Description

  The present invention relates to a generator structure of a generator configured by arranging a generator in a cylindrical inner space of a rotor.

  A generator provided in a vehicle includes a rotor in which a permanent magnet is fixed to a cylindrical yoke inner peripheral surface, and an electron generator that is disposed inside the yoke and has a coil wound around a salient pole portion of a core. There is a magnet generator that rotates the rotor to obtain an electromotive force.

(For example, patent document 1).

Further, as shown in FIG. 5, a conventional electron generator 80 includes a core 81 in which a plurality of salient poles I to VIII (eight examples are illustrated in FIG. 5) are radially arranged on a main body 81a, and a power load device. A load coil 82a for supplying electric power to the battery and a charging coil 82b for supplying electric power to the battery, and a plurality of (five examples are shown in FIG. 5) adjacent salient pole portions I to V The load coil 82a is wound, and the charging coil 82b is wound around the remaining adjacent salient pole portions VI to VIII.
Japanese Patent No. 2826943

  By the way, when the battery is in a fully charged state, almost no current flows through the charging coil. At this time, when the magnetic force between the coil and the rotor is considered as a vector, when the load coil and the charging coil are arranged adjacent to each other as in the prior art, the load coil and the rotor While the magnetic force is large, the magnetic force between the charging coil and the rotor becomes close to zero. For this reason, the balance of the magnetic force is unbalanced between the salient pole portions I to V around which the load coil is wound and the salient pole portions VI to VIII around which the charging coil is wound, and the magnetic balance of the entire generator is reduced. Deteriorate. When such a magnetic balance is deteriorated, there is a problem that magnetostrictive sound is generated from the generator and becomes noise. Such noise has a problem in that magnetostriction sound is likely to leak from the opening when an opening for taking in outside air is provided by using a generator room by cooling an engine such as a small two-wheeled vehicle. .

  In order to reduce such magnetostrictive noise, Patent Document 1 balances magnetic balance by winding a load coil (lamp coil) around all salient pole parts including a salient pole part around which a charging coil is wound. I am trying. However, when the electron emission is configured in this manner, magnetostriction noise can be reduced, while the number of salient pole portions around which the load coil is wound is increased by the number of salient pole portions around which the charging coil is wound. Thus, there is a problem that the man-hour is increased.

  In view of the above problems, an object of the present invention is to provide a generator structure that can reduce magnetostriction noise with a simple configuration.

In order to achieve the above object, the generator structure of the generator according to the present invention is provided in a vehicle, and the generator is configured by arranging the generator in the inner space of a rotor formed into a cylindrical shape. The main body is formed in a regular octagon shape whose outer shape is rotationally symmetric with respect to the rotation axis of the rotor , and the outer surface of the main body protrudes from each side of the main body along the inner peripheral surface of the rotor. Te core and configured to have eight salient pole portions disposed at substantially equal intervals, the power load device for a vehicle wound on a portion of the salient pole portion of the eight salient poles It is comprised from the coil for load which supplies electric power, and the coil for charging which winds around the remaining salient pole part of eight salient pole parts and supplies electric power to the charging device of a vehicle. In addition, among the four sets of salient pole portions that are symmetrical with respect to the rotation axis, in one set of salient pole portions, a load coil is wound around both salient pole portions, and the remaining three sets of salient pole portions. In the above, the load coil is wound around one salient pole part, the charging coil is wound around the other salient pole part, and the charging salient part around which the charging coil is wound is wound around the load coil. Disposed between each of the load salient poles and distributed in the circumferential direction of the main body, and distributed and arranged so as to equalize the magnetic force balance in the circumferential direction and stabilize the magnetic balance of the entire generator. Composed.

In the power generation structure configured as described above, an attachment portion for attaching the generator to the vehicle is provided at a position symmetrical with respect to the rotation axis of the core, the core is located on the crankshaft of the engine of the vehicle, and It is preferably configured to be fixed to the crankcase of the engine via an attachment portion so as not to rotate with the crankshaft .

  According to the generator structure of the generator according to the present invention, the load coils and the charging coils are not arranged adjacent to each other as in the prior art, and the charging coils are distributed between the load coils. As a result, the load coils and the charging coils are similarly distributed and arranged, so that even when almost no current flows through the battery, the bias of the magnetic force balance as in the adjacent arrangement is reduced. It is possible to stabilize the magnetic balance of the emitted electrons as compared with those arranged adjacent to each other. For this reason, it is possible to reduce the magnetostrictive sound. In addition, the load coil is wound around the remaining salient pole portion around the salient pole portion around which the charging coil is wound, and each salient pole portion is either a charging coil or a load coil. One is wound. For this reason, compared with the electroluminescent structure which has the salient pole part by which both coils were wound, a man-hour can be reduced and a generator can be comprised.

