Description

Technical Field

[0001] This utility model belongs to the field of transportation equipment technology, and specifically relates to a magnetic levitation vehicle. Background Technology

[0002] my country's maglev transportation industry is in a phase of rapid development. Maglev vehicles already in operation or under development in China mainly employ two technical routes: conventional short-stator maglev and conventional long-stator maglev. Conventional long-stator maglev vehicles include high-speed maglevs with speeds reaching 600 km / h, such as the Shanghai Maglev and the high-speed maglev developed by CRRC Qingdao Sifang; and medium-speed maglevs with speeds of 200 km / h, such as the medium-speed maglev developed by CRRC Zhuzhou Locomotive. The existing 200 km / h medium-low speed long-stator maglev suspension technology uses the principle of magnets attracting iron plates. The entire track is made of cast steel plates, bending downwards at both ends to form an inverted "U"-shaped magnetic track structure. The train carriages straddle and encircle the track, with electromagnets installed at the bottom, also bending downwards to below and opposite the "U"-shaped structure of the track, forming a regular "U" structure. The two "U"s facing each other are like two "U"-shaped magnets with opposite magnetic poles facing each other. Because opposite poles attract, the electromagnets at the bottom of the vehicle exert an upward attraction on the track, causing the vehicle to levitate. Suspension and guide windings are installed on the sidewalls of the guide rail. If the vehicle deviates from the center of the guide rail in a plane, the system automatically generates a magnetic field in the suspension windings on each side of the guide rail. This causes the ground magnetic field on the deviating side to attract the superconducting magnetic field of the vehicle body, while the ground magnetic field on the closer side repels the magnetic field of the vehicle body, thus keeping the vehicle from deviating from the center of the guide rail.

[0003] The long stator maglev suspension frame and guide rail used in medium and low speed maglev vehicles have the following problems: the suspension frame contains many parts, and the suspension and guidance functions are integrated into one unit. The guide rail structure is complex and the design is cumbersome. The complex structure has stringent requirements for processing and assembly processes, making production and manufacturing difficult. The large number of parts and the cumbersome structural design result in a large overall weight. The complex structure, difficult manufacturing process and high material consumption make the vehicle manufacturing cost high. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a magnetic levitation vehicle while ensuring the vehicle's operating performance and component strength, thereby solving the problems of complex suspension frame structure, high manufacturing difficulty, large weight, and high manufacturing cost of the existing magnetic levitation vehicles.

[0005] The present invention provides a magnetic levitation vehicle, comprising a plurality of car bodies connected in sequence, each car body being mounted on two first suspension frames and running along a T-shaped guide rail; The first suspension frame includes a crossbeam and four support arms symmetrically arranged on both sides of the crossbeam; Corresponding to the two wing ends of the T-shaped guide rail, a guide electromagnet device is provided on the inner side of the support arm; The lower end of the support arm is connected to a levitation electromagnet, and permanent magnets are provided on the lower sides of the two wings of the T-shaped guide rail. The levitation electromagnet and the permanent magnets are correspondingly matched.

[0006] The suspension frame of the aforementioned maglev vehicle includes a crossbeam and four support arms. The crossbeam and support arms form a semi-enclosed configuration that cooperates with the T-shaped guide rail below. The device for achieving the guiding function is located on the inner side of the support arms, corresponding to the two wing ends of the T-shaped guide rail. The device for achieving the levitation function is located on the lower end of the support arms, corresponding to the permanent magnets on the lower side of the two wings of the T-shaped guide rail. This allows the maglev vehicle to adjust the guiding and levitation functions separately. The structure is simple and reduces the complexity of vehicle control.

[0007] Furthermore, each of the levitation electromagnets is connected to two support arms on the same side.

[0008] Each levitation electromagnet is installed on two support arms on the same side of the suspension frame with a certain distance between them. Compared with the traditional single-point installation method, the double-point installation method improves the stability of the levitation electromagnet during operation.

[0009] Furthermore, the guiding electromagnet device includes a first triangular pull rod, a single pull rod, and a guiding electromagnet. The two ends of the first triangular pull rod are connected to the inner side of the support arm, the third end of the first triangular pull rod is connected to the guiding electromagnet, one end of the single pull rod is connected to the inner side of the support arm, and the other end of the single pull rod is connected to the guiding electromagnet.

[0010] The gap between the guide electromagnet and the T-shaped guide rail is adjusted by the coupling and linkage of the first triangular tie rod and the single tie rod, so that the two are parallel.

