Bogie, adjustment method and transport vehicle

Abstract

The application discloses a bogie, a regulating method and a transport vehicle. The bogie comprises a frame, a wheel pair assembly installed on the frame and used for rolling cooperation with a track, a spring, a support connected with the frame through the spring, the support and the frame having a first vertical interval, a positioning wheel assembly installed on the support and used for rolling cooperation with a track beam, a vertical limiting assembly installed on the frame or the support and located in the first vertical interval, and the vertical limiting assembly and the frame or the support having a second vertical interval. When the body roll is greater than a design value, one side of the frame is lifted, the second vertical interval is gradually reduced after the frame is lifted, and the second vertical interval is reduced to 0. When the second vertical interval is reduced to 0, the vertical limiting assembly is in abutment with the frame and the support, so that overturning of the body is prevented. When the wheel climbs upward along the track, the climbing height of the wheel rim along the track is less than the minimum height of the wheel rim under the action of the vertical limiting assembly, so that climbing of the vehicle is avoided. In addition, when the wheel rim further increases the lateral displacement along the track if the vertical limiting assembly fails, the lateral limiting assembly is used, so that derailment of the vehicle is avoided. Therefore, the two measures are used to avoid derailment of the vehicle.

Description

Technical Field

[0001] This application belongs to the field of aerial rail technology, and in particular relates to a bogie, adjustment method and transport vehicle. Background Technology

[0002] Skyrail, professionally known as a "suspended monorail train," is a new type of medium- and low-capacity rail transit system. The Skyrail train car is suspended below the track beams, "flying" in the air, hence the name "sky train." It has advantages such as not occupying ground road rights and strong environmental adaptability, and serves both commuting and sightseeing functions.

[0003] The bogie of the monorail can connect the track beam and the car body located below the track beam, and can drive the car body to move along the extension direction of the track beam.

[0004] For certain complex application scenarios, such as environments with strong crosswinds, it is necessary to solve the problems of ensuring that the lateral roll of the transport vehicle is within the clearance limits and does not overturn, and how to ensure that the lateral movement of the transport vehicle is within the limits and does not derail. Summary of the Invention

[0022] A controller, electrically connected to both the vertical spacing detector and the vertical adjusting member; the controller controls the vertical adjusting member to act based on the detection value of the second vertical interval fed back by the vertical spacing detector, so that the detection value of the second vertical interval reaches the set value of the second vertical interval.

[0023] In some embodiments, the vertical adjusting member is installed on the frame, the vertical limiting component further includes a vertical adjusting pad, the vertical adjusting pad is disposed between the vertical adjusting member and the frame, and / or, disposed between the vertical adjusting member and the vertical limiting block.

[0024] In some embodiments, there is a first lateral interval between the frame and the track beam;

[0025] The bogie further includes a lateral limiting component installed on the frame, the lateral limiting component is located in the first lateral interval; there is a second lateral interval between the lateral limiting component and the track beam.

[0026] In some embodiments, the second lateral interval satisfies y1 < y < y2; where y is the second lateral interval, y1 = y11 + y12, y11 is the maximum lateral displacement of the wheel of the wheel set relative to the track, y12 is the maximum lateral displacement of the frame relative to the track; y2 = min(y21, y22), y21 is the minimum derailment distance of the wheel on the climbing rail side; y22 is the minimum derailment distance of the wheel on the non-climbing rail side.

[0027] In some embodiments, the lateral limiting component includes:

[0028] A lateral limiting stop has a second lateral gap with the track beam;

[0029] A lateral adjustment component is installed on the frame. The output end of the lateral adjustment component is connected to the lateral limit component. The lateral adjustment component drives the lateral limit stop to move laterally to adjust the second lateral interval.

[0030] In some embodiments, the lateral limiting component further includes:

If the detection value of the second vertical interval is not equal to the set value of the second vertical interval and / or the detection value of the second horizontal interval is not equal to the set value of the second horizontal interval, then the adjustment step is executed.

[0041] The adjustment step involves controlling the action of the vertical limiting component and / or the lateral limiting component based on the judgment result of the judgment step, and then executing the detection step again.

[0042] Thirdly, an embodiment of this application provides a transport vehicle including the bogie described in the first aspect.

