Emergency braking type maglev train

Abstract

The invention relates to an emergency braking type maglev train. The emergency braking type maglev train includes a driver's cabin, a compartment and a power supply system, and an L-shaped pinch plate is installed on the bottom of the compartment, and the pinch plate includes a The support vertical plate at the bottom of the carriage is equipped with driving magnetic strips equidistantly on the support vertical plate; the driving magnetic strip is matched with the driving electromagnetic unit on the rail; a support horizontal plate is fixed at the lower end of the support vertical plate, and Horizontal braking shafts are equidistantly arranged on the top, and damping wheels and damping sheets are sleeved on each of the braking shafts; a suspension magnetic strip is installed in the radial direction of each of the damping wheels, and the suspension magnetic strip and the rail The suspended electromagnetic units on the energized poles attract each other; the maglev train can provide effective braking capacity when the rail or train fails, and at the same time provide emergency energy supply for passengers to ensure the power communication and lighting in the train. Provide guarantee for the life safety of passengers.

Description

technical field [0001] The invention relates to a magnetic levitation train, in particular to a magnetic levitation train which is convenient for braking after a power failure. Background technique [0002] Maglev train is a popular tool in today's railway transportation. Maglev technology can greatly reduce the frictional resistance between the train and the rail, and provide an important guarantee for the speed increase of railway transportation; the train and the rail are suspended without mechanical friction, which can greatly increase the speed of Reducing wear and energy consumption has broad prospects for development; however, maglev trains also have technical problems that need to be solved, one of which is the braking problem of maglev trains during power outages; the power source of maglev trains is the alternating change of the magnetic field direction on the rails The electromagnetic unit drives the train to move forward and brake. The source of the levitation fo...

[0002] Maglev train is a popular tool in today's railway transportation. Maglev technology can greatly reduce the frictional resistance between the train and the rail, and provide an important guarantee for the speed increase of railway transportation; the train and the rail are suspended without mechanical friction, which can greatly increase the speed of Reducing wear and energy consumption has broad prospects for development; however, maglev trains also have technical problems that need to be solved, one of which is the braking problem of maglev trains during power outages; the power source of maglev trains is the alternating change of the magnetic field direction on the rails The electromagnetic unit drives the train to move forward and brake. The source of the levitation force is to make the train vacate through the repulsion of the same pole or the attraction of the opposite pole of the electromagnetic poles; when the circuit is suddenly interrupted, the levitation force of the train disappears, and the train will fly In a state of out-of-control, the high-speed train has great inertia. The high-speed friction between the train and the rail will increase the loss of the car body. At the same time, the braking force of the train will also disappear, and the braking function will be lost. In case of derailment and other situations, the life safety of passengers is seriously threatened; especially when the train has a circuit failure, the communication system, power system, braking system and lighting system in the train may be threatened, which is very likely to cause the masses to lose control. big security risk
