Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] The core of this invention is to provide a suspended maglev vehicle with the suspension frame module placed outside the track, which allows for timely inspection and maintenance of the suspension frame module without returning to the depot.

[0023] The suspended maglev vehicle provided by this invention includes: a suspended vehicle 1, a track system 3, and a traction system 2. Please refer to [reference needed]. Figure 1 .

[0024] Please refer to Figure 2 , Figure 3The track system 3 includes a track beam 301 and an I-shaped track beam 304. The I-shaped track beam 304 includes a first transverse part 3041, a second transverse part 3043, and a vertical part 3042 connected in sequence. The transverse width of the first transverse part 3041 is greater than the transverse width of the second transverse part 3043.

[0025] The first transverse portion 3041 and the mounting groove 3011 of the track beam 301 are nested together. The first transverse portion 3041 is provided with a sensor 303 on one side exposed in the mounting groove 3011. Specifically, the first transverse portion 3041 is exposed on one side of the mounting groove 3011, that is, the middle part of its lower side. The two sides of the lower side are placed in the mounting groove 3011, and the sensor 303 is fixed in the middle part of the lower side.

[0026] The mounting groove 3011 of the track crossbeam 301 is used to connect the I-beam track longitudinal beam 304. The mounting groove 3011 may have steps to ensure reliable installation of the I-beam track longitudinal beam 304. The specific connection method can be achieved by means of fastening bolts, etc., without too many restrictions. Furthermore, the sensing element 303 includes, but is not limited to, a π-shaped steel rail.

[0027] Before connecting the track crossbeam 301 and the I-beam track longitudinal beam 304, the position of the I-beam track longitudinal beam 304 relative to the track crossbeam 301 can be adjusted via a screw structure to match the gap of the outer structure of the suspension frame 1041, ensuring the stability of electromagnetic coupling and current collection; after adjustment, it is locked. Specifically, the screw rotation force of the screw structure can be converted into translational force through auxiliary components to push or pull the I-beam track longitudinal beam 304 to move, achieving the adjustment effect.

[0028] The traction system 2 includes a current receiving device 201 connected to the side of the vertical part 3042. The current receiving device 201 is used to obtain electrical energy from the external power supply system to provide power to the entire vehicle.

[0029] The suspended vehicle 1 includes a suspension frame module 104. An electromagnet module 101 and a vehicle body 106 are respectively connected to both sides of the suspension frame module 104. Specifically, the electromagnet module 101 is located at the top of the suspension frame module 104 and is positioned opposite to the sensing element 303 located at the bottom of the first horizontal part 3041.

[0030] The passenger compartment 106 is located at the bottom of the suspension module 104 and is used to transport passengers. The floor of the passenger compartment 106 is transparent to facilitate viewing. The top of the passenger compartment 106 can be used to install the vehicle's electrical equipment, making the entire vehicle structure compact and reliable. A coupler 105 is provided on the top of the passenger compartment 106 for vehicle coupling and rescue.

[0031] The suspension frame module 104 surrounds the second transverse section 3043. This enclosure allows the suspension frame module 104 to be externally attached to the I-beam track longitudinal beam 304, thereby facilitating the installation, condition inspection, maintenance, and fault rescue of the suspension frame module 104. In case of maintenance, there is no need to return to the depot; the vehicle can be stopped in place, and the suspension frame module 104 can be inspected and maintained in real time.

[0032] The electromagnet module 101 and the sensing element 303 are arranged opposite to each other and cooperate to achieve contactless levitation of the carriage body 106. The traction system 2 includes a current-collecting device 201 and a driving device. The current-collecting device 201 is connected to the vertical part 3042 and is used to obtain electrical energy from the external power supply system. The electromagnet module 101 and the driving device are both electrically connected to the current-collecting device 201. The driving device is located on the side of the second horizontal part 3043 away from the vertical part 3042 and is used to move the carriage body 106. As can be seen from the above, based on the cooperation of the electromagnet module 101 and the sensing element 303, and the arrangement of the driving device, it is possible to achieve vehicle operation without mechanical contact, reduce vibration and noise during movement, and improve ride comfort.

