Magnetic suspension bearing

Technical field

The present invention relates to a kind of magnetic suspension bearing and magnetic-suspension automobile field.

Background technique

At present, vehicle and bearing are mechanically all common ball bearing or roller bearings, have not had magnetic suspension bearing, have not also had magnetic-suspension automobile.

2005, I applied for the patent of " magnetic suspension bearing and magnetic-suspension automobile ", and the patent No. is 200510102793.9, because my substantive examination request letter submitted to one's superior must be more late, on April 21st, 2008, just receive the examination as to substances program notice of Patent Office, also do not receive so far substantive examination information

The patent of current application is identical with my patent name of application in 2005, and reason is that the patent of current application is repairing and the expansion of the patent to application in 2005.

Summary of the invention

The technical problem to be solved in the present invention is that the bearing of Automobile wheel is replaced with magnetic suspension bearing, make aloft (except the wheel) of vehicle body suspension of automobile, like this, automobile traveling gets up, friction and the resistance of bearing are greatly alleviated, alleviate vibrations, also improved motion speed, and be beneficial to energy-conservation and environmental protection.

The principle of magnetic suspension bearing derives from magnetic suspension train, so must first illustrate the principle of magnetic suspension train here.

The cardinal principle that train magnetic force floats method is: at car bottom, high-intensity magnet is installed, and between two guide rails, lay continuously coil, in the time passing to powerful electric current in coil, the magnet of car bottom will be repelled in the magnetic field that it produces, train is floated and no longer contact with rail, Here it is Electromagnetic levitation.

Also have a kind of method, ground coil no electric circuit stream, in the time that train is run at high speed, at the bottom of car, the magnetic field of magnet induces powerful electric current in coil, can make equally train float, and this method is called electrodynamics suspension method.

We are used in the principle of magnetic suspension train on automobile, are used in specifically on the bearing of automobile, and the method for its application illustrates by reference to the accompanying drawings.

Accompanying drawing explanation

Fig. 1 is the simple and easy operation schematic diagram of magnetic suspension train;

Fig. 2 is the distortion schematic diagram of magnetic suspension train guide rail;

Fig. 3 is the operation schematic diagram of magnetic suspension train on circumferential guide rail;

Fig. 4 is the magnetic suspension bearing of making according to Fig. 3.Also can be described as the cross-sectional schematic diagram of magnetic suspension bearing;

Fig. 5 is that the side of magnetic suspension bearing is cutd open schematic diagram.The namely vertical profile schematic diagram of the magnetic suspension bearing shown in Fig. 4.

In Fig. 1, A line is the guide rail of having laid coil, and B is the train that magnet has been installed, and C is suspension area.We first become guide rail A into endless, namely allow the eternal race of train not be at the end, and this just must become circumferential by guide rail A, as Fig. 2.Then train B is removed in the circumference of guide rail, allow it on guide rail, move, as Fig. 3.In Fig. 3, A is the guide rail of having laid coil, and B is the train that magnet has been installed, and C is suspension area.We regard it as the epitome of magnetic suspension train as this Fig. 3.

We transform into the epitome of this magnetic suspension train into an automobile bearing.Fig. 3 middle guide A is used as to the shell of bearing, train B is as the spindle nose of automobile axle shaft, and suspension area C replaces ball or roller, as Fig. 4.Fig. 4 is the sectional elevation of magnetic suspension bearing.In Fig. 4,1 is the coil of installing on magnetic suspension bearing shell, the 2nd, and automobile axle shaft spindle nose, the 3rd, the magnet of installing on semi-shaft shaft head circumferential surface, the 4th, suspension area, the 5th, shell, the 6th, the axostylus axostyle of automobile axle shaft.

In Fig. 4, the 4th, suspension area, the part beyond this suspension area, comprises 1 (coil), 5 (shells), is connected with tire, this belongs to wheel part.Suspension area, with interior part, comprises 3 (magnet), B (spindle nose), is spindle nose part, is connected with semiaxis after automobile.Like this, we utilize the Electromagnetic levitation of magnetic suspension train, pass to powerful electric current to 1 (coil), and because there is corresponding magnet on opposite, rear axle spindle nose B portion will be suspended in the air, Here it is magnetic suspension bearing.This bearing not only can be used on automotive wheel, and can be used on train wheel, the vehicle in mine and subway, tunnel and other vehicle and mechanically can apply.

