[0044] In the present specification, the reference to “one embodiment” or “some embodiments” means that a particular feature, structure, or characteristic described in connection with the embodiment is included in one or more embodiments of the present application. Therefore, the statements “in one embodiment,” “in some embodiments,” “in other embodiments,” “in additional embodiments,” and the like appearing in various places throughout the specification are not necessarily all referring to the same embodiment, but are meant to signify one or more, but not all embodiments, unless otherwise specifically indicated. The terms “comprising,” “including,” “having” and their conjugates, mean “including but not limited to,” unless otherwise specifically indicated.

[0047] AsFigures 1-14 As shown, the straddle-type monorail train bogie provided by the embodiment of the application comprises a frame assembly 100, a running wheel assembly 200, a fastening assembly 500, a driver 300 and a gear box 400. The running wheel assembly 200 comprises a running wheel 210, an axle 220 and a wheel hub 230. The wheel hub 230 is fixedly connected with the axle 220. The running wheel 210 is detachably fixedly connected with the wheel hub 230 through the fastening assembly 500. Specifically, the running wheel 210 comprises a tire and a rim which are fixedly connected. The wheel hub 230 is detachably fixedly connected with the rim through the fastening assembly. In this way, the running wheel 210 can be separated from the axle 220 by detaching the fastening assembly 500. The fastening assembly 500 is provided with a clamping structure. The fastening assembly 500 can be separated from the running wheel 210 and the wheel hub 230 through a clamping piece 600 cooperating with the clamping structure. In this way, the clamping piece 600 can stably and conveniently clamp the fastening assembly 500 in a small operation space, so as to save the dismounting time of the running wheel 210 and improve the dismounting efficiency of the running wheel 210.

[0048] In actual conditions, in order to ensure the connection strength of the running wheel 210 and the wheel hub 230, the fastening assembly 500 is multiple, and the multiple fastening assemblies 500 are sequentially distributed along the axial direction of the wheel hub 230, so as to ensure the stable connection of the running wheel 210 and the wheel hub 230 and realize the stable running of the vehicle body.

[0049] As shown, Figure 1 The driver 300 is in transmission connection with the axle 220 through the gear box 400, so as to drive the running wheel 210 to rotate and realize the running of the vehicle body. It should be noted that the gear box 400 is in transmission connection with the first end of the axle 220. The running wheel 210 is separated from the axle 220 along the second end of the axle 220, so that the process of dismounting the running wheel 210 does not need to disassemble the axle 220, and the dismounting efficiency of the running wheel 210 is further improved.

[0050] The frame assembly 100 comprises a frame body 110. The axle 220 can be rotatably arranged on the frame body 110 along the axial line thereof, and the frame body 110 is fixedly arranged in the axial direction relative to the axle 220, so as to realize that the axle 220 can drive the running wheel 210 to rotate. The frame body 110 has a first displacement space for the running wheel 210 to move along the axial direction of the axle 220 and to be separated from the second end of the axle 220, and has a second displacement space for the running wheel 210 to be separated from the frame body 110 from the lower side of the frame body 110. In this way, after the running wheel 210 is separated from the axle 220, the running wheel 210 can be vertically separated from the frame body 110, so that the running wheel 210 can be dismounted and replaced without disassembling, the time for replacing the running wheel 210 is saved, and the efficiency of replacing the running wheel 210 is improved.

[0051] As shown, Figure 1As shown, the frame assembly 100 further comprises an auxiliary running wheel set and an air spring 130, wherein the auxiliary running wheel set comprises guide wheels 121 mounted at the four corners of the frame body 110 for guiding during turning; the frame body 110 is provided with auxiliary wheels 122 on the two end beams 112 axially parallel to the wheel shaft 220, for assisting the running wheels 210 to travel and continuing to support the vehicle body when the running wheels 210 are out of tire, etc., to provide auxiliary protection; the bottom ends of the two side vertical beams of the frame body 110 are provided with stabilizing wheels 123 for preventing the monorail train from tilting and overturning during operation, to ensure safe driving; and the top end of the middle vertical beam of the frame body 110 is provided with the air spring 130, which can buffer and support the vehicle body.

[0052] As shown in the drawings, Figures 6-12 The fastening assembly 500 comprises a wedge block 510, a connecting bolt (not shown in the drawings), a self-locking nut 520 and a washer 530. The wedge block 510 is provided with a clamping structure and a connecting hole 512, and the clamping piece 600 is used to detach the wedge block 510 by cooperating with the clamping structure of the wedge block 510; the connecting bolt passes through the connecting hole 512, the hub 230 and the rim of the running wheel 210, to detachably fix and connect the hub 230 and the running wheel 210; the washer 530 is sleeved on the connecting bolt, and the self-locking nut 520 is threadedly connected with the connecting bolt; the self-locking nut 520, the washer 530 and the wedge block 510 are sequentially abutted and fixedly connected; during the process of detaching the fastening assembly 500, the connecting bolt is first screwed out, and then the wedge block 510 and the self-locking nut 520 and the washer 530 connected with the wedge block 510 are synchronously taken out by cooperating the clamping piece 600 with the clamping structure, to realize that the fastening assembly 500 is separated from the running wheel 210 and the hub 230.

