Description

Technical Field

[0001] This application relates to rail vehicle manufacturing technology, and more particularly to a magnetic levitation traction bogie and a magnetic levitation traction vehicle. Background Technology

[0002] Maglev traction vehicles are a type of maglev engineering vehicle, mainly used for train traction within the depot and for emergency rescue traction.

[0003] Due to the steep gradient of maglev lines, significant traction force is required for emergency train rescue operations. The traction force of a maglev traction vehicle is equal to its total weight multiplied by the adhesion coefficient between the drive wheels and the track surface. Generally, the adhesion coefficient between the drive wheels and the track is relatively fixed; therefore, to provide sufficient traction force, the overall weight of the vehicle must be increased. However, the track's load-bearing capacity is limited. Therefore, maglev traction bogies in related technologies often employ multi-axle bogies. This results in a very heavy maglev traction vehicle, causing significant vibration and impact on the track during operation, leading to lower stability and reliability, and placing higher demands on its components. Summary of the Invention

The magnetic levitation traction bogie of this application can be formed by connecting several bogie units end to end. The weight of a single bogie unit is relatively light, which solves the problem of the large weight of the entire magnetic levitation traction vehicle, reduces the impact force on the track when the magnetic levitation traction vehicle is running, improves the smoothness and reliability of the operation, and reduces the requirements for its own components.

[0041] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, 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 some embodiments of this application, but not all embodiments.

[0042] Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0043] As described in the background section, the structure of the maglev traction bogie in the related technical solutions results in a large overall weight of the maglev traction vehicle, a large vibration impact on the track during operation, low stability and reliability, and high requirements for its own components.

[0044] In view of this, the embodiments of this application aim to provide a maglev traction bogie and a maglev traction vehicle. By setting up independently operable bogie units, the maglev traction bogie can be formed by connecting several bogie units end to end according to the actual traction force requirements, thus avoiding the waste of traction force. At the same time, the weight of a single bogie unit is relatively light, which solves the problem of the large overall weight of the maglev traction vehicle, reduces the impact force on the track during the operation of the maglev traction vehicle, improves the stability and reliability of the operation, and reduces the requirements for its own components.

[0045] The embodiments of this application will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can gain a more detailed understanding of the contents of this application.

[0047] Please refer to Figures 1-9 This embodiment provides a magnetic levitation traction bogie, comprising multiple bogie units 10 connected end-to-end. Each bogie unit 10 can operate independently or be connected to other bogie units 10 for integrated control. Each bogie unit 10 includes a frame 100, on which a traction device 200 is mounted. The traction device 200 includes two traction rods 210, which are used to connect to traction rods 210 on adjacent bogie units 10 or to connect to a coupler. When a traction rod 210 is connected to a traction rod 210 on an adjacent bogie unit 10, the two bogie units 10 can be combined into one unit for traction operations, thereby increasing the traction force. When a traction rod 210 is connected to a coupler, it can be connected to the towed vehicle, thereby applying traction force to the towed vehicle.

[0048] In this embodiment, the maglev traction bogie can be formed by connecting several bogie units 10 end to end according to the required traction force, thus avoiding the waste of traction force. At the same time, the weight of a single bogie unit 10 is relatively light, which solves the problem of the large overall weight of the maglev traction vehicle, reduces the impact force on the track during the operation of the maglev traction vehicle, improves the smoothness and reliability of operation, and reduces the requirements for its own components.

[0049] Please continue to refer to Figure 2 In one possible implementation, the traction rod 210 of this embodiment includes a connecting section 211, an adjusting section 212, and an mounting section 213. The adjusting section 212 is disposed between the connecting section 211 and the mounting section 213. The adjusting section 212 can adjust the distance between the connecting section 211 and the mounting section 213, thereby facilitating the connection or disconnection of the bogie unit 10 with other bogie units 10 or the towing vehicle by the operator, and enabling the traction rod 210 to be adapted to tow different types of trains.

