Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of permanent magnet electric suspension, in particular to a suspension frame and an electric suspension rail vehicle. BACKGROUND

[0002] The existing magnetic suspension technology is mainly based on four basic principles for research. One is permanent magnet suspension, the basic principle of which is to rely on the repulsion of like poles to achieve suspension. Two is the common magnetic suspension, which follows the principle of minimum magnetic resistance, that is, the magnetic resistance in the ferromagnetic material is much smaller than that in the air, so the magnetic field excited by the electromagnet will produce a force to pull the ferromagnetic material close to the magnetic source after passing through the ferromagnetic material, called electromagnetic attraction, thereby overcoming the gravity of the vehicle body to achieve suspension. Three is pinning suspension, in which the superconducting material enters the superconducting state in the magnetic field and is fixed at a specific position in space. The superconductor installed on the vehicle body is fixed in space by the track magnetic field to achieve suspension. Four is electric suspension, which is based on Lenz's law. The vehicle-mounted permanent magnet generates a time-varying source magnetic field through rotation, translation and other methods, thereby inducing eddy currents inside the closed conductor track, and then forming a "mirror image magnetic field" to interact with the source magnetic field to generate electromagnetic force.

[0003] The permanent magnet electric suspension system can be divided into discrete coil type tracks (ladder-shaped short circuit, window-shaped short circuit, "8" shaped zero flux coil, etc.) and continuous conductor plate type tracks (stainless steel, aluminum plate, copper plate, etc.) according to the track form. The current suspension system is an "8" shaped coil type permanent magnet electric suspension, which is a new type of permanent magnet electric suspension system with the advantages of simple structure and small magnetic resistance.

[0057] The core of the present application is to provide a suspension frame, which is suitable for a permanent magnet electric suspension system, so as to help realize the engineering application of a coil type permanent magnet electric suspension system.

[0058] Another purpose of the present application is to provide an electric track suspension vehicle.

[0059] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0060] As shown in the drawings, Figure 1 The present application discloses a suspension frame for a permanent magnet electric suspension system, which comprises a suspension frame structure 100, a cross beam 200, a permanent magnet 300, a support wheel module 500 and a guide wheel module 600.

[0061] It should be noted that in the drawings, the x direction represents the advancing direction along the track, hereinafter referred to as the longitudinal direction, the y direction represents the horizontal direction to the ground and perpendicular to the longitudinal direction, hereinafter referred to as the transverse direction, and the z direction represents the vertical direction to the ground and perpendicular to the longitudinal direction, hereinafter referred to as the vertical direction. The suspension frame disclosed in the embodiments of the present application is suitable for an "8" type coil permanent magnet electric suspension system, wherein the "8" type coil refers to a copper coil with two loops, like an "8" character. The "8" type coil permanent magnet electric suspension refers to that "8" type coils and motor driving coils are installed on the two side walls of the "U" type track. The suspension frame disclosed in the embodiments of the present application is suitable for a coil type permanent magnet electric suspension system of a "U" type track, wherein the "U" type track refers to a cross section like a letter "U", and the two sides of the ground track are vertical track beams.

[0062] The suspension frame 100 provides a mounting base for the installation of a measurement and control system, the cross beam 200 is connected with the suspension frame 100, and forms a support platform of the measurement and control system. The permanent magnet 300 is arranged on both sides of the suspension frame 100 and is fixedly connected with the cross beam 200. It should be noted that the permanent magnet 300 refers to a Halbach permanent magnet array structure. The permanent magnet 300 interacts with the coil arranged on the track vertical beam to generate electromagnetic force, thereby providing suspension force and guiding force for the vehicle operation. In an embodiment of the present application, the permanent magnet 300 includes four pieces, two pieces are arranged on each side of the suspension frame 100. It should be noted that the specific number of the permanent magnet 300 can be set according to actual conditions.