[0033] The suspended maglev vehicle provided in this embodiment serves as a quiet, comfortable, flexible, contactless, low-cost, and space-saving public transportation tool. It effectively improves vehicle operational stability, reduces overall system costs and noise, and enhances vehicle maintenance convenience. Specifically, the flexible route selection refers to its greater adaptability, making it applicable to various usage scenarios.

[0034] Based on any of the above embodiments, please refer to Figure 5 The track system 3 also includes piers 305, with track beams 301 connected to the piers 305. Evacuation passages 306 are provided on both sides of the piers 305, and the evacuation passages 306 are arranged adjacent to the carriage body 106. The height of the evacuation passages 306 is matched with the height of the carriage body 106 for emergency personnel evacuation.

[0035] Specifically, a support 307 is provided on the pier 305, and the track beam 301 is connected to the support 307 for fixation. The support 307 is used to support the track beam 301 and has the functions of transmitting load, buffering vibration, and not restricting the deformation or displacement of the track beam 301. Here, "not restricting the deformation or displacement of the track beam" means that the track beam 301 is allowed to have a certain degree of free deformation or displacement in the longitudinal and / or transverse directions in order to release stress.

[0036] Based on any of the above embodiments, please refer to Figure 2 The track beam 301 is provided with two mounting slots 3011 that are symmetrical with respect to the pier 305. I-shaped track longitudinal beams 304 are suspended in both mounting slots 3011.

[0037] The outer wall of the mounting groove 3011 is connected to a protective member 302, which extends from the edge of the outer wall of the mounting groove 3011 in a direction parallel to the vertical part 3042.

[0038] The protective component 302 is detachably installed on the track beam 301. The protective component 302 protects the internal structure of the track beam 301 from corrosion caused by natural environmental factors such as rain and snow, preventing component failure. Furthermore, the installation height of the protective component 302 is lower than the height of the current-receiving rail 2012, ensuring that there is no mechanical interference with the current-receiving module 1014 or the current-receiving device 2011 when the train passes.

[0039] In actual maintenance, the protective component 302 can be disassembled separately to inspect the relevant parts. If the screw structure needs to be maintained or adjusted, the protective component 302 can be easily removed without damaging the overall structure.

[0040] Based on any of the above embodiments, please refer to Figure 3 The current receiving device 201 includes a current receiving mounting base 2013 connected to the side of the vertical part 3042, a current receiving rail 2012 connected to the current receiving mounting base 2013, and a current receiver 2011 electrically connected to the current receiving rail 2012. The current receiving rail 2012 is used to obtain electrical energy from the external power supply system and provide it to the current receiver 2011.

[0041] A current-collecting rail 2012 is mounted on the current-collecting mounting base 2013, and the current-collecting rail 2012 is connected to the current collector 2011. An external power supply system inputs electrical energy into the current-collecting rail 2012, which forms a stable electrical connection with the current collector 2011 through side current collection. The output interface of the current collector 2011 is connected to the vehicle-mounted power distribution unit. The power distribution unit can distribute electrical energy to different vehicle-mounted power units, such as one path to the electromagnet module 101 to provide power for its excitation; another path to the linear motor 203 to provide power for generating electromagnetic thrust; and it can also supply power to the vehicle's control unit, auxiliary equipment, etc.

[0042] By collecting current from the side, a stable and continuous transmission of electrical energy is ensured, guaranteeing the power supply for all vehicle systems.

[0043] Based on any of the above embodiments, please refer to Figure 1 , Figure 4The driving components include a sensing aluminum plate 202 and a linear motor 203 disposed within the suspension module 104. The sensing aluminum plate 202 is connected to the side of the second horizontal portion 3043 away from the vertical portion 3042. The sensing aluminum plate 202 is connected to the suspension module 104 and is disposed opposite to the linear motor 203. The sensing aluminum plate 202 is used to cooperate with the linear motor 203 to generate a moving thrust. The linear motor 203 is specifically mounted on a motor mounting base 103 disposed inside the suspension module 104. The linear motor 203 may be an actuator motor employing a short stator configuration.

[0044] When the electromagnet module 101 is powered on, it generates a magnetic field, which cooperates with the induction element 303 located on the first transverse part 3041 to generate an electromagnetic attraction that counteracts the weight of the carriage body 106, thereby achieving contactless levitation of the carriage body 106.