[0011] Furthermore, each of the guide electromagnets is connected to two support arms on the same side.

[0012] Similar to levitation electromagnets, each guide electromagnet is installed on two support arms on the same side of the suspension frame with a certain distance between them. Compared with the traditional single-point installation method, the double-point installation method improves the stability of the guide electromagnets during operation.

[0013] Furthermore, a braking device is also provided, and the guiding electromagnet device is replaced with the braking device in a number of the first suspension frames.

[0014] Based on the vehicle's braking requirements and overall layout, a portion of the guide electromagnet devices can be converted into braking devices. This eliminates the need for a separate design for the braking device's installation location and avoids increasing the complexity of the suspension structure.

[0015] Furthermore, the braking device includes a second triangular pull rod, a connecting member, a rubber stack, and a braking electromagnet. One end of the second triangular pull rod is hinged to the inner side of the support arm, and the other two ends of the second triangular pull rod are respectively hinged to one end of the connecting member. The other end of the connecting member is connected to the rubber stack, and the braking electromagnet is mounted on the rubber stack.

[0016] The rubber stack is pre-compressed on the connector and the mounting base of the brake electromagnet, giving the brake electromagnet a lateral preload. During operation and braking, the brake electromagnet acts on the track to generate a suction force. When the suction force is greater than the preload F, the brake electromagnet moves towards the track side and generates braking force through friction with the track. The braking process is simple and effective.

[0017] Furthermore, it also includes a vertical skid device and a rescue support wheel device. Along the length of the vehicle body, the vertical skid device is disposed between the rescue support wheel devices. The vertical skid device and the rescue support wheel device are disposed on both sides of the bottom of the crossbeam and connected to the top of the T-shaped guide rail.

[0018] The vertical skid device and the rescue support wheel device are independent of other components and will not affect the function of other components. At the same time, they play a supporting and emergency rescue role when the train is in an emergency.

[0019] Furthermore, it also includes a second suspension frame, which is disposed between two first suspension frames under the same vehicle body, and the top of the second suspension frame is provided with a movable sliding platform device connected to the vehicle body.

[0020] Adding a second suspension frame under each vehicle body improves the stability of the vehicle body, and a movable sliding platform device is set on the second suspension frame to realize the lateral movement of the suspension frame and the vehicle body.

[0021] Furthermore, the movable slide device includes a linear bearing and a slide. The slide rail of the linear bearing is disposed at the bottom of the vehicle body, and the slider of the linear bearing is fixed to the slide. The slide is disposed at the top of the second suspension frame. The movable slide device cooperates with air springs disposed at both ends of the suspension frame to control the lateral movement of the vehicle body and prevent the vehicle body from tipping over.

[0022] This utility model has the following beneficial effects: 1) The magnetic levitation vehicle provided by this utility model has the guiding, levitation and support rescue devices respectively set on the inner side of the crossbeam support arm, the lower end of the support arm and the two sides of the top of the crossbeam of the suspension frame, so that the magnetic levitation vehicle can adjust the guiding, levitation and support rescue functions respectively, reducing the complexity of vehicle control. 2) The magnetic levitation vehicle provided by this utility model installs a single levitation electromagnet and a single guide electromagnet on two support arms with a certain distance on the same side of the suspension frame. Compared with the traditional single-point installation method, the double-point installation method improves the stability of the levitation electromagnet and the guide electromagnet during operation. 3) The installation positions of the braking device and the guide electromagnet device in the magnetic levitation vehicle provided by this utility model are universal, and there is no need to design the installation position of the braking device separately, which will not increase the complexity of the suspension frame structure. 4) The magnetic levitation vehicle provided by this utility model adds a second suspension frame in the middle of the vehicle body, which improves the support stability of the vehicle body, and sets the movable slide device on the second suspension frame, which enhances the lateral movement control function of the vehicle body.

[0027] like Figure 1 As shown, this utility model provides a magnetic levitation vehicle comprising a plurality of sequentially connected vehicle bodies 200, each vehicle body 200 being mounted on two first suspension frames 300 and running along a T-shaped guide rail 100; as Figure 2-6 As shown, the first suspension frame 300 includes a crossbeam 310 and four support arms 320 symmetrically arranged on both sides of the crossbeam 310.