[0063] The support wheel module 500 is arranged at the bottom of the suspension frame 100 and supports the suspension frame when the suspension frame is not floated. When the vehicle is not floated, the suspension frame relies on the support wheel module 500 to bear the entire weight, and at the same time, the vehicle accelerates along the track forward direction under the action of the traction coil on both sides of the track. After entering the suspension stage, the support wheel module 500 is separated from the ground and loses the supporting effect, and only ensures the safety problem caused by the suspension failure.

[0064] The guide wheel module 600 is fixedly connected to the cross beam 200 and supports the bearing surface of the vertical beam at both ends of the track. When the vehicle is not floated, the guide wheel module 600 can limit the lateral movement of the suspension frame and limit the travel direction of the suspension frame, especially when passing through a curve, to ensure that the suspension frame does not roll laterally and ensure the safety during operation to avoid a derailment accident. When the vehicle is floated, the guide wheel module 600 plays an auxiliary safety role.

[0065] The suspension frame disclosed in the embodiment of the present application starts the power supply, the permanent magnet 300 interacts with the coil arranged on the track beam, and the suspension frame moves along the track under the action of the driving coil. The suspension frame 100 supports the vehicle body and supports the permanent magnet 300 when the vehicle body is not in operation. The cross beam 200 is connected with the suspension frame 100 to form a support platform of the measurement and control system, and the cross beam 200 can prevent the suspension frame 100 from being deformed into a quadrilateral shape. The support wheel module 500 provides support for the vehicle body in the non-suspension stage and relieves the impact. The guide wheel module 600 is supported laterally on the bearing surface of the vertical beam at both ends of the "U"-shaped track, so that the whole suspension frame remains horizontal, avoids rolling laterally, and ensures safe operation without derailing during the travel of the vehicle body. When entering the suspension area, the permanent magnet 300 interacts with the "8"-shaped coil on both sides of the track to lift the suspension frame 100, and the support wheel module 500 plays an auxiliary safety role. The suspension frame provided by the present application fills the gap in the design of the permanent magnet electric suspension system suspension frame, and helps to realize the exploration and research of the practical application of the new permanent magnet electric suspension.

[0066] As Figure 2As shown in the figure, the suspension frame disclosed in the embodiment of the present invention has a suspension frame structure 100 that is overall in a "mu" - shaped structure. Both ends of the suspension frame structure 100 are connected to the cross - beam 200. In order to leave enough space for installing the measurement and control system, the connection part between the suspension frame structure 100 and the cross - beam 200 is a concave - down structure, and the cross - beam 200 constitutes the support platform of the measurement and control system. Specifically, the suspension frame structure 100 and the cross - beam 200 can be connected by bolts. Corresponding mounting holes are respectively provided on the suspension frame structure 10 and the cross - beam 200, or they can be connected in other forms.

[0067] As Figure 7 shown in the figure, the cross - beam 200 of the suspension frame disclosed in the embodiment of the present invention is in an "H" - shaped structure, and a connecting beam 210 is provided on the cross - beam 200. Since the permanent magnet 300 will be subjected to a large lateral force and the longitudinal length of the permanent magnet 300 is relatively long, in order to prevent the phenomenon of buckling of the compression bar at both ends of the cross - beam 200, the cross - beam 200 adopts an "H" - shaped structure. At the same time, a connecting beam 210 is provided on the cross - beam 200. Specifically, the connecting beam 210 is arranged in the middle position of the cross - beam 200 to prevent the suspension frame structure 100 from undergoing a quadrilateral deformation due to uneven or asynchronous electromagnetic forces received by the permanent magnet 300. In order to better fixedly connect the cross - beam 200 with the permanent magnet 300, support surfaces for fixedly connecting with the permanent magnet 300 are provided at both ends of the cross - beam 200. Surface contact can ensure the firmness and stability of the connection between the cross - beam and the permanent magnet 300. Since the permanent magnet 300 has a large mass itself and is installed at both ends of the cross - beam 200, the cross - beam 200 straddles on the suspension frame structure 100 to form a cantilever beam, so it is very easy to cause bending deformation of the cross - beam 200. The structure of the cross - beam 200 is designed in a fish - belly form, which has good bending resistance. Specifically, there are two cross - beams 200, which are respectively arranged at both ends of the suspension frame structure 100.

