Description

Technical Field

[0001] This application relates to the field of straddle-type monorail train technology, and more specifically, to a straddle-type monorail train bogie and a straddle-type monorail train. Background Technology

[0002] A straddle-type monorail is a strip-shaped beam on which a train straddles and runs. It boasts advantages such as low noise, small turning radius, strong climbing ability, low construction cost, and extremely flexible operation, making it well-suited to the natural conditions of mountainous cities and providing convenience for residents. However, because monorails are mostly built in mountainous areas with complex operating conditions, the actual service life of the monorail train's running wheels is far shorter than the designed lifespan, increasing the frequency of running wheel replacement.

[0003] Currently, the wheel replacement process for monorail trains is complex. It requires unloading equipment such as bogies, cables, and pipelines from the train and arranging them in a specific order. After replacing the running wheels, the bogies, cables, and pipelines must be reconnected and installed, and the connections must be checked for correctness and security. The separation and reassembly of the bogies from the train is time-consuming. This detached wheel replacement method makes running wheel replacement complex and time-consuming, thus increasing operating costs.

[0004] In summary, how to simplify the replacement of running wheels to save replacement time and improve replacement efficiency is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0049] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0050] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. The terminology used in the following embodiments is for the purpose of describing specific embodiments only and is not intended to be a limitation of this application. As used in the specification and appended claims of this application, the singular expressions "a," "an," "the," "the," "the," and "this" are intended to also include expressions such as "one or more," unless the context clearly indicates otherwise. It should also be understood that in the embodiments of this application, "one or more" refers to one, two, or more; "and / or" describes the relationship between related objects, indicating that three relationships may exist; for example, A and / or B can represent: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship.

[0051] References to "one embodiment" or "some embodiments" as described in this specification mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0052] The "multiple" mentioned in the embodiments of this application refers to two or more. It should be noted that in the description of the embodiments of this application, terms such as "first" and "second" are used only for the purpose of distinguishing descriptions and should not be construed as indicating or implying relative importance, nor should they be construed as indicating or implying order.

[0053] The terms "parallel" and "perpendicular" used in this application refer to "basically parallel" and "basically perpendicular" in practical operation. "Basically parallel" can be understood as parallelism with a certain degree of error, and similarly, "basically perpendicular" can be understood as perpendicularity with a certain degree of error.

[0054] like Figures 1-16As shown in the embodiment of this application, the straddle-type monorail train bogie includes: a frame assembly 100, a driver 300, a transmission system 400, a first fixing component 500, and a second fixing component 600. The running wheel assembly 200 includes running wheels 210, axles 220, and hubs 230. Running wheels 210 are detachably fixed to axles via hubs 230. The transmission system 400 includes a gearbox 410 and a chain coupling 420. The driver 300 is connected to the gearbox 410. The gearbox 410 is detachably connected to the first end of the axle via the chain coupling 420. Thus, the driver 300 can drive the axle 220 to rotate via the gearbox 410 and the chain coupling 420, thereby driving the running wheels 210 to rotate and thus moving the vehicle body. At the same time, by disassembling the chain coupling 420, the axle 220 can be separated from the transmission system 400, making it easier for the axle 220 to drive the running wheels 210 to detach from the frame assembly 100.

[0055] It should be noted that the end of the axle 220 connected to the chain coupling 420 is the first end of the axle 220, and the other end of the axle 220 away from the chain coupling 420 is the second end of the axle 220. Figure 1 As shown, the second end of the axle 220 is not connected to other transmission components. In this way, it is only necessary to disconnect the connection between the first end of the axle 220 and the transmission system 400, which reduces the operation steps in the process of the axle 220 being separated from the frame assembly 100, saves the time of replacing the running wheel 210, and improves the wheel replacement efficiency.

