Description

Permanent magnetism and superconductive suspension car
Technical field
The utility model relates to a kind of magnetically supported vehicle, particularly a kind of permanent magnetism and superconductive suspension car.
Background technology
Excellent properties such as magnetically supported vehicle has noncontact, vibration is little, noise is little, safe, quick, efficient height.The magnetic suspension train technology of Japan and Germany is on the forefront, and especially De Guo magnetic suspension train has been generalized to commercial operation.Magnetically supported vehicle is divided into absorption type and scolds floating by suspended pattern.Germany takes often to lead absorption type, and Japan takes superconduction to scold floating.What is called is often led the magnetic orbit that absorption type promptly attracts roadbed to be provided with below with the electromagnet that is arranged on the train, train is suspended and guiding, advance with synchronous or asynchronous linear motor, Chinese Shanghai is exactly to adopt the absorption type technology of often leading of Germany from Long Yanglu to international airport magnetic suspension train line.So-called superconduction scolds floating promptly when train is run at high speed, and the electromagnetic induction repulsion that utilizes superconduction kicker magnet and track coil to produce suspends train and leads, and advances with linear synchronous motor.
More than two kinds of magnetically supported vehicles (comprise car body, rail, supply line, control system etc., this illustrates that said magnetically supported vehicle is the full name of car and rail, below identical) suspension, guiding and propulsion system technical sophistication, Ang Gui cost extremely, wherein for the suspension that realizes car and guiding and the cost of paying accounts for major part, because rail is very long, the rail expense of building belt coil is high.The operating cost of these two kinds of magnetically supported vehicles is also higher, wants power consumption because often lead the absorption type track coil, and superconduction scolds floating will consume lot of energy could obtain electromagnetic induction repulsion.
For the improvement technology, reduce laid down cost, the invention or utility model patent of many relevant magnetic suspension trains occurred, but actual building cost is still higher, also have big gap from practical application.
Obviously, the practical application principal element of restriction magnetically supported vehicle is a laid down cost, secondly is operating cost.
In order further to improve the technology of magnetically supported vehicle, cost-cutting, I have proposed the application for a patent for invention of " permanent magnetic force vehicle (application number 2006101458597) ", " permanent magnet suspension and magnetic wheel pushing vehicle (application number 2006101706671) " by name, " permanent magnet suspension and soft magnetic wheel pushing vehicle (application number 2006101706633) ", " magnetic suspension electric vehicle (application number 2007100050782) "." permanent magnetic force vehicle " is provided with permanent magnetic wheels and permanent magnetic plate onboard, rail is built with the low inductive material of price, thereby, this magnetically supported vehicle and rail cost are low, because " permanent magnetic force vehicle " realized suspending and guiding by electromagnetic induction repulsion, energy consumption and operating cost and other magnetically supported vehicle are similar.The magnetically supported vehicle of its excess-three item application all is to utilize the repulsion between the permanent magnet at the bottom of permanent magnetism rail and the car to realize suspending and guiding, and the fabrication cost of rail is unlike other magnetic suspension overall height, but energy consumption is little, and operating cost is low.When paying the utmost attention in order to save fabrication cost, can select " permanent magnetic force vehicle ", when paying the utmost attention to, can select above-mentioned its excess-three kind magnetically supported vehicle for energy-conservation or saving operating cost, if the permanent-magnet material cost reduces, select these three kinds of magnetically supported vehicles more satisfactory.But at present, under the still high situation of permanent-magnet material price, how can reduce the cost of magnetically supported vehicle significantly, save operating cost again?
Because the expense of building very long magnetic force rail wants high many than the cost of only car (not containing rail),, should manage to reduce significantly the cost of rail so desire to reduce significantly again the fabrication cost of magnetically supported vehicle.
Summary of the invention
The utility model passes through the superconducting magnet at the bottom of optimal design permanent magnetism rail and the car, solves existing magnetic suspension train and involves great expense, and the operating cost height is used problems such as restricted.
The utility model is realized by following technical scheme.
The utility model is provided with the permanent magnetism rail at interval along the road length direction, the permanent magnetism rail perhaps is set continuously, but the thickness of attenuate permanent magnet, to reduce the consumption of rail permanent-magnet material, drive magnet-wheel or drive coil and at the bottom of car, stagger with the rail opposed bottom surface, the superconducting magnet of magnetic force than existing permanent magnet magnetic force many by force (superconducting magnet can be set up the magnetic field than much higher times of conventional permanent magnet in the large scale space) is set, utilizes magnetic repulsion between the same polarity of permanent magnet and car baselap magnetizer on the rail that car body is suspended and lead.Be noted that permanent magnet on the attenuate rail to a certain degree, be in the requirement of mechanical strength and again during attenuate, can adopt along the road length direction permanent magnet is set at interval, can further reduce the consumption of rail permanent-magnet material.Reduce the consumption of high price permanent-magnet material significantly, just reduced the cost of rail significantly, thereby reduce the fabrication cost of magnetically supported vehicle significantly.
Propelling as for car, magnet-wheel or motor coil can be set onboard [see " permanent magnetic force vehicle (application number 2006101458597) " by name that I have proposed for details, " permanent magnet suspension and magnetic wheel pushing vehicle (application number 2006101706671) ", " permanent magnet suspension and soft magnetic wheel pushing vehicle (application number 2006101706633) ", the application for a patent for invention file of " magnetic suspension electric vehicle (application number 2007100050782) "], utilize the magnetic force of described permanent magnetism rail to realize, although the utility model rail permanent magnetic field has weakened, can obtain desired propulsive force by increasing the quantity that magnet-wheel or motor coil are set onboard, also can consider to be provided with onboard turbofan, the turbojet device is made engine.
We know, the size of car body gained lift force, square being directly proportional of the magnetic induction density that between them, is superimposed as among the gap with magnet at the bottom of rail permanent magnet and the car, so, when assurance is constant to the pairing magnetic induction density value of desired lift force, can reduce the magnetic induction density value of rail permanent magnet in described gap, magnet is in the magnetic induction density value in described gap at the bottom of the car of equivalent increase simultaneously.Because superconducting magnet can be set up the magnetic field than much higher times of conventional permanent magnet in the large scale space, superconducting magnet is set at the bottom of car replaces conventional permanent magnet, can obtain very high magnetic induction density in described gap, therefore the consumption of permanent magnet can be reduced significantly, thereby the cost of rail can be reduced greatly.The utility model comes design-calculated by such thought just.
Like this, although the superconducting magnet that involves great expense is set onboard, increased the cost of car, can because of significantly reducing the consumption of (reducing more than the 50%) permanent-magnet material that rail is very expensive, thereby reduce the cost of rail significantly, the amount that this cost reduces is more much bigger than the amount of the cost increase of car.
The utility model has bigger meaning for the cost that reduces conductivity magnetic levitation transport system has significantly proposed a solution to applying conductivity magnetic levitation transport system.The useful effect of the utility model is at this.