[0043] The present invention has at least the following beneficial effects:

[0044] When the vehicle body rolls more than the design value, the gravitational torque of the vehicle body cannot balance the roll torque under the limited roll angle. The excess roll force on the vehicle body is transferred to the frame, causing one side of the frame to rise. After the frame rises, the second vertical interval gradually decreases until it decreases to 0. When it decreases to 0, the vertical limit component abuts against both the frame and the support, thereby preventing the frame from rising further and limiting the excessive roll of the vehicle body, thus preventing the vehicle body from overturning and ensuring the safety of transportation.

[0045] Furthermore, with this design, when the wheel lateral movement is large, the gap between the wheel and the track decreases from a positive value to 0, and then the wheel flange climbs up along the track. As the wheel climbs up along the track, the frame on the same side is raised. When the frame is raised to its maximum value (that is, when the vertical limit component is in contact with both the frame and the support), the amount of height the wheel flange climbs along the track is less than the minimum height of the wheel flange. This prevents the track from causing a larger lateral movement of the wheel, thus avoiding the vehicle from climbing the track (a type of derailment). This forms an anti-derailment measure to prevent the vehicle from derailing.

[0046] In addition, if the vertical limiting component fails and the lateral movement of the wheel increases further, the wheel flange climbs to the top surface of the rail, and the second lateral interval gradually decreases until it decreases to 0. When it decreases to 0, the lateral limiting component comes into contact with the rail beam, thereby preventing the wheel from continuing to move laterally, and thus preventing the vehicle from derailing (derailment is another way of derailment), forming another measure to prevent derailment.

[0062] In related technologies, bogies are prone to overturning. This application provides a bogie, an adjustment method, and a transport vehicle, which can at least partially solve the technical problem of bogies being prone to overturning.

[0063] This application is described below with reference to the accompanying drawings and specific embodiments:

[0064] like Figures 1 to 5 As shown, the bogie 100 includes a frame 110, a wheelset assembly 120, a spring assembly 130, a bracket 140, a positioning wheel assembly 150, and a vertical limiting assembly 160. The wheelset assembly 120 is mounted on the frame 110 for rolling engagement with the track 200; the bracket 140 is connected to the frame 110 via the spring assembly 130; the bracket 140 and the frame 110 have a first vertical gap; the positioning wheel assembly 150 is mounted on the bracket 140 for rolling engagement with the track beam 300; the vertical limiting assembly 160 is mounted on the frame 110 or the bracket 140 and is located within the first vertical gap; and the vertical limiting assembly 160 has a second vertical gap with the frame 110 or the bracket 140.

[0065] The wheelset assembly 120 is mounted on the frame 110, which supports the frame 110. The wheelset assembly 120 has various structures and may include components such as axles, wheels 121, and load-bearing saddles. Specifically, the wheelset assembly 120 rolls with the track 200 via wheels 121. The bracket 140 supports components such as the linear motor and the positioning wheel assembly 150. The positioning wheel assembly 150 may include components such as axles and positioning wheels. The circumferential surface of the positioning wheels of the positioning wheel assembly 150 rolls in contact with the track beam 300 located on top of the bogie 100, so that there is sufficient air gap between the linear motor and the track beam 300 to generate the required electromagnetic driving force.

[0066] The specific structures of the wheelset assembly 120, the positioning wheel assembly 150, the bracket 140, and the frame 110 are not limited in this application. Those skilled in the art can make adaptive designs according to specific circumstances, and the connection relationships between them are also known to those skilled in the art. For reference, see the utility model patent with patent publication number CN218340601U and the invention patent with patent publication number CN116552590 A. They will not be described in detail in this application.

[0067] The frame 110 and the support 140 are connected by a spring assembly 130, which exerts an upward force on the support 140. Under the action of the spring assembly 130, the positioning wheels of the positioning wheel assembly 150 are always in contact with the inner top wall of the track beam 300. Because the spring assembly 130 is elastic, it compresses and shortens under force. Therefore, in environments with strong crosswinds, one side of the frame 110 will rise towards the side closer to the support 140, causing it to overturn. In some embodiments, the frame 110 and the support 140 are also connected by a tie rod.

[0068] Vertically, there is a first vertical gap between the bracket 140 and the frame 110. The vertical limiting assembly 160 can be installed on either the frame 110 or the bracket 140. When the vertical limiting assembly 160 is installed, it is located within the first vertical gap. If the vertical limiting assembly 160 is installed on the frame 110, there is a second vertical gap between the vertical limiting assembly 160 and the bracket 140. If the vertical limiting assembly 160 is installed on the bracket 140, there is a second vertical gap between the vertical limiting assembly 160 and the frame 110.