  Moreover, the attachment part for attaching an emitted electron to a vehicle is provided in the rotationally symmetrical positional relationship with respect to the centerline of a core. Then, each of the load coil and the charging coil is wound around the salient pole part on one side of the core and the salient pole part on the other side divided into two with respect to the center line. As described above, the salient pole portion around which the load coil or the charging coil is wound around the center line having the rotationally symmetrical position of the mounting portion is arranged so as to be distributed between one side and the other side. The magnetic balance between one side and the other side can be balanced. For this reason, a core can be stably attached only by attachment with two attachment parts in this rotationally symmetrical positional relationship. For this reason, the generator which reduced the magnetostriction sound can be comprised, without increasing the man-hour for attaching an emitted electron to a vehicle.

  Next, the generator structure of the generator according to the present invention will be described in more detail. As shown in FIGS. 1 and 3, the generator G includes a rotor 60 and an electron generator 70. The rotor 60 includes a cylindrical yoke 61, and the right end surface of the yoke 61 is attached to the end of the right crankshaft 18 b and is coupled to a washer 67 that can rotate integrally with the crankshaft 18 by a boss 68. The radiator fan 39 and the bolt 69 are coupled to each other so as to be rotatable integrally with the crankshaft 18. Further, permanent magnets 62 and 62 are fixed to the cylindrical inner peripheral surface of the yoke 61.

  The generator 70 includes a core 71 having a main body 71a formed by laminating flat plates formed of a magnetic material and having a regular octagonal shape in plan view, and an opening provided at the center of the main body 71a. The core 71 from 71d is provided on the crankshaft 18 inside the cylinder of the yoke 61, and is screwed into the crankcase 14 by bolts 79 inserted into the bolt insertion holes 71b and 71b. Regardless, it is fixed on the crankshaft 18 without rotating.

  The core 71 is provided with salient poles 71c, 71c,... (I to VIII) projecting radially from the central part of each side in the plan view of the regular octagonal main body 71a. The cylinder 61 is disposed at substantially equal intervals along the inner circumferential surface of the cylinder 61 and faces the permanent magnet 62 provided on the inner circumferential surface of the yoke 61. As described above, the core 71 provided with the salient pole portions 71c, 71c,... Has rotational symmetry (8-fold rotational symmetry) in a plan view outline. In addition, the core 71 has line symmetry, but the connection between salient poles in a rotationally symmetric positional relationship as shown by a one-dot chain line, and the diagonal line of the regular octagonal main body 71a as shown by a two-dot chain line These two types of center lines are line symmetric. Note that the line-symmetric core 71 is bisected by the diagonal line of the main body 71a in plan view, but the eight salient poles 71c, 71c,... Provided in the core 71 are one of the bisected cores 71. And the other side are divided by half (four) respectively. Further, bobbins 73 are respectively provided on the salient pole portions 71c, 71c,. The bobbin 73 is insert-molded using a resin insulating material with respect to the main body 71a, or is molded by powder coating.

  A coil 72 is wound around each of the salient pole portions I to VIII via a bobbin 73 with respect to such a core 71. The coil 72 includes a load coil 72a for supplying power to a power load such as the headlight HL and a charging coil 72b for supplying power to the battery B. The load coil 72a is wound around the five salient pole portions I, II, IV, V, and VII, and the charging coil 72b is wound around the three salient pole portions III, VI, and VIII. The coils 72a and 72b wound around the salient poles are connected to terminals (not shown) through terminal holes 71e, 71e,... Provided in the main body 71a of the core 71, and are electrically connected to each power load via the terminals. Connected.

  The salient pole portions III, VI, and VIII around which the charging coil 72b is wound are distributed and disposed between the salient pole portions I, II, IV, V, and VII around which the load coil 72a is wound. More specifically, the load coil 72a is wound around the salient pole portions VII, II, and IV that are in a rotationally symmetrical positional relationship between the salient pole portions III, VI, and VIII around which the charging coil 72b is wound. One of the load coils 72a divided into two by the center line with respect to the center line which is a connection between the salient pole portions I and V around which the load coil 72a is wound in a rotationally symmetrical positional relationship ( 3 is wound around one salient pole portion VII on the side (upper side in FIG. 3) and around two salient pole portions II and IV on the other side (lower side in FIG. 3). It is wound around two salient pole parts VI and VIII on the other side, and similarly on one salient pole part III on the other (lower side in FIG. 3) side. The three salient pole portions around which the charging coils 72b dispersed in this manner are wound are arranged so as to have a substantially rotationally symmetric (substantially three-fold rotational symmetry) positional relationship. It should be noted that two other load coils 72a and one charging coil 72b are wound around one side and the other side with respect to the other three center lines indicated by the one-dot chain line. Has been.

