Description
Technical field
The present invention relates to rail type railway traffic vehicular field, specifically, relate to a kind of railroad track vehicular traffic and use motor drive.
Background technology
According to incompletely statistics, 25 Construction of Urban Rail Traffic general planning mileages of China surpass 5000 kilometers, and gross investment is estimated above 8,000 hundred million yuan.Requiring down in sustainable developments such as energy-saving and emission-reduction, environmental protection, saving soils, make up traffic major path between flourishing interregional, regional city, is the great proposition that determines the urbanization development level.At present, except that magnetic suspension train, also do not have efficient, energy-saving and environmental protection, the stable rail traffic vehicles that directly drives at home and abroad, but the magnetic suspension train cost is high, operating cost is high, the economic development situation and the popularization of incompatibility China.This is the weak point of existing rail traffic vehicles.
Summary of the invention
The technical matters that the present invention will solve provides a kind of railroad track vehicular traffic and uses motor drive, and this engine installation cost is low, firm reliable, simple in structure, energy-efficient.
The present invention adopts following technological means to realize goal of the invention:
A kind of railroad track vehicular traffic is used the straight line electric machine actuating device; Comprise track and sleeper, it is characterized in that: also comprise at least two row magnetic pole of the stator and rotor magnetic poles, said magnetic pole of the stator is arranged on the inboard or sleeper upside of said track; Said rotor magnetic pole is fixed in the middle of vehicle two bottom sides or the bottom; And corresponding with the magnetic pole of the stator position, said rotor magnetic pole is provided with excitation coil, and the two ends of the left and right sides of vehicle bottom are respectively arranged with coil pickup.
As the further qualification to the present technique scheme, said magnetic pole of the stator is non-permanent-magnet material, and said vehicle bottom is provided with the rotor adapter plate, and said rotor magnetic pole is installed on the said rotor adapter plate.
As the further qualification to the present technique scheme, said rotor magnetic pole and magnetic pole of the stator adopt the salient pole linear structure.
As the further qualification to the present technique scheme, number is inequality in said magnetic pole of the stator and the rotor magnetic pole equal length.
Compare with existing electric track traffic technique; Advantage of the present invention and good effect are: the present invention is through the coil power supply to rotor magnetic pole; Generate an electromagnetic field, constitute closure with the magnetic pole of the stator magnetic circuit, the magnetic resistance minimum principle makes adjacent stators magnetic pole and rotor magnetic pole produce tractive force; Change the current"on"time of excitation winding or change the power-up sequence of each phase excitation winding, running velocity, service direction, generation electromagnetic braking that just can control vehicle.Each phase winding energising sequential of rotor magnetic pole confirms that by the detected information of coil pickup coil pickup provides running velocity information and control information.The present invention is simple in structure, efficient is high, construction cost is low, stable, prolong life-span of railway and vehicle.