[0069] With this design, when the car body 400 mounted on the frame 110 of the bogie 100 rolls under conditions such as severe crosswinds, and the roll is less than the design value, the gravitational torque of the car body 400 can balance the roll torque under the limited roll angle of the car body 400. At this time, the vertical limit assembly 160 does not function. When the roll of the vehicle body 400 exceeds the design value, the gravitational torque of the vehicle body 400 cannot balance the roll torque under the limited roll angle. The excess roll force on the vehicle body 400 is transferred to the frame 110, causing one side of the frame 110 to rise. After the frame 110 rises, the second vertical interval gradually decreases until it decreases to 0. When it decreases to 0, the vertical limiting assembly 160 abuts against both the frame 110 and the support 140, thereby preventing the frame 110 from rising further and limiting the excessive roll of the vehicle body 400, thus preventing the vehicle body 400 from overturning and ensuring the safety of transportation.

[0070] With the design of this application, when the lateral displacement of the wheel 121 is small, the vehicle is safe during operation and parking, and derailment will not occur. When the lateral displacement of the wheel 121 is large, the gap between the wheel 121 and the track 200 decreases from a positive value to 0, and then the wheel flange of the wheel 121 climbs upward along the track 200. When the wheel 121 climbs upward along the track 200, the same-side frame 110 will be lifted. When the frame 110 is lifted to the maximum value (that is, when the vertical limit component 160 abuts against both the frame 110 and the bracket 140), the climbing height of the wheel flange of the wheel 121 along the track 200 is less than the minimum height h of the wheel flange of the wheel 121, thereby preventing the track 200 from allowing a larger lateral displacement of the wheel 121, thus avoiding the vehicle from climbing the track (climbing the track is a form of derailment), forming a derailment prevention measure to prevent the vehicle from derailing.

[0071] The value of the second vertical interval can be adaptively set according to the first vertical interval, the dynamic deflection of the spring assembly 130, the dynamic deflection of the primary suspension spring 165, etc., and is not limited in this application. The second vertical interval should ensure that the spring assembly 130 has a certain deformation space and ensure that the vertical limit component 160 does not function during normal vehicle operation or parking. The second vertical interval should also ensure that it abuts against the bracket 140 and the frame 110 before the wheel flange of the wheel 121 reaches the top surface of the track 200, so as to prevent the wheel flange of the wheel 121 from climbing onto the top surface of the track 200 and causing derailment of the climbing track type.

[0072] H is the second vertical interval. The magnitude of the lifting height z0 of the wheel 121 caused by the second vertical interval is related to the minimum height h of the wheel flange of the wheel 121 and the dynamic deflection z1 of the primary suspension spring 165 of the frame 110. The relationship can be summarized as: z1 < z0 < h. The magnitude relationship between H and z0 can be determined by methods such as the graphical method. The method of the graphical method is as follows: As Figure 11 shown, after determining the value of z0, according to the structural layout of the bogie 100 and the requirement that the vertical limit component 160 abuts against both the frame 110 and the bracket 140 during the maximum roll of the car body 400, by measuring Figure 10 the gap between the bracket 140 and the vertical limit component 160 on the drawing of the car body 400 without rolling, the magnitude of the second vertical interval H is determined.

[0073] In some embodiments, in order to ensure that both sides of the bogie 100 in the running direction can be evenly stressed and prevent the bogie 100 from being distorted, the bogie 100 includes multiple vertical limit components 160, and the multiple vertical limit components 160 are respectively arranged on both sides of the frame 110 in the running direction and are located above the primary suspension spring 165 of the bogie 100.

[0074] The structure and installation of the primary spring 165 are known to those skilled in the art. It is disposed between the frame 110 and the wheelset assembly 120. Specifically, the primary spring 165 connects the frame 110 and the load-bearing saddle of the wheelset assembly 120, and can absorb shocks and vibrations.

[0075] In some embodiments, the bogie 100 has four primary springs 165 and four vertical limiting components 160, with two on each side of the frame 110 in the direction of travel, and each vertical limiting component 160 is located directly above each primary spring 165.

