Description of the invention () (Please read the precautions on the back before 埴. Page 4) This invention is related to the magnetic levitation system, especially a vehicle's magnetic levitation system, which has high magnetic levitation efficiency and automatic guidance. According to the function, the magnetic levitation system 1 of the conventional vehicle is shown in the first figure, and includes a permanent magnet 2 and two electromagnets 3 respectively located at the two and five ends of the permanent magnet 2 to form the magnetic levitation system 1 as a whole. U-shaped, in which the electromagnet 3 is composed of a rod-shaped core 4 and a coil 5. When the coil 5 is not energized, the magnetic flux of the magnetic levitation system 1 is equivalent to the magnetic flux of the permanent magnet 2. When the coil 5 is energized, At this time, the magnetic flux of the magnetic levitation system 1 will increase or decrease. In this way, the user can change the magnetic flux of the magnetic levitation system 101 by adjusting the current of the coil 5; the magnetic levitation system 1 can be set on a carrier (not shown) The top and below a track 6, the attraction of the magnetic levitation system 1 to the track 6 and the weight of the vehicle are balanced, so that the vehicle can be suspended below the track when it is moving or stationary, and the Maglev system 1 and the track There will be a gap between the channels 6 to achieve the so-called "maglev" function. 15 However, the above structure has at least the following shortcomings: 1 Large magnetic leakage, which makes the unit of permanent magnet weight less attractive, that is, The magnetic efficiency is poor, and more permanent magnets are needed to generate the required magnetic force, so the manufacturing cost is greatly increased; printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 2 · Because the width of the track 6 is larger than the entire magnetic levitation system 1 Width of 20, so the magnetic levitation system 6 is prone to instability of lateral displacement, and cannot be 'positive' automatically; 3 · Because the permanent magnet 2 is located at the bottom of the magnetic levitation system 1, it is connected to the magnetic levitation system 1 When on the carrier, the permanent magnet 2 must not be in contact with the magnetically permeable substance, otherwise it will cause magnetic leakage and cause the magnetic levitation system 6 to be lost. -3- This paper size applies to China National Standard (CNS) A4 (210X 297) (Centre) 558530 A7 B7 V. The description of the invention (), the trouble during assembly is increased. (Please read the precautions on the back and then the ¥ page.) In view of the above defects, the main purpose of the present invention is to A magnetic levitation system for a vehicle is provided, whose magnetic levitation efficiency is 1¾ and the manufacturing cost is low. Another object of the present invention is to provide a magnetic levitation system for a vehicle, which has an automatic guiding function without causing a yaw. The present invention Yet another object is to provide a magnetic levitation system for a vehicle, which is convenient and simple to assemble. In order to achieve the purpose of the previous disclosure, the magnetic levitation system of the vehicle provided by the present invention is provided on a vehicle for magnetic permeability. The orbit creates an attractive force, so that the 10 carrier can bear weight and float in the relative position of the track. The magnetic levitation system includes an electromagnet and two permanent magnets. The electromagnet is arranged on the carrier and has a U-shape as a whole. With two tooth poles, the two permanent magnets are respectively stuck to the two tooth poles and are located below the track, and the width of the track is slightly smaller than the width of the electromagnet, whereby the magnetic levitation system has high magnetic levitation efficiency and 15 Those with automatic correction function. In order to better understand the features of the present invention, the following preferred embodiment will be described with reference to the drawings, wherein: The second diagram is a schematic diagram of the setup of a preferred embodiment of the present invention. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. The third figure is a perspective view of a preferred embodiment of the present invention. 