[0068] As Figure 1 and Figure 8 shown in the figure, in order to play a role in laterally adjusting the gap between the permanent magnet 300 and the track and alleviating impact vibration, in a specific embodiment of the present invention, a magnet back - plate rubber pad 700 is provided between the support surface of the cross - beam 200 and the back - plate of the permanent magnet 300. Specifically, the specific number of the magnet back - plate rubber pads 700 is set according to the actual situation. By adjusting the number of the magnet back - plate rubber pads 700, the lateral working gap can be slightly adjusted, that is, the distance between the working surface of the permanent magnet 300 and the surface of the "8" - shaped coil can be adjusted. In a specific embodiment, the support surface of the cross - beam 200 and the permanent magnet 300 are fixedly connected by bolts. In order to ensure the firmness of the connection, mounting holes for cooperating with the bolts are provided around the magnet back - plate rubber pad 700. Multiple experimental conditions can be adjusted according to the specific line experiment situation.

[0069] As Figure 7As shown, in order to position the cross beam 200 horizontally, in an embodiment of the present application, a stopper 220 is arranged on the cross beam 200, specifically, the stopper 220 is arranged on both ends of the cross beam 200 and contacts the suspension frame 100 on both sides, the stopper 220 contacts the side of the suspension frame 100 to position the cross beam 200 horizontally.

[0070] As shown in FIG. 1, the suspension frame 100 is arranged on the ground track 200, and the cross beam 200 is arranged on the suspension frame 100. Figure 10 and Figure 11 As shown in FIG. 1, the suspension frame 100 is arranged on the ground track 200, and the cross beam 200 is arranged on the suspension frame 100.

[0071] The other end of the support wheel adjusting arm 530 is rotationally connected with the suspension frame 100. In order to make the support wheel 510 telescopic, the support wheel adjusting arm 530 is a telescopic structure and can be elongated or shortened along the axial direction. Specifically, the support wheel adjusting arm 530 has a double pull screw mechanism, that is, the two ends of the screw have two threads with opposite rotation directions, so that the adjusting arms connected with the two ends of the screw can be simultaneously close or away from each other to adjust the length of the support wheel adjusting arm 530. The arrangement of the support wheel adjusting arm 530 can adjust the position of the support wheel 510 in the vertical direction, thereby adjusting the height of the suspension frame 100, realizing the requirement that the offset amount between the center line of the permanent magnet 300 and the center line of the "8" shaped coil is adjustable, and at the same time, the influence of the ground track on the suspension frame can be relieved. In order to alleviate and shock vibration, the first rubber pad 540 is fixed on the support wheel adjusting arm 530, and the rubber pad has high elasticity and high viscosity, which is a good damping device.

[0072] As shown in FIG. 1, the suspension frame 100 is arranged on the ground track 200, and the cross beam 200 is arranged on the suspension frame 100. Figure 9 As shown in FIG. 1, the suspension frame 100 is arranged on the ground track 200, and the cross beam 200 is arranged on the suspension frame 100.

[0073] As shown in FIG. 1, the suspension frame 100 is arranged on the ground track 200, and the cross beam 200 is arranged on the suspension frame 100. Figure 1As shown in the drawings, in a specific embodiment of the present application, the guide wheel module 600 is a double guide wheel structure, including a guide wheel 610 and a guide wheel support 620. Specifically, the guide wheel 610 is arranged in two layers, and is arranged on the upper and lower sides of the suspension frame 100. The two guide wheels 610 are arranged on the guide wheel support, and the guide wheel 610 is rotatably connected to the guide wheel support. One of the guide wheel supports is fixedly connected to the cross beam 200. Specifically, the guide wheel support can be connected to the cross beam 200 by bolts, and threaded holes are formed in the guide wheel support and the cross beam 200. The two guide wheel supports are connected by the guide wheel support 620, and the two guide wheels 610 respectively extend out of the permanent magnet 300. The guide wheel 610 is supported on the support surface of the vertical beam at the two ends of the U-shaped track, and is supported at two points. The double guide wheel structure makes the contact between the guide wheel 610 and the track a surface contact, which ensures that the suspension frame can limit its rolling degree of freedom when subjected to divergent guide force, especially when the vehicle passes through a curve. The guide wheel 610 is supported on the support surface of the vertical beam at the two ends of the U-shaped track, which ensures safety during operation.

