Abstract

The invention relates to an air cushion train, which comprises a streamline train body, an air cushion track, a limit wheel, a limit track, a suspension rail, and a turbine jet engine, wherein it utilizes the ground effect of aerodynamic theory; when train moves on the air cushion track, the air compressed by train head will be wedged into the bottom of train to form air cushion; when the mph of train is 250kilometers, the compressed air cushion can suspend the train from the rail, to match relative limit track, limit wheel, and drawn by jet engine, to realize high-speed stable motion. The inventive air cushion train has simple structure, low cost, high carrying load, low energy consumption and the speed as magnetic levitation train.

Description

Aerotrain

Technical field

The present invention relates to a kind of high speed train, particularly relate to a kind of aerotrain.

Background technology

The speed-raising of wheel-rail train is subjected to the restriction of the binding force of wheel and rail, and the speed-raising upper limit can only reach about 300 kilometers/hour, and speed is undesirable, and the speed of a motor vehicle of magnetic suspension train is very fast, but cost is too high at present.

Summary of the invention

The technical problem to be solved in the present invention provides a kind of high-speed cruising, aerotrain that cost is lower.

Solve its technical matters, the present invention solves by the aerotrain that following structure is provided, this aerotrain comprises fleetline body, position-limited wheel, limit guide rail, turbojet, built on stilts rail, air cushion track, its operation logic is to utilize aerodynamic ground effect principle, along with train moves ahead in the air cushion track, an air part of being pushed by headstock is wedged under the train car, form air cushion, when the speed of a motor vehicle reaches more than 250 kilometers/hour, be subjected to the headstock extruding and air cushion at the bottom of the wedging car just can be with the train holder from the rail suspension operation; Be equipped with corresponding safe limit guide rail, position-limited wheel, just can realize train high speed, smooth running with the jet engine traction.

The invention has the beneficial effects as follows that train is as aircraft-in-ground-effect, the speed of a motor vehicle is fast; Train running resistance on air cushion is little, the saving in power energy; Train operation is by the spacing wheel track guiding of safety, safety performance height.

Specific implementation method

Train length is more satisfactory with 12 joint compartments, oversize before and after the air-cushion pressure in joint compartments differ too big, the tailstock adds fairing, the junction, compartment seamlessly transits, and makes train outside face integral body be stream line pattern, wheel, position-limited wheel only reveal 3 centimetres of circle of contacts, reduce air resistance.

Wheel (4) is still used conventional passenger train wheel, and aerotrain can be moved on common railway at a slow speed the time, and facility is built at shared station etc.

Be furnished with generator set supply electric power on the train, make all position-limited wheels all become the active rotation wheel, rotational line speed is similar to train running speed, to reduce the mobile friction drag of position-limited wheel and guide rail.

The interior rail in air cushion track (20) (14) is built on stilts to be depended on highly that train car spirit pad need be contained in and will reach the air leakage amount of revealing from the seam (24) that loses heart in the unit time that train passes through under the situation that guarantees air pressure, common about 1 meter high, the side wall in air cushion track (13) intensity must can be born air-sprung air pressure, and the conservative factor that doubles is arranged; Compartment raising force when the intensity of support (8) and compartment suspended guidance rail (7) will be can kept under control the train zero load, at least 5 tons of each suspension position-limited wheel wheel points, lateral confinement position guide rail (6), (9) intensity will be stood natural wind and act on the impulsive force in compartment and the centnifugal force of turn inside diameter, both sides support and top cover all cover with wire netting, avoid birds to enter the track.

Train draws with turbojet (18), and the 600 kilometers speed per hours in 12 joint compartments have a high-power turbo jet engine just enough; Can produce the power that headstock is pressed down because of the tractive force shearing action, so being installed on the driving engine both sides, short limb (19) produces lift to offset downforce, but establish the wheel of post against the wind (16) that rise and fall are regulated before the headstock, the post wheel rises and has just driven the big angle that facings the wind of powerful soft plate (21) accent that facings the wind, thereby increase the compression tolerance in wedging air cushion track, otherwise then reduce compression tolerance.

The compartment position-limited wheel all has suspension system, the position-limited wheel that alleviation causes because of crosswind and the collision of guide rail, position-limited wheel and guide rail are stayed 1 centimetre gap, reducing running resistance, the suspend hoverheight in spacing guide rail (7) restriction compartment of compartment 3 centimetres away from rail is advisable be so that wheel is unsettled, do big according to compartment situation position-limited wheel wheel footpath as far as possible, to subtract wheel speed, the installation error of limit guide rail must be little, with the contact vibrations of minimizing with position-limited wheel.

The air cushion superpressure plate (12) that loses heart can upwards stir as coaxial type, push down with torsion spring, when because of factor affecting such as typhoon impacts, the tolerance that enters the air cushion track is too many, air cushion air pressure is too high when surpassing the design bending strength of torsion spring, the plate that loses heart just upwards opens, discharge unnecessary tolerance, to guarantee that air-sprung air pressure is in scope of design, the outer edge of disappointing plate tumbles at least 2 centimetres of soft materials, avoiding and the side wall hard collision, lose heart plate and side wall only stay 1 centimetre of slit, and each carriage weight of train acts on air-sprung pressure and wants basically identical.

The aerotrain turnover moves on common railway at a slow speed during the station, entering the air cushion track quickens, the speed of a motor vehicle reaches 250 kilometers/hour, facing the wind the compressed gas air cushion in plate place wedging air cushion track by headstock just can be with the car holder from steel rail suspending, the post wheel that regulate to facing the wind while quickening makes the pressurized air in wedging air cushion track reach air inlet, disappointing balance, and the train high-speed smooth is moved.Meet emergency situation, the post wheel against the wind that descends does not at once have the air wedging, has not just had air cushion, and train is fallen on the rail, and the while makes expansion of brake bar and side wall drag friction plate (10) friction that car is checked to brake bar (25) inflation of expanding.
