Description

Technical Field

[0001] This utility model relates to the field of EMS, and in particular to a dynamic balancing mechanism for a high-speed EMS test line. Background Technology

[0002] EMS, or conventional magnetic levitation, is a suction levitation system that uses electromagnets on the locomotive and ferromagnetic rails on the guide rails to attract each other and create levitation. When a conventional magnetic levitation train is in operation, the electromagnetic attraction of the levitation and guide electromagnets under the vehicle is first adjusted, and the magnetic reaction with the windings on both sides of the ground track causes the train to float.

[0003] However, when high-speed maglev trains run at high speeds, they generate strong aerodynamic drag, lift, lateral force, and transient impact pressure. These aerodynamic changes affect the train's running stability, increase the difficulty of precise control of the suspension guidance system, and in extreme cases, may even cause a train-track collision accident.

[0004] Therefore, it is necessary to provide a dynamic balancing mechanism for a high-speed EMS test line to solve the above-mentioned technical problems. Utility Model Content

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please refer to the following: Figure 1 and Figure 2 ,in, Figure 1 A schematic diagram of a preferred embodiment of the dynamic balancing mechanism for a high-speed EMS test line provided by this utility model; Figure 2 for Figure 1 The diagram shows an enlarged view of part A. A dynamic balancing mechanism for a high-speed EMS test line includes: a track 1, a suspension assembly 2 disposed on the top of the track 1, the suspension assembly 2 including a body 21, the body 21 being positioned on top of the track 1;

[0024] The connecting component 3 includes a connecting plate 32, which is embedded at both ends of the track 1;

[0025] The balancing assembly 4 includes a transmission rod 41, one end of which is connected to the surface of the connecting plate 32.

[0026] The track 1 can be made of stainless steel, aluminum alloy, or carbon fiber reinforced composite materials, preferably carbon fiber reinforced composite materials, which have high tensile strength (up to 700 MPa) and are lightweight, reducing weight by more than 30% compared to traditional metal materials. It also has good wear resistance. The suspension component 2 moves the track by electromagnetic force. The bottom of the vehicle body 21 engages with the top of the track 1. The connecting component 3 connects the transmission. The track 1 has grooves on the left and right sides near the top. There are two connecting plates 32, which are slidably embedded in the grooves. One end is movably embedded on the outer surface of the two ends of the track 1. The balancing component 4 maintains the dynamic balance of the vehicle body 21 through the transmission.

[0027] The bottom of the top of the track 1 and the inner surface of the bottom of the vehicle body 21 are equipped with vertically suspended magnetic blocks 22, and the inner surfaces of the left and right ends of the top of the track 1 and the left and right ends of the vehicle body 21 are equipped with guide magnetic blocks 23.

[0028] The two vertically suspended magnetic blocks 22 at the bottom of the vehicle body 21 and the two vertically suspended magnetic blocks 22 on the track 1 generate an attraction force, thereby lifting the vehicle body 21 into a suspended state. Then, the attraction force generated by the two guide magnetic blocks 23 at the bottom of the vehicle body 21 and the two guide magnetic blocks 23 at the top of the track 1 maintains balance and guides movement.

[0029] The inner surfaces at both ends of the bottom of the vehicle body 21 are connected to slots 31, and one end of the connecting plate 32 is connected to the surface of the slots 31.

[0030] There are two slots 31, which are respectively opened on the inner surface of the bottom ends of the track 1, and the two connecting plates 32 are respectively slidably embedded in the two slots 31 and engaged.

[0031] The transmission rod 41 is installed inside the track 1, and the other end of the transmission rod 41 is connected to a sliding block 42. A limit rod 43 is fixedly connected inside the track 1, and the sliding block 42 is connected to the surface of the limit rod 43.

[0032] The transmission rods 41 are arranged in pairs, with multiple sets in total. In each set, one end of each pair of transmission rods 41 is rotatably connected to the surface of the two connecting plates 32. A groove is opened inside the track 1, and the sliding block 42 is slidably embedded inside the groove.

[0033] The track 1 is fixedly connected to a limiting rod 43, and the sliding block 42 is connected to the surface of the limiting rod 43.

[0034] The other ends of the two transmission rods 41 in each group are rotatably connected to the two ends of the sliding block 42, and the limiting rod 43 is fixedly connected inside the groove, and the sliding block 42 is slidably sleeved inside the groove.

[0035] A reset spring 44 is mounted on the surface of the limiting rod 43, and one end of the reset spring 44 is connected to the upper and lower surfaces of the sliding block 42.

[0036] Each limit rod 43 is fitted with two return springs 44, one end of which is fixedly connected to the upper and lower ends of the sliding block 42, respectively, so as to give the sliding block 42 an upward and downward force of the same magnitude, thereby keeping the sliding block 42 stationary.

[0037] The working principle of the dynamic balancing mechanism for a high-speed EMS test cable provided by this utility model is as follows:

[0038] During operation, the inner surface of the bottom of the vehicle body 21 attracts the upper and lower suspended magnetic blocks 22 at the top and bottom of the track 1, lifting the vehicle body 21. The guide magnetic blocks 23 at both ends of the top of the track 1 attract the guide magnetic blocks 23 at both ends of the bottom of the vehicle body 21, keeping the vehicle body 21 stable and guiding it. When the stator on the track 1 and the rotor on the motor at the bottom of the vehicle body 21 are energized, electromagnetic induction propels the vehicle body 21 forward. When the vehicle body 21 is tilted by the external environment, the tilted end pushes the connecting plate 32 connected to it, thereby causing the connecting plate 32 to drive one end of the transmission rod 41 to move inward into the track 1. Limited by the connection between the sliding block 42 and the limiting rod 43, the angle of the transmission rod 41 changes, and the other end pushes the sliding block 42 to slide downward. At the same time, the angle of the transmission rod 41 connected to the sliding block 42 changes, giving the connecting plate 32 an inward pulling force. Thus, the connecting plate 32 pulls the other end of the vehicle body 21 inward to reset through the connection with the slot 31, achieving dynamic balance.

[0039] Compared with related technologies, the dynamic balancing mechanism for a high-speed EMS test line provided by this utility model has the following advantages:

[0040] This utility model provides a dynamic balancing mechanism for a high-speed EMS test line. Through the connection of the connecting component 3 and the balancing component 4, when the vehicle body 21 shakes, the force transmitted by the balancing component 4 pushes the other end of the vehicle body 21 in the opposite direction, thereby pushing the vehicle body 21 to reset, maintaining the dynamic balance of the vehicle body 21, and improving the running stability of the train.
