Description

Technical Field

[0001] This utility model relates to the field of levitation train technology, and in particular to an embedded maglev transportation bogie, maglev train and maglev system. Background Technology

[0002] Electromagnetic guidance technology has advantages such as being contactless, frictionless, and low-power, and can provide a high-speed, stable, and precise operating environment and conditions. Its applications in high-precision fields are constantly expanding, especially in aerospace, transportation, precision manufacturing, and basic scientific experiments. Specific applications include high-speed maglev trains, magnetic bearings, magnetic levitation machine tools, and accelerator colliders.

[0003] Currently, the undercarriage of maglev trains generally uses bogies set on the upper or outer side of the track, which is not very safe and the risk of maglev trains derailing is relatively high. In addition, in existing medium and low speed maglev trains, after the train is levitated, the air gap of the linear motor increases, which reduces the efficiency of the motor and increases energy consumption. Utility Model Content

[0004] This invention provides an embedded maglev transportation bogie, maglev train, and maglev system to solve the technical problems of low safety in existing maglev trains.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows: On the one hand, this utility model provides an embedded magnetic levitation transportation bogie, including multiple support wheels, a frame, a guide transmission assembly, two suspension mechanisms, two linear drive mechanisms, a connecting base, a suspension controller, and a traction controller; Multiple support wheels are mounted on the upper side of the frame via a guide transmission assembly. All support wheels are located on the external track. Two suspension mechanisms are respectively mounted on the left and right sides of the frame, and two linear drive mechanisms are respectively mounted on the two suspension mechanisms. A connecting base is rotatably connected to the upper side of the frame, and the frame is connected to the external maglev car body via the connecting base. The suspension controller and traction controller are both mounted on the periphery of the frame. The suspension controller is used to control the two suspension mechanisms, and the traction controller is used to control the two linear drive mechanisms.

[0007] Alternatively, the guiding transmission assembly is a chain assembly, which includes two first rotating shafts, two sprockets, two first supports, and a chain. Two support wheels are respectively mounted on the frame via the two first supports, and the support wheels and the first supports are rotatably connected. The two first supports are respectively rotatably connected to the frame via the two first rotating shafts, and the first rotating shafts are perpendicular to the frame. The two sprockets are respectively mounted on the two first rotating shafts, and the chain is mounted on the two sprockets. Alternatively, the guiding transmission assembly is a gear assembly, which includes two second rotating shafts, one third rotating shaft, two second supports, a driving wheel, a transmission wheel, and a driven wheel. The two support wheels are respectively mounted on the frame via the two second supports, and the support wheels and the second supports are rotatably connected. The two second supports are respectively rotatably connected to the frame via the two second rotating shafts. The third rotating shaft is located between the two second rotating shafts and rotatably connected to the frame. Both the second and third rotating shafts are perpendicular to the frame. The driving wheel and the driven wheel are respectively mounted on the two second rotating shafts, and the transmission wheel is mounted on the third rotating shaft. Both the driving wheel and the driven wheel mesh with the transmission wheel.

[0008] Furthermore, the levitation mechanism includes a support arm and a levitation electromagnet; the levitation electromagnet is mounted on the frame via the support arm and is positioned directly below the external inverted U-shaped rail. During normal operation of the maglev train, the levitation electromagnet suspends the train above the track; when the train disembarks, the support wheels return to the track.

[0009] Furthermore, the levitation mechanism also includes a gap sensor; the gap sensor is installed on the upper side of the levitation electromagnet and is used to collect the air gap between the levitation electromagnet and the inner wall of the external inverted U-shaped rail in real time; the gap sensor is electrically connected to the levitation controller.

[0010] Furthermore, the linear drive mechanism includes a motor support frame and a linear induction motor; The linear induction motor is mounted on the suspension mechanism via a motor support frame, and is located next to the external linear motor induction plate; the linear motor induction plate is made of aluminum or copper.

[0011] In another aspect, this utility model also provides a maglev train, comprising multiple maglev carriages connected end to end, each maglev carriage including a maglev car body and two or more maglev traffic bogies, the maglev car body being mounted on two or more maglev traffic bogies.

[0012] In another aspect, this utility model also provides a maglev system, including the maglev train and track described above, wherein the maglev train is installed on the track.

[0013] Furthermore, the track includes a base plate, two side plates, two drop-off running plates, two linear motor induction plates, and two inverted U-shaped rails; Two side plates are vertically and symmetrically arranged on the left and right sides of the upper part of the base plate.

[0014] Furthermore, the track also includes multiple supporting stiffeners, which are divided into two groups and symmetrically arranged on the upper side of the base plate. The supporting stiffeners are fixedly connected to the unloading running plate and the side plate.

[0015] Furthermore, the base plate, side plates, unloading running plate, inverted U-shaped rail, and supporting stiffeners are all made of steel.

[0016] The beneficial effects of this utility model are: 1. Compared to traditional maglev trains where the undercarriage is typically mounted on the upper or outer side of the track via bogies, this invention uses an embedded design to install the maglev train bogies within the track. Furthermore, the track of this invention is entirely made of steel, with the suspension mechanism embedded on the upper side of the track and the linear drive mechanism embedded on the left and right sides. This design fully utilizes all four sides of the track, resulting in a more stable, safe, and reliable structure. Compared to traditional maglev trains, the maglev train of this invention has a lower risk of derailment during high-speed travel.

[0017] 2. In existing medium- and low-speed maglev trains, the air gap of the linear induction motor increases after the maglev train levitates, which reduces the efficiency of the linear induction motor and increases energy consumption. This invention places the linear induction motor on both sides of the track, so the levitation of the maglev train does not affect the air gap of the linear induction motor.

[0030] During operation, this utility model controls the air gap between the suspension electromagnets 42 on both sides of the frame 2 and the inner wall of the track 7 through the suspension controller, so that the frame 2 can always maintain a corresponding air gap with the inner wall of the track 7 during the forward and backward movement. During operation, if the air gap of one side of the suspension electromagnet 42 becomes smaller, the suspension electromagnet 42 on the other side will exert force to pull it back until the air gaps on both sides are balanced, thereby realizing the guiding function.