[0076] like Figure 5 As shown, in some embodiments, the vertical limiting assembly 160 includes a vertical limiting stop 161 and a vertical adjusting member 162. The vertical limiting stop 161 has a second vertical gap with the frame 110 or the bracket 140; the vertical adjusting member 162 is mounted on the frame 110 or the bracket 140, and its output end is connected to the vertical limiting stop 161; the vertical adjusting member 162 drives the vertical limiting stop 161 to move vertically to adjust the second vertical gap.

[0077] If the vertical adjustment component 162 is installed on the frame 110, there is a second vertical gap between the vertical limit stop 161 and the bracket 140; otherwise, there is a second distance between it and the frame 110. The output end of the vertical adjustment component 162 is connected to the vertical limit stop 161, which can drive the vertical limit stop 161 to rise or fall vertically and stop at the position after movement. With this design, the vertical position of the vertical limit stop 161 can be adjusted by controlling the movement of the vertical adjustment component 162, thereby adjusting the value of the second vertical gap. This allows the value of the second vertical gap to be adaptively adjusted according to different specific scenarios, facilitating the use of the bogie 100.

[0078] In some embodiments, the vertical stop 161 includes a stop support 1611 and a stop body 1612. The stop support 1611 has a mounting groove 1611a and is mounted on the output end of the vertical adjuster 162; the stop body 1612 is elastic and is mounted in the mounting groove 1611a and at least partially extends out of the mounting groove 1611a.

[0079] With this design, the limit stop body 1612, being elastic, can absorb some of the impact energy at the moment of contact between it and the bracket 140 or frame 110. This helps to reduce the direct impact of the limit stop body 1612 on the bracket 140 or frame 110, reducing the resulting vibration and noise, and contributing to a smoother and safer operation of the bogie 100. It should be noted that when the limit stop body 1612 can be compressed to the point where it does not extend beyond the mounting slot 1611a, the second vertical interval refers to the vertical interval between the limit stop support 1611 and the bracket 140 or frame 110. When the limit stop body 1612 is compressed to its limit, if it still extends beyond the mounting slot 1611a, then the second vertical interval refers to the vertical interval between the limit stop body 1612 and the bracket 140 or frame 110 when the limit stop body 1612 is compressed to its limit.

[0080] like Figure 5 As shown, in some embodiments, the vertical adjustment member 162 is mounted on the frame 110, and the limit stop body 1612 can be compressed to be completely located within the mounting groove 1611a. In these embodiments, the second vertical interval refers to the limit stop support 1611 and the bracket 140, i.e. Figure 5 H in the text.

[0081] In some embodiments, the vertical limiting assembly 160 further includes a vertical spacing detector 170 and a controller. The vertical spacing detector 170 is mounted on the output end of the vertical adjustment member 162 or on the vertical limiting stop 161, and is used to detect the detection value of the second vertical interval. The controller is electrically connected to both the vertical spacing detector 170 and the vertical adjustment member 162. Based on the detection value of the second vertical interval fed back by the vertical spacing detector 170, the controller controls the vertical adjustment member 162 to operate so that the detection value of the second vertical interval reaches the set value of the second vertical interval.

[0082] Before the transport vehicle starts operating, the vertical spacing detector 170 detects the value of the second vertical spacing and sends it to the controller. The controller compares the detected value with the set value of the second vertical spacing. If they are not equal, a control signal is sent to the vertical adjustment component 162 based on the magnitude of the deviation. This causes the vertical adjustment component 162 to move the vertical limit stop 161, thereby adjusting the second vertical spacing so that the detected value equals the set value. With this design, the second vertical spacing can be automatically detected and adjusted before the transport vehicle starts operating, reducing the need for manual intervention, thus reducing downtime for maintenance and lowering maintenance costs. Furthermore, this design allows the detected value of the second vertical spacing to be sent to the controller in real time during transport, enabling real-time online detection of the second vertical spacing and contributing to improved vehicle safety.

[0083] In some embodiments, the vertical adjustment member 162 is mounted on the frame 110, and the vertical limiting assembly 160 further includes a vertical adjustment pad 175, which is disposed between the vertical adjustment member 162 and the frame 110, and / or between the vertical adjustment member 162 and the vertical limiting stop 161.