  The bolt insertion holes 71b and 71b are provided at rotationally symmetric positions with respect to the center line indicated by the two-dot chain line (diagonal line of the main body 71a), and the load coil 72a is divided into two by this center line. One of them (upper side in FIG. 3) is wound around two salient poles V and VII, and the other side (lower side in FIG. 3) is wound around three salient poles I, II and IV, and charging coil 72b Is wound around two salient pole portions VI and VIII on one side (upper side in FIG. 3) and around one salient pole portion III on the other side (lower side in FIG. 3). It should be noted that the center line indicated by the other two two-dot chain lines is also wound around two salient pole portions on one side where the load coil 72a is divided into two, and around three salient pole portions on the other side. The charging coil 72b is also arranged so as to be wound around two salient pole portions on one side and around one salient pole portion on the other side.

  The charging coils 72b are distributed and arranged in this way, but the load coil 72a and the charging coil 72b are connected in series.

  FIG. 4 shows an electric circuit diagram of a two-wheeled vehicle including the generator G. As described above, the generator G is wound around the salient pole portions I, II, IV, V, and VII and connected in series, and is wound around the salient pole portions III, VI, and VIII, respectively. And a charging coil 72b connected to the AC coil. An AC voltage is generated in the load coil 72a and the charging coil 72b by the rotation of the rotor 60.

  The load coil 72a is connected to the power load L via a regulator REG for stabilizing the voltage, and the power from the load coil 72a is consumed by the power load L. Here, the power load L includes the above-mentioned meters, meter illumination lights, blinkers, tail lamps, brake lamps, and the like.

  The load coil 72a is provided with an intermediate tap. A headlight lighting circuit HC provided with a lighting switch SW1 and a beam switch SW2 is connected to the intermediate tap. The headlight lighting circuit HC is configured such that when the lighting switch SW1 is turned off as shown by a dotted line, a current flows through the resistor R and the voltage from the load coil 72a is consumed by the resistor R. The lighting switch SW1 Is turned on as indicated by a solid line, the headlight HL is turned on. Further, when the lighting switch SW1 is on and the beam switch SW2 is off as indicated by a dotted line, only the headlight HL is lit, and when the beam switch SW2 is on as indicated by a solid line, the high beam HI is lit along with the headlight HL. It has become. The intermediate tap is also connected to the regulator REG.

  The charging coil 72b is connected to the battery B, and power from the charging coil 72b is supplied to the battery B so that the battery B can be charged.

  Here, when the charging of the battery B is less than the capacity, the electric power from the charging coil 72b is supplied to the battery B and the battery B is charged. Further, a stable voltage is supplied from the load coil 72a to the power load L via the regulator REG. When the battery B is fully charged, the amount of current flowing through the circuit connected to the charging coil 72b is reduced. Thereby, the magnetic force between the charging coil 72b and the rotor 60 is reduced.

  Further, when the lighting switch SW1 is turned on, a current flows from the intermediate tap to the lamp lighting circuit HC, and the headlight HL is lit regardless of whether the beam switch SW2 is turned on or off. At this time, since the power is supplied to the headlight HL having a high power load (for example, 80 W), the amount of current flowing through the load coil 72a is significantly changed, and the magnetic force between the load coil 72a and the rotor 60 is changed. The ingredient changes greatly. This phenomenon becomes more pronounced when the beam switch SW2 is turned on.

  Here, according to the conventional electron generating structure, as shown in FIG. 5, the load coil 82a is configured to be wound around the adjacent salient pole portions I to V among the plurality of salient pole portions I to VIII. There was a bias in the magnetic balance as a generator, causing magnetostrictive noise.

  According to the electron generating structure of the present invention, the magnetic force vectors of salient pole part I and salient pole part V, which are in a rotationally symmetric positional relationship and around which load coil 72a is wound, cancel each other. The remaining six salient pole portions are different from the coils around which the coils wound around the salient pole portions having a rotationally symmetrical positional relationship are wound around themselves. For this reason, salient poles II and VI, salient poles III and VII, and salient poles IV and VIII, which are in rotationally symmetrical positional relationship, cancel out the magnetic force vector and balance the magnetic balance. The magnetic force vectors of the salient poles II, VII, IV around which the coil 72a is wound are large, and the magnetic force vectors remain on the salient poles II, VII, IV side.

  Here, with respect to the center line connecting the salient pole portions I and V, the salient pole portions II and IV are on the lower side in FIG. 3, and the salient pole portion VII is on the upper side in FIG. 3. As a result, the mutual magnetic force vectors cancel each other and the magnetic force vector remains on the lower side of FIG. 3, but the overall magnetic balance is further balanced.

