Abstract
A friction-free electromagnetic brake device comprises a rotor and a stator. The stator is arranged in the rotor; a plurality of rotor poles are uniformly distributed on the periphery of an inner cavity of the rotor; and the stator is provided with at least two stator magnetic coils with polarity opposite to that of the rotor. According to the utility model, the polarity of the rotor poles installed on the rotor is opposite to that of the magnetic coils mounted on the stator. After the electromagnetic coils of the stator are energized, the rotor poles and the magnetic coils absorb to each other to prevent rotation of wheels, so as to achieve the purpose of braking. Because no friction exists between the stator and the rotor in the utility model, there is no wear, so as to reduce the pollution to the environment; as no brake is used, repair cos is reduced to mitigate the economic burden of the user as well as improve the driving safety performance.
Description
Technical field
The utility model relates to a kind of brake gear, and is particularly a kind of without the friction electromagnetic brake device.
Background technology
Existing automobile is because the rotation of wheel can be travelled at road, and the automobile in travelling often need to be according to driver's requirement slowing-down brake by force.And existing brake operation principle is mainly come self-friction, utilizes the friction of brake block and brake disc (drum), and the kinetic energy that vehicle is advanced converts the heat energy after the friction to, and car is stopped, and the quality of braking effect all is that brake block plays conclusive effect.But brake block can produce a lot of dust in friction process, contain the harmful substance that morphs because of high temperature action in the dust, even contain carcinogen; In addition, the sharp-pointed noise that also can send automobile brake frequently all can produce larger pollution to environment.Simultaneously, brake block belongs to running stores and in use can wear and tear gradually, so need the wear condition of running check brake block, in order to change brake block, has so just improved the expense of maintenance, has increased people's financial burden; When brake block may wear to extreme position, must change, otherwise can reduce the braking effect of vehicle, even cause security incident.
Summary of the invention
The technical problems to be solved in the utility model is for the deficiencies in the prior art, proposes a kind of reduction environmental pollution, reduces maintenance charge usefulness, improves the nothing friction electromagnetic brake device of traffic safety performance.
The technical problems to be solved in the utility model is to realize by the following technical programs, a kind of without the friction electromagnetic brake device, comprise rotor and stator, stator is arranged in the rotor, be characterized in: the inner chamber at rotor circumferentially is evenly distributed with several rotor magnetic poles, is provided with the stator solenoid of at least two settings opposite to rotor magnetic pole polarity at stator.
The technical problems to be solved in the utility model can also come further to realize by the following technical programs, and described stator solenoid is on 2-3 outer surfaces that evenly are arranged on stator.
The technical problems to be solved in the utility model can also be come further realization by the following technical programs, and described rotor magnetic pole is permanent magnet or rotor solenoid.
Compared with prior art, the opposite setting of polarity of the utility model rotor magnetic pole and stator solenoid, the stator solenoid get electric after, stator solenoid and rotor magnetic pole produce interattraction, hinder the rotation of wheel, thereby reach the purpose of brake.The utility model since between stator and the rotor without friction, do not have wearing and tearing, so pollution-free to environment owing to need not the apply the brakes sheet, so reduced the expense of maintenance, alleviated people's financial burden, simultaneously, improved the security performance of people's drivings.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
A kind of without the friction electromagnetic brake device, comprise rotor 1 and stator 3, stator 3 is arranged in the rotor 1, circumferentially is evenly distributed with several rotor magnetic poles 2 at the inner chamber of rotor 1, is provided with at least two stator solenoids 4 with the opposite setting of rotor magnetic pole 2 polarity at stator 3.Described rotor magnetic pole is permanent magnet or rotor solenoid.
Described stator solenoid 4 is on 2-3 outer surfaces that evenly are arranged on stator 3.The quality of braking brake effect is relevant with the size of electric current, and larger by the electric current of stator solenoid 4, magnetic field is stronger, braking moment is just larger, in conjunction with the road conditions of vehicle on road, can be set to square wave, rectangular wave isopulse waveform by electrical current, realize the point of vehicle is stopped.
The car phenomenon occurs to slip when preventing from stopping on the slope, on rotor two-way ratchet mechanism can be set.