[0056] like Figures 1-4As shown, the frame assembly 100 includes a connecting beam 111. A first fixing component 500 detachably clamps the first end of the axle 220 to the connecting beam 111, and a second fixing component 600 detachably clamps the second end of the axle 220 to the connecting beam 111. The axle 220 and the connecting beam 111 are axially fixed relative to each other, and the axle 220 is rotatable about its axis so that the driver 300 can drive the axle 220 to rotate, thereby enabling the axle 220 to drive the running wheel 210 to rotate. The first fixing component 500, the second fixing component 600, and the axle 220 are all located below the connecting beam 111, and the frame assembly 100 has clearance space for the running wheel assembly 200 to disengage from the underside of the connecting beam 111. Thus, when the traveling wheel 210 needs to be replaced, the chain coupling 420, the first fixing component 500, and the second fixing component 600 are disassembled. This allows the wheel axle 220, along with the entire traveling wheel assembly 200, to detach vertically from the frame assembly 100 from the underside of the connecting beam 111. Therefore, the traveling wheel assembly 200 can be disassembled without disassembling the frame assembly 100. After the traveling wheel assembly 200 is detached from the frame assembly 100, the traveling wheel 210 on the traveling wheel assembly 200 can be disassembled. Within the limited axial space, the traveling wheel 210 does not need to move axially and can be directly removed vertically. This achieves the disassembly and replacement of the traveling wheel 210 without disassembly, saving replacement time and improving replacement efficiency.

[0057] like Figure 4 and Figure 13 As shown, a hub flange 240 is provided on the axle 220. The hub flange 240 has a taper of 1:30 to position the running wheel 210 on the axle 220. The running wheel 210 is detachably fixed to the hub flange 240 via the hub 230. Thus, after disassembling the running wheel assembly 200, the running wheel 210 can be disengaged from the axle 220 by removing the hub 230 and the hub flange 240, so that the running wheel 210 can be removed to replace the wheel.

[0058] like Figure 1 As shown, the frame assembly 100 also includes auxiliary running wheel sets and air springs 130. The auxiliary running wheel sets include guide wheels 121, which are installed at the four corners of the frame assembly 100 for guiding during turns. Auxiliary wheels 123 are installed on the two end beams 112 of the frame assembly 100, which are parallel to the axial direction of the wheel axle 220, to assist the running wheels 210 in driving and to continue to support the car body in the event of a tire blowout, providing auxiliary protection. Stabilizing wheels 122 are installed at the bottom of the vertical beams on both sides of the frame assembly 100 to prevent the monorail train from tilting or overturning during operation, ensuring safe operation. An air spring 130 is installed at the top of the middle vertical beam of the frame assembly 100 to provide cushioning support for the car body.

[0059] like Figure 2 As shown, the frame of the frame assembly 100 is a gooseneck frame, which meets the strength requirements of the frame assembly 100. The connecting beam 111 is an arched structure that is low at both ends and high in the middle, which facilitates the accommodation of the wheel axle 220 under the connecting beam 111, while ensuring the strength of the frame assembly 100. In order to further improve the strength of the frame assembly 100, the end beam 112, which is parallel to the axial direction of the wheel axle 220, is provided with reinforcing ribs, and the reinforcing ribs are distributed along the length direction of the end beam 112, which further ensures the strength of the frame assembly 100.

[0060] The connecting beams 111 are distributed on both sides of the running wheel 210 so that the first end of the wheel axle 220 is clamped between the first fixing component 500 and the connecting beams 111, and the second end of the wheel axle 220 is clamped between the second fixing component 600 and the connecting beams 111. This improves the stability of the first fixing component 500, the second fixing component 600 and the connecting beams 111 clamping the running wheel assembly 200, and ensures the safe and stable operation of the vehicle body.

[0061] In the straddle-type monorail train bogie provided in this application embodiment, the axle 220 is separated from the transmission system 400 by disassembling the chain coupling 420. Therefore, it is not necessary to move the positions of the drive unit 300 and the gearbox 410. Since the drive unit 300 and the gearbox 410 have a certain weight, such as Figure 2 As shown, the frame assembly 100 is also provided with a placement platform 113 for placing the driver 300 and the gearbox 410 to reduce the radial load on the gearbox output shaft 411 and ensure the stability of the transmission system 400.

