BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an in-wheel system for a motor vehicle in which a motor and an alternator are fused. More particularly, the conventional motor includes a stator core formed of a strong magnetic iron core, In the present invention, in the case of the in Alternator type & out motor type, two rotors are placed so that the first rotor is composed of a stator for the motor and a magnetic force And the second rotor is formed of a magnetic material or a conductor, and the first and second rotors simultaneously rotate with the power generating stator formed of the complex soft material or the non-magnetic material sandwiched therebetween A strong magnetic field passes through the generator stator and is stuck due to a strong magnetic field between the first rotor and the generator stator and the second rotor It is possible to suppress the cogging phenomenon and the eddy current between the winding coils between the first rotor and the generator stator and the second rotor, to reduce the rotation resistance and to increase the rotation speed . It is possible to increase the travel distance by adding the charging function while driving in an electric car or an electric motorcycle which requires both driving and charging simultaneously. Since the stator of the motor is formed as an outer case, it is larger than in Motor type & out Alternator type To an in-wheel motor vehicle for a railway vehicle in which a motor and an alternator are integrated to generate a magnetic force.

On the other hand, in the case of the in-motor type & out Alternator type, the second rotor is omitted while the first rotor and the rotor rotor remain, and the motor stator and the generator stator are exchanged with each other, The present invention relates to an in-wheel system of a railway vehicle in which a motor and an alternator are fused so as to generate a larger electromotive force by increasing the number of magnets than in the case of an alternator type & out motor type.

The present invention relates to an in-wheel system for a motor vehicle in which a motor and an alternator are fused. The magnitude of the electromotive force generated by the generator is proportional to the strength of the magnetic field, the length of the conductor and the relative speed of the magnetic field and the conductor.

Therefore, the electromotive force can be increased by increasing the intensity of the magnetic field, by forming the conductor longer, or by increasing the relative speed of the magnetic field and the conductor. Generally, the relative speed of the magnetic field and the conductor is increased to increase the electromotive force. To achieve this, the rotation speed of the rotor must be increased. In this case, when the low speed rotation power such as the tidal force, I could not get it.

A generator capable of obtaining a desired electromotive force by using two rotors has been developed. An example of the generator shown in Fig. 10-1454805 is shown in Fig.

The generator shown in FIG. 4 has a structure in which an electromotive force is obtained at a low rotational speed by rotating the rotor 120 having a magnet and the internal casing 150 as a magnetic body in the same direction. Advantages include a rotor 120 having a magnet, Magnetic coils wound around the core of the stator 130 formed of a composite soft material or a non-magnetic material between the synchronous rotating bodies, i.e., the inner casing 150, which is the inner casing 150, It is possible to eliminate the attraction to attach to the coiled stator 130 while generating electromotive force, to suppress the cogging phenomenon and the eddy current, and to reduce the heat generation effect and the rotation resistance, thereby increasing the power generation efficiency have.

However, the above-described conventional generator is useful for engine power generation, wind power generation, and tidal power generation because it merely possesses the function of a simple alternator that does not incorporate the function of a motor. However, in order to use it as an electric vehicle or an electric vehicle, An in-wheel system for fused trains is needed.

SUMMARY OF THE INVENTION The present invention has been devised in order to solve the problems of the conventional art described above. Generally, motor and alternator can not be fused, and they have been manufactured in their own form and used together.

It is an object of the present invention to provide an alternator coupled to a motor function to generate electric power when a motor and an alternator function are combined into a single body to rotate the motor.

To this end, a second rotor is provided on the outer side of the rotating shaft, a generator stator is provided on the outer side of the first rotor, a first rotor is disposed on the outer side of the generator stator, A stator for a motor is provided and a rotor housing is provided outside a stator for a motor so that a stator for power generation and a stator for motor can simultaneously obtain an electromotive force and a magnetomotive force.

The motor function and the alternator function combined in a single body are formed by a first rotor and a magnetic body or a conductor formed by bi-directionally forming magnets in order to increase the strength of the magnetic field, to form a lot of conductors, or to increase the relative speed of the magnetic field and the conductor. And a rotor housing formed of a first rotor, a second rotor and a magnetic body or a conductor. The stator for power generation, which is disposed between the first rotor and the second rotor, is wound around a complex soft material or a non- It is very important that the first rotor, the second rotor, and the rotor housing are rotated at the same time to be fixedly coupled with the rotating shaft, and in particular, to the stator for power generation, A winding coil is formed and the attraction force for stopping the first rotor, the generator stator, The electromotive force of the outer magnet of the first rotor reaches the second rotor to generate a strong electromotive force. At this time, by suppressing the cogging torque and the eddy current and reducing the high temperature and the rotational resistance, And to provide an in-wheel system for a railway vehicle in which a motor and an alternator can be further obtained.

