Description

[0002] The straddle-type monorail is a strip-shaped beam on which the train straddles and travels. It has the advantages of low noise, small turning radius, strong climbing ability, low construction cost, and extremely flexible lines. It can adapt well to the natural conditions of mountain cities and other cities, providing convenience for people's lives.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0050] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. The terms used in the following embodiments are only for the purpose of describing specific embodiments and are not intended to be used as limitations on the present application.

[0051] References to "one embodiment" or "some embodiments" etc. described in this specification mean that a particular feature, structure or characteristic described in conjunction with the embodiment is included in one or more embodiments of the present application. Thus, the phrases "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear at different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways.

[0052] The multiple involved in the embodiments of the present application means greater than or equal to two. It should be noted that in the description of the embodiments of the present application, the words "first", "second", etc. are only used for the purpose of distinguishing the description, and cannot be understood as indicating or implying relative importance, nor can they be understood as indicating or implying an order.

[0053] The "parallel" and "perpendicular" involved in this application are "substantially parallel" and "substantially perpendicular" in actual operation. "Substantially parallel" can be understood as parallel with a certain error, and similarly, "substantially perpendicular" can be understood as perpendicular with a certain error.

[0054] like Figure 1-Figure 16As shown, the straddle-type monorail train bogie provided in the embodiment of the present application includes: a frame assembly 100, a driver 300, a transmission system 400, a first fixing component 500 and a second fixing component 600. Among them, the running wheel assembly 200 includes a running wheel 210, an axle 220 and a hub 230. The running wheel 210 is detachably fixedly connected to the axle through the hub 230. The transmission system 400 includes a gear box 410 and a chain coupling 420. The driver 300 is transmission-connected to the gear box 410. The gear box 410 is detachably transmission-connected to the first end of the axle through the chain coupling 420. In this way, the driver 300 can drive the axle 220 to rotate through the gear box 410 and the chain coupling 420, and drive the running wheel 210 to rotate, thereby driving the vehicle body to run. At the same time, the axle 220 can be separated from the transmission system 400 by disassembling the chain coupling 420, so that the subsequent axle 220 drives the running wheel 210 to separate 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, only the connection between the first end of the axle 220 and the transmission system 400 needs to be removed, which reduces the number of operating steps in the process of separating the axle 220 from the frame assembly 100, saves time in replacing the running wheel 210, and improves the wheel changing efficiency.

[0056] like Figure 1-Figure 4As shown, the frame assembly 100 includes a connecting beam 111, a first fixing assembly 500 and the connecting beam 111 detachably clamp a first end of the wheel axle 220, a second fixing assembly 600 and the connecting beam 111 detachably clamp a second end of the wheel axle 220, the wheel axle 220 and the connecting beam 111 are relatively fixed in the axial direction, and the wheel axle 220 can rotate around its axis, so that the driver 300 can drive the wheel axle 220 to rotate, so that the wheel axle 220 drives the running wheel 210 to rotate; the first fixing assembly 500, the second fixing assembly 600 and the wheel axle 220 are all located at the lower side of the connecting beam 111, and the frame assembly 100 has a clearance space for the running wheel assembly 200 to detach from the frame assembly 100 from the lower side of the connecting beam 111, which Similarly, when the running wheel 210 needs to be replaced, the chain coupling 420, the first fixing component 500 and the second fixing component 600 are removed, so that the wheel axle 220 can carry the entire running wheel assembly 200 from the lower side of the connecting beam 111 in the vertical direction. Therefore, the running wheel assembly 200 can be removed without disassembling the frame assembly 100. After the running wheel assembly 200 is separated from the frame assembly 100, the running wheel 210 on the running wheel assembly 200 is removed. Within the limited axial space size, the running wheel 210 does not need to move axially, and can be directly removed in the vertical direction. This realizes the disassembly of the running wheel 210 without disassembling and changing the wheel, which saves the time of wheel changing and improves the efficiency of wheel changing.