[0084] The vertical adjustment pad 175 can be positioned between the vertical adjustment component 162 and the frame 110, or between the vertical adjustment component 162 and the vertical limit stop 161. It should be noted that there are multiple vertical adjustment components 162. Increasing the number of vertical adjustment pads 175 can bring the vertical limit stop 161 closer to the bracket 140, thereby reducing the second vertical gap. Conversely, decreasing the number of vertical adjustment pads 175 can move the vertical limit stop 161 further away from the bracket 140, thereby increasing the second vertical gap. This design allows operators to manually adjust the second vertical gap by adding or removing the number of adjustment pads. This ensures effective adjustment of the second vertical gap even in the event of malfunctions or damage to components such as the vertical gap detector 170, controller, or vertical adjustment component 162, guaranteeing the stable operation and safety of the bogie 100 and preventing it from overturning.

[0085] In some embodiments, the vertical adjustment member 162 and the frame 110 are connected by bolts and nuts, and multiple vertical adjustment pads 175 are provided. The multiple vertical adjustment members 162 are stacked vertically between the vertical adjustment member 162 and the frame 110. Under the action of the bolts and nuts, the vertical adjustment member 162 and the frame 110 clamp the multiple vertical adjustment pads 175 located between them. When it is necessary to increase or decrease the number of vertical adjustment pads 175, the bolts and nuts can be removed.

[0086] When the vertical limiting component 160 fails, after the wheel flange of wheel 121 climbs to the top surface of track 200, wheel 121 still has the risk of derailment. In some embodiments, such as... Figure 3 and Figure 5 As shown, there is a first lateral gap between the frame 110 and the track beam 300; the bogie 100 also includes a lateral limiting assembly 180 installed on the frame 110, the lateral limiting assembly 180 being located in the first lateral gap; there is a second lateral gap between the lateral limiting assembly 180 and the track beam 300.

[0087] Laterally, there is a first lateral gap between the frame 110 and the track beam 300, and the lateral limiting assembly 180 is installed on the frame 110 and located within the first lateral gap. Laterally, there is a second lateral gap between the lateral limiting assembly 180 and the track beam 300. With this design, when the lateral movement of the wheel 121 is small, vehicle operation and parking are safe and derailment will not occur. However, when the lateral movement of the wheel 121 is large, the gap between the wheel 121 and the track 200 decreases from a positive value to 0, and the wheel flange of the wheel 121 climbs up the track 200. As wheel 121 climbs up track 200, the frame 110 on the same side is raised. When frame 110 is raised to its maximum value H, the upper surface of the limit stop support 1611 abuts against the lower surface of bracket 140. The amount of height the wheel rim of wheel 121 climbs up track 200 is less than the minimum height h of wheel rim, thus preventing track 200 from causing a larger lateral movement of wheel 121, thereby preventing the vehicle from climbing the track (a type of derailment), forming the first anti-derailment measure. If the vertical limit assembly 160 fails, after the wheel rim of wheel 121 climbs to the top surface of track 200, the second lateral interval between the lateral limit assembly 180 and the inner side of track beam 300 decreases until it decreases to 0. At this time, the inner side of the track beam 300 prevents excessive lateral displacement of the frame 110, which in turn prevents excessive lateral displacement of the wheel 121, thus preventing the wheel 121 from derailing (derailment is another way of derailment), thereby forming a second anti-derailment measure. Under the combined action of the vertical limiting component 160 and the lateral limiting component 180, this application forms two anti-derailment measures, effectively preventing the wheel 121 from derailing and ensuring transportation safety.

[0088] The specific value of the second lateral interval is related to the minimum derailment distance of the wheel 121 on the climbing side and the minimum derailment distance on the non-climbing side. Users can make adaptive designs according to specific circumstances, and no limitation is made in this application.

[0089] In some embodiments, the second lateral spacing satisfies y1 < y < y2; where y is the second lateral spacing, y1 = y11 + y12, y11 is the maximum lateral displacement of the wheel 121 of the wheel set 120 relative to the track 200, and y12 is the maximum lateral displacement of the frame 110 relative to the track 200, as Figure 9 shown; y2 = min(y21, y22), y21 is the minimum derailment distance of the wheel 121 on the climbing rail side; y22 is the minimum derailment distance of the wheel 121 on the non-climbing rail side, as Figure 8 shown. When actually determining y, manufacturing, installation and other errors usually need to be considered, and an appropriate safety margin should be left. In some embodiments, a safety margin of 3 mm to 5 mm is left.