20 The fourth diagram is a schematic diagram of a preferred embodiment of the present invention. Please refer to the second to fourth figures. The magnetic levitation system 10 of the vehicle provided by a preferred embodiment of the present invention is set on the top of a vehicle 12, and the number of the magnetic levitation system 10 is four, which are two or two pairs respectively. It is set under the second track 14 and the attraction between the magnetic levitation system 10 and the magnetically permeable track 14 makes the carrier -4- The paper size applies to the Chinese National Standard (CNS) A4 specification (210X 297 mm) 558530 A7 B7 V. Description of the invention () (Please read the precautions on the back before eating: this page) 12 Can bear weight and float in the relative position of the track 14, where the magnetic levitation system 10 includes an electromagnet 20 and two permanent magnets 30. The electromagnet 20 is disposed on the carrier 12 and includes a U-shaped iron core 22, and two coils 24 are not wound around the iron core 22, so that two free ends of the electromagnetic 5 iron 20 form two tooth poles 26 Among them, in order to reduce the eddy current generated in the iron core 22, the iron core 22 may be formed by stacking a plurality of U-shaped silicon steel sheets 23. In addition, the width of the electromagnet 20 is slightly larger than the width of the track 14. The two permanent magnets 30 are in a sheet shape, and are respectively adhered to the two tooth poles 26 10 and located below the track 14, and a gap is left between the two and the track 14. # 1 Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. When the coil 24 is not energized, the magnetic flux of the magnetic levitation system 10 is provided by the two permanent magnets 30. When the same current is applied to the coil 24, it is as As shown in the four figures, the magnetic flux of the magnetic levitation system 10 will increase due to the addition of the magnetic flux of the electromagnet 20 in the same direction, and the suction force with the track 14 will also increase by 15, thereby adjusting the current of the coil 24 of the electromagnet 20 Can control the attraction between the magnetic levitation system 10 and the track 14, and then control the size of the gap between the two. In more detail, the attraction between the magnetic levitation system 10 and the track 14 communicates with the coil 24. The square of the current is directly proportional to the square of the gap between each other. 20 Moreover, the size of the gap between the magnetic levitation system 10 and the track 14 can be controlled by a feedback control device, and the feedback control device can automatically detect the size of the gap between the two and send out a control signal for the current of the coil 24, Adjust the magnetic flux of the magnetic levitation system 10 and the size of the gap between the magnetic levitation system 10 and the track 14. When the gap is too large, the feedback control device sends a signal -5- This paper size applies to China National Standard (CNS) A4 specifications (210X297 mm) 558530 A7 B7 V. Description of the invention () (Please read the precautions on the back before ^^ this page) Increase the magnetic flux of the magnetic levitation system 10 to increase the attraction between the magnetic levitation system 10 and the track 14. Large, the gap will decrease at the same time, on the contrary, when the gap is too small, the feedback control device can send a signal to reduce the magnetic flux of the magnetic levitation system 10, so that the attraction between the magnetic levitation system 10 and the track 14 is reduced, 5 At the same time, the gap will increase, so that it is constantly adjusted. When a proper gap is finally reached, only the magnetic force of the two permanent magnets 30 can carry the weight of the carrier 12. At this time, the magnetic levitation And a balance system 10 to a suspension of nearly zero power consumption, wherein the feedback control means control the Department is well known in the industry, this tolerance is not repeated here. 10 Since the two permanent magnets 30 are stuck to the U-shaped electromagnet 20 bis printed on the tooth pole 26 of the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, the magnetic leakage phenomenon of this structure will be greatly reduced compared to the conventional structure, making the unit The attractive force generated by the weight of the permanent magnet increases, effectively improving the magnetic efficiency, and greatly reducing the manufacturing cost; further, because the magnetic levitation system .10 is slightly smaller than the track 14 and the magnetic lines of force are more stable when they have the shortest path15 Due to the fixed characteristics, this structure can provide the function of automatic guidance, so that the magnetic levitation system 10 and the vehicle 12 can be suspended below the track 14 without being deflected when moving or stationary; moreover, because the two permanent The magnet 30 is disposed on the top of the electromagnet 20, so when the electromagnet 20 is connected to the carrier 12, whether the material of the carrier 12 is magnetically conductive or not, it will not cause 20 magnetic leakage. Extremely simple and effective to improve the lack of knowledge structure, so as to achieve the purpose of cost invention. It is also worth mentioning that the vehicle can be equipped with a predetermined number of magnetic levitation systems as required, and even with different numbers of tracks, only the purpose of magnetic levitation can be achieved, and it is not necessary to use a four magnetic levitation system as described in the above embodiments.
