[0029] The core of this application is to provide a suspension controller and a maglev train, so that a suspension controller and a main circuit can control at least one suspension electromagnet, reducing the number and weight of suspension controllers in traditional maglev vehicles and simplifying the layout and control of the suspension controller.

[0030] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0031] The present application provides a suspension controller, as shown in FIG1 , which is applied to a maglev train and includes:

[0032] Main circuit, control circuit 17, drive circuit 14, at least two power modules 16;

[0033] The input end of the main circuit is connected to the vehicle power supply, and the output end of the main circuit is connected to the power module 16; the input end of the control circuit 17 is respectively connected to the sensor and the vehicle control unit, and the output end of the control circuit 17 is respectively connected to each power module 16 through the drive circuit 14, and each power module 16 is connected to the corresponding suspension electromagnet;

[0034] The sensor is used to collect the actual voltage of the main circuit and the actual current applied by each suspension electromagnet;

[0035] The control circuit 17 is used to output a control signal to the drive circuit 14 according to the vehicle control unit signal, the actual voltage and the actual current, so that the drive circuit 14 drives each power module 16 to output a control current to the corresponding suspension electromagnet.

[0036] According to the above, the present application provides a new type of suspension controller suitable for maglev trains. The design of this suspension controller is intended to solve some problems existing in traditional maglev vehicles. In traditional vehicles, each suspension point needs to be equipped with a separate suspension controller, resulting in a large number of suspension controllers, which brings complexity and inconvenience to the vehicle chassis equipment layout, electrical wiring, power supply and networking, and system control. In addition, the large number of suspension controllers occupies a large amount of vehicle chassis space, and the installation of chassis cables, brake lines and their accessories is limited. The above problems increase the cost of the vehicle and also increase the difficulty of design and construction. In addition, the total weight of the traditional suspension controller is relatively large, which is not conducive to the lightweight design and passenger carrying capacity improvement of the maglev vehicle.

[0037] To address the aforementioned issues, the novel suspension controller disclosed in this application utilizes a novel design and layout. This suspension controller includes a main circuit, a control circuit 17, a drive circuit 14, and at least two power modules 16. The input of the control circuit 17 is connected to the sensor and the vehicle control unit, respectively, while the output of the control circuit 17 is connected to each power module 16 via the drive circuit 14. Each power module 16 is connected to its corresponding suspension electromagnet.

[0038] The sensor is used to collect the actual voltage of the main circuit and the actual current applied by each levitation electromagnet. Based on the vehicle control unit signal, the actual voltage and current, the control circuit 17 outputs a control signal to the drive circuit 14, which drives each power module 16 to output a control current to the corresponding levitation electromagnet.

[0039] In other words, in this new type of suspension controller, sensors are used to collect the actual current applied by the suspension electromagnets and the actual voltage of the main circuit. Based on this data and signals from the vehicle control unit, the control circuit 17 outputs corresponding control signals to the drive circuit 14. The drive circuit 14 is connected to the power module 16, which outputs the appropriate control current to the corresponding suspension electromagnet.

[0040] In this application, the control circuit 17 can obtain status information for each suspension point by connecting to sensors and the vehicle control unit. Therefore, the suspension controller can reduce the number of required suspension controllers, thereby reducing costs. Due to the reduced number of suspension controllers, the suspension controller also occupies less space on the vehicle chassis, making it easier to install cables, pipes, and accessories.

[0041] In other words, by reducing the number of suspension controllers, this new type of suspension controller simplifies the complexity and inconvenience of maglev vehicle underframe equipment layout, electrical wiring, power supply and networking, and system control. It also solves the installation challenges of underframe cables, brake lines, and their accessories caused by an excessive number of suspension controllers. Furthermore, the new suspension controller's low weight contributes to the lightweight design of maglev vehicles and increases their passenger capacity.

[0042] As shown in FIG2 , in one embodiment, the control circuit 17 includes a main control circuit 17 and at least one backup control circuit 17 . The input end of the main control circuit 17 is respectively connected to the input end of the backup control circuit 17 , the sensor, and the vehicle control unit. The output end of the main control circuit 17 is connected to the output end of the backup control circuit 17 and is respectively connected to each power module 16 through the drive circuit 14 .

[0043] The main control circuit 17 is used to output a control signal to the drive circuit 14 according to the vehicle control unit signal, actual voltage and actual current when it is working normally, so that the drive circuit 14 drives each power module 16 to output a control current to the corresponding suspension electromagnet;

[0044] The backup control circuit 17 is used to output a control signal to the drive circuit 14 according to the vehicle control unit signal, actual voltage and actual current when the main control circuit 17 works abnormally, so that the drive circuit 14 drives each power module 16 to output a control current to the corresponding suspension electromagnet.

[0045] In one embodiment, the suspension controller is disposed in a box 1 , which is mounted on a frame of a maglev train, and a rectangular groove is provided on one side of the box 1 .

