to the framework provided in this application, the upper surface of the top plate 100 is provided with stabilizing wheel mounting seats 110 near both ends. The stabilizing wheel mounting seat 110 includes two spaced and parallel vertical plates 1110, a reinforcing plate 1120 disposed between the two vertical plates 1110, and a horizontal plate 1130 located above the vertical plates 1110 and connected to the two vertical plates 1110 and the reinforcing plate 1120. The horizontal plate 1130 is provided with a stabilizing wheel mounting interface 1140, and the reinforcing plate 1120 is provided with a weight reduction hole 1150.

[0048] The stabilizing wheel mounting base 110 constructed on the top plate 100, together with its own stabilizing wheel mounting interface 1140, is used to connect the stabilizing wheel. The stabilizing wheel installed at this position can also act as a yaw stop. When the rail vehicle passes through a curve, under the action of centrifugal force, the car body and frame will deflect outward. At this time, the magnitude of the deflection angle can be constrained by the stabilizing wheel, which can effectively limit the torsion of the car body relative to the bogie, thereby preventing interference between components.

[0049] As shown in Figure 4, the stabilizer wheel mounting base 110 includes two vertical plates 1110, a reinforcing plate 1120, and a horizontal plate 1130. These three plates can be integrally stamped to form the stabilizer wheel mounting base 110. After forming, the stabilizer wheel mounting base 110 is welded to the upper surface of the top plate 100. The reinforcing plate 1120 provides structural reinforcement, facilitating load transfer and increasing the structural strength of the stabilizer wheel mounting base 110. Weight-reducing holes 1150 are provided on the reinforcing plate 1120 to ensure structural strength while maintaining a lower weight, thus facilitating lightweight design of the frame.

[0050] As shown in Figures 1-3, gearbox hangers 320 are respectively constructed on the two side plates 300 for mounting gearboxes. Since gearbox hangers 320 are provided on both side plates 300, the mounting nodes of the gearbox hangers are double nodes, thereby improving the radial stiffness and torsional stiffness.

[0051] In this embodiment, the gearbox hanger 320 has a grooved gearbox hanger opening 330, and the opening of the gearbox hanger opening 330 faces away from the web plate 200. After the grooved gearbox hanger opening 330 forms a double-node installation node, it can better improve the radial stiffness and torsional stiffness.

[0052] In another embodiment, the gearbox hanger 320 is formed with an annular gearbox hanger 330. After the annular gearbox hanger 330 forms a double-node mounting node, it can better improve the radial stiffness and torsional stiffness.

[0053] As shown in Figure 1, a travel safety bracket 340 is connected to the end of the gearbox hanger 320 away from the side plate 300, and a bolster mounting base 350 is connected to the end of the travel safety bracket 340 away from the gearbox hanger 320. The travel safety bracket 340 can support the upper top plate 100, gearbox hanger 320 and other structures, while also providing a smooth transition between the upper structure and the bolster mounting base 350, and making the bolster mounting base 350 easy to process and maintain.

[0054] According to the framework provided in this application, each of the two side plates 300 has a motor mounting base 360 ​​at one end near the top plate 100, and the motor mounting base 360 ​​has a motor mounting interface 370. It is understood that the motor mounting base 360 ​​can be used to connect a motor, and the corresponding motor mounting interface 370 is configured to facilitate the fixing of the motor by fasteners.

[0055] As shown in Figure 2, the two side plates 300 have inclined sections 380 formed between the bending part 310 and the motor mounting base 360, and a spring mounting base 390 is installed on each of the two inclined sections 380.

[0056] The primary spring mounting bracket is used to install the primary spring. The two primary spring mounting brackets are respectively installed on the inclined sections 380 of the two side plates 300, so that the two primary spring mounting brackets are arranged in a "V" shape. The two primary spring mounting brackets arranged in a "V" shape can prevent overshoot and play the role of preventing overshoot and stopping.

[0057] In this embodiment, the two web plates 200 are respectively provided with side current collector mounting seats 220 above the spring mounting seats, or the side current collector mounting seat 220 is provided at the center of the top plate 100. By providing two side current collector mounting seats 220 on the frame, the side current collectors can be installed in different positions according to actual usage requirements, avoiding restrictions on the installation position of the side current collectors and improving the flexibility of side current collector installation.

[0058] As shown in Figure 3, a frame cavity 500 is formed by the top plate 100, two web plates 200, two side plates 300 and bottom plate 400, and at least two stiffening plates 510 are installed at intervals in the frame cavity 500.

[0059] The internal stiffeners 510 are used to strengthen the structure of the frame. Based on the "Y"-shaped frame structure formed by the top plate 100, web plate 200, side plate 300 and bottom plate 400, the number of stiffeners 510 used inside the frame cavity 500 will be reduced. Using fewer stiffeners 510 can ensure the stability of the frame structure and meet the usage requirements, further ensuring the lightweight of the frame.

[0060] Based on the aforementioned structure, a welded steel structure frame that is simple, novel, compact, lightweight, and easy to install and disassemble can be provided for suspended monorail trains.

[0061] On the other hand, this application also provides a bogie, including the frame as described in the foregoing embodiments.

[0062] In this embodiment, by setting the aforementioned frame on the bogie, since the top plate 100 of the frame is concave from both ends toward the central axis and the middle of the lower surface of the web plate 200 extends away from the top plate 100, after the web plate 200 is installed on the lower surface of the top plate 100, the top plate 100 and the web plate 200 can form a "Y"-shaped structure. With the installation of the side plates 300 and the bottom plate 400, a "Y"-shaped frame is formed. Based on the "Y"-shaped frame form, the frame structure can be more compact and occupy less space. The "Y"-shaped frame form can meet the operational requirements of the frame while greatly reducing the use of structural components such as plates and beams, thus greatly reducing the weight of the frame. Furthermore, the "Y"-shaped frame can also reduce the thickness of the plates, allowing for the welding of thinner plates to form the frame and meet the operational requirements of the frame, further reducing the weight of the frame.

[0063] In another aspect, this application also provides a rail vehicle, particularly suitable for monorails, which includes a car body equipped with bogies as described in the foregoing embodiments.

[0064] In this embodiment, by installing the aforementioned bogie on the body of the rail vehicle, the top plate 100 of the frame is recessed from both ends toward the central axis, and the middle of the lower surface of the web plate 200 extends away from the top plate 100. After the web plate 200 is installed on the lower surface of the top plate 100, the top plate 100 and the web plate 200 can form a "Y"-shaped structure. With the installation of the side plates 300 and the bottom plate 400, a "Y"-shaped frame is formed. Based on the "Y"-shaped frame, the structure of the frame can be more compact and occupy less space. The "Y"-shaped frame can meet the operational requirements of the frame while greatly reducing the use of structural components such as plates and beams, thus greatly reducing the weight of the frame. Furthermore, the "Y"-shaped frame can reduce the thickness of the plates, allowing for the welding of thinner plates to form the frame and meet the operational requirements of the frame, further reducing the weight of the frame.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