[0074] As shown in the drawings, Figure 12 and Figures 4-6 In order to make the connection between the suspension frame 100 and the cross beam 200 more secure during the suspension stage of the vehicle body, in a specific embodiment of the present application, a cross beam pressing plate 400 is arranged on the cross beam 200, and the cross beam pressing plate 400 is fixedly connected to the suspension frame 100. Due to the characteristics of the electric suspension principle itself, the maglev train designed according to the principle cannot achieve a static floating state. Therefore, when not floating, the weight of the vehicle body is transmitted from the suspension frame 100 to the support wheel module 500, and after floating, the weight of the vehicle body is transmitted from the suspension frame 100 to the cross beam 200. Therefore, the cross beam pressing plate 400 is designed as a fastener for the cross beam 200 and the suspension frame 100. Specifically, the cross beam pressing plate 400 is arranged along the length direction of the suspension frame 100 (i.e. along the advancing direction of the track), and the cross beam pressing plate 400 is arranged above the cross beam 200 and is fixedly connected to the suspension frame 100 by a fixing member.

[0075] As shown in the drawings, Figure 5 In order to transmit traction and braking forces, and at the same time to alleviate a part of the impact and vibration generated during operation, in a specific embodiment of the present application, a second rubber pad 800 is arranged between the suspension frame 100 and the cross beam 200. The arrangement of the second rubber pad 800 can alleviate a part of the impact and vibration during operation. The specific number of the second rubber pad 800 can be adjusted according to actual conditions. By changing the number of the second rubber pad 800, the centerline deviation distance can be adjusted, i.e. the deviation distance between the longitudinal centerline of the permanent magnet 300 and the longitudinal centerline of the "8" shaped coil. In order to better position the cross beam 200, a rubber pad seat 900 is arranged between the second rubber pad 800 and the cross beam 200.

[0076] As shown in Figure 1 the above embodiment, the rubber pad 900 has two wings protruding upward to fix the cross beam 200, achieving better positioning effect on the cross beam 200. In order to make the rubber pad 900 better cooperate with the second rubber pad 800, the cross section of the two ends of the rubber pad 900 is correspondingly arranged with the cross section of the two ends of the second rubber pad 800, and the arrangement of the rubber pad 900 can play a role of shock absorption and buffering.

[0077] As shown in Figure 3 and Figure 3 in order to achieve the longitudinal and vertical positioning effect of the suspension frame 100 on the cross beam 200, in a specific embodiment of the present application, the third rubber pad 1000 is arranged between the cross beam pressing plate 400 and the suspension frame 100.

[0078] As shown in Figure 6 in a specific embodiment, the third rubber pad 1000 is a trapezoidal rubber pad, that is, its cross section is isosceles trapezoidal, which can cooperate with the inclined surface of the concave area of the suspension frame 100 and the rubber pad 900 mounted on the cross beam 200 to form a "V" type space in which the second rubber pad 800 can be placed. As shown in ​ the second rubber pad 800, the rubber pad 900 and the third rubber pad 1000 jointly constitute the connecting part of the suspension frame 100 and the cross beam 200, which can not only achieve the longitudinal and vertical positioning effect of the suspension frame 100 on the cross beam 200, but also can reduce the impact and vibration generated during operation, effectively improve the vibration of the suspension itself after being disturbed by the outside world, and improve the stability of the whole system. In order to ensure that the bolt for fixing the cross beam pressing plate 400 can pass through the third rubber pad 1000 and be positioned, a through hole is formed in the third rubber pad 1000.

[0079] The embodiment of the present application also discloses an electric suspension rail vehicle, which comprises the suspension frame disclosed in the above embodiment, and therefore has all the technical effects of the above suspension frame, which will not be described here.
