Description
Technical field
The utility model is related to transport facility fields, and in particular to a kind of double-deck magnetic suspension row of linear motor driving
Vehicle.
Background technology
Double-deck magnetic suspension train is a kind of magnetic suspension train with double-layer structure, and why it is classified as magnetic suspension row
Vehicle is because its type of drive and suspended pattern are similar with conventional magnetic suspension train, i.e., is all to repel each other to suspend and sharp using magnetic pole
It is driven with linear motor.Relative to conventional magnetic suspension train, difference lies in it（Double-deck magnetic suspension train）Than traditional magnetcisuspension
It has floated more than train lower trailer carriage rather than conventional train only has single upper compartment.This makes double-deck magnetic suspension train have two when in use
A space can utilize, i.e., upper compartment and lower compartment.Compared to rise traditional magnetic suspension train at double increase carrying capacity, and
Since double-deck magnetic suspension train uses the mounting means of overhead track, existing motor-car track, high-speed railway rail, city may be mounted at
The upper sheaf space of political affairs highway and highway, can economize the land resource and make full use of space, reducing the construction costs, this
All corresponding technical inspirations are showed no in patent disclosed so far, non-patent literature and practical application.
The suspension system generally use of conventional maglev train is two schemes, and first is to utilize to be mounted on magnetic suspension row
The coil of car bottom simultaneously passes to the sufficiently strong magnetic field of high current generation so as to there is sufficiently large repulsion that magnetic suspension train is made to be detached from rail
Road, which is realized, to suspend；Second is the permanent magnet directly installed in magnetic suspension train bottom, makes itself and the permanent magnet phase interaction on track
Make magnetic suspending train with the repulsion for generating huge.Two schemes have shortcoming, the first scheme is due to whole magnetic
It is generated by hot-wire coil, then in order to which the active force for generating sufficiently large usually requires to pass to high current, not only waste of energy
More there is huge security risk；Second scheme is due to directly using permanent magnet, if the magnetic suspension train in practical application
Bottom sucks magnetic material accidentally, and cleaning is got up will be abnormal difficult.Notably, since employee needs closely to grasp strong magnetic
Make, magnetic radiation caused by strong magnetic will generate health threat.
Magnetic suspension train can theoretically be utilized to the suspended pattern of permanent magnet ledger line circle, based on permanent magnet, coil
Supplemented by suspension system, permanent magnet makes have certain repulsion between double-deck magnetic suspension train and Crane Rail, but deficiency allows double-layer magnetic
Aerotrain suspends completely, controls the suspension of double-deck magnetic suspension train by being superimposed magnetic field caused by hot-wire coil again at this time
Posture.Using this technology, not only coil need not pass to high current, more without using the larger permanent magnet of magnetic radiation, save energy
The raying dosage of service personnel is reduced while source.This is equally in presently disclosed patent and non-patent literature and practical application
