Description

Gliding type train walking system

Technical field

The present invention relates to the railway traffic technical field.

Background technology

The application engineering of current railway traffic has two kinds: the one, and traditional wheel-track type railway technology, moreover be exactly the magnetic suspended railway technology of a new generation.For traditional wheel-track type railway, reached very ripe degree technically.Yet, because himself limitation causes it to be difficult to adapt to socio-economic development to railway transportation, especially to the requirements at the higher level of high speed passenger transportation railway transportation.Such as at first aspect speed, traditional wheel-track type railway is because its train operation is to pass to rail by the power that turning motor rotates drive wheels, makes train operation by " binding force " between wheel and rail.But owing to adhesion factor is that the increase that is accompanied by speed reduces, when adhesion factor is when being reduced to certain value, train wheel will dally, just skid, and causes its running state to worsen.Therefore 300 kilometers speed per hours of this traditional wheeled train have been near the limit of wheel-track type railway speed increase, if per hour want to realize 360 kilometers or 500 kilometers so that faster hyper-speed move that and undertake to do what is apparently beyond one's ability really! Except not satisfying aspect the speed the requirement faster, this wheeled walking system, the power truck that high speed train adopted particularly, its structure complexity very, take also not too comfortable etc., thereby seen traditional wheel-track type railway at mode of motion and further after the critical defect aspect the speed-raising people, it is technical just the sight of hope have been focused on the magnetic suspended railway of novel uniqueness.This magnetic suspended railway has two big basic fundamentals, and the one, the straight line electric machine technology that traction drive adopted, the 2nd, the technology that the electromagnetism that train can be suspended get up repels or attracts.Owing to can make the train operation that suspends, thereby can realize train per hour more than 360 kilometers and even the operation of 500 kilometers hyper-speed, and its traveling comfort and comfort level also greatly raising.But, or else be exactly to adopt the repulsive force of superconducting electromagnet that train is suspended in order to make suspend operation otherwise be exactly to adopt the attractive force of normal conducting magnetic iron that train is suspended of train.It is at car body both sides reversings bottom position place upwards electromagnet to be installed to attract each other with the guide rail electromagnet that is installed in two on track that this first kind is often led mode, from but train is suspended.The magnetic suspended railway of the normal waveguide technology of this employing can only make car body suspend about 1 centimetre because the magnetic force that is produced is little, and employed electromagnet is not only much but also heavier, and the deadweight of vehicle body is increased.Then a kind of superconduction mode then is that superconducting electromagnet is installed ON TRAINS, when vehicle when being installed in ground coil or nonmagnetic metal plate, utilize that the repulsive force between the superconducting electromagnet suspends train on inducing current that the ground coil produces and the car.The magnetic suspended railway of this employing superconductor technology is because the magnetic force that produced is bigger, thereby car body has been suspended about 10 centimetres.But since now high temperature superconductor technology that is that all right is ripe, and adopt the magnetic suspended railway of liquid helium low-temperature superconducting technology to be difficult to drop into commercial operation, just the magnetic suspended railway of this superconduct is can be not applicable now.In addition, no matter be the type of often leading, still the magnetic suspended railway of superconduct exists all because will allow train suspend all that vehicle body is heavier, cost is high and it is bigger than normal to consume energy, and has particularly strengthened shortcomings such as traffic cost thus, is very uneconomic from the commercial off-the-shelf angle therefore.In addition, this magnetic suspended railway is because its special train and track structure, thereby the complexity of its structure is conspicuous, the height of heavy, the cost of vehicle body, and these all are undisputable facts.

Summary of the invention

Purpose of the present invention is exactly the weak point at above-mentioned two kinds of railway technologies, a kind of train walking system that can allow train do gliding motility on special track is provided, because the running gear structure of this train itself is very simple, weight is low weight again, thereby can be corresponding cut down the consumption of energy effectively and cost and be to reduce maintenance cost, thereby also just can cut operating costs, even and this gliding type train per hour also can be done more than 360 kilometers fully and even be 500 kilometers hyper-speed operations quickly, and can realize the networking operation.

