Description
Technical field
The present invention relates to traffic transporting technology, is a kind of guide tracked dual guiding steel wheel rail formula high speed rail system that does not derail and the footway formula City Rail Transit System that can change to automatically
Technical background
The military train of France's one row on December 12nd, 1917 is overstepped the limit 543 people's death at the tunnel portal place.
April 3 nineteen fifty-five, Mexico's one row train fell into valley, 300 people's death.
On October 6th, 1972, Mexico's one row derailing was caught fire, 208 people's death.
When I learnt design lathe and commercial production automation line in Xi'an Communications University in 1975, frequent oneself squeezing because allow others get on the bus earlier do not get on a bus; When researching and solving the urban traffic congestion, just know: only with wheel edge and rail top friction guiding and only with exceed wheel more than 2 centimetres the circular arc wheel rim and the arc surface at rail top prevent the train that wheel is derailed: not only can " overstep the limit " but also train " crawling " forward not stopping the friction that wigwag motion, steel wheel of train do not stop on the rail on the rail of ground when walking as snake! And unmanned platen and machine tool guideway; Not only do not allow " crawling ", its project organization has just been stopped the possibility of " overstepping the limit ".
The automobile that design is not overturned is very difficult; But, do not allow the train " derailing " that travels on fixing rail be easy to.
Even to this day, the manned train of 21st century, high speed railway train; Why also as original train with the friction guiding, not only allow that it " crawls " but also allows its harm humans life of " overstepping the limit " why!
For solve existing wheel-rail train two wheels be fixed on the axle can't differential, problem such as wheel-rail wear and tear strongly, is easily overstepped the limit and the high maintenance capacity of energy consumption is big; People are developing the independent wheel rolling stock always, but the bad always solution of the guiding problem of independent wheel.
At present, operate on the overpass High-speed Wheel railway that speed per hour is 350 kilometers; Its wheel track structure is the same substantially with the original low speed train of energy " overstepping the limit "; Not only can not guarantee not derail, more can't guarantee when the burst earthquake, not overstep the limit, do not overturn when happening suddenly hurricane.High speed train on overpass is overstepped the limit and to be rolled under the bridge if travel, and loses more serious.
For the transport solution congested problem, the urban track traffics such as having built subterranean railway that spends huge sums of a lot of cities, but the urban traffic blocking problem remains insurmountable world-famous puzzle together so far.
But in commercial production: single and mini-batch production can only mill with the very low car of capacity rating, full, mill waits general machine tool manual operation production (to be equivalent to the city motor bus in the present city traffic, private car, electric car, subway, taxicar, bicycle etc.), can be with semi-automatic conveyor line production when in batches big, only the available automatic production lines of ability is efficient when in enormous quantities, high quality, low cost, automated production; Big more (it is big more to be equivalent to Forecast of Urban Traffic Flow, crowded more) is welcome more in batches.
Summary of the invention
The objective of the invention is: with the alternative friction guiding that has the wheel rail railway now of Roll action-oriented, the guiding problem and the derailing problem guarantee passenger life security of existing railway, the method that utilization solves the commercial production automation line of commercial production problem in enormous quantities that solve independently rotating wheel from structure solve the city traffic congested problem.
The present invention increases track adjusting wheel and increases with existing rail directed parallel track adjusting wheel guiding on the ground and prevent that track adjusting wheel breaks away from the method that the guide tracked flute profile guided way of dual-side is given prominence on the base of guided way on the same steel wheel rail railway transport vehicle bogie truck that utilizes wheel rim and taper tread and traveling steel rail friction guiding of existing and original train, change the basic structure of existing railway track and wheel hub traffic system, the friction guiding of existing wheel rail railway is become the guiding of rolling, and two wheels on the existing railroad train and axle be fixed together can not differential not merely vertical lathe wheel construction make independent wheel construction into, the taper tread of existing wheel is made into cylindrical tread, the rail rail level that contacts with wheel tread is mounted to horizontal surface at linear portion, some contact the becoming line contact between the existing railway track and wheel hub, the existing steel wheel rail railway system that only can derail with wheel rim friction guiding is become guide tracked dual guiding, the dual guide tracked dual guiding that prevents that rolling stock from overstepping the limit, the high speed rail system of not overstepping the limit of independent wheel cylinder tread.
Guide tracked dual guiding wheel track traffic system is used the track switch that guide rail is arranged, still, because the track adjusting wheel of guide tracked dual guiding wheel track traffic system is higher than walking rail rail level, so the method that also can be used in track switch place disconnection guided way is used existing railway switch.
Guide tracked dual guiding wheel track traffic system wheel rim when cruising is that the safe spare guide frame does not only contact with rail with the track adjusting wheel guiding, only travels at existing track and locates no guided way because of track switch during by existing track switch and lead with wheel rim in novel guide tracked dual oriented vehicle.Increase the derailed high speed railway train length of dual guiding and just can improve capacity on a large scale.
The present invention can also adopt the guide tracked dual guiding wheel track traffic system that only the non-independent wheel of existing railway is transformed into independent rotary conic tread wheel, guide tracked dual guiding wheel track vehicle can be travelled on existing railroad track, and existing railroad train also can travel on guide tracked dual guiding wheel track traffic track.
The present invention can also adopt only increases by 4 track adjusting wheels on existing railroad train bogie truck, increase the flute profile guided way in existing railroad track both sides, disconnects the guide tracked dual guiding wheel track traffic system of guided way at the track switch place; Because wheel is the bogie truck side travel relatively, also gapped between running wheel wheel rim and the traveling steel rail, so guide tracked dual guiding wheel track traffic system not only can dually lead, track adjusting wheel does not contact with guided way when cruising but also can adopt; By the operation scheme operation of the existing railway system, the just existing High-speed Wheel railway system of track adjusting wheel and flute profile guided way ensures the safety facilities that must be equipped with that passenger's person is perfectly safe fully.
In the city, method with the commercial production automation line is designed to the derailed high speed railway track of dual guiding to go in ring, train and platform are lengthened to the same long annular with track from beginning to end, annular over long train from beginning to end is a stop spacing (1000 meters) on circular orbit, the platform that just becomes to overtake of a stop spacing (1000 meters) also is the footway, what also there was a platform function on the footway, street can be provided with small station that the passenger the imports and exports footway formula City Rail Transit System apart from the big dual guiding of capacity arbitrarily, and available shortening train length and the capacity of dwindling the method mediator trade formula City Rail Transit System of train width significantly reduce construction investment; Also can be on the endless track of footway formula City Rail Transit System synchronized operation multiple row the urban rail transit vehicles that can arbitrarily extend and shorten by the operation scheme operation of existing urban track traffic the same with existing track train.
The track adjusting wheel of footway formula City Rail Transit System or road wheel and track adjusting wheel also can be used rubber tire, it is characterized in that: the bogie truck bottom have the one group of guiding wheels bogie truck top that can lead separately also have one group can independent pilot the guiding wheels, can two groups during train driving track adjusting wheel dual guiding or only allow wherein one group of another group that leads is standby and anti-overturning track adjusting wheel simultaneously.
Having on the long platform of footway formula of footway formula City Rail Transit System gets on the bus from here can arrive the somewhere and just in time can arrive the sign in certain place in certain four corners park and shift direction; On each compartment of train of a stop spacing long (1000 meters), also there is this compartment to stop, just in time can be parked in a certain certain transfer place of four corners and can changes to the sign in certain certain place of direction in the somewhere;
Footway formula City Rail Transit System also can build up S. A. transfer footway formula City Rail Transit System; S.