[0062] like Figures 7-12As shown, the chain coupling 420 includes a first sprocket 421, a second sprocket 422, a first chain 423, and a second chain 424. The first chain 423 and the second chain 424 are detachably fixedly connected. The first chain 423 and the second chain 424 can be detachably arranged in a ring via a chain connector 426. After disassembling the chain connector 426, the first chain 423 and the second chain 424 can be disassembled into strips. The first sprocket 421 is driven by the output shaft 411 of the gearbox, and the first chain 423 meshes with the first sprocket 421. The second sprocket 422 is driven by the first end of the axle 220, and the second chain 424 meshes with the second sprocket 422. Thus, when driven by the driver 300, the gearbox 410 drives the first sprocket 421 to rotate via the output shaft 411, and drives the second sprocket 422 to rotate via the first chain 423 and the second chain 424, thereby driving the axle 220 to rotate. When it is necessary to disassemble the axle 220, the chain connector 426 is disassembled, so that the first chain 423 and the second chain 424 are disassembled into strips and simultaneously separated from the first sprocket 421 and the second sprocket 422, so that the second sprocket 422 and the axle 220 are separated from other transmission components, which facilitates the subsequent disassembly of the axle 220 and the subsequent disassembly of the running wheel assembly 200. At the same time, since the first chain 423 and the second chain 424 are detachably fixedly connected as concentric circles, the coaxiality error between the axes of the first sprocket 421 and the second sprocket 422 is reduced, thereby reducing the coaxiality error of the transmission between the gearbox output shaft 411 and the axle 220, and increasing the accuracy and stability of the power transmission.

[0063] like Figure 9 As shown, the first chain 423 and the second chain 424 are detachably fixedly connected by multiple pins 425. In order to ensure stable transmission between the first chain 423 and the second chain 424, the pins 425 are long pins that pass through and connect the first chain 423 and the second chain 424 to ensure transmission stability. Any two adjacent pins 425 are detachably snapped together by chain connectors 426 so that the first chain 423 and the second chain 424 form a detachable ring. At the same time, it is convenient to disassemble the chain connectors 426, save disassembly time, and improve the overall wheel changing efficiency.

[0064] In some embodiments, such as Figure 10 As shown, the chain connector 426 is a snap fastener. It connects the first chain 423 and the second chain 424 into a ring by snapping together two adjacent pins 425. The snap fastener structure is simple and easy to install and disassemble, which further improves the efficiency of disassembling the chain coupling 420.

[0065] In some other embodiments, the chain connector 426 includes a fixed chain plate and a fixing bolt. Two adjacent pins 425 are connected and positioned by the fixed chain plate and fixed by the fixing bolt, which ensures the connection strength and improves the stability of the transmission of the first chain 423 and the second chain 424.

[0066] like Figure 11 As shown, the first sprocket 421 and the gearbox output shaft 411 are connected by a spline drive, which ensures the strength of the connection and improves the stability of the transmission. Of course, in other embodiments, the first sprocket 421 and the gearbox output shaft 411 can also be connected by a flat key, wedge key, or other means, and this application does not limit this.

[0067] like Figure 12 and Figure 13 As shown, a keyway 221 is provided at the first end of the axle 220. The second sprocket 422 is connected to the first end of the axle 220 via a flat key. Providing a keyway 221 can reduce the difficulty of the manufacturing process and save machining steps. Of course, in other embodiments, the second sprocket 422 and the axle 220 can also be connected by splines, wedge keys, etc. This application embodiment does not limit this.

[0068] like Figures 8-12 As shown, in the chain coupling 420 provided in this embodiment, the first sprocket 421, the second sprocket 422, the first chain 423, and the second chain 424 all have 20 teeth, which can better adapt to the transmission space between the gearbox 410 and the axle 220, while ensuring the stability of the transmission.