[0057] like Figure 4 and Fig.13 As shown, a hub flange 240 is provided on the wheel axle 220, and the hub flange 240 has a taper of 1:30 to realize the positioning of the running wheel 210 on the wheel axle 220. The running wheel 210 is detachably fixedly connected to the hub flange 240 via the wheel hub 230. In this way, after disassembling the running wheel assembly 200, the running wheel 210 can be separated from the wheel axle 220 by disassembling the wheel hub 230 and the hub flange 240, so that the running wheel 210 can be disassembled to implement wheel replacement.

[0058] like Figure 1 As shown, the frame assembly 100 also includes an auxiliary running wheel group and an air spring 130, wherein the auxiliary running wheel group includes a guide wheel 121, which is installed at the four corners of the frame assembly 100 for guiding when turning; auxiliary wheels 123 are installed on the two front and rear end beams 112 of the frame assembly 100 parallel to the axis of the wheel axle 220, which are used to assist the running of the running wheel 210 and continue to support the vehicle body when the running wheel 210 has a tire blowout, etc., to provide auxiliary protection; stabilizing wheels 122 are installed at the bottom ends of the vertical beams on both sides of the frame assembly 100, which are used to prevent the monorail train from tilting and rolling over during operation, so as to ensure safe driving; an air spring 130 is installed at the top end of the middle vertical beam of the frame assembly 100, which can provide buffering support for the vehicle body.

[0059] like Figure 2 As shown, the frame in the frame assembly 100 is a gooseneck frame, which meets the strength requirements of the frame assembly 100, and the connecting beam 111 is an arched structure with low ends and high middle, which is convenient for accommodating 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, reinforcing ribs are provided on the end beam 112 parallel to the axial direction of the wheel axle 220, and the reinforcing ribs are distributed along the length direction of the end beam 112, further ensuring 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 axle 220 is clamped between the first fixing component 500 and the connecting beam 111, and the second end of the axle 220 is clamped between the second fixing component 600 and the connecting beam 111, thereby improving the stability of the first fixing component 500, the second fixing component 600 and the connecting beam 111 in clamping the running wheel assembly 200, and ensuring the safety and stability of the vehicle body operation process.

[0061] In the straddle-type monorail train bogie provided in the embodiment of the present application, the wheel axle 220 is separated from the transmission system 400 by disassembling the chain coupling 420, so there is no need to move the position of the driver 300 and the gear box 410. Since the driver 300 and the gear box 410 have a certain weight, such as Figure 2 As shown, the frame assembly 100 is also provided with a placement table 113 for placing the driver 300 and the gear box 410 to reduce the radial load of the gear box output shaft 411 and ensure the transmission stability of the transmission system 400.

[0062] like Figure 7-Figure 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, and the first chain 423 and the second chain 424 can be detachably surrounded by a ring through a chain connector 426, and after the chain connector 426 is removed, the first chain 423 and the second chain 424 can be disassembled into a bar shape, the first sprocket 421 is drivingly connected to the output shaft 411 of the gear box, the first chain 423 is meshed with the first sprocket 421, the second sprocket 422 is drivingly connected to the first end of the wheel shaft 220, and the second chain 424 is meshed with the second sprocket 422. In this way, when the driver 300 is driven, the gear box 410 drives the first sprocket 421 to rotate through the output shaft 411, and drives the second sprocket 422 to rotate through the first chain 423 and the second chain 424, so as to drive the wheel shaft 220 to rotate; when the wheel shaft 220 needs to be disassembled, the first chain 423 and the second chain 424 are disassembled into bars and synchronously separated from the first sprocket 421 and the second sprocket 422 by removing the chain connector 426, so that the second sprocket 422 and the wheel shaft 220 are separated from other transmission components, which is convenient for the subsequent disassembly of the wheel shaft 220, so as to facilitate 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 gear box output shaft 411 and the wheel shaft 220, and increasing the accuracy and stability of the power transmission.