[0045] The induction aluminum plate 202 and the linear motor 203 are positioned opposite each other with a certain distance between them to provide traction drive function. Specifically, when the linear motor 203 is energized, it generates a moving magnetic field, which interacts with the eddy currents induced by the induction aluminum plate 202 installed at the bottom of the I-shaped track, generating a horizontal electromagnetic thrust that drives the carriage body 106 to move along the longitudinal direction of the longitudinal beam 304 of the I-shaped track. At the same time, the vertical normal force generated between the linear motor 203 and the induction aluminum plate 202 is opposite in direction to the levitation force of the electromagnet module 101, which is used to counteract force fluctuations during the levitation process and maintain the stability of the levitation gap.

[0046] Based on any of the above embodiments, please refer to Figure 4 The suspended vehicle 1 also includes a guide device 102 connected to the inner side wall of the suspension module 104. The guide device 102 is provided on both sides of the second transverse portion 3043. Each guide device 102 can cooperate with its corresponding second transverse portion 3043 to generate a guiding force so as to control the gap between it and the side of the second transverse portion 3043 to a constant value.

[0047] By setting the gap between the guide device 102 and the side of the second transverse part 3043 to a constant value, it is possible to ensure that the carriage body 106 runs stably along the centerline of the I-shaped track longitudinal beam 304 and maintain the dynamic balance of vehicle operation.

[0048] When the vehicle is driving normally, the gap between the guide device 102 and the side of the second lateral part 3043 is a constant value; if the vehicle is affected by crosswinds, centrifugal force or other unstable conditions and the vehicle body shifts to one side, a corrective force can be generated by the guide device 102 to push or pull the vehicle body back to a stable position.

[0049] In one embodiment, the guiding device 102 is a guiding electromagnet, which has a lateral distance measurement function. This lateral distance refers to the gap between the guiding device 102 and the side of its corresponding second lateral portion 3043. By controlling the left and right lateral gaps of the vehicle to remain consistent, if the measured lateral distance exceeds a set value, the current of the guiding electromagnet is adjusted to ensure that the left and right lateral gaps remain constant. Specifically, in this embodiment, the guiding electromagnet generates a magnetic field after being energized, which interacts with the metal guiding surface of the second lateral portion 3043 to generate a guiding force. This is a master-controlled electromagnetic guidance system with high precision and adaptability.

[0050] In another embodiment, the guide device 102 is a rubber guide wheel, which is a solid rubber tire with high elasticity and wear resistance, capable of withstanding significant lateral impacts. When the vehicle experiences a large lateral deviation, the rubber guide wheel directly abuts against the guide surface of the second lateral portion 3043. The elastic deformation of the rubber tire generates a reaction force, forcibly limiting the vehicle's deviation and preventing derailment. In this embodiment, passive mechanical guidance is achieved through the rubber guide wheel, resulting in a simple and reliable structure.

[0051] Based on any of the above embodiments, please refer to Figure 4 The suspension frame module 104 includes a suspension frame 1041 and an anti-roll module 1042. The suspension frame 1041 and the car body 106 are connected by a plurality of anti-roll modules 1042. The anti-roll module 1042 is divided into a primary module located on a first mounting seat 107 on the left side of the suspension frame 1041 and a secondary module located on a second mounting seat 108 on the right side of the suspension frame 1041. By providing anti-roll modules 1042 on both sides, it can reliably prevent the car body 106 from rolling.

[0052] like Figure 4 The suspension frame module 104 adopts an inverted U-shaped structure. The suspension frame 1041 has an opening 10411 on the side away from the carriage body 106. The second transverse part 3043 is placed in the opening 10411. The two sides of the opening 10411 extend towards the centerline of the suspension frame 1041 to form a connecting part, which is connected to the electromagnet module 101.

[0053] Based on any of the above embodiments, please refer to Figure 4 The electromagnet module 101 includes a suspension module 1012 and a current receiving module 1014. The top of the suspension module 1012 and the sensing element 303 are arranged opposite each other. The side of the suspension module 1012 close to the centerline direction of the suspension frame 1041 is connected to the current receiving module 1014. The current receiving module 1014 is attached to the current receiving device 201.