[0053] In some embodiments, as shown in the drawings, Figure 8 The washer 530 is a double-stacked self-locking washer, which cooperates with the self-locking nut 520 to further ensure the stability of the connection between the connecting bolt and the running wheel 210 and the hub 230.

[0054] As shown in the drawings, Figures 9-12 The clamping structure is a clamping hole 511, and the clamping piece 600 can be detachably fixedly cooperated with the clamping hole 511, to realize that the clamping piece 600 stably detaches the wedge block 510.

[0055] Since the wedge block 510 is small in size, to further ensure the stability of the wedge block 510 during the process of moving out after the clamping piece 600 is fixedly cooperated with the clamping hole 511, the clamping hole 511 is two, and the clamping piece 600 is also two, and the clamping piece 600 corresponds to the clamping hole 511 one by one, so that the area of the connection between the clamping piece 600 and the wedge block 510 is increased, to ensure the stability of the process of detaching the wedge block 510.

[0056] In some embodiments, the clamping hole 511 is a threaded hole, and the end of the clamping piece 600 matched with the clamping hole 511 is provided with external threads matched with the threaded hole, so as to ensure the stable connection between the clamping piece 600 and the clamping hole 511, and further ensure the stability of the dismounting process of the wedge block 510.

[0057] In other embodiments, the clamping hole 511 is a through hole, and the end of the clamping piece 600 matched with the clamping hole 511 is provided with a rubber layer and can be matched with the clamping hole 511 through the rubber layer, so as to save the matching time of the clamping piece 600 and the clamping hole 511, and further improve the dismounting efficiency of the wedge block 510.

[0058] Since the fastening assembly 500 is away from the edge of the running wheel 210 by a certain distance, in order to further facilitate the dismounting of the fastening assembly 500 by the clamping piece 600, as shown in Figure 6 the end of the clamping piece 600 matched with the clamping structure of the wedge block 510 is a first end, and the end of the clamping piece 600 away from the wedge block 510 is a second end. In the case that the clamping piece 600 is matched with the clamping structure, the second end of the clamping piece 600 is away from the hub 230 farther than the wedge block 510, that is, the clamping piece 600 has a certain length, so that the second end of the clamping piece 600 is closer to the operating end of the worker, so that the worker can dismount the wedge block 510 through the clamping piece 600 more conveniently, thereby further improving the dismounting efficiency of the fastening assembly 500.

[0059] In order to further facilitate the operation of the clamping piece 600, in some embodiments, as shown in Figure 6 and Figure 12 the second end of the clamping piece 600 away from the fastening assembly 500 is provided with a handle 610, so that the clamping piece 600 is more convenient to hold and can be operated more stably, thereby further ensuring the stability of the dismounting process of the fastening assembly 500.

[0060] Of course, in other embodiments, the clamping piece 600 can not be provided with a handle, and the embodiments of the present application do not limit this.

[0061] After the fastening assembly 500 is dismounted, in order to ensure that the running wheel 210 can be separated from the axle 220 and the frame body 110, the frame body 110 is improved in the embodiments of the present application.

[0062] As shown in Figure 2As shown, the frame body 110 comprises a connecting beam 114, a side beam 111, an end beam 112 and a middle beam 115. The connecting beam 114 is in rotation cooperation with the wheel shaft 220, and the connecting beam 114 is distributed on one side of the walking wheel 210 and corresponds to the gear box 400. Specifically, the connecting beam 114 is provided with a bearing seat 1141 to support the rotation of the wheel shaft 220, and the first end of the wheel shaft 220 is connected with the gear box 400 through the bearing seat 1141, so as to ensure the stability of the wheel shaft 220 during transmission.

[0063] As shown in Figure 2 , the end beam 112 and the middle beam 115 are parallel to the axial direction of the wheel shaft 220. In one frame body 110, the connecting beam 114 is two, and the two connecting beams 114 are located on both sides of the frame body 110 in the axial direction of the wheel shaft 220, and the two connecting beams 114 are located on both sides of the middle beam 115. The side beam 111 corresponds to the connecting beam 114 one by one, and the end beam 112 corresponds to the connecting beam 114 one by one. In this way, in one frame body 110, there are two parts distributed symmetrically, so that the frame body 110 can ensure balanced force after being connected with the walking wheel assembly 200, the driver 300 and the gear box 400, so as to realize stable driving of the vehicle body.