[0063] like Fig. 9 As shown, the first chain 423 and the second chain 424 are detachably fixedly connected by a plurality of 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 penetrate and connect the first chain 423 and the second chain 424 to ensure transmission stability; any two adjacent pins 425 are detachably clamped by the chain connector 426 to make the first chain 423 and the second chain 424 form a detachable ring, which facilitates the disassembly of the chain connector 426, saves disassembly time, and improves the overall wheel changing efficiency.

[0064] In some embodiments, Fig.10 As shown, the chain connector 426 is a buckle, which forms a ring with the first chain 423 and the second chain 424 by snapping two adjacent pins 425. The buckle has a simple structure and is easy to install and disassemble, further improving 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 pin shafts 425 are connected and positioned by the fixed chain plate and fixed by the fixing bolt, thereby ensuring the connection strength and improving the transmission stability of the first chain 423 and the second chain 424.

[0066] like Fig.11 As shown, the first sprocket 421 is connected to the gearbox output shaft 411 through a spline transmission, 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, a wedge key, etc., which is not limited in the embodiment of the present application.

[0067] like Fig.12 and Fig.13 As shown, the first end of the axle 220 is provided with a keyway 221, and the second sprocket 422 is connected to the first end of the axle 220 via a flat key transmission. The keyway 221 can reduce the process difficulty and save processing steps. Of course, in other embodiments, the second sprocket 422 and the axle 220 can also be connected by a spline, a wedge key, etc., which is not limited in the present embodiment.

[0068] like Figure 8-Figure 12 As shown, in the chain coupling 420 provided in the embodiment of the present application, 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 gear box 410 and the axle 220 while ensuring the stability of the transmission.

[0069] Since the wheel axle 220 has a certain length, in order to support the wheel axle 220 and ensure the stability of transmission, as shown in FIG. Figure 7 and Fig.12 As shown, the second sprocket 422 includes a second sprocket body 4221 and a second sprocket sleeve 4222 that are fixedly connected. The second sprocket sleeve 4222 is outermostly disposed on the first end of the wheel axle 220 and is connected to the first end of the wheel axle 220 via a flat key, so that during the transmission process, the second sprocket sleeve 4222 can support the wheel axle 220; at the same time, the second sprocket sleeve 4222 increases the connection length with the wheel axle 220, thereby improving the stability of the transmission between the second sprocket 422 and the wheel axle 220 and further ensuring the stability of the vehicle driving.

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

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

[0072] like Figure 3 , Figure 6 , Figure 7 , Fig.14 , Fig.15 As shown, the first fixing assembly 500 includes: a first fixing member 510, the first fixing member 510 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, and achieve rust prevention, reduce friction and wear, improve transmission efficiency and extend service life during the transmission of the chain coupling 420; the first fixing member body 511 is detachably fixedly connected to the connecting beam 111 through 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 shaft sleeve 4222. In this way, after disassembling the first chain 423 and the second chain 424, the first fixing member 510 can be disassembled by disassembling the first bolt 512 to release the first end of the wheel shaft 220.

[0073] In actual situations, the second sprocket sleeve 4222 is provided with a first bearing (not shown in the figure), and the second sprocket sleeve 4222 is rotatably matched with the first fixing member body 511 and the connecting beam 111 through the first bearing, so that the wheel shaft 220 can rotate stably.

[0074] In order to provide a first bearing accommodation space, such as Fig.14 As shown, the first fixing member body 511 is provided with a first groove 514 for accommodating the first bearing, and the first bearing is located between the first groove 514 and the connecting beam 111. Thus, the first bearing is positioned and clamped by the first groove 514, further increasing the stability of the clamping.