  The same can be said with reference to the center line with the bolt insertion holes 71b and 71b in a rotationally symmetrical positional relationship. The magnetic force vectors in the rotationally symmetrical positional relationship cancel each other, and the bolt insertion holes 71b and 71b are Although the magnetic force vector remains in the salient pole portion located on the lower side of FIG. 3 among the two divided by the center line having the rotationally symmetrical positional relationship, the magnetic balance is balanced as a whole.

  As described above, according to the electron generating structure according to the present embodiment, the salient pole portions around which the charging coil is wound are distributed between the salient pole portions around which the load coil is wound. For this reason, since the magnetic balance of the generator G can be balanced as compared with the conventional configuration in which the load coil and the charging coil are arranged adjacent to each other, magnetostrictive noise can be reduced. In this embodiment, among the eight salient pole portions 71c, 71c,... Provided on the core 71, the three salient pole portions around which the charging coil 72 is wound are arranged so as to have a substantially rotationally symmetrical positional relationship. The remaining five salient poles around which the load coil 72a is wound are also distributed in a well-balanced manner. By dispersing and arranging in this way, it is possible to effectively balance the magnetic balance, and to effectively reduce magnetostriction noise. In addition, by dispersing the charging coil 72b in this way, charging is performed on one side and the other side that are bisected by the center line with respect to any of the center lines that make the core 71 line-symmetric in plan view. Each of the coil 72b for load and the coil 72a for load is distributed, and the generator 70 which was able to be magnetically balanced as the whole generator can be comprised.

  Further, in this embodiment, the electron generator 70 is configured so that either one of the load coil 72a and the charging coil 72b is wound around each of the salient pole portions I to VIII. For this reason, winding man-hours can be reduced and productivity can be improved as compared with the electron generating structure configured by having a salient pole part around which multiple types of coils are wound, such as winding a load coil around all salient pole parts. be able to.

  Further, the main body 71 a of the core 71 is screwed with the crankcase 14 at two locations, and the bolt insertion holes 71 b and 71 b provided in the main body 71 a are rotationally symmetrical with respect to the center line of the core 71. Provided. Then, each of the load coil and the charging coil is wound around the salient pole part on one side and the salient pole part on the other side of the core 71 which is divided by the center line, It distributes to the other side and the other side. For this reason, the balance of the magnetic balance between one side and the other side can be balanced, and the electron emission 70 can be stabilized only by mounting using the two bolt insertion holes 71b and 71b on the center line. Can be attached to the engine side (crankcase). Thus, the generator G which reduced the magnetostriction sound can be comprised, without increasing the man-hour for attaching the electroluminescent electron 70 to an engine side.

  In the above embodiment, the generator case 38 is provided with the opening 38a so that the outside air is taken into the generator case 38 and the engine 10 is air-cooled. According to the generator structure of the generator according to the present invention, magnetostriction noise is reduced as compared with the conventional case, so that no noise is generated even if the opening 38a is formed larger. Thus, with the generator structure of the generator according to the present invention, the air cooling effect of the engine 10 can be improved when the engine 10 is in the form of air cooling by providing an opening for taking in outside air.

  As mentioned above, although the Example of the generator structure of the generator which concerns on this invention was described, it is not restricted to the form of the said Example. For example, the load coil 72a is wound around the five salient pole portions I, II, IV, V, and VII, and the charging coil 72b is wound around the three salient pole portions III, VI, and VIII. The number of salient poles around which can be wound can be changed as appropriate. When the load coil and the charging coil are wound around the four salient pole portions, the charging coil is dispersed between the load coils by alternately arranging the charging coil and the load coil in the circumferential direction. In addition, the same number of coils are allocated to one side and the other side with respect to the center line, so that the balance of the magnetic balance can be achieved. At this time, the four salient pole portions around which the charging coil is wound are dispersedly arranged so as to have a rotationally symmetric (4-fold rotational symmetry) positional relationship. When there are six load coils and two charge coils, the same coil is wound around the salient poles in a rotationally symmetrical positional relationship so that the charge coils are dispersed among the load coils. In addition, the same number of coils are allocated to one side and the other side with respect to the center line, so that the balance of the magnetic balance can be achieved. At this time, the two salient pole portions around which the charging coil is wound are dispersedly arranged so as to have a rotationally symmetrical (two-fold rotationally symmetric) positional relationship. In this way, even if the number of salient poles around which the charging coil and the load coil are wound is changed, the balance of the magnetic balance of the whole of the generated electrons 70 can be balanced, and the center as in the above embodiment can be achieved. Electrons can be stably attached to the engine side by attachment using two bolt insertion holes provided in a rotationally symmetrical positional relationship with respect to the line. Note that the number of salient poles is not limited to eight, and can be changed as appropriate. Similar effects can be obtained by arranging the charging coils in a distributed manner between the load coils in the same manner as in the above embodiment. .
