Embodiment 1

[0042] Such as figure 1 , figure 2 and image 3 As shown, a magnetic levitation vehicle includes a vehicle body 1 and a track. A linear motor power source and two magnetic levitation devices are arranged between the vehicle body and the roadbed. The magnetic levitation device is a reluctance magnetic force levitation device 3 . The yoke I7 and the yoke frame 6 of the reluctance type magnetic levitation device form a track, and the magnet and the magnet frame 10 are fixed on the bottom of the car body. The linear motor is a linear induction motor 5, and the linear induction motor 5 is arranged between the vehicle body and the roadbed. The primary of the linear induction motor 5 is fixed on the bottom of the car body, and the secondary is fixed on the roadbed. The positions of the primary and secondary can be reversed. The magnetic levitation device can be a column, such as Figure 24 shown.

Embodiment 2

[0044] Such as Figure 23 As shown, the linear motor is a linear induction motor 5, and the two primary stages of the linear induction motor 5 are fixed on the inside of the motor frame 14 in parallel, and a track is arranged between the two primary stages. The track is the secondary of the linear induction motor 5, along the In the track direction, the motor frame 14 and the magnet frame 10 are arranged at intervals and fixed on the bottom surface of the car body.

Embodiment 3

[0046] Such as Figure 4 As shown, the linear motor is a permanent magnet linear motor 12, the permanent magnet linear motor 12 is set upside down, the bottom of the car body is fixed with an L-shaped bracket 8, and the roadbed is fixed with an inverted L-shaped bracket 9 corresponding to the L-shaped bracket. A permanent magnet linear motor 12 is arranged between 8 and the inverted L-shaped support 9. The secondary of the permanent magnet synchronous linear motor 12 is fixed on the upper end of the L-shaped support, and the primary is fixed on the lower end of the inverted L-shaped support. The permanent magnet linear motor arranged upside down is fixed at the middle part of the vehicle bottom. or as Figure 5 As shown, the permanent magnet linear motor arranged upside down is fixed on both sides of the vehicle body. Other structures are with embodiment 1.

Abstract

The invention discloses a magnetic suspension train which belongs to the field of vehicles. The magnetic suspension train comprises a train body and a rail, wherein a magnetic suspension device and a power source are arranged between the train body and roadbeds, and the magnetic suspension device is a magnetic resistance type magnetic suspension device; yokes I and yoke brackets of the magnetic resistance type magnetic suspension device constitute the rail; and magnets and magnet brackets are fixed at the bottom of the train body. The invention is driven by a linear motor, and the magnets in the magnetic suspension device are arranged in an array mode, thereby having a simple structure; the magnetic suspension device has great magnetic force, and can work at ordinary temperature; the rail comprises the yokes and yoke brackets, thereby having low cost; and the magnetic suspension device does not need power supply in operation, thereby consuming little energy.

Description

technical field [0001] The invention belongs to the field of vehicles, and in particular relates to a magnetic levitation vehicle. Background technique [0002] The maglev train is a non-contact ground running vehicle that uses magnetic force to suspend the train on the track and is propelled by a motor. There are three main types of magnetic levitation mechanisms used in maglev vehicles: constant conduction electromagnetic levitation, superconducting electromagnetic levitation and permanent magnet homopolar repulsion levitation. Normally conductive electromagnetic levitation requires power consumption, complex control technology, and high equipment cost. Superconducting electromagnetic levitation needs to provide an ultra-low temperature environment, high energy consumption, and expensive track construction; although permanent magnet homopolar repulsive levitation consumes less energy, it needs to lay permanent magnetic tracks, which is expensive, complex in layout, and he...