[0050] Furthermore, in this embodiment, the adjusting section 212 has reverse external threads at both ends, and the connecting section 211 facing the adjusting section 212 and the mounting section 213 facing the adjusting section 212 both have internal threads. The adjusting section 212 is threadedly connected to both the connecting section 211 and the mounting section 213. When it is necessary to increase the distance between the connecting section 211 and the mounting section 213, for example, the adjusting section 212 can be rotated clockwise, and the distance between the connecting section 211 and the mounting section 213 will continuously increase under the action of the threaded engagement structure at both ends; and when it is necessary to decrease the distance between the connecting section 211 and the mounting section 213, for example, the adjusting section 212 can be rotated counterclockwise, and the distance between the connecting section 211 and the mounting section 213 will continuously decrease under the action of the threaded engagement structure at both ends.

[0051] In this embodiment, the end of the connecting section 211 facing away from the adjusting section 212 is provided with a connecting flange 2111. The connecting flange 2111 can be connected to the connecting flange 2111 of the traction rod 210 on another bogie unit 10, thereby combining the two bogie units 10 into one unit; or, the connecting flange 2111 can be connected to the coupler flange, thereby connecting the bogie unit 10 to the towed vehicle. In this embodiment, the traction rod 210 is rotatably mounted on the frame 100 so that the angle can be adjusted as needed. Optionally, the frame 100 is provided with a center pin 220, and the end of the mounting section 213 facing away from the adjusting section 212 is provided with a bushing 2131. The bushings 2131 of both traction rods 210 are sleeved on the center pin 220; that is, one traction rod 210 is located above the other traction rod 210.

[0052] Please continue to refer to Figures 3-6 In this embodiment, the frame 100 can be constructed from welded steel plates into a box-beam structure, including two opposing crossbeams 110 and a longitudinal beam 120. A groove 111 is formed in the middle of the crossbeam 110, recessed towards the longitudinal beam 120. Both ends of the longitudinal beam 120 are connected to the two grooves 111. Drive wheelsets 300 are connected to the bottom of each of the two crossbeams 110, and guide devices 400 are connected to both ends of each crossbeam 110. Batteries 500 are located on both sides of the longitudinal beam 120. The frame 100 also includes a motor controller 600 and an electrical interface 700. The motor controller 600 is located between the two batteries 500 and is communicatively connected to both batteries 500. The electrical interface 700 is located in the groove 111 of the crossbeam 110 or on the side wall of the crossbeam 110, which facilitates the passage of cables. At the same time, according to actual needs, external interfaces such as plugs or sockets can be selectively installed on any electrical interface 700 to form a unified external interface, which facilitates the connection between bogie units 10 and bogie units 10, and between bogie units 10 and the towed vehicle.

[0053] This embodiment integrates components such as the power wheelset 300, battery 500, motor controller 600, and electrical interface 700 on the frame 100. This ensures that a single bogie unit 10 can operate independently, or it can be connected to other bogie units 10 or the towing vehicle through the electrical interface 700. This enables the coordinated operation of multiple bogie units 10 or the output of traction force, improving the flexibility of the configuration. Adjustments can be made according to actual needs to avoid wasting excess traction force, while reducing the requirements for components and thus reducing costs.

[0054] Please continue to refer to Figure 7 In one possible implementation, the power wheelset 300 of this embodiment includes an axle 310, with running wheels 320 connected to both ends of the axle 310. An axle may be provided within the axle 310, with both ends of the axle connected to the running wheels 320. A brake 330 is also provided on the axle 310, positioned close to the running wheels 320 to provide braking force to the running wheels 320; the brake 330 may include, for example, a parking brake and a service brake. A drive unit 340 is provided in the middle of the axle 310, connected to the axle 310. The drive unit 340 may be connected to the axle via a transmission component to drive the rotation of the axle, thereby driving the running wheels 320 through the axle. The axle 310 located between the drive unit 340 and the brake 330 is also provided with a primary suspension interface 350. The primary suspension interface 350 is connected to the primary suspension 800. The axle 310 is connected to the crossbeam 110 through the primary suspension 800, thereby realizing the connection between the drive wheelset 300 and the frame 100.

