Description

New suspension propulsion two-in-one magnetic levitation system

Technical field

The invention belongs to the technical field of magnetic levitation vehicles, and relates to a novel suspension propulsion two-in-one magnetic levitation system.

Background technique

The magnetic levitation vehicle is a modern high-tech vehicle that uses electromagnetic force to achieve contactless suspension and guidance between the body and the track, and then uses a linear motor to drive the vehicle. Because the vehicle has no frictional contact with the track during traction operation, it fundamentally overcomes the problems of traditional vehicle wheel-rail adhesion limitation, mechanical noise and wear, and thus has high speed, energy saving, easy cornering, climbing, flexible line selection, It has many advantages such as strong adaptability, no pollution, low noise, safety, comfort, and low maintenance. It is an ideal land vehicle that people have always dreamed of. It is also a new type of high-speed modern transportation that has been vying for development in recent economic powers in recent decades. tool.

At present, there are two main types of propulsion systems for maglev trains:

The first propulsion system is composed of a drive winding in the middle of the track lane and an in-vehicle propulsion magnet in the middle of the train bottom. The stator (ie, the drive winding) of the linear motor is continuously distributed along the track, and the rotor as the vehicle propulsion magnet is fixed on the train. The thrust is generated by the alternating current that drives the windings on the track. This kind of propulsion system adopts segmental power supply, about 2~3km is a power supply area, and each power supply area is powered by the power supply cabinet distributed along the line, so that the drive winding and the vehicle propulsion magnet or the power integrated winding under the train generate electric induction and drive For non-contact traction and braking, since the drive windings of the propulsion system are installed on the rails, the trains do not need feeders and pantographs.

The second propulsion system is composed of a propulsion magnet in the middle of the track lane and an in-vehicle drive winding in the middle of the train bottom. The stator of the propulsion magnet is continuously distributed along the track, and the rotor (ie, the drive winding) as a linear motor is fixed on the train, and the thrust is Generated by the alternating current of the train drive winding, the drive winding and the propulsion magnet or the power integrated winding above the track generate electric induction to drive the train. Since the drive winding of the propulsion system is installed on the train, the magnetic suspension vehicle needs feeders and sets when operating. Electric bow.

The above two propulsion systems are complex in structure and high in cost.

In short, the existing magnetic levitation vehicles generally have shortcomings such as large investment, high cost, high technical requirements, complicated propulsion system and suspension system.

Summary of the invention

In order to overcome the above disadvantages of the prior art, the present invention provides a novel suspension propulsion two-in-one magnetic levitation system that does not require a special guiding system, and has the advantages of simple structure, low cost, energy saving and environmental protection, low technical requirements, high safety and the like.

The technical solution adopted by the present invention to solve the technical problem thereof is: a novel suspension propulsion two-in-one magnetic levitation system, comprising a vehicle magnet, a lane aluminum plate and a track assembly, wherein the vehicle magnet is disposed at the bottom of the vehicle body; the lane aluminum plate is laid in the lane The track assembly mainly comprises an endless track disposed on the vehicle for walking, the track comprising a track shoe, a sprocket, a track pin, a rubber collar, an end connector and a screw nut, wherein the track shoe is composed of a track magnet and The metal casing is formed, the track magnet is embedded in the metal casing, and the track plate is connected with the sprocket to form a track link. The N and S magnetic poles of the track magnet are uniformly oriented, one facing the track and one facing the track, and the track is horizontal when moving. Give the ground a force, and the ground gives the crawler a reaction force. This reaction force causes the car body to move. After the car body starts to move, the crawler magnet and Magnetic interaction occurs between the aluminum plates of the lane. According to Lenz's law, the relative motion of the magnet and the conductor will generate an induced current in the conductor. When the crawler magnet moves relative to the aluminum plate of the lane, an induced current is generated in the aluminum plate of the lane, and the magnetic field of the induced current is generated. Contrary to the magnetic field direction of the track magnet, the repulsive force between the lane aluminum plate and the track magnet, so that the track will be suspended from the aluminum plate surface of the lane, the entire track assembly and the car body will also float away from the aluminum plate surface of the lane.

The track assembly includes a crawler belt, a driving wheel, a guide wheel, a roller, a load bar, a carrier roller and a tensioning device.

The track assembly is at least one.

A crawler frame for supporting the vehicle body is disposed in the middle of the crawler belt.

The crawler frame is provided with staggered load bars and roller wheels, and the track is provided with a sprocket which can bear the track to avoid the rise of the track.

The vehicle magnet, the track magnet includes a permanent magnet, an electromagnet, a superconducting magnet, a rare earth permanent magnet, or a combination of any of the above.

The vehicle body may be a scooter, a bicycle, an electric vehicle, a motorcycle, a car, and a train to which a track assembly is attached.

The rear end of the vehicle body can also be equipped with a car, and each car is provided with a vehicle magnet.