[0054] The suspension module 1012 is connected to the flow receiving module 1014 on the side of the suspension frame 1041 close to the centerline, so as to effectively utilize the lateral space of the suspension frame 1041 and shorten the force transmission path.

[0055] The current collection module 1014 is installed on the side of the suspension module 1012 and is used to collect current for power supply to the vehicle. Specifically, the current collection module 1014 collects current through the current collector 2011 and the current collection rail 2012, and then transmits the collected electrical energy to the on-board electrical equipment to realize the current power supply for the vehicle. Specifically, the current power supply of the vehicle supplies electrical units such as the electromagnet module 101, the linear motor 203, and the suspension control system to ensure the vehicle's suspension and operation functions.

[0056] Based on any of the above embodiments, please refer to Figure 4 The electromagnet module 101 also includes a measurement module 1013 disposed inside the suspension module 1012. The measurement module 1013 is used to monitor the suspension gap between the sensing element 303 and the suspension module 1012 and the signal is connected to the suspension control system. The suspension control system is used to control the current of the suspension module 1012 according to the monitoring information of the measurement module 1013.

[0057] By placing the side beam module directly inside the suspension module 1012, the suspension gap between the suspension module 1012 and the sensing element 303 can be directly reflected, avoiding measurement errors caused by deformation when installed on an external structure. At the same time, it also avoids the measurement module 1013 being exposed to the external environment and affected by water vapor and impurities, thus improving the integration.

[0058] The measurement module 1013 provides real-time data on the levitation gap, which can be adjusted according to the actual situation to ensure that the levitation module 1012 and the sensing element 303 always maintain a stable gap, so as to achieve reliable contactless levitation.

[0059] Specifically, each of the two sides of the vertical part 3042 is equipped with a measuring module 1013 in the corresponding suspension module 1012. When the suspension gap detected on either side is greater than the preset value, the suspension control system controls the current of the suspension module 1012 to increase the electromagnetic attraction and reduce the gap. When the suspension gap detected on either side is less than the set value, the suspension control system controls the current of the suspension module 1012 to decrease the electromagnetic attraction and increase the gap.

[0060] Specifically, the suspension control system controls the decrease or increase of the current of the suspension module 1012, specifically by controlling the magnitude of the current output from its drive circuit to the suspension module 1012.

[0061] Based on any of the above embodiments, please refer to Figure 4The electromagnet module 101 also includes a main body, a rescue support module 1015, and a parking support module 1017. The rescue support module 1015 and the parking support module 1017 are both connected to the side of the main body near the second horizontal part 3043. The rescue support module 1015 can be moved to approach or move away from the second horizontal part 3043. The installation height of the parking support module 1017 is lower than the installation height of the rescue support module 1015.

[0062] The specific rescue support module 1015 is used for emergency travel in the event of a train levitation failure, and the parking support module 1017 is used for parking the train in the event of a non-levitation failure to prevent it from slipping.

[0063] The rescue support module 1015 is movable to approach or move away from the second transverse part 3043. Specifically, after installation, the rescue support module 1015 is in a state away from the second transverse part 3043 and does not contact it. The electromagnet module 101 and the sensing element 303 cooperate to achieve levitation. If the electromagnet module 101 and the sensing element 303 malfunction or cannot achieve levitation, the rescue support module 1015 is controlled to move to a state that approaches and contacts the second transverse part 3043 so as to enable emergency support for vehicle operation.

[0064] The parking support module 1017 is a non-movable module. When the vehicle is in a non-suspended working condition, such as when it is parked for maintenance, the parking support module 1017 contacts the second transverse part 3043 to stably support the vehicle and prevent it from rolling away.

[0065] In this embodiment, the installation height specifically refers to the height of the rescue support module 1015 and the parking support module 1017 after assembly. By limiting the installation height of the parking support module 1017 to be lower than that of the rescue support module 1015, it is possible to meet the requirements of emergency support operation under suspension failure conditions and stable parking of the vehicle under non-suspension conditions.

[0066] The movable rescue support module 1015 in this embodiment can be achieved by hydraulic drive, but it is not limited to this. Any drive component that can achieve reliable lifting function is acceptable.

[0067] In addition, the main body is also equipped with a suspension module 1016 and a mounting module 1011.
