Problems solved by technology

[0003] However, during the operation of the steel wheel and rail train, the interaction between the wheel and the rail produces vibration and noise, especially when there is a certain irregularity in the line, the vibration and noise will be intensified, and even cause damage to the car body structure, track structure, passengers, etc. Neglected hazards

Embodiment

[0020] Example: such as figure 1 As shown, the permanent magnetic suspension vibration damping and noise reduction device of the train car in this embodiment is composed of a suspension box 1 and a suspension car base 2. The internal cavity section of the suspension box 1 is as follows figure 1 It is shown in an inverted T shape, and a number of second magnets 4 are provided on the inner wall of the suspension box 1. The shape and size of the suspension car base 2 match the shape and size of the inner cavity of the suspension box 1, that is, its shape is also an inverted T shape, and its size is slightly smaller than the inner cavity of the suspension box 1. A number of first magnets 3 are provided on the surface of the suspension car base 2, and the positions of the first magnets 3 correspond to the positions of the second magnets 4 in the suspension box 1. The same magnetic poles of the first magnet 3 and the second magnet 4 are opposed to each other, and the magnetic repulsi...

Abstract

The invention relates to the technical field of train vibration reduction and noise reduction, in particular to a permanent magnetic levitation vibration reduction and noise reduction device for train cars, characterized in that: the device is installed between the train car and the train bogie, including a suspension car base and a suspension box, the base of the suspension car is arranged at the bottom of the train car, the suspension box is connected with the train bogie, the base of the suspension car has a first magnet, and the inside of the suspension box has a second magnet , the base of the suspension car is suspended inside the box body of the suspension box through the magnetic repulsion force generated when the same magnetic poles between the first magnet and the second magnet are opposite, so that the train car and the train There is absolutely no contact between the bogies. The invention has the advantages of simple structure, convenient realization, safety and reliability; during the running process of the train, the transmission of vibration and noise from the bogie to the carriage is completely cut off.

Description

Technical field [0001] The invention relates to the technical field of train vibration and noise reduction, in particular to a permanent magnetic suspension vibration and noise reduction device for train carriages. Background technique [0002] Maglev trains have many advantages. For example, the train runs in suspension above the track, and the track does not touch the vehicle. Not only does it run fast, but it also has low body vibration and noise. The train runs smoothly and comfortably. However, the construction cost of maglev train lines is high, and there are still many problems in safety and reliability of maglev trains. This is the reason why maglev trains have not been developed in large numbers at home and abroad. For example, the braking performance of maglev trains in emergencies is unreliable, not as good as steel-wheeled rail trains. Vehicles on land are relatively dangerous without wheels, because the train has to drop from a large momentum to a standstill, and to...