The beneficial effects of the invention are:

1. Suspension and propulsion in one, no special guiding system is required. When the power of the engine is transmitted to the driving wheel on the track assembly, the driving wheel rotates the track. According to the action of the force and the reaction principle, the track gives the ground a force in the horizontal direction, and the ground gives the crawler a reaction force. The reaction force promotes the new suspension propulsion two-in-one magnetic levitation system and The magnetic suspension vehicle movement of the new suspension propulsion two-in-one magnetic levitation system is installed. After the magnetic levitation vehicle starts to move, the track magnet and the vehicle magnet respectively generate a magnetic interaction with the aluminum plate of the lane. According to the relative movement of the magnet and the conductor, the principle of inducing the current that hinders the movement of the magnet is generated in the conductor (楞定 law), when the track magnet When the vehicle magnets move relative to the aluminum plate of the lane, the induced current is generated in the aluminum plate of the lane, and the induced current generates an induced magnetic field. The induced magnetic field is opposite to the magnetic field of the track magnet and the vehicle magnet. The induced magnetic field is like the air supported by the airplane. The hovercraft relies on the air cushion and the water that the ship relies on. The crawling track (ie, the magnetic track) and the vehicle magnet are not subjected to the frictional resistance of the ground, but are subjected to the electromagnetic repulsion and electromagnetic resistance of the induced magnetic field emitted by the aluminum plate lane. . As a result, the track will be suspended from the lane aluminum plate. The new suspension propulsion two-in-one magnetic levitation system and the magnetic levitation vehicle equipped with the new suspension propulsion two-in-one magnetic levitation system are also suspended by leaving the lane aluminum plate. The crawler belt continues to rotate, and the electromagnetic repulsion of the induced magnetic field between the aluminum plate of the lane and the track magnet and the vehicle magnet continues to suspend. The electromagnetic resistance of the induced magnetic field promotes the suspension of the new suspension propulsion two-in-one magnetic levitation system and the new model. The magnetic levitation vehicle of the suspension propulsion two-in-one magnetic levitation system advances. When the rotational speeds of the left and right crawler belts are the same, the induced magnetic fields (ie, electromagnetic repulsion and electromagnetic resistance) generated by the relative movement of the left and right magnetic crawler tracks and the aluminum plate lane are equal, so the magnetic suspension vehicle with the new suspension propulsion two-in-one magnetic levitation system is installed. Straight ahead; if the speed of the left track is faster than the speed of the right track, the induced magnetic field generated by the relative movement of the left magnetic track and the aluminum plate lane is greater than the induced magnetic field generated by the relative movement of the right magnetic track and the aluminum plate lane, the vehicle then Right yaw; the same principle, if the speed of the right track is faster than the speed of the left track, the vehicle will deflect to the left; the track will rotate in the opposite direction, after the vehicle Retreat. This is similar to the principle of forward and steering of ordinary crawler cars and tanks, that is, the thrust of the engine is pushed by the thrust of the engine to realize the forward, backward, left turn, right turn, etc. of the vehicle;

Second, the structure is simple, which solves the complex structure of the suspension and propulsion system of the traditional magnetic levitation vehicle, and needs the three structural systems of propulsion, suspension and guidance. The suspension and propulsion are combined into one, no guiding system is needed, and the system structure is greatly simplified. The lane of the new suspension propulsion two-in-one magnetic levitation system is also very simple, only 1-2cm thick aluminum plate (or non-magnetic metal plate such as copper plate). Moreover, the vehicle magnet and the track magnet can be either permanent magnet or electromagnet. When the permanent magnet is used as the vehicle magnet and the track magnet, the structure and principle of the entire suspension propulsion system will be simpler, the system reliability is stronger, and the construction is more convenient. , maintenance is simpler;

Third, the technical requirements are low, the new suspension propulsion two-in-one magnetic levitation system and the magnetic levitation vehicle equipped with the new suspension propulsion two-in-one magnetic levitation system do not need a guiding system, only need to assemble a set of magnetic crawler belts, the crawler belt can be long or short, according to The specific model is tailor-made, short less than 1 meter, just need to be placed or installed in the front or rear wheel position of the car. The track can also be a few meters long, extending from the front wheel to the rear wheel. The magnetic repulsion force generated by the relative movement of the magnet, the track magnet and the aluminum plate of the lane is suspended and propelled, and the principle and structure are simple, so the technical requirements are low;

Fourth, the low cost solves the problem that the cost of the magnetic levitation vehicle is too high and difficult to promote. The suspension and propulsion of the new suspension propulsion two-in-one magnetic levitation system are combined into one, no guiding system is needed, the engineering cost is greatly reduced, and the lane is very Simple, just lay a thin layer of aluminum on the roadbed, thickness 1-2cm. In addition, traditional roads (including highways) can be upgraded with a thin layer of aluminum or non-magnetic metal. The board is fine. Aluminum is abundant in the earth and has a wide range of sources. The most abundant elements in the earth's crust are oxygen (46.6%), silicon (27.7%), aluminum (8.1%), and iron (5.0%). The reserves of aluminum in the earth's crust are more than Iron is the most abundant metal element on earth. It is also possible to develop an inexpensive aluminum alloy magnetic conductive material;