[0069] Since the axle 220 has a certain length, in order to support the axle 220 and ensure the smoothness of transmission, such as Figure 7 and Figure 12 As shown, the second sprocket 422 includes a second sprocket body 4221 and a second sprocket bushing 4222 that are fixedly connected. The second sprocket bushing 4222 is sleeved on the first end of the axle 220 and connected to the first end of the axle 220 by a flat key. In this way, during transmission, the second sprocket bushing 4222 can support the axle 220. At the same time, the second sprocket bushing 4222 increases the connection length with the axle 220, improves the stability of the transmission between the second sprocket 422 and the axle 220, and further ensures the smoothness of the vehicle's movement.

[0070] like Figure 4 and Figure 7 As shown, the first fixing component 500 and the connecting beam 111 detachably clamp the second sprocket bushing 4222, which increases the clamping area of ​​the first fixing component 500 and increases the stability of the first fixing component 500 clamping the wheel axle 220.

[0071] like Figure 2As shown, the bottom side of the connecting seat 111 is provided with a connecting seat 1110 corresponding to the chain coupling 420, so as to achieve sealing protection for the chain coupling 420.

[0072] like Figure 3 , Figure 6 , Figure 7 , Figure 14 , Figure 15 As shown, the first fixing component 500 includes a first fixing member 510, which includes a first fixing member body 511 and an oil pan 513 fixedly connected. The oil pan 513 is located at the lower end of the first chain 423 and the second chain 424, so that the first chain 423 and the second chain 424 can contact the lubricating oil in the oil pan 513, thereby achieving rust prevention, reducing friction and wear, improving transmission efficiency, and extending service life during the transmission of the chain coupling 420. The first fixing member body 511 is detachably fixed to the connecting beam 111 by a first bolt 512, and the first bolt 512 can pass through the connecting seat 1110, so that the first fixing member body 511 and the connecting seat 1110 can detachably clamp the second sprocket bushing 4222. Thus, after disassembling the first chain 423 and the second chain 424, the first fixing member 510 can be disassembled by removing the first bolt 512 to release the first end of the wheel axle 220.

[0073] In practice, the second sprocket bushing 4222 is equipped with a first bearing (not shown in the figure). The second sprocket bushing 4222 rotates with the first fixing body 511 and the connecting beam 111 through the first bearing, so that the axle 220 can rotate stably.

[0074] In order to provide space for the first bearing, such as Figure 14 As shown, the first fixing body 511 has a first groove 514 for accommodating the first bearing. The first bearing is located between the first groove 514 and the connecting beam 111. In this way, the first bearing is positioned and clamped by the first groove 514, which further increases the stability of clamping.

[0075] like Figure 6 , Figure 7 and Figure 15 As shown, the first fixing component 500 also includes an oil base 520, which is located on the bottom side of the first fixing member 510. The inner surface of the oil base 520 is in contact with the outer surface of the first fixing member 510, and the oil base 520 is in contact with the connecting seat 1110 to achieve a seal on the chain coupling 420. The oil base 520 and the connecting beam 111 are detachably fixedly connected. The bottom of the oil base 520 is provided with an oil outlet hole 521. When it is necessary to disassemble the chain coupling 420, the oil outlet hole 521 is opened first to allow the lubricating oil to be discharged, which facilitates the subsequent disassembly of the oil base 520 and the first fixing member 510.

[0076] Since both the oil base 520 and the oil pan 513 contain lubricating oil for the first chain 423 and the second chain 424 to be immersed in, in order to ensure the lubricating oil is sealed, such as Figure 2 As shown, the side of the connecting seat 1110 closest to the first chain 423 is annular, which can seal the first chain 423 and the second chain 424 between the connecting seat 1110 and the first fixing component 500, preventing lubricating oil leakage and foreign matter intrusion, ensuring the stability of the chain coupling 420 transmission, and extending the service life of the chain coupling 420; the other side of the connecting seat 1110 away from the first chain 423 is semi-annular, which can fit with the oil base 520 to form an annular shape, thereby sealing the chain coupling 420. The lower end of the connecting seat 1110 has space for the wheel axle 220 to disengage from the connecting beam 111, so as to ensure that the wheel axle 220 can drive the traveling wheel assembly 200 to disengage from the frame assembly 100 in the vertical direction.

