Description
Technical field
The present invention relates to a kind of magnetic-levitation train that makes and follow track in the process of moving all the time, prevent the running mechanism of derail.
Technical background
Aerotrain is a kind of track transporting tool that is different from other conventional track traffic device, wherein running mechanism is the core of magnetic-levitation train structure, it is different fully with existing rail train and subway wheel carrier structure, rail train (containing subway) is the friction generation motion by wheel track, magnetic-levitation train is by being installed in the suspension on the running mechanism, the magnetic field that guidance magnets produces, lift force, guidance force, longitudinal force being passed to the compartment, drive the magnetic-levitation train motion.And running mechanism is to install and fix support, transmitted load for suspension, guiding, brake magnet provide; Realize mobile decoupling by the secondary suspension device, assurance Fleeting track.Because car body and interorbital do not have mechanical contact, car body " suspension " orbits, speed very high (speed per hour is above 500 kilometers) during operation.Therefore, people often are " low altitude aircraft that does not have wing " with the magnetic suspension train analogy.Slide on the ground with wheel earlier when taking off, when accelerating to a certain degree, wheel indentation " machine tripe " is gone up to the air.The magnetic suspension running mechanism that the floating train of Japan adopts be exactly therewith similar " repulsion formula " the Ci Xuan Fu Auxiliary of aircraft help Trucks wheel running gear.It uses the superconductor that repels each other with magnetic, is produced repulsion and is made car body keep come-up by Trucks body and ground Zhi Inter with the coil after the energising again.But When Trucks Jing Zhi is Time, and can not changed by the flux of what coil produces the magnetic of homopolarity, so it is very similar to the situation of aircraft to utilize the floating Trucks Zai Jing Zhi Time And of the magnetic of repulsion can not float Lai .Must start earlier by Shall by what in addition, make coil give birth to inducing current order row Trucks and suspend, therefore be listed as on the Trucks and must help the Trucks wheel by Shall You Auxiliary, as " taking off " usefulness with " landing " .Qi Dong Time reaches 40 kilometers Yi Shang Time with the moving, Dang Time speed of Trucks wheel Tapes, and the row Trucks, Ci Time wheel that just begins to suspend is just packed up automatically.Because structural reason, car body can not produce suspension at ordinary times, can only be as the aircraft wheel support, after the starting when the speed of a motor vehicle reaches per hour more than 80 kilometers, the magnetic field of faradic magnetic field and superconducting electromagnet is mutually exclusive to suspend train, and hoverheight can be about 10cm, and car body suspends just as aircraft.When train driving, because the electromagnetic induction in the aluminium ring, the magnetic field of superconducting magnet is cut by ground aluminium ring cutting on the car.When train deceleration or parking, the inducing current in the aluminium ring diminishes or is zero, and the buoyancy deficiency overcomes the weight of train, so still need wheel be installed so that support train, when the train high-speed motion, wheel is withdrawn automatically.
Summary of the invention
The objective of the invention is to avoid above-mentioned prior art " repulsion formula " Ci Xuan Fu Auxiliary to help the weak point of Trucks wheel running gear, provide a kind of and realize mobile decoupling by the floating car secondary suspension device of magnetic, guarantee the Fleeting track, satisfy the performance requriements of magnetic-levitation train by minimum radius of horizontal curve 350m, minimal vertical curve radius 530m and climbing performance from dead stop 10%, isolation can prevent the running mechanism of derail from the nothing wheel magnetic suspension of the vibration of track and device self.