5. Solving the problem that the magnetic levitation vehicle can not be separated from the guide rail or the track, completely get rid of the hard constraint of the guide rail or the track, and become a soft constraint, so that the overtaking and lane change of the magnetic levitation vehicle are no longer a problem, and the car wants to overtake the vehicle. You can overtake, how to go if you want to go, which lane you want to go to which lane. Because the insulating material such as non-magnetic asphalt cement is embedded between the lane aluminum plate lane and the magnetic suspension aluminum plate lane, the magnetic field on the adjacent magnetic suspension aluminum plate lane can be prevented, and the insulating material forms a line, which looks like ordinary road lanes and lanes. A white line or a yellow line between the lines. The magnetic levitation vehicle that floats on the magnetic levitation lane, where it travels, where the magnetic field moves, just like the hovercraft is floating on the air cushion. Where is the hovercraft, where the air cushion appears, and the plane is flying in the air, the air is Buoyancy is also a drag, and it is like a ship sailing in the water. Water is both buoyant and resistance. Overtaking and lane change are also like overtaking, changing lanes between hovercrafts, airplanes, ships, as long as the vehicles maintain an appropriate distance, the mutual influence is basically negligible;

6. Solving the problem of connecting with the existing public transportation, the new suspension propulsion two-in-one magnetic levitation system and the magnetic levitation vehicle equipped with the new suspension propulsion two-in-one magnetic levitation system can be freely switched on the ordinary road lane and the aluminum plate lane. Fully integrated with existing public transportation. In the future, ordinary road lanes can be upgraded. As long as a thin layer of aluminum plate is laid on the ordinary road lane, it can be upgraded to an aluminum plate lane, and an aluminum plate lane can be separated on the ordinary road to make the ordinary lane and the aluminum lane. Parallel

VII. Energy saving and environmental protection, because the new suspension propulsion two-in-one magnetic levitation system and the magnetic levitation vehicle equipped with the new suspension propulsion two-in-one magnetic levitation system are suspended, there is no contact with the ground, and thus there is no wheel-rail contact and friction noise; At the same time, since the car body is suspended, there is no wheel-rail frictional resistance, only electromagnetic resistance, so the propulsion power consumption is low. In addition, the vehicle magnet and the track magnet of the novel suspension propulsion two-in-one magnetic levitation system can adopt permanent magnets. When the vehicle magnet and the track magnet adopt permanent magnets, the suspension consumes almost no power except eddy current loss. When the conditions are ripe, the electromagnetic energy generated in the aluminum plate lane can be collected to provide illumination for all the street lamps in the lane, and can be connected with the existing power grid to send excess power in the lane to the power grid;

Eight, the levitation force is large, the entire magnetic suspension vehicle equipped with the new suspension propulsion two-in-one magnetic levitation system can be equipped with a vehicle magnet at the bottom, and the vehicle magnet and the crawler magnet simultaneously provide a suspension force, so the levitation force can be very large. Of course, for a light weight vehicle such as a car, the vehicle bottom can also be free of the vehicle magnet when it is not necessary, and the track magnet can be suspended only;

9. High safety, the suspension force of the new suspension propulsion two-in-one magnetic levitation system and the magnetic suspension vehicle equipped with the new suspension propulsion two-in-one magnetic levitation system is the speed of relative movement of the crawler magnet, the vehicle magnet and the lane aluminum plate. It is determined that the greater the vehicle speed, the larger the levitation force and the larger the levitation gap; the smaller the vehicle speed, the smaller the levitation force and the smaller the levitation gap. As long as the speed of the vehicle reaches a certain level, it can be suspended in a relatively large suspension gap without contacting the magnetic levitation lane. Moreover, even if the drive power system fails or the line suddenly loses power, the high-speed vehicle has an inertial motion before stopping the motion, and the inertial motion can also generate a magnetic repulsion between the vehicle magnet and the lane aluminum plate. The repulsion becomes smaller as the vehicle speed becomes smaller, so the levitation force is also gradually smaller, and there is no sudden collision of the suspension force with the lane. For the maglev train, the vehicle can also be equipped with a large-capacity battery or a charging treasure as an emergency power source when the power is suddenly turned off;

10. The new suspension propulsion two-in-one magnetic levitation system and the magnetic levitation vehicle equipped with the new suspension propulsion two-in-one magnetic levitation system are suitable for long-distance transportation between cities and cities, and for urban groups and urban interiors. If you are doing urban internal traffic, you only need to build an elevated road or excavate an underground tunnel over the city. In addition, the magnetic suspension series can be easily used in parks and amusement parks for children to play, such as magnetic levitation scooters and magnetic levitation. Karting, small magnetic levitation racing, small magnetic levitation vehicles, small maglev trains and other play models.

In short, the new suspension propulsion two-in-one magnetic levitation system and the magnetic levitation vehicle equipped with the new suspension propulsion two-in-one magnetic levitation system have the advantages of simple structure, low cost, low technical requirements, no need for the vehicle to be strictly bound to the track, energy saving, safety and safety. Many advantages, so that the magnetic levitation traffic is truly simplified, low-cost, and practical, it will open a new era of magnetic levitation traffic, and has epoch-making significance.