[0077] like Figures 3-5 As shown, the second end of the axle 220 is clamped between the second fixing component 600 and the connecting beam 111. The second fixing component 600 includes a second fixing member 610, which is detachably fixed to the connecting beam 111 by a second bolt 620. Thus, the second fixing member 610 can be disassembled by removing the second bolt 620 to release the second end of the axle 220.

[0078] like Figures 4-5 As shown, a second bearing 810 is provided at the second end of the axle 220. The axle 220 rotates with the second fixing member 610 and the connecting beam 111 through the second bearing 810, so that the axle 220 can rotate stably.

[0079] In order to provide a housing space for the second bearing 810, such as Figure 16 As shown, the second fixing member 610 has a second groove 630 for accommodating the second bearing 810. The second bearing 810 is located between the second groove 630 and the connecting beam 111. In this way, the second bearing 810 is positioned and clamped by the second groove 630, which further increases the stability of clamping the wheel axle 220.

[0080] In some embodiments, the first bearing and the second bearing 810 are double-row tapered roller bearings, capable of withstanding combined radial and axial loads, thereby improving the support stability of the axle 220. Of course, the first bearing and the second bearing 810 can also be deep groove ball bearings, cylindrical roller bearings, etc., and this application embodiment does not limit this.

[0081] Because the connecting beam 111 has a certain thickness, such as Figures 3-7As shown, the first bolt 512 and the second bolt 620 are both long bolts to ensure that the first bolt 512 can pass through the first fixing body 511 and the connecting beam 111, and the second bolt 620 can pass through the second fixing member 610 and the connecting beam 111, so as to achieve a stable connection between the first fixing component 500 and the second fixing component 600 and the connecting beam 111.

[0082] The straddle-type monorail train bogie provided in this application embodiment also includes a brake 700, for example, such as Figure 1 As shown, brake 700 is a disc brake, which has a good braking effect and reduces the axial dimension, making the entire bogie more compact and facilitating train operation.

[0083] When the running wheels 210 of the straddle-type monorail bogie provided in this application need to be replaced or repaired, the monorail train is first parked at the maintenance station, and the frame assembly 100 and the car body are supported. First, the oil outlet 521 of the oil base 520 is opened to drain the lubricating oil. The oil base 520 is then disassembled. Next, the chain connector 426 is disassembled so that the first chain 423 and the second chain 424 are disengaged from the first sprocket 421 and the second sprocket 422, thereby disengaging the wheel axle 220 and the second sprocket 422 from the transmission system 400. Then, the first chain 423 is disassembled. Bolt 512 is used to disengage the first fixing member 510 from the connecting beam 111, releasing the first end of the wheel axle 220. Then, the second bolt 620 is removed to disengage the second fixing member 610 from the connecting beam 111, releasing the second end of the wheel axle 220. This allows the wheel axle 220 to drive the running wheel assembly 200 away from the connecting beam 111. Then, the wheel hub 230 and wheel hub flange 240 are removed, allowing the running wheel 210 to disengage from the wheel axle 220. This allows for wheel replacement without disassembling the running wheel 210, saving time and improving efficiency.

[0084] This application also provides a straddle-type monorail train, which includes the straddle-type monorail bogie described in the above embodiments.

[0085] Since the aforementioned straddle-type monorail bogie has the aforementioned technical effects, and the aforementioned straddle-type monorail train includes the aforementioned straddle-type monorail bogie, the aforementioned straddle-type monorail train also has the corresponding technical effects, which will not be elaborated here.