[0046] This embodiment describes the structure of a suspension controller. The suspension controller is installed within a box 1 on the frame of a maglev train. One side of the box 1 has a rectangular groove. This design resolves the conflict between the underframe equipment and the suspension controller in the prior art.

[0047] By adopting this suspension controller structure, the undercarriage equipment no longer needs to be suspended, thus eliminating the suspension controller's space occupation and the associated layout and installation challenges. Furthermore, by integrating the suspension controller into the vehicle frame, this design reduces vehicle costs. This innovative suspension controller structure can further enhance the performance and reliability of medium- and low-speed maglev vehicles.

[0048] In one embodiment, the box body 1 is an aluminum box body.

[0049] In this embodiment, the external structure of the suspension controller is a housing 1 made of aluminum. This housing design offers several advantages. First, the aluminum housing 1 is relatively lightweight, which reduces the overall weight of the maglev train, thereby improving operational efficiency and reducing energy consumption. Second, aluminum's excellent thermal conductivity effectively dissipates heat, ensuring the stability and reliability of the suspension controller during operation. Furthermore, aluminum's excellent corrosion resistance reduces the frequency of equipment maintenance and replacement.

[0050] Regarding the specific structure of the housing 1, it can also be a one-piece cast aluminum or comprised of an aluminum frame. Cast aluminum is a process where molten aluminum is poured directly into a mold for casting. The resulting housing 1 possesses integrity and rigidity, enhancing structural stability and shock resistance. The aluminum frame can be assembled and adjusted as needed, providing greater flexibility to accommodate suspension controllers of various sizes and shapes.

[0051] In summary, the design of the aluminum box 1 described in this embodiment is superior in the suspension controller of a maglev train, can improve the performance and reliability of the system, and reduce the overall cost.

[0052] In one embodiment, the box body 1 is provided with a plurality of screw holes 102 , and the screw holes 102 are used to install components included in the suspension controller.

[0053] In this embodiment, the housing 1 of the suspension controller is provided with a plurality of screw holes 102 for mounting components included in the suspension controller, such as filters. This means that various components of the suspension controller can be mounted on the housing 1 of the suspension controller via the screw holes 102. For example, components such as filters can be mounted on the housing 1 by fastening them to the screw holes 102.

[0054] This design effectively solves problems encountered in existing technologies. Traditionally, components in suspension controllers are mounted using welded nuts and / or brackets, hindering structural simplification, weight reduction, and cost reduction. However, by adding screw holes 102 to the housing 1 and mounting the suspension controller components therein, not only can the components be secured but additional mounting components can also be avoided.

[0055] This design allows the key components of the suspension controller for low- and medium-speed maglev vehicles to be installed close to the inner wall of the housing 1, improving space utilization, reducing the size of the suspension controller, and minimizing the space occupied by the chassis. It also provides more flexible installation options, facilitating the installation and adjustment of the suspension controller equipment, and simplifying the design and installation of vehicle cables and brake lines. Ultimately, this suspension controller design can reduce vehicle costs and improve design and construction efficiency.

[0056] In one embodiment, the box body 1 is further provided with a heat dissipation rib 103 , which is provided on any side of the box body 1 . The heat dissipation rib 103 is a strip-shaped rib structure protruding from the surface of the box body 1 .

[0057] In this embodiment, the housing 1 is further provided with heat dissipation ribs 103, located on either side of the housing 1. These ribs 103 are strip-shaped ribs protruding from the surface of the housing 1. In the design of medium- and low-speed maglev vehicles, the suspension controller, as a critical component, generates a certain amount of heat. To ensure proper operation of the suspension controller, heat dissipation is necessary to prevent overheating and equipment failure.

[0058] Therefore, the design of the suspension controller housing 1 incorporates heat dissipation ribs 103. In this embodiment, heat dissipation ribs 103 are strip-shaped ribs protruding from the surface of the housing 1, increasing the surface area of ​​the housing 1 and improving heat dissipation. Heat dissipation ribs 103 can be made of a metal material with excellent thermal conductivity, quickly transferring heat generated by the suspension controller to the surface of the housing 1. The extended shape of the heat dissipation ribs 103 effectively dissipates the heat.

[0059] In summary, this embodiment effectively controls the temperature of the suspension controller by providing heat dissipation ribs 103 having a strip-shaped rib structure on the housing 1, thereby improving its performance and reliability. This design provides better heat dissipation in applications involving medium- and low-speed maglev vehicles and prevents damage and malfunctions of the suspension controller caused by overheating.

[0060] In one embodiment, two handles 104 are further provided on the box body 1, and the distance between the plane formed by the two handles 104 and the plane where the center of gravity of the box body 1 is located is within a preset range.