The front-wheel of magnetic-suspension automobile also must be installed same magnetic suspension bearing.Like this, in the middle of each wheel of an automobile, 1-2 magnetic suspension bearing is installed, utilized Electromagnetic levitation, will be by aloft (but tire lands) of whole vehicle body suspension.Skyborne this vehicle body suspension automobile is referred to as magnetic-suspension automobile by we.

Travelling of this magnetic-suspension automobile can be by the tire beyond bearing suspension area to driving front, and by suspension area, with the axially opposite direction transmission of tire of interior spindle nose and half, automobile just can travel.

As required, the coil on magnetic suspension bearing and magnet can be replaced.

Not transmission device still of magnetic suspension bearing, and be power plant indirectly.

Embodiment

Take Fig. 5 as example, Fig. 5 is a kind of sectional view of magnetic suspension bearing, namely the longitudinal section of the magnetic suspension bearing shown in Fig. 4.In Fig. 5, the 5th, the shell of magnetic suspension bearing; The 1st, the coil of installing on shell; The 2nd, the spindle nose of magnetic suspension bearing, the namely spindle nose of semiaxis after automobile; The 3rd, the magnet of installing on the circumferential surface of spindle nose; The 4th, suspension area; The 6th, the axostylus axostyle of automobile axle shaft; The 7th, the axostylus axostyle that geared wheel is rolled forward; The 8th, the ball of magnetic suspension bearing; The 9th, the clamping plate of ball and track.Pass to powerful electric current to the coil in Fig. 5, the spindle nose of magnetic suspension bearing has just been suspended in the air, and ball is equipped with in the both sides of spindle nose, and this is a kind of magnetic suspension bearing.If install this bearing 1-2 in the middle of each wheel of automobile, when automobile running, the ball of bearing both sides not only plays booster action to the rolling of wheel, and will play strong supporting effect to swinging of vehicle body.Tire part beyond bearing suspension area and suspension area is supporting all heavy burdens of vehicle body.In Fig. 5, the 7th, the semiaxis by tire to driving front, can geared wheel roll forward, when geared wheel is rolled forward, can the opposite direction transmission to tire rolling by semiaxis and spindle nose, this can give the tire enhancing power that rolls forward.The all available electrical energy transmissions or be equipped with internal-combustion engine transmission of the mode of this two places transmission.

The size of magnetic suspension bearing is installed in wheel and how much should determines according to the size of vehicle and carrying capacity.

Another kind of mode of execution is: take Fig. 5 as example, give the obstructed electric current of coil of magnetic suspension bearing, first high-speed drive is equipped with the automobile axle shaft of magnet, because the magnetic field of magnet induces powerful electric current in coil, can make equally semi-shaft shaft head be suspended in the air.One or more this magnetic suspension bearing is installed in each wheel, just by whole vehicle body suspension aerial.With semiaxis and wheel reversing drive simultaneously, automobile just can travel.

Magnetic suspension train is that suspension is skyborne, has not wanted guide rail but be just not equal to.Too, special ball bearing should play booster action to magnetic-suspension automobile.For example, can not be suspended in when aerial when the coil blackout of magnetic suspension bearing or other reason make automobile axle shaft spindle nose, special ball bearing will be enabled moment; In the time that magnetic suspension bearing is enabled, ball bearing will be abandoned moment.

Another bearing fit mode is: common ball bearing, in the situation that keeping appropriate gap between ball and axle housing, then is equipped with magnetic suspension bearing, and namely ball bearing is synchronizeed and used with magnetic suspension bearing.Because magnetic suspension bearing has alleviated the pressure of vehicle body to ball bearing, thus frictional force also just alleviated, equally can energy-saving run.This is again a kind of application mode of magnetic suspension bearing.

When a magnet is during near superconductor, in superconductor, can produce powerful electric current, magnet is had to repulsive interaction.This repulsive force can make magnet be suspended in the air.Magnetic suspension train has just adopted this technology, so the bearing of magnetic-suspension automobile also can adopt this technology.

Its mode of execution is: change the coil of the magnetic suspension bearing described in Fig. 5 into superconductor, like this, superconductor has just had repulsive interaction to corresponding magnet, and this is also a kind of magnetic suspension bearing.(superconductor and corresponding magnet can all be replaced).When one or two magnetic suspension bearing is so installed in each wheel of automobile, just can be by the vehicle body suspension of automobile aloft, then with electric energy or be equipped with internal-combustion engine energy by wheel to driving front, by the opposite direction transmission of half axial wheel, automobile just can travel.