The object of the present invention is achieved like this: (comprising the headstock part) is that front and back are equipped with two equal and opposite in directions and position parallel a pair of accordingly (or claiming a group) ski type running gear below every joint compartment of this gliding type train, and be the dragging track of two parallel special " analog-U shaped " rail formulas of corresponding laying on track bed, each below the every joint of this train compartment will be placed into exactly sled on the orbital plane in the dragging track of " analog-U shaped " rail formula at this and do gliding motility.The dragging track of this " analog-U shaped " rail formula, its section is to be

The rectangular rail of shape, the sled of this train are exactly to do gliding motility on the orbital plane in dragging track.Two tops of its " analog-U shaped " rail formula dragging track are that hook-shaped stile then is to be to do steadily to slide on the dragging track of " analog-U shaped " rail formula in order to retrain sled, can be again to block the liquid greasing substance that smears on dragging track can not leak because of the extruding of motion sled.The edge of the tongue shape that stretch out on its both sides then is to use as the dragging track of fixing this " analog-U shaped " rail formula.All to smear the last layer greasing substance equably on the orbital plane in the dragging track of this external every " analog-U shaped " rail formula, also apply the level and smooth material of one deck picture " ice " class, but preferably use senior lubricant under the general condition.Like this when train is driven, every joint compartment of train just can by be mounted in below it front and back totally two to (or claiming two groups) totally four sleds on the dragging track of " analog-U shaped " rail formula that lays, do gliding motility, smear at this moment that just to play at that layer greasing substance on the dragging track be the effect that reduces the sliding-frictional resistance that sled produced when sliding.This each sled all is to adopt those hard solid materials to manufacture, but is preferably to adopt steel to manufacture under condition now.All is that to connect with identical wing plate parts be further reinforcing at each to the specific location between the sled inboard, the wing plate parts that whole erection is good are to be parastate with cabin floor and orbital plane, and it is the shape of similar aircraft wing that these each wing plate parts all want design and manufacture to become protruding above the lower plane, in order to increasing a kind of lift that can offset quite a few car body weight, so just can further reduce the sliding-frictional resistance that train is produced when sliding at a high speed to the train that slides at a high speed.What this also will illustrate a bit be, below every joint compartment, just be not merely able between each is to sled, be provided with to play and reinforce and the wing plate parts that produce these two kinds of effects of lift, also can be to be provided with a plurality of what singly hoist the power effect is the wing plate that rises as the wing plate shape if necessary below every joint compartment, the wing plate that rises of this wing plate shape is the bottom of being fixed, be suspended in the compartment by two cantilevers, its objective is and to offset the weight in every joint compartment fully that the good sliding-frictional resistance that train is produced is to reduce to negligible degree when sliding at a high speed.Can realize the networking that intersects in length and breadth on a large scale for this gliding type railway in addition runs, and specific location that will be at the bottom of the double-ended vehicle of gliding type train (can be headstock and or tailstock bottom laterally with forward midway location) be that track adjusting wheel parts will respectively be installed, when process needed the track switch guide rail of lane change, track adjusting wheel will make the gliding type train successfully finish lane change under the guiding of track switch guide rail and travel like this.

Train walking system of the present invention is owing to be to have adopted below every joint compartment of train two groups of sleds to be installed and to be the practice that is laid on the track bed with this dragging track of purpose made " analog-U shaped " rail, thereby just can allow this gliding type train be to do gliding motility on this dragging track by this running gear of sled.It is very simple that the train running gear of obviously this " ski type " structure with respect to the running gear of the running gear of wheeled train and magnetic suspension train becomes, and it is light a lot of that weight is also wanted.And on dragging track, smear one deck greasing substance, just can reduce the sliding-frictional resistance of making the gliding motility train widely, being provided with between every pair of sled is to reinforce the wing plate parts that sled more can produce lift again, then just can be to effectively utilize very much the aerodynamic energy that train is produced when sliding at a high speed, and be translated into the lift that to offset train gravity, and then just can further reduce the sliding-frictional resistance of making the gliding motility train, and can be to be reduced to negligible degree with sliding-frictional resistance.This can eliminate the influence of sliding-frictional resistance, has also reduced energy consumption with regard to certain degree ground.Aspect speed, also adopt linear motor to drive operation if can eliminate the gliding type high speed train of sliding-frictional resistance basically, that per hour just also can do 360 kilometers and even be hyper-speed operation more than 500 kilometers as magnetic suspension train.Aspect the networking operation,, just can realize the networking operation that intersects in length and breadth on a large scale because this gliding type train is that track adjusting wheel has been installed especially, thereby just can do lane change and travel under the guiding of rail switch.In a word, this gliding type railway technology has not still had the speed advantage of magnetic suspended railway technology concurrently, also had the advantage of wheel-track type railway technology aspect the networking operation simultaneously concurrently, and himself also have safety and comfort, simple in structure, in light weight, capacity usage ratio is high and be the plurality of advantages that maintenance cost is low, energy consumption is low, operation cost is lower.Therefore, the railway operation technology of this gliding type is undisputed to be state-of-the-art, and it is the most desirable that also yes.