[0061] The two handles 104 in this embodiment are located on the side of the box body 1, and the distance between the plane formed by them and the plane where the center of gravity of the box body 1 is located is within a preset range. The purpose of this design is to provide convenient installation and maintenance of the suspension controller. By arranging the handles 104 on the side of the box body 1, the operator can more easily grasp and control the suspension controller. Moreover, placing the handles 104 at a position at an appropriate distance from the plane where the center of gravity of the box body 1 is located can better balance the weight distribution of the box body 1, thereby facilitating operation and maintenance, and effectively preventing overturning due to obvious torque imbalance during transportation. At the same time, it can reduce the impact of force on the human hand when the overturning operation is required, thereby reducing the risk of damage to personnel / equipment caused by imbalance.

[0062] In one embodiment, the housing 1 is further provided with a plurality of heat sinks 106 . The heat sinks 106 are provided in the rectangular grooves, and the power module 16 in the suspension controller is adjacent to the heat sinks 106 .

[0063] In this embodiment, the function of the heat sink 106 is to dissipate the heat generated by the controller and maintain the normal operating temperature of the suspension controller. Since the suspension controller needs to process a large amount of current and power, a large amount of heat energy is generated during operation. If the heat is not dissipated in time, the temperature of the suspension controller will rise, which may lead to performance degradation, damage or even failure. The heat sink 106 is usually made of a material with high thermal conductivity, such as aluminum alloy. They quickly transfer heat to the surrounding environment through large-area contact with the frame of the maglev train to keep the temperature of the suspension controller within an acceptable range. The design of the rectangular groove can increase the contact area between the heat sink 106 and the frame, thereby improving the heat dissipation effect.

[0064] The power module 16 is a key component in the suspension controller. It rapidly switches the output suspension current to generate the appropriate electromagnetic force between the suspension electromagnet and the track. During operation, the power module 16 generates a significant amount of heat, which requires proper heat dissipation to ensure proper operation. Mounting the power module 16 adjacent to the heat sink 106 effectively transfers heat to the heat sink 106, maintaining the power module 16 temperature within a safe range.

[0065] Specifically, the base surface of the heat sink 106 faces the inside of the box body 1, forming the inner wall of the box body 1, and the fins of the heat sink 106 face the outside of the box body 1; the base surface of the large heat sink 106 is in close contact with the heat dissipation surface of the power module 16, and the middle interface is a heat-conducting material, which accelerates the heat dissipation of the power module 16 above it; the large heat sink 106 is perpendicular to the base surface of the radiator, and the longest dimension direction is perpendicular to the external connector mounting surface, which is convenient for utilizing the vehicle's running wind and the heat dissipation fan to exchange heat with the outside.

[0066] In general, this embodiment provides an effective heat dissipation method by installing the heat sink 106 on the housing 1 of the suspension controller, which can keep the temperature of the suspension controller within a safe range and ensure its normal operation and long-term reliability.

[0067] In one embodiment, threaded holes and light holes are provided on the box body 1 and the internal components of the suspension controller, and after the cable tie seat is installed, it is convenient to tie the wire harness to fix the components.

[0068] In one embodiment, a lifting lug 105 is further provided on the box body 1 , and an end surface of the lifting lug 105 is parallel to and at a certain distance from the surface of the box body 1 provided with the rectangular groove.

[0069] In this embodiment, a lifting lug 105 is provided on the housing 1. The end surface 105-A of the lifting lug 105 is parallel to and spaced a certain distance from the surface 105-B of the housing 1 where the rectangular groove is located, forming a sunken installation structure. This design allows for the installation of vehicle electrical cables and brake piping components within the space created by the height difference after the suspension controller is suspended by the lifting lug 105.

[0070] Specifically, the suspension controller is installed via the lugs 105, creating a certain height difference between the suspension controller and the maglev train frame. This height difference is fully utilized to install the vehicle's electrical cables and brake piping components, thereby reducing the design and construction difficulty of arranging other equipment on the underframe and installing the vehicle's cables and brake piping.

[0071] This sunken mounting structure not only improves underframe space utilization but also reduces the number of C-slots and weld nuts required for maglev vehicles, meeting the requirements for lightweighting, miniaturization, and cost reduction. This design also makes the suspension controller more convenient to install without interfering with the layout of other underframe equipment, reducing vehicle costs.

The mounting surface of the mounting bracket 8 is parallel to the output The mounting surface of the output reactor 10 divides the space therein into two layers, one layer is installed with the current sensor 6, the discharge resistor 9, and the output reactor 10, and the other layer is installed with the support capacitor 11; the power devices of the power module 16 are installed side by side, and the arrangement direction is parallel to the longest dimension direction of the large heat sink 106 fins; the busbar 12 is electrically connected to the support capacitor 11 and the absorption capacitor 15; the drive board 14 and the voltage sensor 13 are stacked and installed on the side of the non-mounting surface of the power module 16 and the absorption capacitor 15 through a mechanical structure to make full use of the space; the control circuit 17 and the control power supply 18 are key weak current and control components, and their location is on the side away from the strong current parts such as the filter 3 and the output reactor 10 to avoid the electromagnetic compatibility impact between strong and weak currents.