[0064] As shown in Figure 2 , the frame body 110 also has a placing table 113 for placing the driver 300 and the gear box 400, so as to reduce the radial load of the output shaft of the gear box 400 and ensure the stability of the transmission of the gear box 400.

[0065] As shown in Figure 3 , Figure 5 , Figure 13 and Figure 14 , the end beam 112, the middle beam 115, the connecting beam 114 and the side beam 111 form a containing space for containing the walking wheel 210, a first space for the walking wheel 210 to move along the axial direction of the wheel shaft 220 and disengage from the wheel shaft 220, and a second space for the walking wheel 210 to disengage from the frame body 110 from the lower side of the frame body 110.

[0066] As shown in Figure 13As shown, the traveling wheel 210 has disengaged from the axle 220 in the direction of the arrow shown in the figure. The distance between the connecting beam 114 and the side beam 111 is sufficient to allow the traveling wheel 210 to move axially along the axle 220 until it disengages from the axle 220. Furthermore, the end beam 112 and the middle beam 115 will not interfere with the movement of the traveling wheel 210 along the axle 220, so as to realize the disengagement of the traveling wheel 210 from the axle 220.

[0067] It should be noted that, Figure 13 The arrow in the diagram indicates one of the axial directions of the axle 220.

[0068] In the straddle-type monorail train bogie provided in the embodiments of this application, in order to meet the limited axial dimensions of the bogie, such as Figure 1 As shown, the first gap between the second end of the wheel axle 220 and the side beam 111 is greater than the second gap between the running wheel 210 and the side beam 111. This shortens the distance the running wheel 210 moves axially along the wheel axle 220, making the bogie more compact.

[0069] like Figure 14 As shown, after the traveling wheel 210 disengages from the axle 220, the guide wheel 121 near the side beam 111 is removed, so that the traveling wheel 210 disengages from the frame body 110 in the direction of the arrow shown in the figure, thus achieving the disassembly of the traveling wheel 210. It should be noted that... Figure 14 The arrow in the image points in the direction of vertical downwards.

[0070] To ensure that the running wheels 210 can detach from the frame body 110, such as Figure 3 and Figure 5 As shown, the side of the end beam 112 closest to the traveling wheel 210 is a vertical plane, and the side of the middle beam 115 closest to the traveling wheel 210 is a vertical plane. This ensures that the end beam 112 and the middle beam 115 will not interfere with the movement of the traveling wheel 210 along the wheel axle 220, realizes that the traveling wheel 210 is detached from the frame body 110 in the vertical direction, and makes the frame body 110 more compact.

[0071] To maintain the strength of end beam 112, such as Figure 4 (The dashed lines in the figure are for illustrative purposes only and do not represent actual inclusion.) As shown, the end beam 112 includes a uniform width section 1121 and a width-gradient section 1122 that are distributed and fixedly connected from top to bottom in the vertical direction. The width of the width-gradient section 1122 gradually increases from the bottom end of the end beam 112 to the top end of the end beam 112. The width direction of the end beam 112 is perpendicular to the axial direction of the wheel axle 220, and the length direction is parallel to the axial direction of the wheel axle 220. This improves the strength of the end beam 112 and ensures the strength of the frame body 110.

[0072] The cross seat type monorail bogie provided by the embodiment of the application is used to replace and maintain the running wheel 210. First, the monorail train is parked on a maintenance work station to support the frame assembly 100 and the vehicle body. The connecting bolt in the fastening assembly 500 is screwed out, the clamping piece 600 is fixedly connected with the clamping hole 511 of the wedge block 510, then the wedge block 510 is sequentially moved out through the clamping piece 600, so that the running wheel 210 is separated from the wheel hub 230. First, the running wheel 210 is moved along the wheel shaft 220 to the second end of the wheel shaft 220 to be separated from the wheel shaft 220, then the guide wheel 121 close to the side beam 111 is disassembled, the running wheel 210 is separated from the frame body 110 along the vertical direction downward, so that the running wheel 210 is disassembled, the running wheel 210 is disassembled without being uncoupled, and the wheel replacement is implemented. The time for replacing the wheel is saved, and the efficiency of replacing the wheel is improved.

[0073] The embodiment of the application further provides a cross seat type monorail train, which comprises the cross seat type monorail bogie in the above embodiment.

[0074] Since the cross seat type monorail bogie has the above technical effects, and the cross seat type monorail train comprises the cross seat type monorail bogie, the cross seat type monorail train also has corresponding technical effects, which will not be described herein.

[0075] The above description of disclosed embodiments enables those skilled in the art to implement or use the application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the application.