[0090] In some embodiments, the lateral limit assembly 180 includes a lateral limit assembly 180 and a lateral adjuster 182. There is a second lateral spacing between the lateral limit assembly 180 and the track beam 300; the lateral adjuster 182 is installed on the frame 110, the output end of the lateral adjuster 182 is connected to the lateral limit assembly 180, and the lateral adjuster 182 drives the lateral limit stop 181 to move laterally to adjust the second lateral spacing.

[0091] The lateral adjuster 182 drives the lateral limit stop 181 to move laterally and stops at the position after movement. After such design, the position of the lateral limit stop 181 can be adjusted by controlling the movement of the lateral adjuster 182, thereby adjusting the value of the second lateral spacing, so that the value of the second lateral spacing can be adaptively adjusted according to different specific scenarios, facilitating the use of the bogie 100.

[0092] In some embodiments, the lateral limit assembly 180 further includes a lateral spacing detector 185 and a controller. The lateral spacing detector 185 is disposed on the lateral limit assembly 180 or the output end of the lateral adjuster 182, and the lateral spacing detector 185 is used to detect the detected value of the second lateral spacing; the controller is electrically connected to both the lateral spacing detector 185 and the lateral adjuster 182; the controller controls the action of the lateral adjuster 182 based on the detected value of the second lateral spacing fed back by the lateral spacing detector 185, so that the detected value of the second lateral spacing reaches the set value of the second lateral spacing.

[0093] The lateral spacing detector 185 detects the value of the second lateral spacing and sends it to the controller. The controller compares the detected value with the set value of the second lateral spacing. When they are not equal, a control signal is sent to the lateral adjustment component 182 based on the magnitude of the deviation. This causes the lateral adjustment component 182 to move the lateral limit stop 181, thereby adjusting the detected value of the second lateral spacing until it equals the set value. This design allows for automatic detection and adjustment of the second lateral spacing, reducing the need for manual intervention, thus minimizing downtime and maintenance costs. Furthermore, this design allows the detected value of the second lateral spacing to be sent to the controller in real time during transport, enabling real-time online detection and improving vehicle safety.

[0094] In some embodiments, the lateral limiting assembly 180 includes a mounting base 1811 and a limiting wheel 1812. The mounting base 1811 is mounted on the output end of the lateral adjusting member 182; the limiting wheel 1812 is rotatably connected to the mounting base 1811, and there is a second lateral gap between the limiting wheel 1812 and the track beam 300.

[0095] The lateral adjustment component 182 drives the mounting base 1811 to move laterally, thereby causing the limiting wheel 1812 on the mounting base 1811 to move laterally. When the limiting wheel 1812 moves to contact the track beam 300, it prevents the wheel 121 from continuing to move laterally, thus preventing the wheel 121 from derailing. It should be noted that the axis of the limiting wheel 1812 is set vertically. With this design, when the limiting wheel 1812 moves to contact the track beam 300, the circumferential surface of the limiting wheel 1812 contacts the track beam 300, and there is rolling contact between the limiting wheel 1812 and the track beam 300, which helps to reduce the friction between the limiting wheel 1812 and the track beam 300 and improve the stability of the transport vehicle.

[0096] In some embodiments, the lateral limiting assembly 180 further includes a lateral adjusting pad 190; the lateral adjusting pad 190 is disposed between the lateral adjusting member 182 and the frame 110, and / or, disposed between the lateral adjusting member 182 and the lateral limiting stop 181.

[0097] The lateral adjustment pad 190 can be positioned between the lateral adjustment component 182 and the frame 110, or between the lateral adjustment component 182 and the mounting base 1811. It should be noted that there are multiple lateral adjustment components 182. Increasing the number of lateral adjustment pads 190 can bring the lateral limit stop 181 closer to the track beam 300, thereby reducing the second lateral gap. Conversely, decreasing the number of lateral adjustment pads 190 can move the lateral limit stop 181 further away from the track beam 300, thereby increasing the second lateral gap. This design allows operators to manually adjust the second lateral gap by adding or removing the number of adjustment pads. This ensures effective adjustment of the second lateral gap even in the event of malfunction or damage to components such as the lateral gap detector 185, controller, or lateral adjustment component 182, guaranteeing the stable operation and safety of the bogie 100 and preventing derailment.