[0028] like Figure 1-4 As shown, the bottom of the vehicle body 200 is connected to the traction device 210, and the traction device 210 is connected to the top center of the crossbeam 310; air springs 330 are provided on the left and right sides of the top of the crossbeam 310, and the air springs 330 are connected to the bottom of the vehicle body 200.

[0029] like Figure 2 As shown, the cross-section of the crossbeam 310 and the four support arms 320 is semi-enclosed and fits the T-shaped guide rail 100. (See diagram) Figure 2 , Figure 5 As shown, corresponding to the two ends of the T-shaped guide rail 100, a guide electromagnet device 340 is provided on the inner side of the same-side support arm 320 of the first suspension frame 300; the guide electromagnet device 340 includes a first triangular pull rod 341, a single pull rod 342, and a guide electromagnet 343. The two ends of the first triangular pull rod 341 are connected to the inner side of the support arm 320, and the third end of the first triangular pull rod 341 is connected to the guide electromagnet 343. One end of the single pull rod 342 is connected to the inner side of the support arm 320, and the other end of the single pull rod 342 is connected to the guide electromagnet 343. Figure 2-3 As shown, a levitation electromagnet 350 is connected to the lower end of the same-side support arm 320, and permanent magnets 110 are installed on the lower sides of the two wings of the T-shaped guide rail 100. The levitation electromagnet 350 and the permanent magnets 110 are correspondingly matched. Figure 6 As shown, the levitation electromagnet 350 is mounted on two support arms 320 on the same side of the first suspension frame 300 via elastic components 351, such as rubber stacks. Threaded rods are provided at both the top and bottom of the rubber stacks, which are connected and fixed to the levitation electromagnet 350 and the lower end of the support arms 320 respectively via nuts. The elastic component 351 can be adjusted to accommodate the relative movement between the levitation electromagnet 350 and the support arms 320. Thus, a guide electromagnet 343 and a levitation electromagnet 350 are respectively connected and installed on the inner side and lower end of the two support arms 320 on the same side of the first suspension frame 300. The span between the support arms 320 is relatively large, improving the stability of the guide electromagnet 343 and the levitation electromagnet 350 mounted on the first suspension frame 300 during vehicle operation.

[0030] Based on the vehicle's braking requirements and overall layout, select several first suspension frames 300 and adjust and replace a portion of the guide electromagnet devices 340 as follows: Figure 7The braking device 360 ​​shown includes a second triangular pull rod 361, a connecting member 362, a rubber stack 363, and a braking electromagnet 364. One end of the second triangular pull rod 361 is hinged to the inner side of the support arm 320, and the other two ends of the second triangular pull rod 361 are respectively hinged to one end of the connecting member 362. The other end of the connecting member 362 is connected to the rubber stack 363, and the braking electromagnet 364 is mounted on the rubber stack 363. For example, in a four-car train, each car has two first suspension frames 300, for a total of eight first suspension frames. Depending on the vehicle's braking requirements, such as... Figure 10 As shown, the guide electromagnets 343 on the third and sixth first suspension frames are replaced with braking electromagnets 364, while the guide electromagnets 343 remain on the remaining first suspension frames 300.

[0031] like Figure 1 , Figure 3 and Figure 5 As shown, the first suspension frame 300 is also equipped with a vertical skid device 370 and a rescue support wheel device 380. Along the length of the vehicle body, the vertical skid device 370 is positioned between the rescue support wheel devices 380. The vertical skid device 370 and the rescue support wheel device 380 are located on both sides of the bottom of the crossbeam 310 and connected to the top of the T-shaped guide rail 100. The vertical skid device 370 and the rescue support wheel device 380 are independent of other components and will not affect the function of other components. They also serve as support and emergency rescue mechanisms in case of an emergency.

[0032] like Figure 9 As shown, the vehicle body 200 of the magnetic levitation vehicle provided by this utility model can also be mounted on three suspension frames for operation. The three suspension frames are the first suspension frames 300 at both ends and the second suspension frame 400 in the middle. The difference between the first suspension frame 300 and the second suspension frame 400 is that the top of the second suspension frame 400 is provided with a movable sliding platform device 410 connected to the vehicle body 200. Figure 8 As shown, the movable slide device 410 includes a linear bearing 411 and a slide 412. The slide rail 411A of the linear bearing 411 is located at the bottom of the vehicle body 200, and the slider 411B of the linear bearing 411 is fixed to the slide 412. The slide 412 is located at the top of the second suspension frame 400.

[0033] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