On the other hand, in the case of the in-motor type & out Alternator type, the second rotor is omitted while the first rotor and the rotor housing remain intact, and the motor stator and the generator stator are exchanged with each other, To provide an in-wheel motor for a motor vehicle that combines a motor and an alternator to generate a larger electromotive force than in the case of the " in Alternator " type motor by increasing the number of magnets.

In order to achieve the object of the present invention, an in-wheel motor vehicle for a railway vehicle in which a motor and an alternator are fused can be provided with a rotating shaft that rotates at the center of the frame.

The rotary shaft may be supported by a rotary shaft support L and a rotary shaft support R having bearings mounted on the right and left sides thereof.

The second rotor is formed of a conductor or a magnetic material on the radial side and the left side is engaged with the outer peripheral surface of the rotary shaft support L using the coupling bearing and the coupling member of the second rotor side plate L, (Fixed) to be fixed to the rotary shaft by using the coupling bearing and the binding body of the side plate R. [

The left side of the power generator stator side plate L is connected to the outer circumferential surface of the rotary shaft support L by a coupling bearing and a coupling member of the power generator stator side plate L, And the right side of the power generator stator side plate R can be coupled to the outer circumferential surface of the rotating shaft in a slip state by using a coupling bearing and a coupling member of the power generator stator side plate R. [

The first rotor side plate L is engaged with the outer peripheral surface of the rotary shaft support L using a coupling bearing and a coupling member of the first rotor side plate L, And the right side can be coupled so that the first rotor side plate R is fixed to the rotary shaft by using a coupling bearing and a coupling member of the first rotor side plate R. [

The left side of the motor stator side plate L is connected to the outer peripheral surface of the rotating shaft support L and the slippery side of the motor shaft using the coupling bearing and the coupling member of the motor stator side plate L. [ And the right side of the motor stator side plate R can be coupled to the outer circumferential surface of the rotating shaft in a slip state by using the coupling bearing and the coupling member of the stator side plate R for motor.

The left side of the rotor housing is joined to the outer circumferential surface of the rotary shaft support L in a slip state by using a coupling member and a coupling member of the side housing L, And the side housing R may be fixedly coupled to the rotary shaft by using a coupling bearing and a coupling member of the side housing R. [

In addition, when the first rotor is formed into a magnetic body, the second rotor may be formed of a magnetic material so as to increase the intensity of the relatively larger magnetic field or increase the electromotive force.

The input wiring for the motor and the output wiring for power generation are wound coils wound around the non-magnetic material core or the composite soft material of the winding coils and the generator stator wound around the magnetic core of the stator for the motor, Through the coupling bearing of the first electromagnetic side plate L, the coupling bearing of the stator side plate L for power generation, the side surface of the coupling bearing of the side housing L, or the sleeve, and can be safely drawn to the outside.

On the other hand, in the case of the in-motor type & out alternator type, the second rotor may be omitted while the first rotor and the rotor housing remain intact. In order to form the generator stator into an outer shape, They can be installed by exchanging mutual positions.

According to the in-wheel motor system for a motor vehicle in which the motor and the alternator are fused, the first rotor, the second rotor, and the rotor housing, which are directly fixed to the rotary shaft, rotate simultaneously in the same direction A magnetostrictive force is generated between the rotor housing and the stator for the motor and the first rotor by the external power source supplied to the stator for the motor to operate the rotating force, An electromotive force is generated between the stator of the generator and the second rotor.

That is, the power generating stator having the core formed of the complex soft material or the non-magnetic material is left as it is, and the first rotor is formed of the magnetic material, the second rotor is formed of the conductor or the magnetic material, A strong magnetic field passes through the generator stator as the second rotor rotates at the same time and the attraction between the first rotor and the second rotor due to the strong magnetic field is eliminated, The cogging phenomenon and the eddy current between the winding coils and the second rotors of the stator for the stator can be eliminated, the rotational resistance can be reduced and the rotational speed can be increased more than that of the conventional generator. Thus, desired electromotive force can be obtained, There is an advantage of saving power energy.

Therefore, by implementing the motor function and the alternator functions simultaneously in the in-wheel motor for the electric vehicle in which the motor and the alternator are fused, it is possible to increase the mileage by adding the charging function while operating in the electric car and the electric motorcycle, It is an energy fusion technology.

In the case of the in-motor type & out alternator type, the second rotor is omitted while the first rotor and the rotor rotor remain, and the position of the motor stator and the generator stator are exchanged with each other, By increasing the number of magnets, it is possible to generate more electromotive force than in the case of in Alternator type & out motor type.