[0075] like Figure 6 , Figure 7 and Fig.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 component 510, the inner surface of the oil base 520 is fitted with the outer surface of the first fixing component 510, and the oil base 520 is fitted with the connecting seat 1110 to achieve sealing of the chain coupling 420, and the oil base 520 and the connecting beam 111 are detachably fixedly connected, and an oil outlet hole 521 is provided at the bottom of the oil base 520. When the chain coupling 420 needs to be disassembled, the oil outlet hole 521 is first opened to discharge the lubricating oil, so as to facilitate the subsequent disassembly of the oil base 520 and the first fixing component 510.

[0076] Since the oil base 520 and the oil pan 513 contain lubricating oil for the first chain 423 and the second chain 424 to soak, in order to ensure the sealing of the lubricating oil, Figure 2 As shown, the side of the connecting seat 1110 close to the first chain 423 is in the shape of a circular ring, which can seal the first chain 423 and the second chain 424 between the connecting seat 1110 and the first fixed component 500, prevent the leakage of lubricating oil and the intrusion of foreign matter, ensure the stability of the transmission of the chain coupling 420, and extend the service life of the chain coupling 420; the other side of the connecting seat 1110 away from the first chain 423 is in the shape of a semicircular ring, which can be fitted with the oil base 520 to form a circular ring, thereby sealing the chain coupling 420, and the lower end of the connecting seat 1110 has a space for the wheel axle 220 to detach from the connecting beam 111, so as to ensure that the wheel axle 220 can drive the running wheel assembly 200 to detach from the frame assembly 100 in the vertical direction.

[0077] like Figure 3-Figure 5 As shown, the second end of the axle 220 is clamped between the second fixing assembly 600 and the connecting beam 111. The second fixing assembly 600 includes a second fixing member 610. The second fixing member 610 is detachably fixed to the connecting beam 111 via 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 Figure 4-Figure 5 As shown, a second bearing 810 is disposed at the second end of the axle 220 , and the axle 220 is rotatably matched 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 space for accommodating the second bearing 810, as shown in FIG. Fig.16 As shown, the second fixing member 610 is provided with a second groove 630 for accommodating the second bearing 810, and 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, further increasing 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, which can withstand the combined radial and axial loads and improve 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., which are not limited in the embodiments of the present application.

[0081] Since the connecting beam 111 has a certain thickness, such as Figure 3-Figure 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 member 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 to achieve a stable connection between the first fixing assembly 500 and the second fixing assembly 600 and the connecting beam 111.

[0082] The straddle-type monorail train bogie provided in the embodiment of the present application further includes a brake 700, for example, Figure 1 As shown, the brake 700 is a disc brake with good braking effect and reduced axial size to make the entire bogie more compact and facilitate train travel.

[0083] When the running wheel 210 of the straddle-type monorail bogie provided in the embodiment of the present application needs to be replaced and overhauled, the monorail train is first parked at the overhaul station, the frame assembly 100 and the car body are supported, the oil outlet hole 521 of the oil base 520 is first opened to discharge the lubricating oil, the oil base 520 is disassembled, and then the chain connecting member 426 is disassembled to disengage the first chain 423 and the second chain 424 from the first sprocket 421 and the second sprocket 422, so that the wheel axle 220 and the second sprocket 422 are disengaged from the transmission system 400, and then the first chain 423 and the second chain 424 are disassembled. The bolt 512 disengages the first fixing member 510 from the connecting beam 111 and releases the first end of the axle 220. Then, the second bolt 620 is removed to disengage the second fixing member 610 from the connecting beam 111 and release the second end of the axle 220. In this way, the axle 220 can drive the running wheel assembly 200 to disengage from the connecting beam 111. Then, the wheel hub 230 and the wheel hub flange 240 are removed to disengage the running wheel 210 from the wheel axle 220, so as to realize disassembly of the running wheel 210 and implement wheel changing without disassembling, thereby saving the time of wheel changing and improving the efficiency of wheel changing.

[0084] An embodiment of the present application further provides a straddle-type monorail train, which comprises the straddle-type monorail bogie in the above embodiment.

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