[0098] During the assembly of the bogie 100, the second vertical spacing can be adjusted to the set value by adding or subtracting the vertical adjustment pad 175, and the second lateral spacing can be adjusted to the set value by adding or subtracting the lateral adjustment pad 190.

[0099] In some embodiments, the lateral adjusting member 182 and the mounting base 1811 are connected by bolts and nuts, and multiple lateral adjusting pads 190 are provided. The multiple lateral adjusting members 182 are stacked laterally between the lateral adjusting member 182 and the mounting base 1811. Under the action of the bolts and nuts, the lateral adjusting member 182 and the mounting base 1811 clamp the multiple lateral adjusting pads 190 located between them. When it is necessary to increase or decrease the number of lateral adjusting pads 190, the bolts and nuts can be removed.

[0100] In some embodiments, the bogie 100 includes a plurality of lateral limiting components 180, which are disposed on both sides of the frame 110 in the direction of travel. With this design, lateral limiting components 180 are provided on both sides of the frame 110 in the direction of travel, limiting the movement of the frame 110 on both sides and improving the anti-derailment performance of the bogie 100.

[0101] In some embodiments, four lateral limiters are provided to form a 180, and two lateral limiters are provided on each side of the frame 110 in the direction of travel to form a 180.

[0102] Based on the same inventive concept, this application also provides a method for adjusting a bogie 100, including steps S100, S200 and S300.

[0103] S100, Detection step: Obtain the detection value of the second vertical interval and the detection value of the second horizontal interval;

[0104] S200, Judgment step: determine whether the detection value of the second vertical interval is equal to the set value of the second vertical interval, and determine whether the detection value of the second horizontal interval is equal to the set value of the second horizontal interval. If the detection value of the second vertical interval is not equal to the set value of the second vertical interval and / or the detection value of the second horizontal interval is not equal to the set value of the second horizontal interval, then execute the adjustment step.

[0105] S300, Adjustment step: Based on the judgment result of the judgment step, control the vertical limit component 160 and / or the lateral limit component 180 to move, and execute the detection step again.

[0106] In an embodiment where the bogie 100 includes a vertical adjuster 162, a vertical spacing detector 170, a controller, a lateral adjuster 182, and a lateral spacing detector 185, the lateral spacing detector 185 acquires the detection value of the second lateral spacing, the vertical spacing detector 170 acquires the detection value of the second vertical spacing, and the controller determines whether the detection value of the second lateral spacing is equal to the set value of the second lateral spacing. When the detection value of the second vertical spacing is not equal to the set value of the second vertical spacing, the controller sends a control signal to the vertical adjuster 162 according to the magnitude of the deviation, causing the vertical adjuster 162 to move the vertical limit stop 161, thereby adjusting the second vertical spacing so that the detection value of the second vertical spacing is equal to the set value of the second vertical spacing. When the detected value of the second lateral interval is not equal to the set value of the second lateral interval, the controller sends a control signal to the lateral adjustment member 182 according to the magnitude of the deviation, so that the lateral adjustment member 182 drives the lateral limit stop 181 to move, thereby adjusting the detected value of the second lateral interval so that the detected value of the second lateral interval is equal to the set value of the second lateral interval.

[0107] In some embodiments, after the bogie 100 is powered on, the controller is activated and the above-described adjustment method is performed.

[0108] In some embodiments, the adjustment of the second lateral spacing and the second vertical spacing is performed only before the bogie 100 is in operation, and is not performed during the operation of the bogie 100.

[0109] In some embodiments, during the operation of the bogie 100, the lateral spacing detector 185 and the vertical spacing detector 170 monitor the changes in the second lateral spacing and the second vertical spacing in real time, and the bogie control system issues a fault warning based on the detected abnormal gap conditions.

[0110] The lateral spacing detector 185 and the vertical spacing detector 170 can be distance sensors, etc., and are not limited in this application.

[0111] Based on the same inventive concept, this application also provides a transport vehicle including the aforementioned bogie 100. Since the vehicle includes the aforementioned bogie 100, it naturally possesses all the beneficial effects of the bogie 100, which will not be elaborated upon here.

[0112] In some embodiments, the transport vehicle also includes a vehicle body 400, which is mounted on and below the frame 110. The vehicle body 400 can carry goods, passengers, etc.