[0055] Please continue to refer to Figure 8 In one possible implementation, the primary suspension 800 of this embodiment includes a primary swing arm 810, a primary rubber spring 820, a rubber joint 830, and a stop seat 840. The first end of the primary swing arm 810 has a first mounting hole, which is vertically oriented, and the primary rubber spring 820 is installed in the first mounting hole. The second end of the primary swing arm 810 has a second mounting hole, which is horizontally oriented, and the rubber joint 830 is installed in the second mounting hole; that is, the primary rubber spring 820 and the rubber joint 830 are perpendicular to each other. The stop seat 840 is installed in the middle of the primary swing arm 810.

[0056] In this embodiment, a primary rubber spring mounting port 112, a stop seat mounting plate 113, and a rubber joint connecting plate 114 are provided below the crossbeam 110. The end of the primary rubber spring 820 facing away from the primary swing arm 810 is installed in the primary rubber spring mounting port 112. The end of the stop seat 840 facing away from the primary swing arm 810 is fixedly connected to the stop seat mounting plate 113. The rubber joint 830 is fixedly connected to the rubber joint connecting plate 114. Through the above structure, this embodiment realizes the connection between the primary suspension 800 and the frame 100.

[0057] A U-bolt fastener 850 is also fitted on the primary suspension arm 810. The U-bolt fastener 850 is located on both sides of the primary rubber spring 820 and is fixedly connected to the primary mounting interface 350. Through the above structure, this embodiment realizes the connection between the primary suspension 800 and the drive wheelset 300.

[0058] Please continue to refer to Figures 3-6 In this embodiment, a support beam 130 is also provided between the two crossbeams 110. The battery 500 is installed on the support beam 130. The crossbeams 110 and the support beam 130 are connected by a connecting beam 140. The setting of the support beam 130 and the connecting beam 140 not only improves the overall strength of the frame 100, but also provides sufficient support for the battery 500, thereby maintaining the structural stability of the bogie unit 10.

[0059] In this embodiment, the connecting beam 140 is provided with two opposing battery fixing plates 141. The battery fixing plates 141 can be made of parts such as angle steel. The battery fixing plates 141 have multiple through holes. The battery 500 is installed between the two battery fixing plates 141 and is connected and fixed to the battery fixing plates 141 by fasteners such as screws. Reinforcing ribs can also be welded between the battery fixing plates 141 and the connecting beam 140.

[0060] Please continue to refer to Figure 9 In one possible implementation, the guide device 400 of this embodiment includes an upper support 410 and a lower support 420, which are hinged together. For example, the upper support 410 can be hinged to the lower support 420 via a pin or other component, thereby allowing the lower support 420 to rotate relative to the upper support 410. A pressure adjusting device 430 is also provided between the upper support 410 and the lower support 420. The pressure adjusting device 430 includes a spring and a guide rod. One end of the guide rod is hinged to the upper support 410, and the other end of the guide rod passes through the lower support 420. The spring is sleeved on the outside of the guide rod and abuts against the lower support 420.

[0061] In this embodiment, guide wheels 440 are provided on both sides of the lower support 420. The guide wheels 440 can abut against the track, thereby ensuring that the bogie unit 10 has good curve handling performance. A safety wheel 450 is also provided at the end of the lower support 420 opposite to the upper support 410.

[0062] In this embodiment, the upper support 410 is provided with a guide connecting plate 460 at one end away from the lower support 420, and the crossbeam 110 is provided with a guide fixing plate 115 corresponding to the guide connecting plate 460. The guide device 400 is connected to the guide fixing plate 115 on the crossbeam 110 through the guide connecting plate 460, thereby realizing the connection and fixation between the guide device 400 and the frame 100.

[0063] This embodiment also provides a maglev traction vehicle, including a vehicle body, with a maglev traction bogie as described in the above embodiment located below the vehicle body.

[0064] Because the maglev traction vehicle in this embodiment uses the maglev traction bogie described above, several bogie units can be connected end-to-end according to the actual traction force requirements, avoiding waste of traction force. At the same time, the weight of a single bogie unit is relatively light, solving the problem of the large overall weight of the maglev traction vehicle, reducing the impact force on the track during operation, improving the stability and reliability of operation, and reducing the requirements for its own components.
