The electromagnetic railcar is safe and stable in use, the laying difficulty of the rails and the cables is small, no cables or other lines are laid above the railcar body, the height of other passing vehicles is not required to be limited, and passing of the other vehicles is not affected.
Description
Technical field
The present invention relates to a kind of vehicle, special, be a kind of tramway train.
Background technology
In life, common are rail electric car and utilize rail to make ground wire, by the cable supply direct current (DC) that is positioned at electric car top, this tramway train as propulsion source, increases the acceleration that electric current can be realized electric car by DC motor, oppositely applies electric current and realizes brake; The cable laying of this tramway train, except increasing difficulty of construction and waste resource, has also limited the height of a lot of locations traffick aloft, is running into the inclement weathers such as strong wind simultaneously, and cable is easy to damage, and personal safety is worked the mischief.
Summary of the invention
For the problems referred to above, the invention provides a kind of electromagnetism railcar, this electromagnetism railcar is used safety, stable, track and cable laying difficulty are little, car body top, without track layings such as cables, does not need to limit the height of other trafficks, does not affect other vehicle current.
For addressing the above problem, the technical solution adopted in the present invention is as follows: this electromagnetism railcar includes a guide plate passage that longitudinally runs through car body, is positioned at vehicle bottom; In the periphery of guide plate passage, along it, be longitudinally equidistantly provided with coil, the distance between adjacent described coil is greater than the twice of loop length; Two joints of described coil are symmetricly set on the both sides foremost of every circle coil; Two track laid inside of described railcar have cable, symmetrical on two cables, the metallic contact that has been equally spaced sheet, and described metallic contact sheet length is less than described loop length; Distance between adjacent described metallic contact sheet is greater than the distance between adjacent described coil; In the central authorities of track, lay the guide plate that the described guide plate passage of a width and railcar bottom matches; On described guide plate device have with described metallic contact sheet isometric and one by one over against permanent magnet, the magnetic line of force direction of the magnetic line of force direction of this permanent magnet during with described coil electricity is identical.
The invention has the beneficial effects as follows: the guide plate of track centre is positioned at the guide plate channel interior of railcar; Because the distance between adjacent described metallic contact sheet is different from the distance between adjacent described coil, so total some coil in railcar bottom contacts described metallic contact sheet; During described wiring metal contact disk on coil connectors contact cable, coil electricity, according to the magnetic effect of electric current, coil inside and produce magnetic field around, the permanent magnet in magnetic action sucking coil the place ahead; Under the effect of magnetic field force, railcar travels forward; When permanent magnet is positioned at coil central authorities, coil joint is foremost separated with the metallic contact sheet of permanent magnet both sides, and circuit disconnects, and magnetic field disappears; Because the distance between adjacent described metallic contact sheet is different from the distance between adjacent described coil, thus there are all the time coil and metallic contact sheet to join, thus keep power; Railcar adopts conventional brake system to realize and stops.The present invention is by cable laying portion in orbit, and difficulty of construction is less; This structure not only can be protected cable, takies street area few simultaneously, need not limit the height of traffick; This electromagnetism railcar is jointly fixing, more stable under steam by track and guide plate.
As preferably, the adjustable resistance of connecting on described coil; By changing resistance value, change the current value in coil, electric current can affect the magnetic field producing in coil, thereby controls the speed of railcar.
As preferably, the distance between adjacent described metallic contact sheet and the distance between adjacent described coil are than being 3:2; The coil longitudinally installing along guide plate passage on railcar has 5; So that assurance railcar bottom always has coil connectors to contact with metallic contact sheet, thereby produce power.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of railcar in one embodiment of the present of invention.
Fig. 2 is the schematic diagram of one embodiment of the present of invention middle orbit.
The specific embodiment:
Embodiment
In the embodiment shown in Fig. 1, Fig. 2, this electromagnetism railcar includes a guide plate passage 1 that longitudinally runs through car body, is positioned at vehicle bottom; In the periphery of guide plate passage 1, along its longitudinally equidistant device, there are 5 coils 2, the distance between described adjacent windings 2 is greater than the twice of loop length; Dotted line in Fig. 1 represents to have omitted coil sections; The joint 21 of described coil 2 is arranged on the both sides foremost of every circle coil; On described coil 2, be in series with adjustable resistance; Two track 3 laid inside of railcar have cable, symmetrical on two cables, the pair of metal that has been equally spaced contact disk 4,4 ＇, and described metallic contact sheet 4,4 ＇ length are less than described coil 2 length of railcar guide plate passage 1 periphery; Distance between adjacent described metallic contact sheet 4 and the distance between adjacent described coil 2 are than being 3:2; In the central authorities of track 3, lay the guide plate 5 that the described guide plate passage 1 of a width and railcar bottom matches; On described guide plate 5 device have with described metallic contact sheet 4,4 ＇ isometric and one by one over against permanent magnet 51, the magnetic line of force direction of the magnetic line of force direction of this permanent magnet 51 during with 2 energising of described coil is identical.
The guide plate 5 of track 3 central authorities is positioned at guide plate passage 1 inside of railcar; Because the distance between adjacent described metallic contact sheet 4,4 ＇ is different from the distance between adjacent described coil 2, so, described metallic contact sheet 4,4 ＇ of total some coil 2 contact in railcar bottom; When the described wiring metal contact disk 4 on coil connectors 21 contact cables, 4 ＇, coil 2 energising, according to the magnetic effect of electric current, coil 2 is inner and produce magnetic field around, due to the polarity in this magnetic field and the polarity of the place ahead permanent magnet 51 different, coil 2 and permanent magnet 51 are attracted each other; Under the interaction of magnetic field force, railcar travels forward; When permanent magnet 51 is positioned at coil 2 central authorities, coil 2 joint 21 is foremost separated with metallic contact sheet 4,4 ＇, and circuit disconnects, and magnetic field disappears; Because the distance between adjacent described metallic contact sheet 4,4 ＇ is different from the distance between adjacent described coil 2, thus there are all the time coil 2 and metallic contact sheet 4,4 ＇ to join, thus keep power; The resistance of series connection on regulating winding 2, changes the electric current on coil 2, thereby the magnetic field size that control coil 2 produces further realizes the control to railcar speed; In addition, this railcar can adopt conventional brake system to realize parking.The present invention is by cable laying in track 3 inside, and difficulty of construction is less; Not only can protect cable, take street area few simultaneously, need not limit the height of traffick; This electromagnetism railcar is jointly fixing, more stable under steam by track and guide plate.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
